Changelog since v1.18.0
Changes by Kind
Dependency-Change
API Change
- CRI-O now manages namespace lifecycles by default (manage_ns_lifecycle = true). The config option manage_network_ns_lifecycle has also been fully deprecated (#3929, @haircommander)
Feature
- Add –version-file-persist, a place to put the version file in persistent storage. Now, crio wipe wipes containers if –version-file is not present (presumably it is on temporary storage), and wipes images if both –version-file and –version-file-persist are out of date (presumably there has been an upgrade of cri-o’s minor version (#3648, @haircommander)
- Add big_files_temporary_dir to allow customization of where large temporary files are put (#3935, @adawolfs)
- Add build support for setting SOURCE_DATE_EPOCH (#3708, @afbjorklund)
- Added
--metrics-socket/metrics_socket configuration option to allow exposing the metrics endpoint on a local socket path (#3724, @saschagrunert)
- Added
crio_image_layer_reuse metric which counts layer reuses during image pull (#4053, @saschagrunert)
- Added
privileged field to container status info (#3777, @saschagrunert)
- Added behavior to allow filtering by a partial Pod Sandbox ID (#4033, @saschagrunert)
- Added configuration validation to ensure a
conmon_cgroup == "pod" if cgroup_manager == "cgroupfs" (#3940, @saschagrunert)
- Added latest
crun version to static binary bundle (#3837, @saschagrunert)
- Added metrics-exporter and documentation (#3751, @saschagrunert)
- Added new metrics
crio_image_pulls_failures and crio_image_pulls_successes. For more information please refer to the CRI-O metrics guide (#3809, @saschagrunert)
- Container HostPort with SCTP protocol is supported. (#3874, @janosi)
- Containers running
init or systemd are now given a new selinux label container_init_t, giving it selinux privileges more appropriate for the workload (#3754, @haircommander)
- If users want the container_kvm_t label when using a runtime that supports kvm separation, they will need to either set the runtime_type to “vm” or have “kata” in the runtime name. E.g
[crio.runtime.runtimes.my-kata-runtime]
runtime_path = “”
runtime_type = “oci”
runtime_root = “/run/kata”
or
[crio.runtime.runtimes.my-kata-runtime]
runtime_path = “”
runtime_type = “vm”
runtime_root = “/run/kata” (#3861, @umohnani8)
- Re-add the behavior that string slices can be passed to the CLI comma separated, for example
--default-capabilities CHOWN,KILL (#3636, @saschagrunert)
- Removed
socat runtime dependency which was needed for pod port forwarding (#3749, @saschagrunert)
- Return pod image, pid and spec in sandbox_status CRI verbose mode (#3819, @mrunalp)
Design
Documentation
Bug or Regression
- Adding additional runtime handler doesn’t require the user to copy existing default runtime handler configuration. The existing default runtime handler configuration will be preserved while adding the new runtime handler. (#3772, @harche)
- ExecSync requests will ask conmon to not double fork, causing systemd to have fewer conmons re-parented to it. conmon v2.0.19 or greater is required for this feature. (#3908, @haircommander)
- Fix handling of the –cni-plugin-dir and other multivalue command line flags (#3870, @rhafer)
- Fix path to bash via
/usr/bin/env in crio-shutdown.service (#3971, @saschagrunert)
- Fix the container cgroup in case cgroupfs cgroup manager is used (#4075) (#4080, @kolyshkin)
- Fix working set calculation (#4068, @kolyshkin)
- Fixed
crio version binary mode parsing on musl toolchains (#3969, @saschagrunert)
- Fixed a bug where crictl only showed pod level stats, not container level stats. (#3933, @wgahnagl)
- Fixed a bug where exec sync requests (manually or automatically triggered via readiness/liveness probes) overwrite
the runtime
info.runtimeSpec.process.args of the container status (for example via crictl inspect). (#3989, @saschagrunert)
- Fixed bug where Pod creation would fail if Uid was not specified in Metadata of sandbox config passed in a run pod sandbox request (#3774, @haircommander)
- Fixed bug where pod names would sometimes leak on creation, causing the kubelet to fail to recreate (#3964, @haircommander)
- Fixed crio restart behavior to make sure that Pod creation timestamps are restored and the order in the list of pods stays stable across restarts (#4006, @rhafer)
- Fixed wrong linkmode output (on
crio version) for static binaries (#3638, @saschagrunert)
- Reflects resource updates under the container spec. (#3978, @cynepco3hahue)
Other (Cleanup or Flake)
- Added info logs for image pulls and image status (#3843, @mrunalp)
- Cleanup default info logging (#3834, @mrunalp)
- Cleanup go module and vendor files. (#3722, @mrunalp)
- Pod creation now fails if conmon cannot be moved to the cgroup specified in
conmon_cgroup. Our default value for conmon_cgroup is system.slice, which is invalid for cgroupfs. As such, if you use cgroupfs, you should change conmon_cgroup to pod (#3810, @haircommander)
- Removed
crio-wipe.service and crio-shutdown.service systemd units from the static bundle since they are not required (#3689, @saschagrunert)
Uncategorized
- Adds a new optional field, runtime_type, to the “–runtimes” option. (#3903, @fidencio)
- Cleanup and update nix derivation for static builds (#3804, @hswong3i)
- Fix a bug where a sudden reboot causes incomplete image writes. This could cause image storage to be corrupted, resulting in an error
layer not known. (#3975, @openshift-cherrypick-robot)
- Fixes panic when /sys/fs/cgroup can’t be stat’ed (#3973, @haircommander)
- If the default_runtime is changed from the default configuration, the corresponding existing default entry in the runtime map in the configuration will be ignored. (#4097, @harche)
- Remove support for
--runtime flag (#4107, @haircommander)
