Atlassian Bamboo agent Python3 role

Installs python3 from an installer or Debian packages into a remote machine and declares the python3 as a Bamboo system command capability.

Requirements

This role does not have any particular requirement, except that the installers need to be available for Windows and OSX (no brew or chocolatey involved, no Internet connexion needed). On Ubuntu, it relies on the OS packaging system, so an Internet connexion is required.

Role Variables

variable	default	meaning
python3_version	required	the exact version of python3
python3_installer	required	the installer file (OSX, Windows)
bamboo_capabilities	(empty dict)	capabilities that will be populated by the role.
windows_python3_installation_folder	C:\Python37	Installation folder for Windows.

Capabilities declared by the role

capability	value
system.builder.command.python${version.major}.${version.minor}	location of the python3 binary of the given major/minor version

Variables and tags

• Ubuntu: apt-get install is used on this platform, with the version major and minor coming from the python3_version variable. After the installation python3 location is taken from /usr/bin/
• OSX: the provided installer from the variable python3_installer is used. This currently should be a .pkg file, python3 location is looked for using the which python3 shell command.

The tags in use by the role are:

• capability: task filling a capability
• python3: all tasks of the role
• installation: task installing new software

Example Playbook

• In the inventory file for the osx group, we can have configure the python3 install like the following

  bamboo_python3_version:
    major: 3
    minor: 4
    patch: 3
  
  bamboo_python3_installer:
    file: "/path/to/installer-pkg/python-{{bamboo_python3_version.major}}.{{bamboo_python3_version.minor}}.{{bamboo_python3_version.patch}}-macosx10.6.pkg"

• In the inventory for linux group, we can just have this:

  bamboo_python3_version:
    major: 3
    minor: 4
    patch: 3

  although we will not be ensured that the patch part will be honoured properly by apt-get

• then the playbook can be writen like this:

  - hosts: all-bamboo-agents
  
    vars:
      - osfile_location: "{% if ansible_distribution=='MacOSX' %}osx{% elif ansible_distribution=='Ubuntu' %}linux{% elif ansible_os_family=='Windows' %}windows{% endif %}"
  
    pre_tasks:
      - name: Reading the agent capability file
        include_role:
          name: atlassian-bambooagent-role
          tasks_from: read_capability
  
    roles:
      # Adding python3 role to the agent
      - role: bamboo-agent-python3
        python3_version: "{{ bamboo_python3_version }}"
        python3_installer: "{{ bamboo_python3_installer }}"
  
    post_tasks:
      - name: Updating the agent capability file
        include_role:
          name: atlassian-bambooagent-role
          tasks_from: write_capability
