[Podman] Podman candidate v5.3.0-rc2 Released

Hi all, Podman candidate v5.3.0-rc2 is now available. You may view the full details at https://github.com/containers/podman/releases/tag/v5.3.0-rc2 Release candidate Notes: -------------- This is the second release candidate for Podman v5.3.0. Preliminary release notes are below. ### Features - The `podman kube generate` and `podman kube play` commands can now create and run Kubernetes Job YAML ([#17011](https://github.com/containers/podman/issues/17011)). - The `podman kube generate` command now includes information on the user namespaces for pods and containers in generated YAML. The `podman kube play` command uses this information to duplicate the user namespace configuration when creating new pods based on the YAML. - The `podman kube play` command now supports Kubernetes volumes of type image ([#23775](https://github.com/containers/podman/issues/23775)). - The service name of systemd units generated by Quadlet can now be set with the `ServiceName` key in all supported Quadlet files ([#23414](https://github.com/containers/podman/issues/23414)). - Quadlets can now disable their implicit dependency on `network-online.target` via a new key, `DefaultDependencies`, supported by all Quadlet files ([#24193](https://github.com/containers/podman/issues/24193)). - Quadlet `.container` and `.pod` files now support a new key, `AddHost`, to add hosts to the container or pod. - The `PublishPort` key in Quadlet `.container` and `.pod` files can now accept variables in its value ([#24081](https://github.com/containers/podman/issues/24081)). - Quadlet `.container` files now support a new key, `CgroupsMode`, to configure cgroups for the container ([#23664](https://github.com/containers/podman/issues/23664)). - Quadlet `.container` files can now use the network of another container by specifying the `.container` file of the container to share with in the `Network` key. - Quadlet `.pod` files now support six new keys, `DNS`, `DNSOption`, `DNSSearch`, `IP`, `IP6`, and `UserNS`, to configure DNS, static IPs, and user namespace settings for the pod ([#23692](https://github.com/containers/podman/issues/23692)). - Quadlet `.image` files can now give an image multiple times by specifying the `ImageTag` key multiple times ([#23781](https://github.com/containers/podman/issues/23781)). - Quadlets can now be placed in the `/run/containers/systemd` directory as well as existing directories like `$HOME/containers/systemd` and `/etc/containers/systemd/users`. - Quadlet now properly handles subdirectories of a unit directory being a symlink ([#23755](https://github.com/containers/podman/issues/23755)). - The `podman manifest inspect` command now includes the manifest's annotations in its output. - The output of the `podman inspect` command for containers now includes a new field, `HostConfig.AutoRemoveImage`, which shows whether a container was created with the `--rmi` option set. - The output of the `podman inspect` command for containers now includes a new field, `Config.ExposedPorts`, which includes all exposed ports from the container, improving Docker compatibility. - The output of the `podman inspect` command for containers now includes a new field, `Config.StartupHealthCheck`, which shows the container's startup healthcheck configuration. - The `podman machine list` command now supports a new option, `--all-providers`, which lists machines from all supported VM providers, not just the one currently in use. - VMs run by `podman machine` on Windows will now provide API access by exposing a Unix socket on the host filesystem which forwards into the VM ([#23408](https://github.com/containers/podman/issues/23408)). - The `podman buildx prune` and `podman image prune` commands now support a new option, `--build-cache`, which will also clean the build cache. - The Windows installer has a new radio button to select virtualization provider (WSLv2 or Hyper-V). - The `--add-host` option to `podman create`, `podman run`, and `podman pod create` now supports specifying multiple hostnames, semicolon-separated (e.g. `podman run --add-host test1;test2:192.168.1.1`) ([#23770](https://github.com/containers/podman/issues/23770)). - The `podman run` and `podman create` commands now support three new options for configuring healthcheck logging: `--health-log-destination` (specify where logs are stored), `--health-max-log-count` (specify how many healthchecks worth of logs are stored), and `--health-max-log-size` (specify the maximum size of the healthcheck log). ### Changes - Podman now uses the Pasta `--map-guest-addr` option by default which is used for the `host.containers.internal` entry in `/etc/hosts` to allow containers to reach the host by default ([#19213](https://github.com/containers/podman/issues/19213)). - The names of the infra containers of pods created by Quadlet are changed to the pod name suffixed with `-infra` ([#23665](https://github.com/containers/podman/issues/23665)). - The `podman system connection add` command now respects HTTP path prefixes specified with `tcp://` URLs. - Proxy environment variables (e.g. `https_proxy`) declared in `containers.conf` no longer escape special characters in their values when used with `podman machine` VMs ([#23277](https://github.com/containers/podman/issues/23277)). - The `podman images --sort=repository` command now also sorts by image tag as well, guaranteeing deterministic output ordering ([#23803](https://github.com/containers/podman/issues/23803)). - When a user has a rootless `podman machine` VM running and second rootful `podman machine` VM initialized, and the rootless VM is removed, the connection to the second, rootful machine now becomes the default as expected ([#22577](https://github.com/containers/podman/issues/22577)). - Environment variable secrets are no longer contained in the output of `podman inspect` on a container the secret is used in ([#23788](https://github.com/containers/podman/issues/23788)). - Podman no longer exits 0 on SIGTERM by default. - Podman no longer explicitly sets rlimits to their default value, as this could lower the actual value available to containers if it had been set higher previously. - Quadlet user units now correctly wait for the network to be ready to use via a new service, `podman-user-wait-network-online.service`, instead of the user session's nonfunctional `network-online.target`. - Exposed ports in the output of `podman ps` are now correctly grouped and deduplicated when they are also published ([#23317](https://github.com/containers/podman/issues/23317)). ### Bugfixes - Fixed a bug where the `--build-context` option to `podman build` did not function properly on Windows, breaking compatibility with Visual Studio Dev Containers ([#17313](https://github.com/containers/podman/issues/17313)). - Fixed a bug where Quadlet would generate bad arguments to Podman if the `SecurityLabelDisable` or `SecurityLabelNested` keys were used ([#23432](https://github.com/containers/podman/issues/23432)). - Fixed a bug where the `PODMAN_COMPOSE_WARNING_LOGS` environment variable did not suppress warnings printed by `podman compose` that it was redirecting to an external provider. - Fixed a bug where, if the `podman container cleanup` command was run on a container in the process of being removed, an error could be printed. - Fixed a bug where rootless Quadlet units placed in `/etc/containers/systemd/users/` would be loaded for root as well when `/etc/containers/systemd` was a symlink ([#23483](https://github.com/containers/podman/issues/23483)). - Fixed a bug where the remote Podman client's `podman stop` command would, if called with `--cidfile` pointing to a non-existent file and the `--ignore` option set, stop all containers ([#23554](https://github.com/containers/podman/issues/23554)). - Fixed a bug where the `podman wait` would only exit only after 20 second when run on a container which rapidly exits and is then restarted by the `on-failure` restart policy. - Fixed a bug where `podman volume rm` and `podman run -v` could deadlock when run simultaneously on the same volume ([#23613](https://github.com/containers/podman/issues/23613)). - Fixed a bug where running `podman mount` on a container in the process of being created could cause a nonsensical error indicating the container already existed ([#23637](https://github.com/containers/podman/issues/23637)). - Fixed a bug where the `podman stop` command could deadlock when run on containers with very large annotations ([#22246](https://github.com/containers/podman/issues/22246)). - Fixed a bug where the `podman machine stop` command could segfault on Mac when a VM failed to stop gracefully ([#23654](https://github.com/containers/podman/issues/23654)). - Fixed a bug where the `podman stop` command would not ensure containers created with `--rm` were removed when it exited ([#22852](https://github.com/containers/podman/issues/22852)). - Fixed a bug where the `--rmi` option to `podman run` did not function correctly with detached containers. - Fixed a bug where running `podman inspect` on a container on FreeBSD would emit an incorrect value for the `HostConfig.Device` field, breaking compatibility with the Ansible Podman module. - Fixed a bug where rootless Podman could fail to start containers using the `--cgroup-parent` option ([#23780](https://github.com/containers/podman/issues/23780)). - Fixed a bug where the `podman build -v` command did not properly handle Windows paths passed as the host directory. - Fixed a bug where Podman could leak network namespace files if it was interrupted while creating a network namespace ([#24044](https://github.com/containers/podman/issues/24044)). - Fixed a bug where the remote Podman client's `podman run` command could sometimes fail to retrieve a container's exit code for containers run with the `--rm` option. - Fixed a bug where `podman machine` on Windows could fail to run VMs for certain usernames containing special characters. - Fixed a bug where Quadlet would reject `RemapUsers=keep-id` when run as root. - Fixed a bug where XFS quotas on volumes were not unique, meaning that all volumes using a quota shared the same maximum size and inodes (set by the most recent volume with a quota to be created). ### API - The Play API for Kubernetes YAML now supports `application/x-tar` compressed context directories ([#24015](https://github.com/containers/podman/pull/24015)). - Fixed a bug in the Attach API for Containers (for both Compat and Libpod endpoints) which could cause inconsistent failures due to a race condition ([#23757](https://github.com/containers/podman/issues/23757)). - Fixed a bug where the output for the Compat Top API for Containers did not properly split the output into an array ([#23981](https://github.com/containers/podman/issues/23981)). - Fixed a bug where the Info API could fail when running `podman system service` via a socket-activated systemd service ([#24152](https://github.com/containers/podman/issues/24152)). ### Misc - Podman now requires Golang 1.22 or higher to build. - The output of `podman machine start` has been improved when trying to start a machine when another is already running ([#23436](https://github.com/containers/podman/issues/23436)). - Quadlet will no longer log spurious ENOENT errors when resolving unit directories ([#23620](https://github.com/containers/podman/issues/23620)). - The Docker alias shell script will now also honor the presence of `$XDG_CONFIG_HOME/containers/nodocker` when considering whether it should print its warning message that Podman is in use. - The podman-auto-update systemd unit files have been moved into the `contrib/systemd/system` directory in the repo for consistency with our other unit files.
