New Ansible version needs to be available
In the repository of this image, the newest available version of Ansible is 2.7.7. For some applications, 2.9 is needed. There are two possible solutions.
- Add the PPA of Ansible to the image (from the installation guide).
- Install Ansible 2.9 directly.
It requires testing which method is better. We need to consider the difference between the sizes of images and building time.
