Release Notes

1.9.2

Bugfixes

• Fixed a bug where podman save would fail when the target image was specified by digest (#5234)
• Fixed a bug where rootless containers with ports forwarded to them could panic and dump core due to a concurrency issue (#6018)
• Fixed a bug where rootless Podman could race when opening the rootless user namespace, resulting in commands failing to run
• Fixed a bug where HTTP proxy environment variables forwarded into the container by the --http-proxy flag could not be overridden by --env or --env-file (#6017)
• Fixed a bug where rootless Podman was setting resource limits on cgroups v2 systems that were not using systemd-managed cgroups (and thus did not support resource limits), resulting in containers failing to start

Misc

• Rootless containers will now automatically set their ulimits to the maximum allowed for the user running the container, to match the behavior of containers run as root
• Packages managed by the core Podman team will no longer include a default libpod.conf, instead defaulting to containers.conf. The default libpod.conf will remain available in the Github repository until the release of Podman 2.0
• The default Podman CNI network configuration now sets HairpinMode to allow containers to access other containers via ports published on the host
• Updated containers/common to v0.8.4

1.9.1

Bugfixes

• Fixed a bug where healthchecks could become nonfunctional if container log paths were manually set with --log-path and multiple container logs were placed in the same directory (#5915)
• Fixed a bug where rootless Podman could, when using an older libpod.conf, print numerous warning messages about an invalid CGroup manager config
• Fixed a bug where rootless Podman would sometimes fail to close the rootless user namespace when joining it (#5873)

Misc

• Updated containers/common to v0.8.2

1.9.0

Features

• Experimental support has been added for podman run --userns=auto, which automatically allocates a unique UID and GID range for the new container's user namespace
• The podman play kube command now has a --network flag to place the created pod in one or more CNI networks
• The podman commit command now supports an --iidfile flag to write the ID of the committed image to a file
• Initial support for the new containers.conf configuration file has been added. containers.conf allows for much more detailed configuration of some Podman functionality

Changes

• There has been a major cleanup of the podman info command resulting in breaking changes. Many fields have been renamed to better suit usage with APIv2
• All uses of the --timeout flag have been switched to prefer the alternative --time. The --timeout flag will continue to work, but man pages and --help will use the --time flag instead

Bugfixes

• Fixed a bug where some volume mounts from the host would sometimes not properly determine the flags they should use when mounting
• Fixed a bug where Podman was not propagating $PATH to Conmon and the OCI runtime, causing issues for some OCI runtimes that required it
• Fixed a bug where rootless Podman would print error messages about missing support for systemd cgroups when run in a container with no cgroup support (#5488)
• Fixed a bug where podman play kube would not properly handle container-only port mappings (#5610)
• Fixed a bug where the podman container prune command was not pruning containers in the created and configured states
• Fixed a bug where Podman was not properly removing CNI IP address allocations after a reboot (#5433)
• Fixed a bug where Podman was not properly applying the default Seccomp profile when --security-opt was not given at the command line

HTTP API

• Many Libpod API endpoints have been added, including Changes, Checkpoint, Init, and Restore
• Resolved issues where the podman system service command would time out and exit while there were still active connections
• Stability overall has greatly improved as we prepare the API for a beta release soon with Podman 2.0

Misc

• The default infra image for pods has been upgraded to k8s.gcr.io/pause:3.2 (from 3.1) to address a bug in the architecture metadata for non-AMD64 images
• The slirp4netns networking utility in rootless Podman now uses Seccomp filtering where available for improved security

• Updated containers/image to v5.4.3
• Updated containers/common to v0.8.1

1.8.2

Features

• Initial support for automatically updating containers managed via Systemd unit files has been merged. This allows containers to automatically upgrade if a newer version of their image becomes available

Bugfixes

• Podman will now check the version of conmon that is in use to ensure it is sufficient

1.6.2

Features

• Added a --runtime flag to podman system migrate to allow the OCI runtime for all containers to be reset, to ease transition to the crun runtime on CGroups V2 systems until runc gains full support
• The podman rm command can now remove containers in broken states which previously could not be removed
• The podman info command, when run without root, now shows information on UID and GID mappings in the rootless user namespace
• Added podman build --squash-all flag, which squashes all layers (including those of the base image) into one layer
• The --systemd flag to podman run and podman create now accepts a string argument and allows a new value, always, which forces systemd support without checking if the the container entrypoint is systemd

Bugfixes

• Fixed a bug where rootless Podman could double-close a file, leading to a panic
• Fixed a bug where rootless Podman could fail to retrieve some containers while refreshing the state
• Fixed a bug where podman start --attach --sig-proxy=false would still proxy signals into the container
• Fixed a bug where Podman would unconditionally use a non-default path for authentication credentials (auth.json), breaking podman login integration with skopeo and other tools using the containers/image library
• Fixed a bug where podman ps --format=json and podman images --format=json would display null when no results were returned, instead of valid JSON
• Fixed a bug where podman build --squash was incorrectly squashing all layers into one, instead of only new layers

• Fixed a bug where volumes which failed to unmount could not be removed (#4247)
• Fixed a bug where Podman incorrectly handled some errors relating to unmounted or missing containers in containers/storage
• Fixed a bug where podman stats was broken on systems running CGroups V2 when run rootless (#4268)
• Fixed a bug where the podman start command would print the short container ID, instead of the full ID
• Fixed a bug where containers created with an OCI runtime that is no longer available (uninstalled or removed from the config file) would not appear in podman ps and could not be removed via podman rm
• Fixed a bug where containers restored via podman container restore --import would retain the CGroup path of the original container, even if their container ID changed; thus, multiple containers created from the same checkpoint would all share the same CGroup

Misc

• The default PID limit for containers is now set to 4096. It can be adjusted back to the old default (unlimited) by passing --pids-limit 0 to podman create and podman run
• The podman start --attach command now automatically attaches STDIN if the container was created with -i
• The podman network create command now validates network names using the same regular expression as container and pod names
• The --systemd flag to podman run and podman create will now only enable systemd mode when the binary being run inside the container is /sbin/init, /usr/sbin/init, or ends in systemd (previously detected any path ending in init or systemd)
• Updated vendored Buildah to 1.11.3
• Updated vendored containers/storage to 1.13.5
• Updated vendored containers/image to 4.0.1

1.6.1

Bugfixes

• Improve ability of podman runlabel to run commands that are not Podman
• Podman containers with an IP address now add their hostnames to /etc/hosts
• Changed default location of temporary libpod files in rootless Podman
• Updated the default Podman seccomp profile
