How to use docker in Synology
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.
- 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. .
- 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.
- 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.
- 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.
- 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.
- 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.

Docker is a must-have skill for DevOps engineers. 1.Docker is an open source containerized platform that achieves isolation and portability by packaging applications and their dependencies into containers. 2. Docker works with namespaces, control groups and federated file systems. 3. Basic usage includes creating, running and managing containers. 4. Advanced usage includes using DockerCompose to manage multi-container applications. 5. Common errors include container failure, port mapping problems, and data persistence problems. Debugging skills include viewing logs, entering containers, and viewing detailed information. 6. Performance optimization and best practices include image optimization, resource constraints, network optimization and best practices for using Dockerfile.

DockerVolumes ensures that data remains safe when containers are restarted, deleted, or migrated. 1. Create Volume: dockervolumecreatemydata. 2. Run the container and mount Volume: dockerrun-it-vmydata:/app/dataubuntubash. 3. Advanced usage includes data sharing and backup.

Docker security enhancement methods include: 1. Use the --cap-drop parameter to limit Linux capabilities, 2. Create read-only containers, 3. Set SELinux tags. These strategies protect containers by reducing vulnerability exposure and limiting attacker capabilities.

Using Docker on Linux can improve development and deployment efficiency. 1. Install Docker: Use scripts to install Docker on Ubuntu. 2. Verify the installation: Run sudodockerrunhello-world. 3. Basic usage: Create an Nginx container dockerrun-namemy-nginx-p8080:80-dnginx. 4. Advanced usage: Create a custom image, build and run using Dockerfile. 5. Optimization and Best Practices: Follow best practices for writing Dockerfiles using multi-stage builds and DockerCompose.

Docker provides three main network modes: bridge network, host network and overlay network. 1. The bridge network is suitable for inter-container communication on a single host and is implemented through a virtual bridge. 2. The host network is suitable for scenarios where high-performance networks are required, and the container directly uses the host's network stack. 3. Overlay network is suitable for multi-host DockerSwarm clusters, and cross-host communication is realized through the virtual network layer.

DockerSwarm can be used to build scalable and highly available container clusters. 1) Initialize the Swarm cluster using dockerswarminit. 2) Join the Swarm cluster to use dockerswarmjoin--token:. 3) Create a service using dockerservicecreate-namemy-nginx--replicas3nginx. 4) Deploy complex services using dockerstackdeploy-cdocker-compose.ymlmyapp.

The core of Docker monitoring is to collect and analyze the operating data of containers, mainly including indicators such as CPU usage, memory usage, network traffic and disk I/O. By using tools such as Prometheus, Grafana and cAdvisor, comprehensive monitoring and performance optimization of containers can be achieved.

To get the Docker version, you can perform the following steps: Run the Docker command "docker --version" to view the client and server versions. For Mac or Windows, you can also view version information through the Version tab of the Docker Desktop GUI or the About Docker Desktop menu.
