• Generate self-signed certificates

# Generate signatures to the conf.d directory for Nginx, execute the following command in the conf.d directory at the parent directory with

# Create self-signed certificate keyfile
openssl genrsa - out conf.d/ca. ey 2048
# Create a self-signed certificate crt note that in the docker-registry.iuin.xyz field the docker-registry.iuin.xyz is changed to repository name
opensl req -x509 - new -nodes -key conf. /ca.key -subj "Docker-registry.iuin.xyz" -days 5000 -out conf.d/ca.crt
# Set self-signed certificate
mkdir -p /etc/docker/certs/certs.d/docker-registry.iuin.xyz
cp conf.d/ca.crt /etc/docker/certs/certs.d/docker-registry.iuin.xyz

• Test

docker push busybox
docker tag busybox:latest docker-registry.iuin.xyz/busybox:1.0
docker push docker-registry.iuin.xyz/busybox:1.0
