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

VAULT=<your vault here>
for ARN in $(aws backup list-recovery-points-by-backup-vault --backup-vault-name "$VAULT" --query 'RecoveryPoints[].RecoveryPointArn' --output text --region eu-west-1 --by-created-before 1672580151); do
  echo "deleting $ARN"
  aws backup delete-recovery-point --recovery-point-arn $ARN --region eu-west-1 --backup-vault-name "$VAULT"
done

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

ojacques

Export all AWS SSM Parameters retrieved from a given path as environment variables

Example:

I have the following SSM parameters:

• /codepipeline/deploy_prod with value "v1.2.0"
• /codepipeline/deploy_preprod with value "v1.1.1"
• /codepipeline/deploy_sandbox with value "a0582a5fa7fff7361b18581d04d222a35cceb264"

The following environment variables will be exported:

Use case

Filming with GoPro with H.265, but editing with software which does not support H.265 (like Magix FastCut). Let's convert all those files to H.264, leveraging GPU (like NVidia RTX 3070 -> ~2x speed at 4K->4K)

One liner

for f in *.MP4; do ffmpeg -hwaccel cuvid -i "$f" -map 0 -c copy -c:v h264_nvenc -qp 20 -tune hq -crf 25 -preset slow h264vids/"${f%.*}.mp4"; done
