podman 1.4 now installs docker man pages. Add handler to remove docker packages to avoid test failure due to this conflict.
Adjust inventory_docker_swarm integration test
Add conditional to cleanup handlers to allow use of the setup_docker role without removing packages at the end of the play. The inventory_docker_swarm integration tests does its own cleanup.
- use include_vars to set appropriate packages and pip packages per distribution and version
- install an older version of Docker CE on RHEL 8 since a dependency is unavailable
- disable warnings on tasks that are ok
- skip tests for CentOS/RHEL 6
Some integration test targets have dependencies on files outside
the `test/integration/targets/` directory tree. Changes to these
dependencies can result in unexpected test failures since they do
not trigger integration tests which depend on them.
* Store parsed docker-py / docker API versions in client.
* Began refactoring 'minimal required version' for docker_container options.
* Removing some fake defaults.
* Added changelog.
* Improve tests (check older docker versions).
* Fix comparison. The breaking point is not docker-py 2.0.0, but 1.10.0.
(Verified by testing with these versions.)
* Move docker-py/API version detection to setup_docker.
* Add YAML document starter.
* docker_network requirement for docker-py was bumped to 1.10.0 in #47492.
