Nexus Installation Guide - Docker

Install and configure Docker

Install lxc-docker according to docs.

• Suggest using sudo instead of adding yourself to the docker group as suggested here: dial unix /var/run/docker.sock: permission denied_ issue.

Steps

Use a data volume container for persistence.

sudo docker pull sonatype/nexus
sudo docker run -d --name nexus-data sonatype/nexus echo "data-only container for Nexus"
sudo docker run -d -p 8081:8081 --name nexus --volumes-from nexus-data --restart=on-failure:10 sonatype/nexus

• TODO Evaluate how to restart nexus at boot.

  • https://docs.docker.com/articles/host_integration/

• Follow the Post-Install Checklist
