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 + + #.

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.
