Release v1.3.13
Rancher Kubernetes Engine (RKE) is a CNCF-certified Kubernetes distribution that runs entirely within Docker containers. It works on bare-metal and virtualized servers. With RKE, the installation and operation of Kubernetes are both simplified and easily automated, and they are entirely independent of the operating system and platform you’re running.
Enhancements
- Introduced
v1.24.2-rancher1-1
,v1.23.8-rancher1-1
,v1.22.11-rancher1-1
,v1.21.14-rancher1-1
andv1.20.15-rancher2-2
cri-dockerd
is now enabled by default forv1.24.2-rancher1-1
.- Added retries for etcd snapshot and other improvements; for more details, see #2952.
Bug Fixes
- Fixed an issue where Docker image pull fails from private registry if cri-dockerd is enabled. See #3002.
Known Major Issues
- Ephemeral
/var/lib/dockershim
and/var/lib/cri-dockerd
directories for kubelet container could cause kubelet/dockershim to send empty portMappings after upgrade. The workaround is to bind mount these directories by specifyingextra_binds
for kubelet service. See #2993. - In clusters where
cloud_provider
is configured and eitheraddress
orinternal_address
does not contain a valid IP address (e.g., hostname or FQDN), kube-proxy will fail to start. See #1725.
