There are alot of image registries when we are talking about docker images, such as Quay, Docker Hub, or Nexus. And on this writing, we are trying to create a docker image repository by using Nexus.
Lets start by installing Nexus to our system,
docker run -d -p 8081:8081 -p 7000:7000 --name nexus sonatype/nexus3
After logging in by using admin credentials, and yes we need to read the generated password which is located at
/nexus-data/admin.password, we need to update our admin password and after that we can create a new docker image repository.
we can test login to our Nexus image repository by using below docker command,
$ docker login localhost:7000
try pulling a new image from external, and push it into our newly created Nexus
$ docker pull alpine Using default tag: latest latest: Pulling from library/alpine 59bf1c3509f3: Pull complete Digest: sha256:21a3deaa0d32a8057914f36584b5288d2e5ecc984380bc0118285c70fa8c9300 Status: Downloaded newer image for alpine:latest
tag it, and push into Nexus image repository,
$ docker tag alpine localhost:7000/dev/alpine $ docker push localhost:7000/dev/alpine
