How to use Synology docker (tutorial)

In the modern technology field, Docker has become a very popular virtualization technology. By using Docker, you can create lightweight, portable containers that can hold applications, operating systems, dependencies, and more. This greatly simplifies application deployment and management, allowing developers to easily deploy applications in a variety of environments.

In response to such needs, Synology also provides Docker support, making it very simple and convenient to use Docker in Synology NAS. In the following content, we will introduce in detail how to use Docker in Synology NAS.

1. Confirm that Synology NAS supports Docker

First, we need to confirm whether Synology NAS supports Docker. After DSM version 6.0, Synology has begun to support Docker, so as long as your system version meets the requirements, you can directly perform subsequent operations. You can check your system version number in the "Package Center" in the Synology console.

2. Install Docker

After confirming that the NAS supports Docker, we need to install Docker in the NAS. By default, Docker installation is not provided in the "Package Center" of Synology NAS. We need to add it manually first.

After entering the package center, in the "Settings" option in the upper right corner, select "Package Source" and add the Docker official package library. After adding it, you can search for Docker in the package list and install it.

During the installation process, you may need to download some files from Docker's official library, so it will take some time to wait.

3. Configure Docker

After the installation is completed, we need to configure Docker. First, in the "docker" menu of the Synology console, you need to confirm the Docker network mode. By default, a bridge network is created on Synology to support communication between Docker containers.

Next, Docker needs to be configured. In the "Folder" option, we need to set the local storage path of Docker for storing container data and images, etc.

In the "Network" option, network port mapping needs to be set, so that the access policy for exposing container functions to the outside can be implemented. For example, we can map the Docker container port 80 to the host's port 8080, and open the host's 8080 port in the browser to access the Docker container's web service.

4. Using Docker

After completing the basic configuration, you can use Docker. You can obtain various container images from Docker's official warehouse and download them for use.

Create containers through mirroring in Docker. For example, we can create an nginx container through the following command:

docker run --name mynginx -p 80:80 -d nginx

Among them, the parameter "-d" means using the background mode to run the container, "-p" sets the port mapping, and "nginx" indicates the image that needs to be started.

After creation, you can check the running status of the container through the following command:

docker ps

You can also stop the running of the container through the following command:

docker stop mynginx

5. Delete Docker

If Docker is no longer needed, you can also delete it through the following command:

docker rm mynginx

Note, This will completely delete the container, including the data in the container. If you need to retain it, please back up the data before deleting it.

Summary:

Docker is a very popular virtualization technology that makes application deployment and management simple and easy to use. Synology NAS also supports Docker. Through simple configuration and use, we can easily deploy applications and experiment with various new services on it.
