How do I make Ansible ignore failed tarball extraction?

I have a command in an ansible playbook:

- name: extract the tarball
  command: tar --ignore-command-error -xvkf release.tar

It is expected that some files won't be extracted as they exist already (-k flag).

However, this results in ansible stopping the overall playbook as there is an error code from the tar extraction.

How can I work around this? As you can see I have tried --ignore-command-error to no avail.

You want to use the ignore_errors argument:

- name: extract the tarball
  command: tar --ignore-command-error -xvkf release.tar
  ignore_errors: yes

See "Ignore Failed Commands" in the Error Handling documentation page.

ignore_errors works best when you can detect success in some manner- you can register the output and check that, or you can use creates to look for a specific filename.

ignore_errors: yes will still raise an error showing the failed task on the prompt. If you want that task to fail silently, you can set failed_when: false or more sophisticated condition like described in the manual:

- name: this command prints FAILED when it fails
  command: /usr/bin/example-command -x -y -z
  register: command_result
  failed_when: "'FAILED' in command_result.stderr"

So you could search the output of stderr. You maybe still want to fail if the file is not readable, not exists or whatever, but not fail when the archive is broken and can't be extracted.
