Application publishing

• Do not publish an application and perform O&M operations on it at the same time.

• The following operations cause pods to be deleted and recreated during application publishing, rather than being upgraded in-place:

  • Changing the CPU and memory values of pods.

  • Rolling back from a version with real-time monitoring enabled to a version where monitoring is disabled.

  • Changing the number of containers in a pod.

• Changing the SLB associated with an application version causes a service interruption.

Cluster management

• You cannot delete or update clusters. For example, you cannot update the vSwitches or security groups in the cluster's zone, or update cluster monitoring configurations.

• Cluster quota: Each workspace is limited to one cluster.

• The pod and Service CIDR blocks for a cluster cannot be changed after the cluster is created.

• When you delete nodes, subscription instances cannot be deleted. You can only wipe their disks.

• When accessing a cluster using a generated certificate:

  • Access is restricted to the VPC. Public network access is not supported.

  • You cannot obtain Finance Cloud extension resources, such as CafeDeployment and inplaceset.

• The container web console has a session timeout of 1 minute.

Images

• Image building: You can run a maximum of three concurrent build tasks.

• Image Center: You can only push images to your tenant's namespace or pull images from the public namespace. The Image Center is only accessible from within its region.
