Features

  • The podman kube play command now supports the hostIPC field (#17157).
  • The podman kube play command now supports a new flag, --wait, that keeps the workload running in foreground until killed with a sigkill or sigterm. The workloads are cleaned up and removed when killed (#14522).
  • The podman kube generate and podman kube play commands now support SELinux filetype labels.
  • The podman kube play command now supports sysctl options (#16711).
  • The podman kube generate command now supports generating the Deployments (#17712).
  • The podman machine inspect command now shows information about named pipe addresses on Windows (#16860).
  • The --userns=keep-id option for podman create, run, and kube play now works for root containers by copying the current mapping into a new user namespace (#17337).
  • A new command has been added, podman secret exists, to verify if a secret with the given name exists.
  • The podman kube generate and podman kube play commands now support ulimit annotations (#16404).
  • The podman create, run, pod create, and pod clone commands now support a new option, --shm-size-systemd, that allows limiting tmpfs sizes for systemd-specific mounts (#17037).
  • The podman create and run commands now support a new option, --group-entry which customizes the entry that is written to the /etc/group file within the container when the --user option is used (#14965).
  • The podman create and podman run commands now support a new option, --security-opt label=nested, which allows SELinux labeling within a confined container.
  • A new command, podman machine os apply has been added, which applies OS changes to a Podman machine, from an OCI image.
  • The podman search command now supports two new options: --cert-dir and --creds.
  • Defaults for the --cgroup-config option for podman create and podman run can now be set in containers.conf.
  • Podman now supports auto updates for containers running inside a pod (#17181).
  • Podman can now use a SQLite database as a backend for increased stability. The default remains the old database, BoltDB. The database to use is selected through the database_backend field in containers.conf.
  • Netavark plugin support has been added. The netavark network backend now allows users to create custom network drivers. podman network create -d <plugin> can be used to create a network config for your plugin and then Podman will use it like any other config and takes care of setup/teardown on container start/stop. This requires at least Netavark version 1.6.
  • DHCP with macvlan and the netavark backend is now supported.

Changes

  • Remote builds using the podman build command no longer allows .containerignore or .dockerignore files to be symlinks outside the build context.
  • The podman system reset command now clears build caches.
  • The podman play kube command now adds ctrName as an alias to the pod network (#16544).
  • The podman kube generate command no longer adds hostPort to the pod spec when generating service kinds.
  • Using a private cgroup namespace with systemd containers on a cgroups v1 system will explicitly error (this configuration has never worked) (#17727).
  • The SYS_CHROOT capability has been re-added to the default set of capabilities.
  • Listing large quantities of images with the podman images command has seen a significant performance improvement (#17828).

Quadlet

  • Quadlet now supports the Rootfs= option, allowing containers to be based on rootfs in addition to image.
  • Quadlet now supports the Secret key in the Container group.
  • Quadlet now supports the Logdriver key in .container and .kube units.
  • Quadlet now supports the Mount key in .container files (#17632).
  • Quadlet now supports specifying static IPv4 and IPv6 addresses in .container files via the IP= and IP6= options.
  • Quadlet now supports health check configuration in .container files.
  • Quadlet now supports relative paths in the Volume key in .container files (#17418).
  • Quadlet now supports setting the UID and GID options for --userns=keep-id (#17908).
  • Quadlet now supports adding tmpfs filesystems through the Tmpfs key in .container files (#17907).
  • Quadlet now supports the UserNS option in .container files, which will replace the existing RemapGid, RemapUid, RemapUidSize and RemapUsers options in a future release (#17984).
  • Quadlet now includes a --version option.
  • Quadlet now forbids specifying SELinux label types, including disabling selinux separation.
  • Quadlet now does not set log-driver by default.
  • Fixed a bug where Quadlet did not recognize paths starting with systemd specifiers as absolute (#17906).

Bugfixes

  • Fixed a bug in the network list API where a race condition would cause the list to fail if a container had just been removed (#17341).
  • Fixed a bug in the podman image scp command to correctly use identity settings.
  • Fixed a bug in the remote Podman client's podman build command where building from stdin would fail. podman --remote build -f - now works correctly (#17495).
  • Fixed a bug in the podman volume prune command where exclusive (!=) filters would fail (#17051).
  • Fixed a bug in the --volume option in the podman create, run, pod create, and pod clone commands where specifying relative mappings or idmapped mounts would fail (#17517).
  • Fixed a bug in the podman kube play command where a secret would be created, but nothing would be printed on the terminal (#17071).
  • Fixed a bug in the podman kube down command where secrets were not removed.
  • Fixed a bug where cleaning up after an exited container could segfault on non-Linux operating systems.
  • Fixed a bug where the podman inspect command did not properly list the network configuration of containers created with --net=none or --net=host (#17385).
  • Fixed a bug where containers created with user-specified SELinux labels that created anonymous or named volumes would create those volumes with incorrect labels.
  • Fixed a bug where the podman checkpoint restore command could panic.
  • Fixed a bug in the podman events command where events could be returned more than once after a log file rotation (#17665).
  • Fixed a bug where errors from systemd when restarting units during a podman auto-update command were not reported.
  • Fixed a bug where containers created with the --health-on-failure=restart option were not restarting when the health state turned unhealthy (#17777).
  • Fixed a bug where containers using the slirp4netns network mode with the cidr option and a custom user namespace did not set proper DNS IPs in resolv.conf.
  • Fixed a bug where the podman auto-update command could fail to restart systemd units (#17607).
  • Fixed a bug where the podman play kube command did not properly handle secret.items in volumes (#17829).
  • Fixed a bug where the podman generate kube command could generate pods with invalid names and hostnames (#18054).
  • Fixed a bug where names of limits (such as RLIMIT_NOFILE) passed to the --ulimit option to podman create and podman run were case-sensitive (#18077).
  • Fixed a possible corruption issue with the configuration state of podman machine during system failures on Mac, Linux, and Windows.

API

  • The Compat Stats endpoint for Containers now returns the Id key as lowercase id to match Docker (#17869).
  • Fixed a bug where the Compat top endpoint incorrectly returned titles as a string instead of a list (#17524).
