Unable to pull an image?

[wdrury-uk]

Hi,

Used Ansible for years but new to containers.podman.

At work, we use Artifactory for our image repos and I have proven on a RHEL 7.9 host the following:

• Successfully login Artifactory with Podman via cmdline
• Successfully pull image from Artifactory repo with Podman via cmdline
• Successfully run image from Artifactory repo with Podman via cmdline

However, when I use the containers.podman collection to mirror the steps the following step fails with syntax error occurring in one of the underlying Python code files. Does the collection have a dependency not mention in the docs?

• Successfully login Artifactory with container.podman.podman_login
• Failure with Syntax Error with container.podman.podman_image and with below code:

  - name: pull XXXYYYZZZ image
    containers.podman.podman_image:
      name: artifactory.company.co.uk/app-repo-prod/xxxyyyzzz:10.0.1
      tls_verify: no

Syntax Error

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: SyntaxError: invalid syntax

python2.7 ?
please install Python 3 to use this collection.
You can install it with yum install python3

Thanks for the response.

However, on checking the RHEL 7.9 host and the ansible.cfg its showing as using Python 3.9.5
Therefore why is the collection using Python 2.7 ?

ansible-playbook [core 2.15.2]
  config file = /mnt/c/gitrepos/github/cicd-delegate-ansible/ansible.cfg
  configured module search path = ['/home/wayne/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python3.9/dist-packages/ansible
  ansible collection location = /home/wayne/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/local/bin/ansible-playbook
  python version = 3.9.5 (default, Nov 23 2021, 15:27:38) [GCC 9.3.0] (/usr/bin/python3)
  jinja version = 3.1.2
  libyaml = True

You need to check the host where actual podman is running - lnx01, not the controller host.
To be sure Ansible uses the Python 3, you can add -e ansible_python_interpreter=/usr/bin/python3 to the Ansible command line

Sorted thank you for the assistance.

1. Required to install Python3 on RHEL7.9 as per RHEL KB --> https://access.redhat.com/solutions/4321271
2. Added ansible_python_interpreter: /usr/bin/python3 to vars: block in the main.yml playbook
