Release Notes

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

Bugfixes

  • Fixed a crash during container creation when an image had no names
  • Fixed default rootfs mount propagation to for containers to match Docker
  • Fixed permissions of /proc in containers
  • Fixed permissions of some default bind mounts (for example, /etc/hosts) in read-only containers
  • Fixed /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

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 mount propagation on volume mounts
  • 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.
