Moving from a High Availability Deployment to a Single Instance

This topic provides instructions to follow should you need to move from a clustered, highly available Nexus Repository deployment to a single instance.

Container-Based Instructions

1. Scale replicas to 0 in the deployment.yml or using the kubectl.
2. In your $data-dir/sonatype-work/nexus3/etc/nexus.properties, set nexus.datastore.clustered.enabled to false.
3. Set nexus.datastore.enabled to true (required to use the PostgreSQL database).
4. Set replicas to 1 in the deployment.yml or using the kbectl.

Non-Container-Based Instructions

1. Stop Nexus Repository instances.
2. In the $data-dir/sonatype-work/nexus3/etc/nexus.properties file for the instance, turn back on, set the nexus.datastore.clustered.enabled to false.
3. In this same instance, set nexus.datastore.enabled to true (required to use the PostgreSQL database).
4. Start the Nexus Repository instance.
