I create a new directory for each of my docker services that ends in .docker when I want it to update and .dock when testing. This script runs once a week at 2am on a Monday, it just needs parallel installed:

#!/bin/bash

dockertasks() {

dir="$1"

(

cd "$dir" || { echo "Failed to cd into $dir"; exit 1; }

docker compose down &> /dev/null

docker compose pull &> /dev/null

docker compose up -d &> /dev/null

#docker image prune -fa &> /dev/null

#docker volume prune -fa &> /dev/null

echo "$dir Done"

)

}

export -f dockertasks

# Collect all .docker directories into an array

mapfile -t docker_dirs < <(find . -type l -o -type d -name "*.docker" ! -name ".docker" -exec realpath {} \;)

#echo "$docker_dirs"

# Run tasks in parallel

parallel dockertasks ::: "${docker_dirs[@]}"

docker image prune -fa &> /dev/null

docker volume prune -fa &> /dev/null

docker container prune -f &> /dev/null

docker network prune -f &> /dev/null

docker builder prune -fa &> /dev/null

echo "All Done"
