Docker

• Download N3DR.
• Start a Nexus3 server.
• Populate it with artifacts:

docker login localhost:8082 \
  -p $(docker exec -it nexus3-n3dr-src cat /nexus-data/admin.password) \
  -u admin && \
for d in $(seq 5); do
  docker_registry_tag=localhost:8082/repository/docker-images/utrecht/n3dr:6.${d}.0
  docker pull "utrecht/n3dr:6.${d}.0"
  docker tag "utrecht/n3dr:6.${d}.0" localhost:8082/repository/docker-images/utrecht/n3dr:6.${d}.0
  docker push localhost:8082/repository/docker-images/utrecht/n3dr:6.${d}.0
done

• Backup all artifacts.
• Start another Nexus3 server.
• Create a repository in the other Nexus3 server:

./n3dr configRepository \
  -u admin \
  -p $(docker exec -it nexus3-n3dr-dest cat /nexus-data/admin.password) \
  -n localhost:9000 \
  --https=false \
  --configRepoName docker-images \
  --configRepoType docker

• Upload the artifacts to the other Nexus3 server.
• Validate.
• Cleanup.
