Running self-hosted nexus3 as docker

Here are 2 good links to run on truenas (different approach) - I used the second one via docker compose. 1. https://blog.joeplaa.com/sonatype-nexus-oss-repository/ 2. https://medium.com/@chiemelaumeh1/install-sonatype-nexus-3-using-docker-compose-setup-nexus-repository-manager-for-node-js-project-47a3c5efe1ee

Apps missing in Truenas

What you do is to : "Unset Pool" and then "Choose Pool". The apps should re-apprear. If not, reboot the server and try again.
