Enter the container name in the Name column;
Enter the container image name in the Image column. For example, if you want to install wordpress, enter wordpress, and the system will automatically pull the wordpress container image;

Set the port. If the Publish all exposed ports switch is enabled, the system will randomly open a port to map to the container port.

In addition, you can click map additional port to add a custom port (it should be noted that host can enter any non-conflicting port, and container needs to enter the corresponding port according to the specific container image. Fill in 80 here);

The host corresponds to the server port, so it is necessary to ensure that the security group opens the port
If you don't know the port of the container image, you can check it on the DockerHub website according to the type of container image you use.

Click Restart policy to select Always, which means that the container will automatically restart no matter under what circumstances it stops;
Click Deploy the container to create the container;
