Deploy your own Xtesting CI/CD toolchains

For the time being, the ansible playbooks automatically deploy the next components (they are configured to allow running testcases directly):

Jenkins
Minio
S3www
MongoDB
TestAPI
Docker Registry
PostgreSQL
Cachet
GitLab
InfluxDB
Grafana

Here are the default TCP ports which have to be free or updated (see https://github.com/collivier/ansible-role-xtesting/blob/master/defaults/main.yml):

Jenkins: 8080
Minio: 9000
S3www: 8181
TestAPI: 8000
Docker Registry: 5000
PostgreSQL: 5432
Cachet: 8001
GitLab: 80
InfluxDB: 8086
Grafana: 3000

Xtesting is designed to allow running your own containers based on that framework even out of the Infrastracture domain (e.g. ONAP).

Be free to list them into suites!

Add Xtesting user (Optional)

It should be noted the ansible user must be allowed to run tasks with the root privileges via sudo. NOPASSWD may be an help but you could rather prompt the password (e.g. sudo ls) before deploying the toolchains.

Create Xtesting user

sudo useradd -s /bin/bash -m xtesting
echo "xtesting ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/xtesting
sudo su - xtesting

Create a virtualenv (Optional)

It should be noted that ansible 2.9 or newer is required and that a few python packages are installed via pip. Therefore you may create a python virtualenv. It's worth mentioning that CentOS forces us to give the virtual environment access to the global site-packages (libselinux-python wouldn't be available).

Create Xtesting virtualenv (Debian Buster and Ubuntu Focal)

sudo apt update && sudo apt install virtualenv -y
virtualenv xtesting --system-site-packages
. xtesting/bin/activate
pip install ansible

Create Xtesting virtualenv (CentOS 8)

sudo yum install epel-release -y
sudo yum install virtualenv -y
virtualenv xtesting --system-site-packages
. xtesting/bin/activate
pip install ansible

Install dependencies

Xtesting Continous Integration helper only depends on ansible>=2.9. In case of Debian Buster, ansible should be installed via pip as the official Debian package is too old. It should be installed via pip in Ubuntu as well to avoid mismatches between ansible and virtualenv Ubuntu packages. It should be noted that git is only needed for the following playbooks.

Install dependencies (Debian Buster):

sudo apt update && sudo apt install git -y
[ -z "$VIRTUAL_ENV" ] && sudo apt install python-pip -y && sudo pip install ansible
ansible-galaxy install collivier.xtesting
ansible-galaxy collection install ansible.posix community.general community.grafana \
  community.kubernetes community.docker community.postgresql

Install dependencies (Ubuntu Focal):

sudo apt update && sudo apt install git -y
[ -z "$VIRTUAL_ENV" ] && sudo apt install python3-pip -y && sudo pip3 install ansible
ansible-galaxy install collivier.xtesting
ansible-galaxy collection install ansible.posix community.general community.grafana \
  community.kubernetes community.docker community.postgresql

Install dependencies (CentOS 8):

sudo yum install epel-release -y
sudo yum install git -y
[ -z "$VIRTUAL_ENV" ] && sudo yum install ansible -y
ansible-galaxy install collivier.xtesting
ansible-galaxy collection install ansible.posix community.general community.grafana \
  community.kubernetes community.docker community.postgresql

If proxy

All Xtesting CI playbooks could be executed behind a proxy and the proxy settings would be copied in docker daemon configuration files. You can set the remote environment at the play level.

Here is the configuration used in the gates

Encrypt your passwords

The default XtestingCI passwords are simple and clear text on purpose. But it must be noted that XtestingCI allows overriding any password (via encryped values or not). Here are basic instructions to encrypt XtestingCI content with Ansible Vault. Please see Encrypting content with Ansible Vault for more details

Create a password file:

echo foo > a_password_file

Encrypt a new Jenkins password (here jenkins_password):

ansible-vault encrypt_string --vault-id a_password_file jenkins_password --name jenkins_password

Copy the encrypted password in site.yml

Use verified Docker images

XtestingCI priorly selects the official images as proposed by the upstream projects. Be free to use any custom image if it fits your security best practices or any other enterprise choice. It's worth mentioning that all specific XtestingCI Docker containers are built on a daily basis and verified via Trivy to warn the endusers about any CVE known for the containerized services or for the underlying distributions.

In the same manner, XtestingCI selects an official PostgreSQL container based on Alpine. Here is a simple example picking another one based on Debian.

---
- hosts: 127.0.0.1
  roles:
    - role: collivier.xtesting
      postgres_docker_tag: 13-bullseye

The following example switches from Gitlab Community Edition to Gitlab Enterprise Edition:

---
- hosts: 127.0.0.1
  roles:
    - role: collivier.xtesting
      jenkins_deploy: false
      gitlab_deploy: true
      gitlab_docker_image: gitlab/gitlab-ee
      gitlab_docker_tag: 13.12.11-ee.0

Tune your Continuous Integration toolchain

XtestingCI supports multiple deployment models such as all-in-one (in Docker or in Kubernetes), centralized services (e.g. OPNFV toolchain) or a mix of both.

It follows the KISS principle, by spliting all deployment and configuration steps and by leveraging urls for any configuration action. The same operations can be applied whatever the services are deployed via Docker, via Kubernetes or via any other way out of XtestingCI.

XtestingCI defines lots of variables to finely select the services (Jenkins vs GitLab, Minio vs Ceph radosgw, etc.) or the steps you want to execute. For instance, jenkins_deploy decides if you install Jenkins or not, jenkins_configure (in addition to jenkins_url) if you configure it. The same model is generalized for all the services.

The default configuration setups the following services in a single host but you're free to change it at your convenience; it's just about setting booleans and urls:

Jenkins
MongoDB
TestAPI
Minio
PostgreSQL
Cachet

Please see the following Katacoda training courses which quickly highlight a few distributed scenarios:

Note: Kubernetes allows defining Pod Security Policies in case the priviledged test cases must be forbidden.
