For post-installation verification and troubleshooting, please see the :ref:`Barometer post installation guide `. Barometer Docker Images Description ----------------------------------- .. Describe the specific features and how it is realised in the scenario in a brief manner .. to ensure the user understand the context for the user guide instructions to follow. Barometer Collectd Image ^^^^^^^^^^^^^^^^^^^^^^^^ The barometer collectd docker image gives you a collectd installation that includes all the barometer plugins. .. note:: The Dockerfile is available in the docker/barometer-collectd directory in the barometer repo. The Dockerfile builds a CentOS 8 docker image. The container MUST be run as a privileged container. Collectd is a daemon which collects system performance statistics periodically and provides a variety of mechanisms to publish the collected metrics. It supports more than 90 different input and output plugins. Input plugins retrieve metrics and publish them to the collectd deamon, while output plugins publish the data they receive to an end point. Collectd also has infrastructure to support thresholding and notification. Collectd docker image has enabled the following collectd plugins (in addition to the standard collectd plugins): * hugepages plugin * Open vSwitch events Plugin * Open vSwitch stats Plugin * mcelog plugin * PMU plugin * RDT plugin * virt * SNMP Agent * Kafka_write plugin Plugins and third party applications in Barometer repository that will be available in the docker image: * Open vSwitch PMD stats * ONAP VES application * gnocchi plugin * aodh plugin * Legacy/IPMI InfluxDB + Grafana Docker Images ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The Barometer project's InfluxDB and Grafana docker images are 2 docker images that database and graph statistics reported by the Barometer collectd docker. InfluxDB is an open-source time series database tool which stores the data from collectd for future analysis via Grafana, which is a open-source metrics anlytics and visualisation suite which can be accessed through any browser. VES + Kafka Docker Images ^^^^^^^^^^^^^^^^^^^^^^^^^ The Barometer project's VES application and Kafka docker images are based on a CentOS 7 image. Kafka docker image has a dependancy on `Zookeeper `_. Kafka must be able to connect and register with an instance of Zookeeper that is either running on local or remote host. Kafka recieves and stores metrics recieved from Collectd. VES application pulls latest metrics from Kafka which it normalizes into VES format for sending to a VES collector. Please see details in :ref:`VES Application User Guide ` Installing Docker ----------------- .. Describe the specific capabilities and usage for feature. .. Provide enough information that a user will be able to operate the feature on a deployed scenario. .. note:: The below sections provide steps for manual installation and configuration of docker images. They are not neccessary if docker images were installed with use of Ansible-Playbook. On Ubuntu ^^^^^^^^^ .. note:: * sudo permissions are required to install docker. * These instructions are for Ubuntu 16.10 To install docker: .. code:: bash $ sudo apt-get install curl $ sudo curl -fsSL https://get.docker.com/ | sh $ sudo usermod -aG docker $ sudo systemctl status docker Replace above with an appropriate user name. On CentOS ^^^^^^^^^^ .. note:: * sudo permissions are required to install docker. * These instructions are for CentOS 7 To install docker: .. code:: bash $ sudo yum remove docker docker-common docker-selinux docker-engine $ sudo yum install -y yum-utils device-mapper-persistent-data lvm2 $ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo $ sudo yum-config-manager --enable docker-ce-edge $ sudo yum-config-manager --enable docker-ce-test $ sudo yum install docker-ce $ sudo usermod -aG docker $ sudo systemctl status docker Replace above with an appropriate user name. .. note:: If this is the first time you are installing a package from a recently added repository, you will be prompted to accept the GPG key, and the key’s fingerprint will be shown. Verify that the fingerprint is correct, and if so, accept the key. The fingerprint should match060A 61C5 1B55 8A7F 742B 77AA C52F EB6B 621E 9F35. Retrieving key from https://download.docker.com/linux/centos/gpg Importing GPG key 0x621E9F35: .. :: Userid : "Docker Release (CE rpm) " Fingerprint: 060a 61c5 1b55 8a7f 742b 77aa c52f eb6b 621e 9f35 From : https://download.docker.com/linux/centos/gpg Is this ok [y/N]: y Manual proxy configuration for docker ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. note:: This applies for both CentOS and Ubuntu. If you are behind an HTTP or HTTPS proxy server, you will need to add this configuration in the Docker systemd service file. 1. Create a systemd drop-in directory for the docker service: .. code:: bash $ sudo mkdir -p /etc/systemd/system/docker.service.d 2. Create a file called /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable: .. code:: bash [Service] Environment="HTTP_PROXY=http://proxy.example.com:80/" Or, if you are behind an HTTPS proxy server, create a file called /etc/systemd/system/docker.service.d/https-proxy.conf that adds the HTTPS_PROXY environment variable: .. code:: bash [Service] Environment="HTTPS_PROXY=https://proxy.example.com:443/" Or create a single file with all the proxy configurations: /etc/systemd/system/docker.service.d/proxy.conf .. code:: bash [Service] Environment="HTTP_PROXY=http://proxy.example.com:80/" Environment="HTTPS_PROXY=https://proxy.example.com:443/" Environment="FTP_PROXY=ftp://proxy.example.com:443/" Environment="NO_PROXY=localhost" 3. Flush changes: .. code:: bash $ sudo systemctl daemon-reload 4. Restart Docker: .. code:: bash $ sudo systemctl restart docker 5. Check docker environment variables: .. code:: bash sudo systemctl show --property=Environment docker Test docker installation ^^^^^^^^^^^^^^^^^^^^^^^^ .. note:: This applies for both CentOS and Ubuntu. .. code:: bash $ sudo docker run hello-world The output should be something like: .. code:: bash Trying to pull docker.io/library/hello-world...Getting image source signatures Copying blob 0e03bdcc26d7 done Copying config bf756fb1ae done Writing manifest to image destination Storing signatures Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/ Build and Run Collectd Docker Image ----------------------------------- Collectd-barometer flavors ^^^^^^^^^^^^^^^^^^^^^^^^^^ Before starting to build and run the Collectd container, understand the available flavors of Collectd containers: * barometer-collectd - stable release, based on collectd 5.12 * barometer-collectd-latest - release based on collectd 'main' branch * barometer-collectd-experimental - release based on collectd 'main' branch that can also include a set of experimental (not yet merged into upstream) pull requests .. note:: Experimental container is not tested across various OS'es and the stability of the container can change. Usage of experimental flavor is at users risk. Stable `barometer-collectd` container is intended for work in production environment as it is based on latest collectd official release. `barometer-collectd-latest` and `barometer-collectd-experimental` containers can be used in order to try new collectd features. All flavors are located in `barometer` git repository - respective Dockerfiles are stored in subdirectories of `docker/` directory .. code:: bash $ git clone https://gerrit.opnfv.org/gerrit/barometer $ ls barometer/docker|grep collectd barometer-collectd barometer-collectd-latest barometer-collectd-experimental .. note:: Main directory of barometer source code (directory that contains 'docker', 'docs', 'src' and systems sub-directories) will be referred as ```` Download the collectd docker image ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ If you wish to use a pre-built barometer image, you can pull the barometer image from `dockerhub `_ .. code:: bash $ docker pull opnfv/barometer-collectd Build stable collectd container ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. code:: bash $ cd /docker/barometer-collectd $ sudo docker build -t opnfv/barometer-collectd --build-arg http_proxy=`echo $http_proxy` \ --build-arg https_proxy=`echo $https_proxy` --network=host -f Dockerfile . .. note:: In the above mentioned ``docker build`` command, http_proxy & https_proxy arguments needs to be passed only if system is behind an HTTP or HTTPS proxy server. Check the docker images: .. code:: bash $ sudo docker images Output should contain a barometer-collectd image: .. code:: REPOSITORY TAG IMAGE ID CREATED SIZE opnfv/barometer-collectd latest 05f2a3edd96b 3 hours ago 1.2GB centos 7 196e0ce0c9fb 4 weeks ago 197MB centos latest 196e0ce0c9fb 4 weeks ago 197MB hello-world latest 05a3bd381fc2 4 weeks ago 1.84kB .. note:: If you do not plan to use `barometer-collectd-latest` and `barometer-collectd-experimental` containers, then you can proceed directly to section `Run the collectd stable docker image`_ Build barometer-collectd-latest container ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. code:: bash $ cd $ sudo docker build -t opnfv/barometer-collectd-latest \ --build-arg http_proxy=`echo $http_proxy` \ --build-arg https_proxy=`echo $https_proxy` --network=host -f \ docker/barometer-collectd-latest/Dockerfile . .. note:: For `barometer-collectd-latest` and `barometer-collectd-experimental` containers proxy parameters should be passed only if system is behind an HTTP or HTTPS proxy server (same as for stable collectd container) Build barometer-collectd-experimental container ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The barometer-collectd-experimental container use the ``main`` branch of collectd, but allows the user to apply a number of pull requests, which are passed via the COLLECTD_PULL_REQUESTS build arg, which is passed to docker as shown in the example below. COLLECTD_PULL_REQUESTS should be a comma-delimited string of pull request IDs. .. code:: bash $ cd $ sudo docker build -t opnfv/barometer-collectd-experimental \ --build-arg http_proxy=`echo $http_proxy` \ --build-arg https_proxy=`echo $https_proxy` \ --build-arg COLLECTD_PULL_REQUESTS=1234,5678 \ --network=host -f docker/barometer-collectd-experimental/Dockerfile . .. note:: For `barometer-collectd-latest` and `barometer-collectd-experimental` containers proxy parameters should be passed only if system is behind an HTTP or HTTPS proxy server (same as for stable collectd container) Build collectd-6 ^^^^^^^^^^^^^^^^ The barometer-collectd-experimental Dockerfile can be used to build collectd-6.0, which is currently under development. In order to do this, the ``COLLECTD_FLAVOR`` build arg can be passed to the docker build command. The optional ``COLLECTD_PULL_REQUESTS`` arg can be passed as well, to test proposed patches to collectd. .. code:: bash $ cd $ sudo docker build -t opnfv/barometer-collectd-6 \ --build-arg COLLECTD_FLAVOR=collectd-6 \ --build-arg COLLECTD_PULL_REQUESTS=1234,5678 \ --network=host -f docker/barometer-collectd-experimental/Dockerfile . The instructions for running the collectd-6 container are the same as for the collectd-experimental container. There are a few useful build args that can be used to further customise the collectd-6 build: * **COLLECTD_CONFIG_CMD_ARGS** For testing with new plugins for collectd-6, as un-ported plugins are disabled by default. This new option lets the ./configure command be run with extra args, e.g. --enable-cpu --enable-, which means that plugin can be enabled for the PR that is being tested. * **COLLECTD_TAG** This overrides the default tag selected by the flavors, and allows checking out out an arbitrary branch (e.g. PR branch instead of using the ``COLLECTD_PULL_REQUESTS`` arg, which rebases each PR on top of the nominal branch. To check out a PR, use the following args with the docker build command: ``--build-arg COLLECTD_TAG=pull//head`` Run the collectd stable docker image ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. code:: bash $ cd $ sudo docker run -ti --net=host -v \ `pwd`/src/collectd/collectd_sample_configs:/opt/collectd/etc/collectd.conf.d \ -v /var/run:/var/run -v /tmp:/tmp -v /sys/fs/resctrl:/sys/fs/resctrl \ --privileged opnfv/barometer-collectd .. note:: The docker collectd image contains configuration for all the collectd plugins. In the command above we are overriding /opt/collectd/etc/collectd.conf.d by mounting a host directory src/collectd/collectd_sample_configs that contains only the sample configurations we are interested in running. *If some dependencies for plugins listed in configuration directory aren't met, then collectd startup may fail(collectd tries to initialize plugins configurations for all given config files that can be found in shared configs directory and may fail if some dependency is missing).* If `DPDK` or `RDT` can't be installed on host, then corresponding config files should be removed from shared configuration directory (`/src/collectd/collectd_sample_configs/`) prior to starting barometer-collectd container. By example: in case of missing `DPDK` functionality on the host, `dpdkstat.conf` and `dpdkevents.conf` should be removed. Sample configurations can be found at: https://github.com/opnfv/barometer/tree/master/src/collectd/collectd_sample_configs List of barometer-collectd dependencies on host for various plugins can be found at: https://wiki.anuket.io/display/HOME/Barometer-collectd+host+dependencies The Resource Control file system (/sys/fs/resctrl) can be bound from host to container only if this directory exists on the host system. Otherwise omit the '-v /sys/fs/resctrl:/sys/fs/resctrl' part in docker run command. More information about resctrl can be found at: https://github.com/intel/intel-cmt-cat/wiki/resctrl Check your docker image is running .. code:: bash sudo docker ps To make some changes when the container is running run: .. code:: bash sudo docker exec -ti /bin/bash Run the barometer-collectd-latest docker image ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Run command for ``barometer-collectd-latest`` container is very similar to command used for stable container - the only differences are name of the image and location of the sample configuration files (as different version of collectd plugins requiring different configuration files) .. code:: bash $ cd $ sudo docker run -ti --net=host -v \ `pwd`/src/collectd/collectd_sample_configs-latest:/opt/collectd/etc/collectd.conf.d \ -v /var/run:/var/run -v /tmp:/tmp -v /sys/fs/resctrl:/sys/fs/resctrl \ --privileged opnfv/barometer-collectd-latest .. note:: Barometer collectd docker images are sharing some directories with host (e.g. /tmp) therefore only one of collectd barometer flavors can be run at a time. In other words, if you want to try `barometer-collectd-latest` or `barometer-collectd-experimental` image, please stop instance of `barometer-collectd(stable)` image first. The Resource Control file system (/sys/fs/resctrl) can be bound from host to container only if this directory exists on the host system. Otherwise omit the '-v /sys/fs/resctrl:/sys/fs/resctrl' part in docker run command. More information about resctrl can be found at: https://github.com/intel/intel-cmt-cat/wiki/resctrl Run the barometer-collectd-experimental docker image ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Barometer-collectd-experimental container shares default configuration files with 'barometer-collectd-latest' equivalent but some of experimental pull requests may require modified configuration. Additional configuration files that are required specifically by experimental container can be found in `docker/barometer-collectd-experimental/experimental-configs/` directory. Content of this directory (all \*.conf files) should be copied to ``src/collectd/collectd_sample_configs-latest`` directory before first run of experimental container. .. code:: bash $ cd $ cp docker/barometer-collectd-experimental/experimental-configs/*.conf \ src/collectd/collectd_sample_configs-latest When configuration files are up to date for experimental container, it can be launched using following command (almost identical to run-command for ``latest`` collectd container) .. code:: bash $ cd $ sudo docker run -ti --net=host -v \ `pwd`/src/collectd/collectd_sample_configs-latest:/opt/collectd/etc/collectd.conf.d \ -v /var/run:/var/run -v /tmp:/tmp -v /sys/fs/resctrl:/sys/fs/resctrl --privileged \ opnfv/barometer-collectd-experimental .. note:: The Resource Control file system (/sys/fs/resctrl) can be bound from host to container only if this directory exists on the host system. Otherwise omit the '-v /sys/fs/resctrl:/sys/fs/resctrl' part in docker run command. More information about resctrl can be found at: https://github.com/intel/intel-cmt-cat/wiki/resctrl Build and Run InfluxDB and Grafana docker images ------------------------------------------------ Overview ^^^^^^^^ The barometer-influxdb image is based on the influxdb:1.3.7 image from the influxdb dockerhub. To view detils on the base image please visit `https://hub.docker.com/_/influxdb/ `_ Page includes details of exposed ports and configurable enviromental variables of the base image. The barometer-grafana image is based on grafana:4.6.3 image from the grafana dockerhub. To view details on the base image please visit `https://hub.docker.com/r/grafana/grafana/ `_ Page includes details on exposed ports and configurable enviromental variables of the base image. The barometer-grafana image includes pre-configured source and dashboards to display statistics exposed by the barometer-collectd image. The default datasource is an influxdb database running on localhost but the address of the influxdb server can be modified when launching the image by setting the environmental variables influxdb_host to IP or hostname of host on which influxdb server is running. Additional dashboards can be added to barometer-grafana by mapping a volume to /opt/grafana/dashboards. Incase where a folder is mounted to this volume only files included in this folder will be visible inside barometer-grafana. To ensure all default files are also loaded please ensure they are included in volume folder been mounted. Appropriate example are given in section `Run the Grafana docker image`_ Download the InfluxDB and Grafana docker images ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ If you wish to use pre-built barometer project's influxdb and grafana images, you can pull the images from https://hub.docker.com/r/opnfv/barometer-influxdb/ and https://hub.docker.com/r/opnfv/barometer-grafana/ .. note:: If your preference is to build images locally please see sections `Build InfluxDB Docker Image`_ and `Build Grafana Docker Image`_ .. code:: bash $ docker pull opnfv/barometer-influxdb $ docker pull opnfv/barometer-grafana .. note:: If you have pulled the pre-built barometer-influxdb and barometer-grafana images there is no requirement to complete steps outlined in sections `Build InfluxDB Docker Image`_ and `Build Grafana Docker Image`_ and you can proceed directly to section `Run the Influxdb and Grafana Images`_ Build InfluxDB docker image ^^^^^^^^^^^^^^^^^^^^^^^^^^^ Build influxdb image from Dockerfile .. code:: bash $ cd barometer/docker/barometer-influxdb $ sudo docker build -t opnfv/barometer-influxdb --build-arg http_proxy=`echo $http_proxy` \ --build-arg https_proxy=`echo $https_proxy` --network=host -f Dockerfile . .. note:: In the above mentioned ``docker build`` command, http_proxy & https_proxy arguments needs to be passed only if system is behind an HTTP or HTTPS proxy server. Check the docker images: .. code:: bash $ sudo docker images Output should contain an influxdb image: .. code:: REPOSITORY TAG IMAGE ID CREATED SIZE opnfv/barometer-influxdb latest 1e4623a59fe5 3 days ago 191MB Build Grafana docker image ^^^^^^^^^^^^^^^^^^^^^^^^^^ Build Grafana image from Dockerfile .. code:: bash $ cd barometer/docker/barometer-grafana $ sudo docker build -t opnfv/barometer-grafana --build-arg http_proxy=`echo $http_proxy` \ --build-arg https_proxy=`echo $https_proxy` -f Dockerfile . .. note:: In the above mentioned ``docker build`` command, http_proxy & https_proxy arguments needs to be passed only if system is behind an HTTP or HTTPS proxy server. Check the docker images: .. code:: bash $ sudo docker images Output should contain an influxdb image: .. code:: REPOSITORY TAG IMAGE ID CREATED SIZE opnfv/barometer-grafana latest 05f2a3edd96b 3 hours ago 1.2GB Run the Influxdb and Grafana Images ----------------------------------- Run the InfluxDB docker image ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. code:: bash $ sudo docker run -tid -v /var/lib/influxdb:/var/lib/influxdb --net=host\ --name bar-influxdb opnfv/barometer-influxdb Check your docker image is running .. code:: bash sudo docker ps To make some changes when the container is running run: .. code:: bash sudo docker exec -ti /bin/bash When both collectd and InfluxDB containers are located on the same host, then no additional configuration have to be added and you can proceed directly to `Run the Grafana docker image`_ section. Modify collectd to support InfluxDB on another host ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ If InfluxDB and collectd containers are located on separate hosts, then additional configuration have to be done in ``collectd`` container - it normally sends data using network plugin to 'localhost/127.0.0.1' therefore changing output location is required: 1. Stop and remove running bar-collectd container (if it is running) .. code:: bash $ sudo docker ps #to get collectd container name $ sudo docker rm -f 2. Go to location where shared collectd config files are stored .. code:: bash $ cd $ cd src/collectd/collectd_sample_configs 3. Edit content of ``network.conf`` file. By default this file looks like that: .. code:: LoadPlugin network Server "127.0.0.1" "25826" ``127.0.0.1`` string has to be replaced with the IP address of host where InfluxDB container is running (e.g. ``192.168.121.111``). Edit this using your favorite text editor. 4. Start again collectd container like it is described in `Run the collectd stable docker image`_ chapter .. code:: bash $ cd $ sudo docker run -ti --name bar-collectd --net=host -v \ `pwd`/src/collectd/collectd_sample_configs:/opt/collectd/etc/collectd.conf.d \ -v /var/run:/var/run -v /tmp:/tmp --privileged opnfv/barometer-collectd Now collectd container will be sending data to InfluxDB container located on remote Host pointed by IP configured in step 3. Run the Grafana docker image ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Connecting to an influxdb instance running on local system and adding own custom dashboards .. code:: bash $ cd $ sudo docker run -tid -v /var/lib/grafana:/var/lib/grafana \ -v ${PWD}/docker/barometer-grafana/dashboards:/opt/grafana/dashboards \ --name bar-grafana --net=host opnfv/barometer-grafana Connecting to an influxdb instance running on remote system with hostname of someserver and IP address of 192.168.121.111 .. code:: bash $ sudo docker run -tid -v /var/lib/grafana:/var/lib/grafana --net=host -e \ influxdb_host=someserver --add-host someserver:192.168.121.111 --name \ bar-grafana opnfv/barometer-grafana Check your docker image is running .. code:: bash sudo docker ps To make some changes when the container is running run: .. code:: bash sudo docker exec -ti /bin/bash Connect to :3000 with a browser and log into grafana: admin/admin Cleanup of influxdb/grafana configuration ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ When user wants to remove current grafana and influxdb configuration, folowing actions have to be performed 1. Stop and remove running influxdb and grafana containers .. code:: bash sudo docker rm -f bar-grafana bar-influxdb 2. Remove shared influxdb and grafana folders from the Host .. code:: bash sudo rm -rf /var/lib/grafana sudo rm -rf /var/lib/influxdb .. note:: Shared folders are storing configuration of grafana and influxdb containers. In case of changing influxdb or grafana configuration (e.g. moving influxdb to another host) it is good to perform cleanup on shared folders to not affect new setup with an old configuration. Build and Run VES and Kafka Docker Images ----------------------------------------- Download VES and Kafka docker images ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ If you wish to use pre-built barometer project's VES and kafka images, you can pull the images from https://hub.docker.com/r/opnfv/barometer-ves/ and https://hub.docker.com/r/opnfv/barometer-kafka/ .. note:: If your preference is to build images locally please see sections `Build Kafka Docker Image`_ and `Build VES Docker Image`_ .. code:: bash $ docker pull opnfv/barometer-kafka $ docker pull opnfv/barometer-ves .. note:: If you have pulled the pre-built images there is no requirement to complete steps outlined in sections `Build Kafka Docker Image`_ and `Build VES Docker Image`_ and you can proceed directly to section `Run Kafka Docker Image`_ Build Kafka docker image ^^^^^^^^^^^^^^^^^^^^^^^^ Build Kafka docker image: .. code:: bash $ cd barometer/docker/barometer-kafka $ sudo docker build -t opnfv/barometer-kafka --build-arg http_proxy=`echo $http_proxy` \ --build-arg https_proxy=`echo $https_proxy` -f Dockerfile . .. note:: In the above mentioned ``docker build`` command, http_proxy & https_proxy arguments needs to be passed only if system is behind an HTTP or HTTPS proxy server.

Zookeeper can be running locally or on a remote platform. Kafka's broker_id and address of its zookeeper instance can be configured by setting values for environmental variables 'broker_id' and 'zookeeper_node'. In instance where 'broker_id' and/or 'zookeeper_node' is not set the default setting of broker_id=0 and zookeeper_node=localhost is used. In intance where Zookeeper is running on same node as Kafka and there is a one to one relationship between Zookeeper and Kafka, default setting can be used. The docker argument `add-host` adds hostname and IP address to /etc/hosts file in container Run zookeeper docker image: .. code:: bash $ sudo docker run -tid --net=host -p 2181:2181 zookeeper:3.4.11 Run kafka docker image which connects with a zookeeper instance running on same node with a 1:1 relationship .. code:: bash $ sudo docker run -tid --net=host -p 9092:9092 opnfv/barometer-kafka Run kafka docker image which connects with a zookeeper instance running on a node with IP address of 192.168.121.111 using broker ID of 1 .. code:: bash $ sudo docker run -tid --net=host -p 9092:9092 --env broker_id=1 --env zookeeper_node=zookeeper --add-host \ zookeeper:192.168.121.111 opnfv/barometer-kafka Run VES Application docker image ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. note:: VES application uses configuration file ves_app_config.conf from directory barometer/3rd_party/collectd-ves-app/ves_app/config/ and host.yaml file from barometer/3rd_party/collectd-ves-app/ves_app/yaml/ by default. If you wish to use a custom config file it should be mounted to mount point /opt/ves/config/ves_app_config.conf. To use an alternative yaml file from folder barometer/3rd_party/collectd-ves-app/ves_app/yaml the name of the yaml file to use should be passed as an additional command. If you wish to use a custom file the file should be mounted to mount point /opt/ves/yaml/ Please see examples below Run VES docker image with default configuration .. code:: bash $ sudo docker run -tid --net=host opnfv/barometer-ves Run VES docker image with guest.yaml files from barometer/3rd_party/collectd-ves-app/ves_app/yaml/ .. code:: bash $ sudo docker run -tid --net=host opnfv/barometer-ves guest.yaml Run VES docker image with using custom config and yaml files. In example below yaml/ folder cotains file named custom.yaml .. code:: bash $ sudo docker run -tid --net=host -v ${PWD}/custom.config:/opt/ves/config/ves_app_config.conf \ -v ${PWD}/yaml/:/opt/ves/yaml/ opnfv/barometer-ves custom.yaml Run VES Test Collector application ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ VES Test Collector application can be used for displaying platform wide metrics that are collected by barometer-ves container. Setup instructions are located in: :ref:`Setup VES Test Collector` Build and Run DMA and Redis Docker Images ----------------------------------------- Download DMA docker images ^^^^^^^^^^^^^^^^^^^^^^^^^^ If you wish to use pre-built barometer project's DMA images, you can pull the images from https://hub.docker.com/r/opnfv/barometer-dma/ .. note:: If your preference is to build images locally please see sections `Build DMA Docker Image`_ .. code:: bash $ docker pull opnfv/barometer-dma .. note:: If you have pulled the pre-built images there is no requirement to complete steps outlined in sections `Build DMA Docker Image`_ and you can proceed directly to section `Run DMA Docker Image`_ Build DMA docker image ^^^^^^^^^^^^^^^^^^^^^^ Build DMA docker image: .. code:: bash $ cd barometer/docker/barometer-dma $ sudo docker build -t opnfv/barometer-dma --build-arg http_proxy=`echo $http_proxy` \ --build-arg https_proxy=`echo $https_proxy` -f Dockerfile . .. note:: In the above mentioned ``docker build`` command, http_proxy & https_proxy arguments needs to be passed only if system is behind an HTTP or HTTPS proxy server. Check the docker images: .. code:: bash $ sudo docker images Output should contain a barometer image: .. code:: REPOSITORY TAG IMAGE ID CREATED SIZE opnfv/barometer-dma latest 2f14fbdbd498 3 hours ago 941 MB Run Redis docker image ^^^^^^^^^^^^^^^^^^^^^^ .. note:: Before running DMA, Redis must be running. Run Redis docker image: .. code:: bash $ sudo docker run -tid -p 6379:6379 --name barometer-redis redis Check your docker image is running .. code:: bash sudo docker ps Run DMA docker image ^^^^^^^^^^^^^^^^^^^^ .. note:: Run DMA docker image with default configuration .. code:: bash $ cd barometer/docker/barometer-dma $ sudo mkdir /etc/barometer-dma $ sudo cp ../../src/dma/examples/config.toml /etc/barometer-dma/ $ sudo vi /etc/barometer-dma/config.toml (edit amqp_password and os_password:OpenStack admin password) $ sudo su - (When there is no key for SSH access authentication) # ssh-keygen (Press Enter until done) (Backup if necessary) # cp ~/.ssh/authorized_keys ~/.ssh/authorized_keys_org # cat ~/.ssh/authorized_keys_org ~/.ssh/id_rsa.pub \ > ~/.ssh/authorized_keys # exit $ sudo docker run -tid --net=host --name server \ -v /etc/barometer-dma:/etc/barometer-dma \ -v /root/.ssh/id_rsa:/root/.ssh/id_rsa \ -v /etc/collectd/collectd.conf.d:/etc/collectd/collectd.conf.d \ opnfv/barometer-dma /server $ sudo docker run -tid --net=host --name infofetch \ -v /etc/barometer-dma:/etc/barometer-dma \ -v /var/run/libvirt:/var/run/libvirt \ opnfv/barometer-dma /infofetch (Execute when installing the threshold evaluation binary) $ sudo docker cp infofetch:/threshold ./ $ sudo ln -s ${PWD}/threshold /usr/local/bin/ References ^^^^^^^^^^ ..
