Preparing the Docker container
------------------------------
-Pull the Functest Docker image from the Docker hub::
+Pull the Functest Docker image ('opnfv/functest') from the public dockerhub
+registry under the OPNFV account: [dockerhub_], with the following docker
+command::
- docker pull opnfv/functest:brahmaputra.1.0
+ docker pull opnfv/functest:<TagIdentifier>
+where <TagIdentifier> identifies a specifically tagged release of the Functest
+docker container image in the public dockerhub registry. There are many
+different tags created automatically by the CI mechanisms, but you must ensure
+you pull an image with the **correct tag** to match the OPNFV software release
+installed in your environment. All available tagged images can be seen from
+location [FunctestDockerTags_]. For example, when running on the first official
+release of the OPNFV Colorado system platform, tag "colorado.1.0" is needed.
+Pulling other tags might cause some problems while running the tests. If you
+need to specifically pull the latest Functest docker image, then omit the tag
+argument::
-Check that the image is available::
- docker images
+ docker pull opnfv/functest
-Run the docker container giving the environment variables:
+After pulling the Docker image, check that the pulled image is available with
+the following docker command::
- * **INSTALLER_TYPE** : possible values are **apex**, **compass**, **fuel** or **joid**.
- * **INSTALLER_IP** : IP of the installer node/VM.
-
-Functest may need to know the IP of the installer to retrieve automatically the
-credentials from the installer node/VM or even from the actual controllers.
-
-The minimum command to create the Functest Docker container can be described as
-follows::
+ [functester@jumphost ~]$ docker images
- docker run -it -e "INSTALLER_IP=10.20.0.2" -e "INSTALLER_TYPE=fuel" opnfv/functest:brahmaputra.1.0 /bin/bash
+ REPOSITORY TAG IMAGE ID CREATED SIZE
+ opnfv/functest latest 8cd6683c32ae 2 weeks ago 1.611 GB
+ opnfv/functest brahmaputra.3.0 94b78faa94f7 4 weeks ago 874.9 MB
+ hello-world latest 94df4f0ce8a4 7 weeks ago 967 B
-Optionally, it is possible to precise the container name through the option
-**--name**::
+ (Docker images pulled without a tag specifier bear the implicitly
+ assigned label "latest", as seen above.)
- docker run --name "CONTAINER_NAME" -it -e "INSTALLER_IP=10.20.0.2" -e "INSTALLER_TYPE=fuel" opnfv/functest:brahmaputra.1.0 /bin/bash
+The Functest docker container environment can -in principle- be also used with
+non-OPNFV official installers (e.g. 'devstack), with the **disclaimer** that
+support for such environments is outside of the scope of responsibility of the
+OPNFV project.
-It is also possible to to indicate the path of the OpenStack credentials using **-v**::
+The minimum command to create the Functest Docker container can be described as
+follows::
- docker run -it -e "INSTALLER_IP=10.20.0.2" -e "INSTALLER_TYPE=fuel" -v <path_to_your_local_creds_file>:/home/opnfv/functest/conf/openstack.creds opnfv/functest:brahmaputra.1.0 /bin/bash
+ docker run -it opnfv/functest:<TagIdentifier> /bin/bash
-The local file will be mounted in the container under
-*/home/opnfv/functest/conf/openstack.creds*
+For OPNFV official installers, it is recommended (although no longer mandatory)
+to provide two additional environment variables, in the 'docker run ...'
+command nvocation:
-If the intention is to run Functest against any of the supported OPNFV scenarios,
-it is recommended to include also the environment variable **DEPLOY_SCENARIO**,
-for example::
+ * **INSTALLER_TYPE** : possible values are **apex**, **compass**, **fuel** or
+ **joid**.
+ * **INSTALLER_IP** : IP of the installer node/VM.
- docker run -it -e "INSTALLER_IP=10.20.0.2" -e "INSTALLER_TYPE=fuel" -e "DEPLOY_SCENARIO=os-odl_l2-nofeature-ha" opnfv/functest:brahmaputra.1.0 /bin/bash
+Functest may need to know the IP of the installer to retrieve automatically the
+credentials from the installer node/VM or even from the actual controllers.
-Inside the container, the following directory structure should be in place::
+Thus, the recommended minimum command to create the Functest Docker container
+for OPNFV installer can be described (using installer 'fuel', and an invented
+INSTALLER_IP of '10.20.0.2', for example), as follows::
+
+ docker run -it \
+ -e "INSTALLER_IP=10.20.0.2" \
+ -e "INSTALLER_TYPE=fuel" \
+ opnfv/functest:<TagIdentifier> /bin/bash
+
+Optionally, it is possible to assign precisely a container name through the
+**--name** option::
+
+ docker run --name "CONTAINER_NAME" -it \
+ -e "INSTALLER_IP=10.20.0.2" \
+ -e "INSTALLER_TYPE=fuel" \
+ opnfv/functest:<TagIdentifier> /bin/bash
+
+It is also possible to to indicate the path of the OpenStack credentials using a
+**-v** option::
+
+ docker run -it \
+ -e "INSTALLER_IP=10.20.0.2" \
+ -e "INSTALLER_TYPE=fuel" \
+ -v <path_to_your_local_creds_file>:/home/opnfv/functest/conf/openstack.creds \
+ opnfv/functest:<TagIdentifier> /bin/bash
+
+ NOTE: Make sure you have placed the needed credential file into the
+ Jumphost local path <path_to_your_local_cred_file>. For the
+ Apex Installer you will need to pre-copy the required OpenStack
+ credentials file from the Instack/Undercloud Virtual Machine.
+ See the section 'Apex Installer Tips' later in this document.
+
+ Warning
+ -------
+ If you are using the Joid installer, you must use the method above
+ to provide the required OpenStack credentials. See the section
+ 'Focus on the OpenStack credentials' later in this document.
+
+
+The local openstack credential file will be mounted in the Docker container
+under the path: '/home/opnfv/functest/conf/openstack.creds'
+
+If the intention is to run Functest against any of the supported OPNFV
+scenarios, it is recommended to include also the environment variable
+**DEPLOY_SCENARIO**. The **DEPLOY_SCENARIO** environment variable is passed with the format::
+
+ -e "DEPLOY_SCENARIO=os-<controller>-<nfv_feature>-<ha_mode>"
+
+ where:
+ os = OpenStack (No other VIM choices currently available)
+ controller is one of ( nosdn | odl_l2 | odl_l3 | onos | ocl )
+ nfv_feature is one or more of ( ovs | kvm | sfc | bgpvpn | nofeature )
+ If several features are pertinent then use the underscore
+ character '_' to separate each feature (e.g. ovs_kvm)
+ 'nofeature' indicates no NFV feature is deployed
+ ha_mode is one of ( ha | noha )
+
+For example::
+
+ docker run -it \
+ -e "INSTALLER_IP=10.20.0.2" \
+ -e "INSTALLER_TYPE=fuel" \
+ -e "DEPLOY_SCENARIO=os-odl_l2-ovs_kvm-ha" \
+ opnfv/functest:<TagIdentifier> /bin/bash
+
+**NOTE:** Not all possible combinations of "DEPLOY_SCENARIO" are supported.
+The scenario name passed in to the Functest Docker container must match the
+scenario used with the selected installer to create the actual OPNFV platform
+deployment.
+
+Finally, three additional environment variables can also be passed in to the
+Functest Docker Container, using the -e "<EnvironmentVariableName>=<Value>"
+mechanism. The first two of these are only relevant to Jenkins CI invoked
+testing and **should not be used** when performing manual test scenarios::
+
+ -e "NODE_NAME=<Test POD Name>" \
+ -e "BUILD_TAG=<Jenkins Build Tag>" \
+ -e "CI_DEBUG=<DebugTraceValue>"
+
+ where:
+ <Test POD Name> = Symbolic name of the POD where the tests are run.
+ Visible in test results files, which are stored
+ to the database. This option is only used when
+ tests are activated under Jenkins CI control.
+ It indicates the POD/hardware where the test has
+ been run. If not specified, then the POD name is
+ defined as "Unknown" by default.
+ DO NOT USE THIS OPTION IN MANUAL TEST SCENARIOS.
+
+ <Jenkins Build tag> = Symbolic name of the Jenkins Build Job.
+ Visible in test results files, which are stored
+ to the database. This option is only set when
+ tests are activated under Jenkins CI control.
+ It enables the correlation of test results, which
+ are independently pushed to the results datbase
+ from different Jenkins jobs.
+ DO NOT USE THIS OPTION IN MANUAL TEST SCENARIOS.
+
+ <DebugTraceValue> = "true" or "false"
+ Default = "false", if not specified
+ If "true" is specified, then additional debug trace
+ text can be sent to the test results file / log files
+ and also to the standard console output.
+
+Apex Installer Tips
+-------------------
+Some specific tips are useful for the Apex Installer case. If not using Apex
+Installer; ignore this section.
+
+ #. The "INSTALLER_IP" environment variable should be set equal to the IP
+ address of the so-called "Instack/undercloud Virtual Machine".
+
+ In the Jumphost, execute the following command and note the returned
+ IP address::
+
+ sudo virsh domifaddr undercloud | grep -Eo "[0-9.]+{4}"
+
+ NOTE: In releases prior to Colorado, the name 'instack' was
+ used. From Colorado onward, the name 'undercloud' is used.
+ If in doubt, then execute -from the Jumphost- the command
+ "virsh list" to see which name is in use for the Installer
+ Virtual Machine.
+
+ You can now enter the <Specific IP Address> as learned in the above step in the
+ -e option specification::
+
+ -e "INSTALLER_IP=<Specific IP Address>"
+
+ #. If you want to 'Bind mount' a local Openstack credentials file ("overcloudrc")
+ to the Docker container, then you may need to first pre-copy that file from the
+ 'Instack/Undercloud VM' to the Jump host.
+
+ As before, in the Jumphost, execute the following command and note the
+ returned IP address::
+
+ sudo virsh domifaddr undercloud | grep -Eo "[0-9.]+{4}"
+
+ Using the <Specific IP Address> just learned above, execute the following
+ shell commands **in the Jumphost**, before issuing the 'docker run ...' command
+ invocation::
+
+ scp stack@<Specific IP Address>:overcloudrc .
+ sed -i 's/export no_proxy/#export no_proxy/' overcloudrc
+ # The above 'sed' command is needed *only* in cases where
+ # the Jumphost is operating behind a http proxy.
+ # See the 'Proxy Support' section later on in this document
+
+ NOTE: There are two Openstack credential files present in the
+ Instack/Undercloud VM: 'overcloudrc' and 'stackrc'.
+ Don't mix these up! The file 'stackrc' is intended for use with
+ 'Triple O Undercloud'; only. The SUT always requires OpenStack
+ Overcloud Credentials.
+
+ The file located at Jumphost path: '~/overcloudrc' is now 'Bind mounted'
+ to the Docker path '/home/opnfv/functest/conf/openstack.creds'
+ by specifying a **-v** option::
+
+ -v ~/overcloudrc:/home/opnfv/functest/conf/openstack.creds
+
+ in the argument list of the 'docker run ...' command invocation. In the
+ Apex installer case, the Openstack Credential file has the name
+ 'overcloudrc' and is located in the home directory of the 'stack' user
+ ( '/home/stack/' or '~/'] ) in the 'Instack/Undercloud VM'.
+
+ #. In order that the docker container can access the Instack/Undercloud VM,
+ even with 'stack' user, the SSH keys of the Jumphost root user **must be**
+ 'Bind mounted' to the docker container by the following **-v** option in
+ the 'docker run ...' command invocation::
+
+ -v /root/.ssh/id_rsa:/root/.ssh/id_rsa
+
+ #. Here is an example of the docker command invocation for an Apex installed
+ system, using latest Funtest docker container, for illustration purposes::
+
+ docker run -it --name "ApexFuncTstODL" \
+ -e "INSTALLER_IP=<Specific IP Address>" \
+ -e "INSTALLER_TYPE=apex" \
+ -e "DEPLOY_SCENARIO=os-odl_l2-nofeature-ha" \
+ -v /root/.ssh/id_rsa:/root/.ssh/id_rsa \
+ -v ~/overcloudrc:/home/opnfv/functest/conf/openstack.creds \
+ opnfv/functest /bin/bash

Preparing the Functest environment
----------------------------------
-
-Once the docker container is up and running, execute the following command in the
-prompt::
-
- ${repos_dir}/functest/docker/prepare_env.sh
-
-NOTE: **${repos_dir}** is a default environment variable inside the docker
-container, which points to */home/opnfv/repos/*
-
-This script will make sure that the requirements to run the tests are met and will
-install the needed libraries and tools by all Functest test cases. It must be run
-only once every time the docker is started from sratch.
-
+Once the Functest docker container is up and running, the required Functest
+environment needs to be prepared. A custom built **functest** CLI utility is
+availabe to perform the needed environment preparation action. Once the
+enviroment is prepared, the **functest** CLI utility can be used to run
+different functional tests. The usage of the **functest** CLI utility to run
+tests is described further in the Functest User Guide `OPNFV_FuncTestUserGuide`_
+
+Prior to commencing the Functest environment preparation, we can check the
+initial status of the environment. Issue the **functest env status** command at
+the prompt::
+
+ functest env status
+ Functest environment is not installed.
+
+ Note: When the Funtest environment is prepared, the command will
+ return the status: "Functest environment ready to run tests."
+
+To prepare the Functest docker container for test case execution, issue the
+**functest env prepare** command at the prompt::
+
+ functest env prepare
+
+This script will make sure that the requirements to run the tests are met and
+will install the needed libraries and tools by all Functest test cases. It
+should be run only once every time the Functest docker container is started
+from scratch. If you try to run this command, on an already prepared
+enviroment, you will be prompted whether you really want to continue or not::
+
+ functest env prepare
+ It seems that the environment has been already prepared.
+ Do you want to do it again? [y|n]
+
+ (Type 'n' to abort the request, or 'y' to repeat the
+ environment preparation)
+
+
+To list some basic information about an already prepared Functest docker
+container environment, issue the **functest env show** at the prompt::
+
+ functest env show

Focus on the OpenStack credentials
----------------------------------
-
The OpenStack credentials are needed to run the tests against the VIM.
There are 3 ways to provide them to Functest:
* using the -v option when running the Docker container
- * create an empty file in /home/opnfv/functest/conf/openstack.creds and paste
- the credentials in it.
+ * create an empty file in '/home/opnfv/functest/conf/openstack.creds' and
+ paste the credentials into it. (Consult your installer guide to know from
+ where you can retrieve credential files, which are set-up in the Openstack
+ installation of the SUT)
* automatically retrieved using the following script::
- $repos_dir/releng/utils/fetch_os_creds.sh
-Once the credentials are there, they shall be sourced before running the tests::
-

SSL Support
-----------
+If you need to connect to a server that is TLS-enabled (the auth URL begins
+with ‘https’) and it uses a certificate from a private CA or a self-signed
+certificate, then you will need to specify the path to an appropriate CA
+certificate to use, to validate the server certificate with the environment
+variable OS_CACERT::

-
- echo $OS_CACERT
- /etc/ssl/certs/ca.crt
-
-However, this certificate does not exist in the container by default. It has to
-be copied manually from the OpenStack deployment. This can be done in 2 ways:
+ echo $OS_CACERT
+ /etc/ssl/certs/ca.crt
- #. Create manually that file and copy the contents from the OpenStack controller.
+However, this certificate does not exist in the container by default. It has

+ #. (Recommended) Add the file using a Docker volume when starting the

+ -v <path_to_your_cert_file>:/etc/ssl/certs/ca.cert
You might need to export OS_CACERT environment variable inside the container::
- export OS_CACERT=/etc/ssl/certs/ca.crt
-
-
-Certificate verification can be turned off using OS_INSECURE=true.
-For example, Fuel uses self-signed cacerts by default, so an pre step would be::
-
- export OS_INSECURE=true
-
-
-Additional Options
-------------------
+ export OS_CACERT=/etc/ssl/certs/ca.crt
-In case you need to provide different configuration parameters to Functest (e.g.
-commit IDs or branches for the repositories, ...) copy the **config_functest.yaml**
-from the repository to your current directory and run the container with a volume::
-
- wget https://git.opnfv.org/cgit/functest/plain/testcases/config_functest.yaml
-
- <modify the file accordingly>
-
- docker run -ti -e \
- "INSTALLER_TYPE=fuel" -e "INSTALLER_IP=10.20.0.2" \
- opnfv/functest:brahmaputra.1.0 \
- -v $(pwd)/config_functest.yaml:/home/opnfv/repos/functest/ci/config_functest.yaml \
- /bin/bash\
-
-However, this is not recommended since most of the test cases rely on static
-parameters read from this file, and changing them might cause problems.
+Certificate verification can be turned off using OS_INSECURE=true. For example,
+Fuel uses self-signed cacerts by default, so an pre step would be::
+ export OS_INSECURE=true
Proxy support
-------------
+If your Jumphost node is operating behind a http proxy, then there are 2 places
+where some special actions may be needed to make operations succeed:
+
+ #. Initial installation of docker engine First, try following the official
+ Docker documentation for Proxy_ settings. Some issues were experienced on
+ CentOS 7 based Jumphost. Some tips are documented in section:
+ `Docker Installation on CentOS 7 behind http proxy`_ below.
+
+ #. Execution of the Functest environment preparation inside the created
+ docker container Functest needs internet access to download some resources
+ for some test cases. For example to install the Rally environment. This might
+ not work properly if the Jumphost is running through a http Proxy.
+
+If that is the case, make sure the resolv.conf and the needed http_proxy and
+https_proxy environment variables, as well as the 'no_proxy' environment
+variable are set correctly::
+
+ # Make double sure that the 'no_proxy=...' line in the
+ # 'openstack.creds' file is commented out first. Otherwise, the
+ # values set into the 'no_proxy' environment variable below will
+ # be ovewrwritten, each time the command
+ # 'source ~/functest/conf/openstack.creds' is issued.
+
+ sed -i 's/export no_proxy/#export no_proxy/' \
+ ~/functest/conf/openstack.creds
+
+ source ~/functest/conf/openstack.creds
+
+ # Next calculate some IP addresses for which http_proxy
+ # usage should be excluded:
+
+ publicURL_IP=$(echo $OS_AUTH_URL| \
+ grep -Eo "([0-9]+\.){3}[0-9]+")
+
+ adminURL_IP=$(openstack catalog show identity | \
+ grep adminURL | grep -Eo "([0-9]+\.){3}[0-9]+")
+
+ export http_proxy="<your http proxy settings>"
+ export https_proxy="<your httpsproxy settings>"
+ export no_proxy="127.0.0.1,localhost,$publicURL_IP,$adminURL_IP"
+
+ # Ensure that "git" uses the http_proxy
+ # This may be needed if your firewall forbids SSL based git fetch
+ git config --global http.sslVerify True
+ git config --global http.proxy <Your http proxy settings>
+
+Validation check: Before running **'functest env prepare'** CLI command,
+make sure you can reach http and https sites from inside the Functest docker
+container.
+
+For example, try to use the **nc** command from inside the functest docker
+container::
+
+ nc -v google.com 80
+ Connection to google.com 80 port [tcp/http] succeeded!
+
+ nc -v google.com 443
+ Connection to google.com 443 port [tcp/https] succeeded!
+
+Note: In a Jumphost node based on the CentOS 7, enviroment, it was observed that
+the **nc** commands did not function as described in the section above. You can
+however try using the **curl** command instead, if you encounter any issues
+with the **nc** command::
+
+ curl http://www.google.com:80
+
+ <HTML><HEAD><meta http-equiv="content-type"
+ content="text/html;charset=utf-8">
+ <TITLE>302 Moved</TITLE>
+ </HEAD>
+ <BODY>
+ <H1>302 Moved</H1>
+ :
+ :
+ </BODY></HTML>
+
+ curl https://www.google.com:443
+
+ <HTML><HEAD><meta http-equiv="content-type"
+ content="text/html;charset=utf-8">
+ <TITLE>302 Moved</TITLE>
+ </HEAD>
+ <BODY>
+ <H1>302 Moved</H1>
+ :
+ :
+ </BODY></HTML>
+
+ (Even Google complained the URL used, it proves the http and https
+ protocols are working correctly through the http / https proxy.)
+
+Docker Installation on CentOS 7 behind http proxy
+-------------------------------------------------
+There are good instructions in [`InstallDockerCentOS7`_] for the installation
+of **docker** on CentOS 7. However, if your Jumphost is behind a http proxy,
+then the following steps are needed **before** following the instructions in
+the above reference::
+
+ 1) # Make a directory '/etc/systemd/system/docker.service.d'
+ # if it does not exist
+ sudo mkdir /etc/systemd/system/docker.service.d
+
+ # Create a file called 'env.conf' in that directory with
+ # the following contents:
+ [Service]
+ EnvironmentFile=-/etc/sysconfig/docker
+
+ 2) # Set up a file called 'docker' in directory '/etc/sysconfig'
+ # with the following contents:
+
+ HTTP_PROXY="<Your http proxy settings>"
+ HTTPS_PROXY="<Your https proxy settings>"
+ http_proxy="${HTTP_PROXY}"
+ https_proxy="${HTTPS_PROXY}"
+
+ 3) # Reload the daemon
+ systemctl daemon-reload
+
+ 4) # Sanity check - check the following docker settings:
+ systemctl show docker | grep -i env
-Functest needs internet access to download some resources for some test cases.
-For example to install the Rally environment. This might not work properly if
-the Jumphost is running through a Proxy.
-
-If that is the case, make sure the resolv.conf and the needed proxy environment
-variables are properly set::
-
- export http_proxy=<your http proxy settings>
- export https_proxy=<your https proxy settings>
-
-Or refer to the official Docker documentation for Proxy_ settings.
-
-Before running **prepare_env.sh** make sure you can ping http and https sites
-inside the container. For example::
-
- nc -v google.com 80
- Connection to google.com 80 port [tcp/http] succeeded!
-
- nc -v google.com 443
- Connection to google.com 443 port [tcp/https] succeeded!
-
+ Expected result:
+ ----------------
+ EnvironmentFile=/etc/sysconfig/docker (ignore_errors=yes)
+ DropInPaths=/etc/systemd/system/docker.service.d/env.conf
+Now follow the instructions in [`InstallDockerCentOS7`_] to download and
+install the **docker-engine**. The instructions conclude with a "test pull"
+of a sample "Hello World" docker container. This should now work with the
+above pre-requisite actions.
