A Dockerfile for Sonatype Nexus Repository Manager 3 ready for HA.
GitHub Repository: https://github.com/bradbeck/nexus-ha
To (re)build the image:
$ docker build --rm -t bradbeck/nexus-ha .
The following only needs to be done once in order to setup the environment, i.e. create the docker volume to hold the NXRM3 license.
Create a custom docker network:
docker network create custom
Create a docker volume to store the NXRM3 license
docker volume create java-prefs
Create or recreate the docker volume used for blob storage:
docker volume create shared-blobs
Start an instance NXRM3 and upload the license
docker run --rm -p 8081:8081 -v java-prefs:/opt/sonatype/sonatype-work/nexus3/javaprefs --network custom -it bradbeck/nexus-ha
Wait for the following banner (NXRM-STARTED) in the console output before continuing to the next step:
-------------------------------------------------
Started Sonatype Nexus PRO 3.7.0-04
-------------------------------------------------
Follow the steps in "Uploading a License" for uploading the license. This will remain in the java-prefs docker volume for all of the remaining steps.
Once the license is uploaded, use Ctl-C to stop the NXRM3 container.

docker run --rm -p 8081:8081 -v shared-blobs:/opt/sonatype/sonatype-work/nexus3/blobs -v java-prefs:/opt/sonatype/sonatype-work/nexus3/javaprefs --network custom --name nexusa -h nexusa -it bradbeck/nexus-ha
Start NXRM3 nexusb node, and wait for NXRM-STARTED:
docker run --rm -p 8082:8081 -v shared-blobs:/opt/sonatype/sonatype-work/nexus3/blobs -v java-prefs:/opt/sonatype/sonatype-work/nexus3/javaprefs --network custom --name nexusb -h nexusb -it bradbeck/nexus-ha
Start NXRM3 nexusc node, and wait for NXRM-STARTED:
docker run --rm -p 8083:8081 -v shared-blobs:/opt/sonatype/sonatype-work/nexus3/blobs -v java-prefs:/opt/sonatype/sonatype-work/nexus3/javaprefs --network custom --name nexusc -h nexusc -it bradbeck/nexus-ha
