Install Docker Registry V2, NGINX authentication & JOXIT UI


Docker – is a set of platform as a service products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels

Nginx – A web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. used for HTTP / HTTPS Authentication

Joxit –  This project aims to provide a simple and complete user interface for your private docker registry. You have the choice between two versions, the standard interface and the static interface.

Installation Steps

Install Docker Registry as provided in the forum posts


Generate SSL Certificates

openssl req -newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key -x509 -days 365 -out certs/domain.crt

Add your SSL created keys to docker configuration

echo “{” >> /etc/docker/daemon.json
echo ” \”insecure-registries\” : [\”$OFFLINE_REPOSITORY\”]” >> /etc/docker/daemon.json
echo “}”
mkdir /etc/docker/certs.d/
cp certs/domain.crt /etc/docker/certs.d/\/ca.crt
openssl s_client -showcerts -connect $OFFLINE_REPOSITORY < /dev/null | sed -ne ‘/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p’ > /etc/docker/certs.d//$OFFLINE_REPOSITORY/ca.crt


Install NGINX for docker authentication

Download the configuration file attached to the post and rename it to nginx.conf

Create a password file auth/nginx.htpasswd for “testuser” and “testpassword”.

docker run –rm –entrypoint htpasswd registry:2 -Bbn user pass> auth/nginx.htpasswd

if you get any error just generate htpasswd file and add it to your docker machine

htpasswd -c nginx.htpasswd username

(enter password when prompt )

Create Auth directory and copy the certificate files

mkdir auth
cp domain.crt auth
cp domain.key auth

create docker-compose.yml file with nginx settings

# Note : Only nginx:alpine supports bcrypt.
# If you don’t need to use bcrypt, you can use a different tag.
# Ref.
image: “nginx:alpine”
– 5043:443
– registry:registry
– ./auth:/etc/nginx/conf.d
– ./auth/nginx.conf:/etc/nginx/nginx.conf:ro

image: registry:2
– ./data:/var/lib/registry

run the docker compose in the same directory

docker-compose up -d

Install Joxit UI for docker registry

docker pull joxit/docker-registry-ui:latest
docker run -d -p 8080:8080 joxit/docker-registry-ui


To test your registry push and pull docker images

docker login -u=user -p=pass
docker tag ubuntu
docker push
docker pull


Login to Joxit Registry UI using your favorite browser on port 8080
