How to present the memory of a docker container
Introduction
When we use docker, we often encounter that the memory used by the docker container is larger than the memory of the docker host, which will cause the host to crash, resulting in shutdown, which can be prevented by limiting the container memory.
Command Line
Start the hello-world container and limit the memory size to 1g
docker run -d --name hello-world --memory 1G hello-world
Parameter
| parameter | Introduction |

| --name | Assign a name to the container. |
| --memory | Memory limit. |
