Create your own private registry and access is via UI

Step 1

Install Docker and Docker Compose

You can use this link if your sever is ubntu 20.04 as mine is:
https://support.netfoundry.io/hc/en-us/articles/360057865692-Installing-Docker-and-docker-compose-for-Ubuntu-20-04

Step 2

Create "registry:2 container

mkdir docker_registry
cd docker_registry

Create and edit "docker-compose.yml" file

nano docker-compose.yml

Please change the username and password before run the containers.

cat << EOF > docker-compose.yml
version: '3'
services:
    docker-registry:
        image: registry:2
        volumes:
        - "/tmp/docker_registry:/var/lib/registry"
        ports:
        - "5000:5000"
        restart: always
    docker-registry-ui:
        image: parabuzzle/craneoperator:latest
        ports:
        - "8086:80"
        environment:
        - REGISTRY_HOST=docker-registry
        - REGISTRY_PORT=5000
        - REGISTRY_PROTOCOL=http
        - SSL_VERIFY=false
        - USERNAME=admin
        - PASSWORD=mypassword
        restart: always
        depends_on:
        - docker-registry
EOF

Build and run the containers using below command:
docker-compose up -d

Step 3

Test registry

Pull an image you wan to push: (do this step on your registry server)
docker pull ubuntu:latest
docker tag ubuntu:latest 127.0.0.1:5000/ubuntu:latest
docker push 127.0.0.1:5000/ubuntu:latest

Step 4

Test registry from remote server (gitlab runner in my case)

docker login public-or-private-IP-of-Registry-Server:5000

Enter the "username" and "Password" you provided in Step 2.

docker pull 127.0.0.1:5000/ubuntu:latest

Also you can set this configuration at "Gitlab CICD" yml file.

P.S: If you face the error "http: server gave HTTP response to HTTPS client Error" when youwant to execute "Docker login" command plese do this on remote:
vi /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd --insecure-registry public-or-private-IP-of-Registry-Server:5000
systemctl daemon-reload
service docker restart

You can login the registry UI using http://public-or-private-IP-of-Registry-Server:8086/
