Selenoid with Systemd and Ansible

Before You Begin

Selenoid does not automatically download Docker images. This playbook is designed to do that. You'll need to install the docker-py python package before you run the playbook, as I cannot assume how you're managing your Python packages. For more details on managing Docker images, check out the docker_image ansible module documentation.

How to Install It?

You can install this role using ansible-galaxy:

ansible-galaxy install -c vv-p.selenoid-systemd -p ./

Alternatively, you can download it via git:

git clone https://github.com/vv-p/selenoid-systemd.git

How to Use It?

Create your own playbook file, check the environment variables in defaults/main.yml, and run the following commands:

cat > selenoid.yml << EOF
---
- hosts: selenoid

  roles:
    - selenoid-systemd
EOF
ansible-playbook -b -i hosts selenoid.yml

Variables

Default variable values are stored in the defaults/main.yml file:

selenoid_ui: false
selenoid_vnc: false
selenoid_shmSize: 268435456
selenoid_tmpSize: 512m
selenoid_varSize: 128m
selenoid_timezone: "Europe/Moscow"
selenoid_port: 4444
selenoid_ui_port: 8080
selenoid_browsers:
  - name: "chrome"

    versions:
      - "66.0"
      - "65.0"
  - name: "firefox"

For more information, check the official documentation here: Selenoid Documentation.

You can override these values in your playbook file like this:

- hosts: all
  vars:
    selenoid_ui: true
    selenoid_vnc: true
      - name: "chrome"
        default: "66.0"
        versions:
          - "66.0"
          - "65.0"

  roles:
    - selenoid-systemd

Or you can pass them as command-line arguments:

ansible-playbook -b -i hosts selenoid.yml --extra-vars "selenoid_vnc=true"

Check the Ansible documentation for more details.
