What’s new¶
MKE now gives users the option to send the log and a support bundle to Mirantis Support when an upgrade fails (MKE-8133).
MKE now includes a
pod-cidr
check in the MKE installer when using the VXLAN dataplane in an Azure environment (FIELD-3903).Using the new
--kubelet-data-root
flag withucp install
, you can now configure the kubelet data root directory on Linux systems during new MKE installations (MKE-8268).Using the new
--containerd-root
flag withucp install
, you can now configure the containerd root directory on Linux systems during new MKE installations. Any non-root directory containerd customizations must be made along with the root directory customizations prior to installation and with the--containerd-root
flag omitted (MKE-7949).
Bug fixes¶
Fixed an issue wherein the default Interlock NGINX proxy
server_names_hash_bucket_size
could not handle very long host names, sometimes causing existing services to become unreachable.server_names_hash_bucket_size
is now fully adaptive within hard bounds. (MKE-8262).Fixed broken links to MKE documentation in the MKE web UI (FIELD-3459, FIELD-3683, FIELD-3839, FIELD-3843, FIELD-3845).
Fixed an issue wherein enabling
HitlessServiceUpdate
while a proxy update is in progress caused the proxy update to stop (FIELD-3623).Fixed an issue wherein opening a network policy with
matchExpressions
returned a blank page in the MKE web UI (FIELD-2834).Fixed an issue wherein two files remained in the
ucp-backup
volume (/var/lib/docker/volumes/ucp-backup
) after the completion of the back-up process. Now, following back-up, only the back-up archive and log file (if included) remain (FIELD-3612).Fixed an issue wherein users could not change new swarm configurations to use a non-default collection (FIELD-2297).
Fixed an issue wherein logs for pods with multiple containers did not display. The pods log view now includes a container selector (FIELD-3582).
Fixed an issue wherein MKE erroneously reported
disconnected
for drained nodes (FIELD-3771).Fixed an issue wherein the NVIDIA device plugin became unhealthy after MKE upgrade (FIELD-3626).
Fixed an issue with the MKE web UI wherein clicking on a gateway with an invalid configuration produced a blank page (FIELD-2562).
