Expand description

Step that installs Docker on a remote host via Ansible

Implementations§

Source§

impl InstallDockerStep

Source

pub fn new(ansible_client: Arc<AnsibleClient>) -> Self

Source

pub fn execute( &self, listener: Option<&dyn CommandProgressListener>, ) -> Result<(), CommandError>

Execute the Docker installation step

This will run the “install-docker” Ansible playbook to install Docker on the remote host. The playbook handles cache updates and Docker installation.

§Arguments
  • listener - Optional progress listener for reporting step-level details. When provided, reports debug information (Ansible commands, working directory) and detail information (installation status, Docker version).
§Errors

Returns an error if:

  • The Ansible client fails to execute the playbook
  • Docker installation fails
  • The playbook execution fails for any other reason
§Notes
  • The install-docker playbook assumes the apt cache is already updated or will handle stale cache gracefully
  • We skip the update-apt-cache playbook in E2E tests to avoid CI network issues
