Symptoms
In the Event Streams UI, if you have only topic-level ACLs, such as topic.read and topic.create, you cannot create topics, and the Create button in the Create topic window is disabled.
Causes
When creating a topic, the UI validates that the replication factor and minimum in-sync replicas values are less than the broker count.
To retrieve the broker count for this validation, the following cluster ACLs are required:
cluster.describecluster.describeConfigs
If you do not have these cluster-level permissions, the UI cannot complete the validation, and topic creation is blocked.
Resolving the problem
Use one of the following workarounds to avoid this problem:
Grant cluster permissions
Ensure that you have the following cluster ACLs:
cluster.describecluster.describeConfigs
For more information about managing access and ACLs, see managing access.
Create topics by using the CLI
If cluster permissions cannot be granted, create topics by using the Event Streams CLI instead of the UI.
For example:
kubectl es topic-create --name my-topic --partitions 1 --replication-factor 1 --config retention.ms=86400000
