+
+Barometer docker image 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.
+
+The intention of this user guide is to outline how to install and test the
+barometer docker image that can be built from the Dockerfile available in the
+barometer repository.
+
+.. note::
+ The Dockerfile is available in the docker/ directory in the barometer repo.
+ The Dockerfile builds a CentOS 7 docker image.
+
+The barometer docker image gives you a collectd installation that includes all
+the barometer plugins.
+
+.. note::
+ 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.
+
+Barometer 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
+
+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
+
+
+Installing Docker
+-----------------
+.. Describe the specific capabilities and usage for <XYZ> feature.
+.. Provide enough information that a user will be able to operate the feature on a deployed scenario.
+
+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 <username>
+ $ sudo systemctl status docker
+
+Replace <username> 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 <username>
+ $ sudo systemctl status docker
+
+Replace <username> 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) <docker@docker.com>"
+ 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
+
+Proxy Configuration:
+^^^^^^^^^^^^^^^^^^^^
+.. 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
+
+ Unable to find image 'hello-world:latest' locally
+ latest: Pulling from library/hello-world
+ 5b0f327be733: Pull complete
+ Digest: sha256:07d5f7800dfe37b8c2196c7b1c524c33808ce2e0f74e7aa00e603295ca9a0972
+ Status: Downloaded newer image for hello-world:latest
+
+ 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:
+
+.. code:: bash
+
+ $ docker run -it ubuntu bash
+
+Build the barometer docker image
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code:: bash
+
+ $ cd barometer
+ $ sudo docker build -t barometer_image --build-arg http_proxy=`echo $http_proxy` \
+ --build-arg https_proxy=`echo $https_proxy` -f docker/Dockerfile .
+
+Check the docker images:
+
+.. code:: bash
+
+ $ sudo docker images
+
+Output should contain a barometer image:
+
+.. code::
+
+ REPOSITORY TAG IMAGE ID CREATED SIZE
+ barometer_image 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
+
+Run the barometer docker image:
+
+.. code:: bash
+
+ $ sudo docker run -tid --net=host -v `pwd`/../src/collectd_sample_configs:/opt/collectd/etc/collectd.conf.d \
+ -v /var/run:/var/run -v /tmp:/tmp --privileged barometer_image /run_collectd.sh
+
+.. note::
+ The docker barometer 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
+ `pwd`/../src/collectd_sample_configs thta contains only the sample configurations we are interested
+ in running.
+
+To make some changes run:
+
+.. code:: bash
+
+ sudo docker exec -tid barometer_image /bin/bash
+
+Check your docker image is running
+
+.. code:: bash
+
+ sudo docker ps
+
+Build the influxdb + Grafana docker images
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Start by installing docker compose:
+
+.. code:: bash
+
+ $ sudo curl -L https://github.com/docker/compose/releases/download/1.17.0/docker-compose-`uname -s`-`uname -m` -o /usr/bin/docker-compose
+
+.. note::
+ Use the latest Compose release number in the download command. The above command is an example,
+ and it may become out-of-date. To ensure you have the latest version, check the Compose repository
+ release page on GitHub.
+
+2. Apply executable permissions to the binary:
+
+.. code:: bash
+
+ $ sudo chmod +x /usr/bin/docker-compose
+
+3. Test the installation.
+
+.. code:: bash
+
+ $ sudo docker-compose --version
+
+4. Run the get_types_db.sh script in barometer/docker
+
+5. Run the docker containers:
+
+.. code:: bash
+
+ $ sudo docker-compose up -d
+
+6. Check your docker images are running
+
+.. code:: bash
+
+ $ sudo docker ps
+
+7. Run the script to create the CPU dashboard barometer/docker:
+
+.. code:: bash
+
+ $ ./configure_grafana.sh
+
+8. Connect to <host_ip>:3000 with a browser and log into grafana: admin/admin
+
