Release Notes

1.4.4

Bugfixes

  • Fixed a bug where rootless Podman would attempt to use the entire root configuration if no rootless configuration was present for the user, breaking rootless Podman for new installations
  • Fixed a bug where rootless Podman's pause process would block SIGTERM, preventing graceful system shutdown and hanging until the system's init send SIGKILL
  • Fixed a bug where running Podman as root with sudo -E would not work after running rootless Podman at least once
  • Fixed a bug where options for tmpfs volumes added with the --tmpfs flag were being ignored
  • Fixed a bug where images with no layers could not properly be displayed and removed by Podman
  • Fixed a bug where locks were not properly freed on failure to create a container or pod

Misc

  • Updated containers/storage to v1.12.13

1.4.3

Features

  • Podman now has greatly improved support for containers using multiple OCI runtimes. Containers now remember if they were created with a different runtime using --runtime and will always use that runtime
  • The cached and delegated options for volume mounts are now allowed for Docker compatability (#3340)
  • The podman diff command now supports the --latest flag

Bugfixes

  • Fixed a bug where podman cp on a single file would create a directory at the target and place the file in it (#3384)
  • Fixed a bug where podman inspect --format '{{.Mounts}}' would print a hexadecimal address instead of a container's mounts
  • Fixed a bug where rootless Podman would not add an entry to container's /etc/hosts files for their own hostname (#3405)
  • Fixed a bug where podman ps --sync would segfault (#3411)

Misc

  • Podman now performs much better on systems with heavy I/O load
  • The --cgroup-manager flag to podman now shows the correct default setting in help if the default was overridden by libpod.conf
  • For backwards compatability, setting --log-driver=json-file in podman run is now supported as an alias for --log-driver=k8s-file. This is considered deprecated, and json-file will be moved to a new implementation in the future (#3363)
  • Podman's default libpod.conf file now allows the crun OCI runtime to be used if it is installed

1.4.2

Bugfixes

  • Fixed a bug where Podman could not run containers using an older version of Systemd as init (#3295)

Misc

  • The Podman remote client can now log to a file if syslog is not available

1.4.1

Features

  • The podman exec command now sets its error code differently based on whether the container does not exist, and the command in the container does not exist
  • The podman inspect command on containers now outputs Mounts JSON that matches that of docker inspect, only including user-specified volumes and differentiating bind mounts and named volumes
  • The podman inspect command now reports the path to a container's OCI spec with the OCIConfigPath key (only included when the container is initialized or running)

  • Fixed a bug where podman import would not properly set environment variables, discarding their values and retaining only keys
  • Fixed a bug where Podman would fail to run when built with Apparmor support but run on systems without the Apparmor kernel module loaded (#3331)

Misc

  • Podman now uses JSON logging with OCI runtimes that support it, allowing for better error reporting
  • Updated vendored Buildah to v1.8.4
  • Updated vendored containers/image to v2.0

1.4.0

Features

  • Fixed a bug where rootless Podman would receive permission denied errors accessing conmon.pid (#3187)
  • Fixed a bug where podman cp with a folder specified as target would replace the folder, as opposed to copying into it (#3184)
  • Fixed a bug where rootless Podman commands could double-unlock a lock, causing a crash (#3207)
  • Fixed a bug where Podman incorrectly set tmpcopyup on /dev/ mounts, causing errors when using the Kata containers runtime (#3229)

0.12.1

Features

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

  • The podman ps command now has a --sync flag to force a sync of Podman's state against the OCI runtime, resolving some state desync errors
  • Added the podman volume set of commands for creating and managing local-only named volumes

Bugfixes

  • Fixed a breaking change in rootless Podman where a change in default paths caused Podman to be unable to function on systems upgraded from 0.10.x or earlier
  • Fixed a bug where podman exec without -t would still use a terminal if the container was created with -t
  • Fixed a bug where container root propogation was not being properly adjusted if volumes with root propogation set were mounted into the container
  • Fixed a bug where podman exec 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 using bridge networking in podman 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
  • Fixed a bug where privileged containers were being mounted with incorrect (too restrictive) mount options such as nodev
  • Fixed a bug where podman stop would throw an error attempting to stop a container that had already stopped
  • Fixed a bug where NOTIFY_SOCKET was not properly being passed into Podman containers
  • Fixed a bug where /dev/shm was not properly mounted in rootless containers
  • Fixed a bug where rootless Podman would set up the CNI plugins for networking (despite not using them in rootless mode), potentially causing inotify related errors
  • Fixed a bug where Podman would error on numeric GIDs that do not exist in the container's /etc/group
  • Fixed a bug where containers in pods or created with --net=container were not mounting /etc/resolv.conf and /etc/hosts

  • Improved podman runlabel support for labels featuring arguments with whitespace
  • Containers without a network namespace will now use the host's resolv.conf
  • The slirp4netns network mode can now be used with containers running as root. It may be useful for container-in-container scenarios where the outer container does not have host networking set
  • Podman now uses inotify to wait for container exit files to be created, instead of polling. If inotify 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 instead of podman logs -l -f)
  • Hardcoded OCI hooks directories used by Podman are now deprecated; they should instead be coded into the libpod.conf configuration file. They can be specified as an array via hooks_dir

0.11.1.1

Bugfixes

  • Fixed a bug where Podman was not correctly adding firewall rules for containers, preventing them from accessing the network
  • 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 podman exec could time out on slower systems by increasing the relevant timeout

Misc

  • podman rm -f now removes paused containers. As such, podman rm -af completing successfully guarantees all Podman containers have been removed
  • Added a field to podman info to show if Podman is being run as rootless
  • Made a small output format change to podman images - image sizes now feature a space between number and unit (e.g. 123 MB now instead of 123MB)
  • Vendored an updated version of containers/storage to fix several bugs reported upstream

0.11.1

Features

  • Added --all and --latest flags to podman checkpoint and podman restore
  • Added --max-workers flag to all Podman commands that support operating in parallel, allowing the maximum number of parallel workers used to be specified
  • Added --all flag to podman restart

Bugfixes

  • Fixed a bug where container status checks would sometimes leave zombie OCI runtime processes
  • 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 to podman 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 podman attach would fail to attach due to a too-long path name

  • 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

Misc

  • podman rm, podman restart, podman kill, podman pause, and podman unpause now operate in parallel, greatly improving speed when multiple containers are specified
  • podman create, podman run, and podman 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
  • Updated the default Podman seccomp profile

Compatability

Several paths related to rootless Podman had their default values changed in this release. If paths were not hardcoded in libpod.conf, your system may lose track of running containers and believe they are newly-created.

0.10.1.3

Bugfixes

  • Fixed a bug where podman build would not work while any containers were running

0.10.1.2

Bugfixes

  • Fixed cgroup mount for containers using systemd as init to work properly with the systemd cgroup manager

0.10.1.1

Features

  • 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.
  • Added support for the REGISTRY_AUTH_FILE environment variable, which specifies the location of credentials for registry login. This is supported by the push, pull, login, logout, runlabel, and search commands

Bugfixes

  • Fixed handling for image volumes which are mounted on symlinks. The links are now resolved within the container, not on the host

0.9.3.1

Bugfixes

  • Fixed a critical issue where SELinux contexts set on tmpfs volumes were causing runc crashes

0.9.3

Features

  • Added a flag to libpod.conf, label, to globally enable/disable SELinux labelling for libpod
  • Added --mount flag to podman create and podman run as a new, more explicit way of specifying volume mounts

  • 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

0.9.2.1

Bugfixes

  • Updated Buildah dependency to fix several bugs in podman build

Misc

  • Small performance improvement in image handling code to not recalculate digests

0.9.2

Features

  • Added --interval flag to podman 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

Bugfixes

  • 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

Misc

  • Added podman rm --volumes flag for compatability with Docker. As Podman does not presently support named volumes, this does nothing for now, but provides improved compatability with the Docker command line.
  • Improved error messages from podman pull

Compatability

  • 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.

0.9.1.1

Bugfixes

  • Added support for configuring iptables and firewalld firewalls to allow container traffic. This should resolve numerous issues with network access in containers.

Note

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.

0.9.1

Features

  • Added initial support for the podman pod command as non-root

Bugfixes

  • Fixed regression where invalid Podman commands would still cause a clean exit
  • Fixed 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

Misc

  • Added additional debug information when pulling images if --log-level=debug is specified
  • podman build now defaults to caching intermediate layers while building

0.8.5

Features

  • Added the ability to add a multipart entrypoint with podman run --entrypoint
  • Improved help text when invalid commands are specified
  • Greatly improved support for containers which use systemd as init

Bugfixes

  • Fixed several bugs with rootless podman exec
  • Fixed rootless 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
  • Fixed podman run -h to specify the container's hostname (as it does in Docker) instead of printing help text
  • Fixed a bug with image shortname handling where repositories were incorrectly being treated as registries
  • Fixed a bug where podman wait was busywaiting and consuming large amounts of CPU

0.8.4

Features

  • Added the podman pod top command
  • Added the ability to easily share namespaces within a pod
  • Added a pod statistics endpoint to the Varlink API
  • Added information on container capabilities to the output of podman inspect

Bugfixes

  • Fixed a bug with the --device flag in podman run and podman create
  • Fixed podman pod stats to accept partial pod IDs and pod names
  • Fixed a bug with OCI hooks handling ALWAYS 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
  • Fixed issues with Apparmor in rootless containers
  • Fixed an issue with database encoding causing some containers created by Podman versions 0.8.1 and below to be unusable.

Compatability:

We switched JSON encoding/decoding to a new library for this release to address a compatability issue introduced by v0.8.2. However, this may cause issues with containers created in 0.8.2 and 0.8.3 with custom DNS servers.
