Meet Docker, the heart of modern DevOps processes. Eka Sunucu high performance VDS servers on, isolated, safe and deploy scalable container architecture in minutes.
Rootless mode, Docker Compose V2 and advanced security in 2026 standards Carry your projects into the future with optimizations. Automation systems such as WordPress, Laravel or n8n Manage with a single command.
Although Docker is much lighter than virtualization technologies, it is Correct resource planning is essential for the performance of applications (WordPress, MySQL, Redis, etc.). 2026 year Minimum recommended configuration as of:
Ubuntu 22.04 LTS or 24.04 LTS (Recommended). Debian 12 Stable is also an excellent alternative.
Minimum 2 vCPU. Multi-core performance is important for Docker daemon and container orchestration.
Minimum 2 GB RAM. 4 GB and above are recommended for database services and modern web applications.
NVMe SSD technology. High I/O speed is critical for Docker images and volumes.
Instead of Ubuntu repositories, Docker's official GPG key for always the most up-to-date version and We will use its repository. Please follow the steps below in order.
Before starting the installation, update existing packages and avoid conflicts.
Install the necessary tools for repo access over HTTPS.
Introduce the official Docker GPG key to the system for secure installation.
Add the repository to the source list:
Finally, update the repo list and install Docker and its plugins.

Docker is a powerful tool not only for developers but also for system administrators and digital agencies. presents. You can run dozens of different services isolated on a single VPS.
Ultra-fast WordPress sites by running Nginx, PHP-FPM, MySQL and Redis in separate containers install.
Set up your own n8n server to automate your workflows. Protect your data privacy.
You can use databases such as PostgreSQL, MongoDB or Elasticsearch as containers without installing them on the system. run it.
Define automatic SSL certificates for all your domains with Traefik or Nginx Proxy Manager.
A single container is rarely sufficient. You usually need a web server and a database.
Docker Compose combines multiple containers into a single YAML It allows you to manage the file.
Below is an example WordPress + MySQL There is an installation file:
To run this structure, you just need to give the following command:
Containers are temporary. When you delete a container, the data in it is also deleted. database To prevent your files from being lost (as in the example above), be sure to Docker Volume or Binding Mount you should use
In this way, even if you reinstall the server, your data will remain intact. /var/lib/docker/volumes safe under
remains.
Nowadays, when cyber security threats increase, just installing Docker is not enough. As Eka Sunucu We strongly recommend that you take the following safety precautions:
Do not open unnecessary ports to the outside world. You can use database ports (e.g. 3306) only on the internal network.
(127.0.0.1) or use Docker network.
Only images labeled "Official Image" or "Verified Publisher" on Docker Hub use it. Images from unknown sources may contain malware.
In your Compose file to prevent a container from consuming all the server's RAM deploy: resources: limits define.
Keep your containers up to date with tools like Watchtower. Older versions have known vulnerabilities can accommodate.
The commands you will need most in daily use:
Questions about using Docker and VPS.
No, on the contrary. Docker does not run a separate operating system kernel like virtual machines. shares the core of the server. Therefore, overhead is very low and native performance is very low. It is close.
Docker volumes are usually /var/lib/docker/volumes is kept under. backup this folder
or use bind mount to mount the data /home/user/data Link this folder to a folder like
Backing up is the most common method. You can back up these directories automatically with the Eka Sunucu JetBackup service.
Portainer is a great tool that allows you to manage Docker from the web interface instead of the terminal. Especially It provides visualization, log tracking and easy management for those who are not familiar with the command line. Docker installed It can be installed on VPS with a single command.
