How to pause Docker containers?

To pause a Docker container, you can use the docker pause command followed by the name or ID of the container you want to pause. Pausing a container suspends all processes within it, effectively freezing its state.

Here’s how to do it:

List Running Containers: First, you may want to see which containers are currently running. Use the following command:
```
docker ps
```
Pause a Specific Container: Once you have the container name or ID, you can pause it with:
```
docker pause <container_name_or_id>
```
For example:
```
docker pause my-nginx
```
Unpause a Container: To resume a paused container, use the docker unpause command:
```
docker unpause <container_name_or_id>
```

Pausing is useful for temporarily halting a container without stopping it, allowing you to quickly resume its operation later. Let me know if you have any more questions!
