problem with docker repo & docker-ce-cli installation

[Jan Henrik Schlüter]

The V23 binariers were added to https://download.docker.com/linux/centos/7/x86_64/stable/Packages/ on 2.2.2023 which now causes problems when running docker-ce-* installations due package manager picking latest release V23 instead of V20.10.:

• name: Install docker-ce-cli {{ __docker_version }}
  package:
  name: docker-ce-cli-{{ __docker_version }}
  state: present
  allow_downgrade: yes
  when:
  • ansible_os_family == "RedHat"

Leads into

I still do not understand how the dockerx plugin is installed using the playbooks. I could only find refrences to "docker-ce" & "docker-ce-cli" in "install_docker_centos_redhat.yml"

Docker install scripts are not maintained as Kubernetes deprecated Docker as a container runtime after v1.20.

Docker images for the component pack deployment are stored in the HCL Harbor repository and containerd is used as CRI runtime. Click here for more details on how to setup component pack for HCL Connections.
