Use an Alibaba Cloud Linux image in Docker

Create a Docker container from an Alibaba Cloud Linux image

1. Install and use Docker and Docker Compose.

2. Pull an Alibaba Cloud Linux Docker image.

   sudo docker pull alibaba-cloud-linux-<image_version>-registry.<region_ID>.cr.aliyuncs.com/alinux<image_version>/alinux<image_version>:<TAG>

   • <image_version>: The version of Alibaba Cloud Linux, such as 2 or 3.

   • <region_ID>: The ID of the image's region, such as cn-hangzhou.

   • (Optional) <TAG>: The Docker image tag. Defaults to the latest version if omitted.

   Find image region and tag information

   1. Go to Container Registry - Artifact Center.

   2. Click alinux2/alinux2 or alinux3/alinux3 to view the Docker image tag information for Alibaba Cloud Linux 2 and Alibaba Cloud Linux 3.

      For example, the following figure shows Alibaba Cloud Linux 3 Docker image details. ① indicates the image region, and ② indicates the image tags.

      

   Sample commands:

   • Pull the 220901.1 tag of the Alibaba Cloud Linux 3 Docker image in the cn-hangzhou region.

     sudo docker pull alibaba-cloud-linux-3-registry.cn-hangzhou.cr.aliyuncs.com/alinux3/alinux3:220901.1

   • Pull the latest Alibaba Cloud Linux 2 Docker image in the cn-hangzhou region.

     sudo docker pull alibaba-cloud-linux-2-registry.cn-hangzhou.cr.aliyuncs.com/alinux2/alinux2

3. Verify the image pull.

   sudo docker images

   The output confirms that the 220901.1 Alibaba Cloud Linux 3 image and the latest Alibaba Cloud Linux 2 image were pulled.

   

4. Create and enter a Docker container.

   sudo docker run -it alibaba-cloud-linux-<image_version>-registry.<region_ID>.cr.aliyuncs.com/alinux<image_version>/alinux<image_version>:<TAG> /bin/bash

   • <image_version>: The version of Alibaba Cloud Linux, such as 2 or 3.

   • <region_ID>: The ID of the image's region, such as cn-hangzhou.

   • (Optional) <TAG>: The Docker image tag. Defaults to the latest version if omitted.

   Sample commands:

   • Create a Docker container from the 220901.1 tag of the Alibaba Cloud Linux 3 image in the cn-hangzhou region.

     sudo docker run -it alibaba-cloud-linux-3-registry.cn-hangzhou.cr.aliyuncs.com/alinux3/alinux3:220901.1 /bin/bash

   • Create a Docker container from the latest Alibaba Cloud Linux 2 image in the cn-hangzhou region.

     sudo docker run -it alibaba-cloud-linux-2-registry.cn-hangzhou.cr.aliyuncs.com/alinux2/alinux2 /bin/bash

   

   Note

   • Inside the container, you can run commands at the shell prompt.

   • Run exit to leave the container.

5. (Optional) Restart and enter the Docker container.

   The exit command stops the container. Restart and re-enter it to continue using it.

   1. Find the CONTAINER ID of the created container.

      sudo docker ps -a

      The CONTAINER ID column shows the container ID.

      

   2. Start the Docker container.

      sudo docker start <CONTAINER ID>

      Replace <CONTAINER ID> with the actual ID of your Docker container.

      Run sudo docker ps to verify the container is running.

      

   3. Enter the running Docker container.

      Replace <CONTAINER ID> with the actual ID of your Docker container.

      sudo docker exec -it <CONTAINER ID> /bin/bash

      The output confirms you re-entered the container.

      

Delete a Docker container and image

Delete unused containers and images to free resources.

1. Stop the Docker container.

   Replace <CONTAINER ID> with the actual ID of your Docker container.

   sudo docker stop <CONTAINER ID>

2. Delete the Docker container.

   Replace <CONTAINER ID> with the actual ID of your Docker container.

   sudo docker rm <CONTAINER ID>

3. View all Docker containers.

   sudo docker ps -a 

   The output confirms the container is deleted.

   

4. Find the image's repository name.

   sudo docker images

   The REPOSITORY column shows the image name.

   

5. Delete the Docker image.

   Replace <REPOSITORY> with the actual name of your image.

   sudo docker rmi <REPOSITORY>

   The output confirms the image is deleted.
