Docker Private Registry with Frontend UI

Hey! In this DevOps learning post, I've done my experiment on Docker Registry-Server connecting with the docker registry UI as a frontend. To support this Frontend service, we have an Apache HTTP server container used as a docker-registry-frontend image.

Docker Registry Server connect with Frontend UI

Step 1: Go to the docker hub search for 'docker-registry-frontend' given version Pull the image to your local system.

docker pull registry 
docker pull konkardkleine/docker-registry-frontend:v2 
docker images 

docker network create registry 
docker network ls

Step 2: Create the registry server using a docker container run command which expose the port as 5000 and the network that we have created in the step1. This separate network creation will be easy to isolate with other containers running on the same host.

docker run --rm -d -p 5000:5000 --name registry-server \
--network registry 
To verify the access of registry-server
docker logs registry-server -f

Step 3: You can find many other web UI options on the Docker Hub, Here I've selected the web-ui image - konradkleine/docker-registry-frontend:v2. Here we have two environment variables need to set HOST and PORT. To access this registry web page we need to open the port with -p option. 

Create the registry-ui container as follows:

docker run \
  -d --rm --name registry-ui --network registry \
  -e ENV_DOCKER_REGISTRY_HOST=192.168.33.250 \
  -e ENV_DOCKER_REGISTRY_PORT=5000 \
  -p 8080:80 \
  konradkleine/docker-registry-frontend:v2
             

Step 4: To verify the access logs of registry-ui web server run the following command:

docker logs registry-ui -f

Step 5: Open a duplicate terminal and do the following image tag to use it on our private registry.

docker tag busybox dockerhost.test.com:5000/busybox
docker images 

docker push localhost:5000/nginx

Now let's see on the browser where we can access the registry-ui which is actually running with Apache HTTPD 2 webserver

Docker Private Registry Web 

Step 6: After push you can see the images on the registry-ui same you can check with curl command as well like this:

 curl -X GET http://localhost:5000/v2/_catalog
{"repositories":["nginx"]}
