Podman Release 1.1.0

Podman has gone 1.1!

Some of the new features include the ability to forward ports as rootless Podman, adding short options to some of the existing command options, added --all-tags to the the pull command, further changes for rootless containers and more. All the details follow!

Changes

Features

• Rootless Podman can now forward ports into containers (using the same -p and -P flags as root Podman)

• Added an alias -f for the –format flag of the podman info and podman version commands
• Added an alias -s for the –size flag of the podman inspect command

• Added the podman system renumber command to handle lock changes
• The –net=host and –dns flags for podman run and podman create no longer conflict
• Podman now handles mounting the shared /etc/resolv.conf from network namespaces created by ip netns add when they are passed in via podman run –net=ns:

Bugfixes

• Fixed a bug where invalid named volumes specified in podman create and podman run could cause segfaults #2301
• Fixed a bug where the runtime field in libpod.conf was being ignored. runtime is legacy and deprecated, but will continue to be respected for the foreseeable future

Misc

• Podman migrated to a new, shared memory locking model in this release. As part of this, if you are running Podman with pods or dependency containers (e.g. –net=container:), you should run the podman system renumber command to migrate your containers to the new model - please reference the podman-system-renumber(1) man page for further details
• Podman migrated to a new command-line parsing library, and the output format of help and usage text has somewhat changed as a result
• Updated Buildah to v1.7, picking up a number of bugfixes
• Updated containers/image library to v1.5, picking up a number of bugfixes and performance improvements to pushing images
• Updated containers/storage library to v1.10, picking up a number of bugfixes
• Work on the remote Podman client for interacting with Podman remotely over Varlink is progressing steadily, and many image and pod commands are supported
• Added path masking to mounts with the :z and :Z options, preventing users from accidentally performing an SELinux relabel of their entire home directory
• The podman container runlabel command will not pull an image if it does not contain the requested label
• Many commands’ usage information now includes examples
• podman rm can now delete containers in containers/storage, which can be used to resolve some situations where Podman fails to remove a container
• The podman search command now searches multiple registries in parallel for improved performance
• The podman build command now defaults –pull-always to true
• Containers which share a network namespace (for example, when in a pod) will now share /etc/hosts and /etc/resolv.conf between all containers in the pod, causing changes in one container to propagate to all containers sharing their networks
• The podman rm and podman rmi commands now return 1 (instead of 127) when all specified container or images are missing
