Delete all SSM parameters starting with /XYZ:

aws ssm get-parameters-by-path --path /XYZ --recursive --query 'Parameters[].[Name]' --output text | xargs -n1 -IParam aws ssm delete-parameter --name Param

Context

I need to edit a file in a Docker container. This container does not have vi or an actual editor. I cannot install anything. I don't have access to run chown either.

Solution

Login on the Docker host
Get the file from the container: docker cp b28b1d60e423:/the/file/that.I.want.json .
Get into the container and find out what is the UID/GID which you want to create the file with (use id)
Edit the file on the Docker host
