We are stoked to announce the release of: magnum 9.4.0: Container Management project for OpenStack This release is part of the train stable release series. The source is available from: https://opendev.org/openstack/magnum Download the package from: https://tarballs.openstack.org/magnum/ Please report issues through: https://bugs.launchpad.net/magnum/+bugs For more details, please see below. 9.4.0 ^^^^^ New Features ************ * The default 10 seconds health polling interval is too frequent for most of the cases. Now it has been changed to 60s. A new config *health_polling_interval* is supported to make the interval configurable. Cloud admin can totally disable the health polling by set a negative value for the config. * New labels to support containerd as a runtime. container_runtime The container runtime to use. Empty value means, use docker from the host. Since ussuri, apart from empty (host- docker), containerd is also an option. containerd_version The containerd version to use as released in https://github.com/containerd/containerd/releases and https://storage.googleapis.com/cri-containerd-release/ containerd_tarball_url Url with the tarball of containerd's binaries. containerd_tarball_sha256 sha256 of the tarball fetched with containerd_tarball_url or from https://storage.googleapis.com/cri- containerd-release/. Upgrade Notes ************* * If it's still preferred to have 10s health polling interval for Kubernetes cluster. It can be set by config *health_polling_interval* under *kubernetes* section. Bug Fixes ********* * Fix an issue with private clusters getting stuck in CREATE_IN_PROGRESS status where floating_ip_enabled=True in the cluster template but this is disabled when the cluster is created. * The taint of master node kubelet has been improved to get the conformance test (sonobuoy) passed. * For fcos-kubelet, add rpc-statd dependency. To mount nfs volumes with the embedded volume pkg [0], rpc-statd is required and should be started by mount.nfs. When running kubelet in a chroot this fails. With atomic containers it used to work.
