Docker clear cache in windows 10

General
1

Hi all. I have tried to clear cache of docker, and have used the following commands
docker kill $(docker ps -q)
docker rmi $(docker images -a -q)

but the response I have got the error look like this
unknown shorthand flag: ‘a’ in -a

2

Why not use docker system prune -a ?

I am having the exact same problem. Does anyone have a solution for this error?
I just want to STOP all containers, NOT remove them.

Thanks!

Try this command from Powershell since you are running Docker for Windows.

docker container stop (docker container ls -q) | Out-String

Example

PS C:\Users\Administrator> docker container ls
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS               NAMES

You can start them back up.

PS C:\Users\Administrator> docker container start 951fe970b796
