• nocopy

The nocopy modifier is for when you are creating a volume and data already exists in the container's path, you can specify if you want that data copied when the volume is created.

parse.sh

#!/bin/sh
buffer=$(cat)

name=$(echo $buffer | jq -r '.source.name')
surname=$(echo $buffer | jq -r '.source.surname')

echo "Hello ${name}, ${surname}"

$ openssl enc -aes-256-cbc -in un_encrypted.data -out encrypted.data
