A new Couchbase test container has been developed, allowing users to easily configure and run Couchbase clusters during tests without having to build their own Docker images. The container uses the official Couchbase Docker image and provides a custom waiting strategy for liveness checks. Users can configure the cluster by making API calls to set up ram quotas, usernames and passwords, and available services. The container also supports exposing multiple ports and setting HTTP wait strategies. This allows developers to easily test Couchbase without requiring extensive knowledge of Docker or Couchbase configuration.
