Release 20.04 (2020-10-21)

Main topics: dockerize ansible, docker role

Added

• roles/sshd: Implemented sshd config option for sshd servers which need to
  be compatible to very old ssh clients (php 5.4 monitor01.app.infra >
  data01.xres…)
• gitclient: started role development
• docker: implemented docker host setup with docker-compose from pip
• ansible, ansible-inventory, ansible-playbook alias scripts on
  ansible.cs server
• new: ansible-docker: wrapper for user-specific misc/bin/docker-launcher
  location
• new: misc/bin/docker-launcher handler for docker specific tasks (build,
  start, stop) and launcher for ansible commands

Changes

• ansible: removed “concepts”, contents moved to roles and README files
• Mitogen strategy handler installed, replaces old “linear” which has been 5x
  slower
• Ansible update to v2.9, new: “combine” filter capability
• Ansible now runs from within docker, adapted configs and set up user
  interface (see misc/bin and misc/docker)
• SSH timeout has been raised to 30 seconds to allow working with slow GS servers
