podman top
command did not work on systems using CGroups V2 (#4192) - Fixed a bug where rootless Podman could double-close a file, leading to a panic

- 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
), breakingpodman login
integration withskopeo
and other tools using the containers/image library - Fixed a bug where
podman ps --format=json
andpodman images --format=json
would displaynull
when no results were returned, instead of valid JSON - Fixed a bug where

- 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

--pids-limit 0
topodman create
andpodman run
- The

command now automatically attachesSTDIN
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

- Changed
podman generate kube
to generate Kubernetes service YAML in the same file as pod YAML, generating a single file instead of two - To improve compatibility with the Docker command line,
podman inspect -f '{{ json .ContainerConfig }}'
on images is no longer valid; please usepodman inspect -f '{{ json .Config }}'
instead
- Fixed a bug where an empty path for named volumes could make it impossible to create containers
- Fixed a bug where containers using another container's network namespace would not also use the other container's /etc/hosts and /etc/resolv.conf
- Fixed a bug where containers with
--rm
which failed to start were not removed - Fixed a potential race condition attempting to read
/etc/passwd
inside containers

command to generate Kubernetes Pod and Service YAML for Podman containers and pods - The
podman pod stop
flag now accepts a--timeout
flag to set the timeout for stopping containers in the pod
- Fixed a bug where rootless Podman would fail to start if the default OCI hooks directory is not present
- Rootless Podman now creates the storage.conf, libpod.conf, and mounts.conf configuration files automatically in
~/.config/containers/
for ease of reconfiguration - The
podman pod create
command can expose ports in the pod's network namespace, allowing public services to be created in pods - The

command can now keep containers running after they are checkpointed with the--leave-running
flag - The
podman container checkpoint
andpodman container restore
commands now support the--tcp-established
flag to checkpoint and restore containers with active TCP connections - The
podman version
command now has a--format

podman exec
without-t
would still use a terminal if the container was created with-t
- Fixed a bug where container root propagation was not being properly adjusted if volumes with root propagation set were mounted into the container

could hold the container lock longer than necessary waiting for an exited container - Fixed a bug where rootless containers using
slirp4netns
for networking were reporting usingbridge
networking inpodman inspect
- Fixed a bug where
podman container restore -a
was attempting to restore all containers, including created and running ones. It will now only attempt to restore stopped and exited containers - Fixed a bug where rootless Podman detached containers were not being properly cleaned up

inotify
to wait for container exit files to be created, instead of polling. Ifinotify
cannot be used, Podman will fall back to polling to check if the file has been created - The
podman logs
command now uses improved short-options handling, allowing its flags to be combined if desired (for example,podman logs -lf

- Fixed a bug where full error messages were being lost when creating containers with user namespaces
- Fixed a bug where container state was not properly updated if a failure occurred during network setup, which could cause mounts to be left behind when the container was removed
- Fixed a bug where

- Fixed checkpoint and restore code to verify an appropriate version of
criu
is being used - Fixed a bug where environment variables with no specified value (e.g.
-e FOO
) caused errors (they are now added as empty) - Fixed a bug where rootless Podman would attempt to configure the system firewall, causing errors on some systems where iptables is not in the user's PATH
- Fixed a bug where rootless Podman was unable to successfully write the container ID to a file when
--cid-file
was specified topodman run
- Fixed a bug where
podman unmount
would refuse to unmount a container if it was running (the unmount will now be deferred until the container stops) - Fixed a bug where rootless

CGroup driver was sometimes not successfully removing pod CGroups - Fixed a bug where rootless Podman was unable to run systemd containers (note that this also requires an update to systemd)
- Fixed a bug where
podman run
with the--user
flag would fail if the container image did not contain/etc/passwd
or/etc/group
podman rm
,podman restart
,podman kill
,podman pause
, andpodman unpause
now operate in parallel, greatly improving speed when multiple containers are specifiedpodman create
,podman run
, andpodman ps
have a number of improvements which should greatly increase their speed- Greatly improved performance and reduced memory utilization of container status checks, which should improve the speed of most Podman commands
- 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

podman build
would not work while any containers were running
- Fixed cgroup mount for containers using systemd as init to work properly with the systemd cgroup manager
- Added handling for running containers as users with numeric UIDs not present in the container's /etc/passwd. This allows getpwuid() to work inside these containers.

push
,pull
,login
,logout
,runlabel
, andsearch

--syslog
flag is specified - Fixed manpages for
podman create
andpodman run
to document existing--net
flag as an alias for--network
- Fixed issues with rootless Podman where specifying a single user mapping container was causing all Podman commands to hang
- Fixed an issue with rootless Podman not properly detecting when user namespaces were not enabled

resolv.conf
in container would unconditionally forward nameservers into the container, even localhost - Fixed containers to release resources in the OCI runtime immediately after exiting, improving compatibility with Kata containers
- Fixed OCI runtime handling to fix several issues when using gVisor as an OCI runtime

- Fixed SELinux labelling for containers run with
--security-opt label=disable
to assign the correct label
- Changed flag ordering on all Podman commands to ensure flags are alphabetized

/dev/shm
in--ipc=container
and--ipc=host
containers to use the correct SHM - Fixed rootless Podman to properly join the namespaces of other containers
- Fixed the output of
podman diff
to not display some default changes that will not be committed - Fixed rootless to better handle cases where insufficient UIDs/GIDs are mapped into the container
- Updated Buildah dependency to fix several bugs in
podman build
- Small performance improvement in image handling code to not recalculate digests
- Added
--interval
flag topodman wait
to determine the interval between checks for container status - Added a switch in
libpod.conf
to disable reserving ports for running containers. This lowers the safety of port allocations, but can significantly reduce memory usage. - Added ability to search all the contents of a registry if no image name is specified when using
podman search
- Further fixes for sharing of UTS namespaces within pods
- Fixed a deadlock in containers/storage that could be caused by numerous parallel Podman processes.
- Fixed Podman running into open file limits when many ports are forwarded

- Fixed default mounts under /dev remaining if /dev is bind-mounted into the container
- Fixed rootless
podman create
with no command specified throwing an error
- Added
podman rm --volumes
flag for compatibility with Docker. As Podman does not presently support named volumes, this does nothing for now, but provides improved compatibility with the Docker command line. - Improved error messages from
podman pull
- Podman is no longer being built by default with support for the Devicemapper storage driver. If you are using this storage driver, you should investigate switching to overlayfs.
- Added support for configuring iptables and firewalld firewalls to allow container traffic. This should resolve numerous issues with network access in containers.
It is recommended that you restart your system firewall after installing this release to clear any firewall rules created by older Podman versions. If port forwarding to containers does not work, it is recommended that you restart your system.
- Added initial support for the
podman pod
command as non-root
- Fixed regression where invalid Podman commands would still cause a clean exit

podman rmi --all
to not error if no images are present on the system - Fixed parsing of container logs with
podman logs
to properly handle CRI logging, fixing some issues with blank lines in logs - Fixed a bug creating pod cgroups using the systemd cgroup driver with systemd versions 239 and higher
- Fixed handling of volume mounts that overlapped with default container mounts (for example,
podman run -v /dev/:/dev
) - Fixed sharing of UTS namespace in pods

podman
with a symlinked storage directory crashing - Fixed bug with
podman ps
and multiple filters where the interface did not match Docker - Fixed handling of
resolv.conf
on the host to handle symlinks - Increased open file descriptor and process limits to match Docker and Buildah

podman run
andpodman create
- Fixed

matches - Fixed a bug with privileged rootless containers with
--net=host
set - Fixed a bug where
podman exec --user
would not work with usernames, only numeric IDs - Fixed a bug where Podman was forwarding both TCP and UDP ports to containers when protocol was not specified
