How does Synology use docker

Docker is a popular containerization technology that can help developers package and publish applications. As an excellent NAS device, Synology provides Docker support, allowing users to use this technology more conveniently. This article will introduce readers to how to use Docker in Synology.

1. Install Docker

First, we need to install Docker. In Synology's control panel, click "Package Center", then enter "Docker" in the "Search" bar at the top, search and select the "Docker" package, click the "Install" button on the right, and wait for the installation to complete. .

2. Configuring Docker

After the installation is completed, we enter the home page of "Docker", select "Network" in the left menu, and click the "Create" button. In the pop-up "Create Network" window, enter the network name and network segment, and then click the "Apply" button to save the settings.

3. Download the image

Docker relies on images to run containers, so we need to download the required images first. You can use the "docker pull" command in the terminal to download the required image. Or search and download the required image in the "Image" menu on the Docker homepage. For example, we can search for and download "WordPress" and "MySQL" images.

4. Create container

After the image download is completed, we can start creating the container. On the Docker homepage, select the "Container" menu and click the "Create" button. First, we need to select the required image and name the container. Next, we need to configure the port mapping and volume mounting of the container. For example, when using "WordPress", we need to map it to the local port 80 and mount the mysql data volume. After completing the settings, click "Next" to enter the environment variable setting page. Here, we need to enter the WordPress database connection information. After completing the settings, click the "Apply" button to save the settings.

5. Start the container

After the container is created, we can see the status of the container in the "Container" menu. We need to start it by clicking the "Start" button on the right. After successful startup, we can enter "localhost:80" in the browser to access WordPress.

6. Manage containers

When using Docker, we need to manage the containers. For example, we can view the container's logs, attach the terminal to the container, stop the container, etc. In the "Container" menu, we can see the status of all containers. Click the corresponding container to enter the details page. Here we can perform various operations. For example, in the WordPress container details page, we can view its logs, open a terminal, stop/restart the container, etc.

Summary

Through the above steps, we can quickly use Docker on Synology and easily practice containerization. Of course, this is just a simple example, and Docker's capabilities are much more than that. I hope that through this article, I can help more people use Docker to conveniently manage and deploy the required applications.
