* Move copying functionality to module_utils. * Add docker_container_copy_into module. * Use new module in other tests. * Fix copyright and attributes. * Improve idempotency, improve stat code. * Document and test when a stopped container works. * Improve owner/group detection error handling when container is stopped. * Fix formulation. Co-authored-by: Brian Scholer <1260690+briantist@users.noreply.github.com> * Improve file comparison. * Avoid reading whole file at once. * Stream when fetching files from daemon. * Fix comment. * Use read() instead of read1(). * Stream files when copying into container. * Linting. * Add force parameter. * Simplify library code. * Linting. * Add content and content_is_b64 options. * Make force=false work as for copy module: only copy if the destination does not exist. * Improve docs. * content should be no_log. * Implement diff mode. * Improve error handling. * Lint and improve. * Set owner/group ID to avoid ID lookup (which fails in paused containers). * Apply suggestions from code review Co-authored-by: Brian Scholer <1260690+briantist@users.noreply.github.com> Co-authored-by: Brian Scholer <1260690+briantist@users.noreply.github.com>
