Unlocking Containerization: A Guide to Using Docker VPS Templates

Docker is a containerization platform that enables the creation of consistent, isolated environments that run seamlessly across a variety of computing environments, from development to production.

a) Connect your virtual private server (VPS)

1. First, open Terminal or Command Prompt/PowerShell on your local computer and enter the ssh root@vps_ip command.

2. Then, replace vps_ip with your VPS IP address, and you may be prompted for your VPS password.

b) Check the Docker installation

1. After that, the docker –version command is used to confirm the installation of Docker, and it will provide the necessary version information if the installation is correct.

2. Next, use the docker-compose –version command to verify the version of Docker Compose.

c) Deploy your first Docker container

1. Then, pull a sample Docker image, like “Hello World”, and use the docker run hello-world command to download and run the container to test your setup.

d) Get started with Docker Compose

1. After that, create a new directory for the Docker Compose project and navigate to it using the mkdir my-docker-project and cd my-docker-project commands.

2. Once in the project directory, create a docker-compose.yml file in the project directory and define services, networks, and volumes using a text editor.

3. Next, you can start the service using the docker-compose-up -d command, which reads the configuration from the current directory. The -d flag detaches the command, running in the background and returning to the command line.

Manage the Docker Compose services

1. To stop the Docker Compose service, use the docker-compose down command.

2. To list all running containers, use the docker ps command.
