This is presently only supported with the `crun` OCI runtime +- The `podman volume rm` and `podman volume inspect` commands can now refer to volumes by an unambiguous partial name, in addition to full name (e.g. `podman volume rm myvol` to remove a volume named `myvolume`) ([#3891](https://github.com/containers/libpod/issues/3891)) +- The `podman run` and `podman create` commands now support the `--pull` flag to allow forced re-pulling of images ([#3734](https://github.com/containers/libpod/issues/3734)) +- Mounting volumes into a container using `--volume`, `--mount`, and `--tmpfs` now allows the `suid`, `dev`, and `exec` mount options (the inverse of `nosuid`, `nodev`, `noexec`) ([#3819](https://github.com/containers/libpod/issues/3819)) +- The `podman push` command now supports the `--digestfile` option to save a file containing the pushed digest +- Pods can now have their hostname set via `podman pod create --hostname` or providing Pod YAML with a hostname set to `podman play kube` ([#3732](https://github.com/containers/libpod/issues/3732)) +- The `podman image sign` command now supports the `--cert-dir` flag +- The `podman run` and `podman create` commands now support the `--security-opt label=filetype:$LABEL` flag to set the SELinux label for container files +- The remote Podman client now supports healthchecks + +### Bugfixes +- Fixed a bug where remote `podman pull` would panic if a Varlink connection was not available ([#4013](https://github.com/containers/libpod/issues/4013)) +- Fixed a bug where `podman exec` would not properly set terminal size when creating a new exec session ([#3903](https://github.com/containers/libpod/issues/3903)) +- Fixed a bug where `podman exec` would not clean up socket symlinks on the host ([#3962](https://github.com/containers/libpod/issues/3962)) +- Fixed a bug where Podman could not run systemd in containers that created a CGroup namespace +- Fixed a bug where `podman prune -a` would attempt to prune images used by Buildah and CRI-O, causing errors ([#3983](https://github.com/containers/libpod/issues/3983)) +- Fixed a bug where improper permissions on the `~/.config` directory could cause rootless Podman to use an incorrect directory for storing some files +- Fixed a bug where the bash completions for `podman import` threw errors +- Fixed a bug where Podman volumes created with `podman volume create` would not copy the contents of their mountpoint the first time they were mounted into a container ([#3945](https://github.com/containers/libpod/issues/3945)) +- Fixed a bug where rootless Podman could not run `podman exec` when the container was not run inside a CGroup owned by the user ([#3937](https://github.com/containers/libpod/issues/3937)) +- Fixed a bug where `podman play kube` would panic when given Pod YAML without a `securityContext` ([#3956](https://github.com/containers/libpod/issues/3956)) +- Fixed a bug where Podman would place files incorrectly when `storage.conf` configuration items were set to the empty string ([#3952](https://github.com/containers/libpod/issues/3952)) +- Fixed a bug where `podman build` did not correctly inherit Podman's CGroup configuration, causing crashed on CGroups V2 systems ([#3938](https://github.com/containers/libpod/issues/3938)) +- Fixed a bug where `podman cp` would improperly copy files on the host when copying a symlink in the container that included a glob operator ([#3829](https://github.com/containers/libpod/issues/3829)) +- Fixed a bug where remote `podman run --rm` would exit before the container was completely removed, allowing race conditions when removing container resources ([#3870](https://github.com/containers/libpod/issues/3870)) +- Fixed a bug where rootless Podman would not properly handle changes to `/etc/subuid` and `/etc/subgid` after a container was launched +- Fixed a bug where rootless Podman could not include some devices in a container using the `--device` flag ([#3905](https://github.com/containers/libpod/issues/3905)) +- Fixed a bug where the `commit` Varlink API would segfault if provided incorrect arguments ([#3897](https://github.com/containers/libpod/issues/3897)) +- Fixed a bug where temporary files were not properly cleaned up after a build using remote Podman ([#3869](https://github.com/containers/libpod/issues/3869)) +- Fixed a bug where `podman remote cp` crashed instead of reporting it was not yet supported ([#3861](https://github.com/containers/libpod/issues/3861)) +- Fixed a bug where `podman exec` would run as the wrong user when execing into a container was started from an image with Dockerfile `USER` (or a user specified via `podman run --user`) ([#3838](https://github.com/containers/libpod/issues/3838)) +- Fixed a bug where images pulled using the `oci:` transport would be improperly named +- Fixed a bug where `podman varlink` would hang when managed by systemd due to SD_NOTIFY support conflicting with Varlink ([#3572](https://github.com/containers/libpod/issues/3572)) + +### Misc +- Significant changes were made to Podman volumes in this release. If you have pre-existing volumes, it is strongly recommended to run `podman system renumber` after upgrading. +- Version 0.8.1 or greater of the CNI Plugins is now required for Podman +- Version 2.0.1 or greater of Conmon is strongly recommended +- Updated vendored Buildah to v1.11.2 +- Improved error messages when trying to run `podman pause` or `podman stats` on a rootless container on a system without CGroups V2 enabled +- `TMPDIR` has been set to `/var/tmp` by default to better handle large temporary files +- `podman wait` has been optimized to detect stopped containers more rapidly +- Podman containers now include a `ContainerManager` annotation indicating they were created by `libpod` +- The `podman info` command now includes information about `slirp4netns` and `fuse-overlayfs` if they are available +- Podman no longer sets a default size of 65kb for tmpfs filesystems +- The default Podman CNI network has been renamed in an attempt to prevent conflicts with CRI-O when both are run on the same system. This should only take effect on system restart +- The output of `podman volume inspect` has been more closely matched to `docker volume inspect` + ## 1.5.1 ### Features - The hostname of pods is now set to the pod's name diff --git a/changelog.txt b/changelog.txt index b0a847aee..c2c2a8ce9 100644 --- a/changelog.txt +++ b/changelog.txt @@ -1,3 +1,162 @@ +- Changelog for v1.6.0-rc1 (2019-09-16) + * Fix default to pause in podman cp + * Update release notes for v1.6.0 + * Vendor Bulidah 1.11.2 + * get runtime for podman-remote push earlier + * rootless: report the correct error + * Report errors when trying to pause rootless containers + * Do not support wildcards on cp + * Podman-remote run should wait for exit code + * Use exit code constants + * exec: Register resize func a bit later + * clean up after healthcheck execs + * enhance podman network rm + * Add podman icon to installer + * Test that PTYs created by 'podman exec --tty' have the ONLCR flag + * Prevent podman varlink socket fight + * Touch up some bad grammar in rootless doc + * linux: fix systemd with --cgroupns=private + * rootless: run pause process in its own scope + * rootless: automatically create a systemd scope + * utils: use the user session for systemd + * Support building Windows msi file + * Add cgroup v2 info to rootless tutorial + * fix podman sign signature store for rootless + * podman-remote image trust is broken + * Cirrus: Fix unnecessary setsebool + * Add further fields to StorageContainer + * Volume lookup needs to include state to unmarshal into + * Do not prune images being used by a container + * Add support for launching containers without CGroups + * add lint and manpage check to make validate + * Add `ContainerManager` annotation to created containers + * When first mounting any named volume, copy up + * Add function for looking up volumes by partial name + * hack/man_page_checker -
