How to Use a Docker Container Inside of a VPS
Docker is a platform for developing, shipping, and running distributed applications. It allows you to package your application and its dependencies into a container, which can then be deployed to any host that has Docker installed. This makes it easy to move your application from one environment to another, and it also helps to ensure that your application will run consistently on different hosts.
To use a Docker container inside of a VPS, you will need to first install Docker on your VPS. Once Docker is installed, you can then pull a Docker image for the application that you want to run. A Docker image is a compressed file that contains the application's code, its dependencies, and its configuration files. You can find Docker images for a variety of applications on the Docker Hub website.
Once you have pulled a Docker image, you can then create a Docker container from that image. A Docker container is a running instance of an application that is isolated from other applications on the same host. You can create a Docker container using the docker run
command. The docker run
command takes the name of the Docker image as its first argument, and it takes a number of other arguments that specify the settings for the container.
Once you have created a Docker container, you can then start the container using the docker start
command. Once the container is started, you can then access the container's shell using the docker exec
command. This allows you to run commands inside of the container.
Here are the steps to use a Docker container inside of a VPS in more detail:
- Install Docker on your VPS.
- Pull a Docker image for the application that you want to run.
- Create a Docker container from the image.
- Start the container.
- Access the container's shell.
sudo apt-get update sudo apt-get install docker.io
docker pull
docker run -it --name
docker start
docker exec -it/bin/bash
Once you are inside the container's shell, you can then run any commands that you need to run to configure and start your application. You can also use the docker logs
command to view the logs for the container.
When you are finished using the container, you can stop it using the docker stop
command and remove it using the docker rm
command.
docker stopdocker rm
Docker is a powerful tool that can be used to easily deploy and manage applications on a VPS. By following the steps above, you can use Docker to run any application that you need inside of a VPS.
