How to Install Docker on a Server
If you’re looking to streamline your software development process and increase efficiency, installing Docker on your server is a great way to achieve that. Docker allows you to create, deploy, and manage applications in containers, isolated from each other and from the underlying infrastructure.
Here’s a step-by-step guide on how to install Docker on a server:
Step 1: Update the Server
Before you start installing Docker, it’s important to ensure that your server is up to date. You can do this by running the following commands:
sudo apt update
sudo apt upgrade
Step 2: Install Docker
Once your server is updated, you can proceed to install Docker. Run the following command to install Docker on your server:
sudo apt install docker-ce
This command will install the Docker Community Edition (CE) on your server. After the installation is complete, you can start the Docker service by running the following command:
sudo systemctl start docker
Step 3: Verify the Installation
To verify that Docker has been successfully installed on your server, you can run the following command:
docker --version
If you see the version of Docker installed on your server, then the installation was successful.
Step 4: Manage Docker as a Non-root User
By default, Docker can only be run as a root user, which can be a security risk. To run Docker as a non-root user, you can add your user to the docker group by running the following command:
sudo usermod -aG docker $USER
After running this command, you will need to log out and log back in for the changes to take effect.
Step 5: Start Using Docker
Now that Docker is successfully installed on your server, you can start using it to create and deploy containers for your applications. Docker provides an efficient and lightweight way to manage your development environment and streamline your workflow.
With Docker, you can easily package your applications and all of their dependencies into containers, allowing you to deploy them anywhere with ease. This makes it a powerful tool for developers looking to simplify the deployment process.
So, go ahead and install Docker on your server today to take advantage of all the benefits it has to offer!
