Docker Deployment

Requirements

Install Docker, to ensure you can execute docker command:

$ docker
Usage:  docker [OPTIONS] COMMAND

A self-sufficient runtime for containers

Common Commands:
  run         Create and run a new container from an image
  exec        Execute a command in a running container
  ps          List containers
  build       Build an image from a Dockerfile
  pull        Download an image from a registry
  push        Upload an image to a registry
...

docker login

Then enter your username and password to login, then you will see like:

Login Succeeded

Build with Docker

docker build -t <username>/<image> .

Replace <username> to your username in Docker Hub, and replace <image> with any name you want as the image name, like:

docker build -t foobar/hub .

Then you will see like this:

Push Docker

docker push <username>/<image>

Now you have pushed your image to Docker Hub, then you can deploy this image to any server.

Deploy Docker

In your server machine, you can then pull this image and then run it

docker run -d -p 8000:80 <username>/<image>

Then visit http://localhost:8000 you will see it.

Configure HTTPS

If you want to configure HTTPS and domain, like example.abc.com, you can install Nginx to forward the traffic from Docker:

Apply the HTTPS cert for your domain, you will have 2 files, one is cert, the other is private key, like example.abc.com.pem and example.abc.com.key, change the nginx conf file as below:

server {
    listen       443;
    server_name  example.abc.com;

    ssl_certificate /path/to/your/example.abc.com.pem;
    ssl_certificate_key /path/to/your/example.abc.com.key;

    location / {
        proxy_pass http://127.0.0.1:8000;
    }
}

Also please set the Domain to server's ip address, then restart nginx, it will work.
