Today’s topic is how to install Docker. Installing Docker also allows for VPS container-based virtualization, which is a more secure approach than traditional virtualization methods. VPS will also increase the performance of Docker containers. Additionally, with Docker VPS, you can share an image of your application with other servers that have Docker installed. Below, you can see other notable benefits of Docker VPS:
- A specific environment is provided for local development
- You can ensure that your development environment is reproduced when code is deployed, with 100% compatibility.
- Run multiple applications on the same VPS without interacting with each other.
- If a container crashes, there is no harm to the health of other containers or the VPS
- Improve security by separating different applications into their specific containers
- Provide hassle-free backups
Now, it should be clear that a container-powered VPS can provide a variety of worthwhile solutions for users. So, let’s see how we can set up a Docker VPS without any further delay.

Testing Docker Installation
Docker’s developers recommend that users check the Docker installation on the VPS with a simple hello world command by entering the following in Terminal:
sudo docker run hello-world
If everything works fine, you should see the output below:
Applying the post-installation configuration
After the installation process, it is recommended to perform some configurations. These quality-of-life improvements will make Docker more user-friendly.
- Allow Docker to run automatically after reboot
- Allow non-root users to access docker
- Install docker-compose
Hopefully, by following the steps mentioned above, you have successfully installed a Docker VPS. Now, it’s time to run Docker on your VPS and make the most of it. If you want to know how to setup webmin on a VPS?
