Set Up nexus

1. Build Server VM. Ubuntu-Docker Image. 4 CPU / 8 GB RAM / 160 GB store
2. Build client VM. Docker image . Bare bones.
3. Open additional fire wall rules for basic usage and for mor advanced.

ufw allow 8081/tcp ufw allow 8082/tcp ufw allow 9443/tcp

Create runtime account useradd nexus mkdir /home/nexus chown nexus /home/nexus usermod -aG docker nexus

Then su - nexus To get to where you need to go.

mkdir nexus-data docker volume create --name nexus-data docker run -d -v nexus-data:/nexus-data -p 8081:8081 -p 8082:8082 -p 9443:9443 --name nexus sonatype/nexus3

To debug / retrieve the default admin password. docker exec -it {image-name} /usr/bin/bash

At this stage the nexus image should be available and you can

1. Log in
2. Add group and proxy as per the image.
3. Add docker security realm.
4. Add anon user
5. Add default local accounts.

Then a client needs modification. 1 useradd docker-client 9 usermod -aG docker docker-client

Edit the docker daemon file cat /etc/docker/daemon.json { "insecure-registries": ["138.68.228.92:8082"], "registry-mirrors": ["http://138.68.228.92:8082"] } service docker restart

http://138.68.228.92:8081/repository/docker-hub/v2/library/hello-world/manifests/latest

Should be able to force the proxy to work at this point http://138.68.228.92:8081/repository/docker-hub/v2/library/hello-world/manifests/latest and see images load and docker pull 138.68.228.92:8082/library/hello-world:latest Should work

docker login 138.68.228.92:8082

Should work.

Only down side with this is commns won't be encrypted and this needs to be reflected in the SOA
