Using stop will stop the container, not pause it.

Using kill will forcefully stop the container.

The pause command suspends all processes in the container without stopping it.

💡 Hint

Common Mistakes

Using run creates a new container instead of starting the existing one.

Using exec runs a command inside a running container.

The start command resumes a stopped container. run creates and starts a new container, which is different.

Fill both blanks to create a container named 'db' from the image 'mysql' and keep it stopped after creation.

Docker

💡 Hint

Common Mistakes

Using run starts the container immediately.

Using start or db as commands is incorrect.

The create command makes a container but does not start it. The name 'db' is assigned with --name.

5fill in blank

Fill both blanks to unpause a container named 'cache' and then stop it.

Docker

docker [1] cache && docker [2] cache

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using pause instead of unpause to resume.

Using start instead of unpause for resuming a paused container.

The unpause command resumes the paused container, making it running. The stop command stops it. pause suspends a running container, and start resumes a stopped one.
