Linux サーバー上に安全で信頼性の高い Docker イメージ ウェアハウスを構築するにはどうすればよいですか?

$ sudo apt-get update
$ sudo apt-get install docker-ce

$ docker version

$ docker run -d -p 5000:5000 --name registry registry:latest

$ curl http://localhost:5000/v2/_catalog

$ sudo apt-get install nginx

$ sudo sh -c "echo -n 'admin:' >> /etc/nginx/.htpasswd"
$ sudo sh -c "openssl passwd -apr1 >> /etc/nginx/.htpasswd"

server {
    listen 80;
    server_name <your-domain-name>;

    location / {
        proxy_pass http://localhost:5000;

        auth_basic "Restricted";
        auth_basic_user_file /etc/nginx/.htpasswd;
    }
}

$ sudo apt-get install openssl

$ sudo openssl req -newkey rsa:2048 -nodes -keyout registry.key -x509 -days 365 -out registry.crt

server {
    listen 443 ssl;
    server_name <your-domain-name>;

    ssl_certificate /path/to/registry.crt;
    ssl_certificate_key /path/to/registry.key;

    location / {
        proxy_pass http://localhost:5000;

        auth_basic "Restricted";
        auth_basic_user_file /etc/nginx/.htpasswd;
    }
}

$ sudo vi /etc/docker/daemon.json

{
    "insecure-registries": ["<your-domain-name>:5000"]
}

$ sudo systemctl restart docker

$ docker tag image <your-domain-name>:5000/image
$ docker push <your-domain-name>:5000/image
$ docker pull <your-domain-name>:5000/image
