  • In "error decoding Ports" when updating (docker-compose v1->v2 switch)

    Update docker-compose v1 to v2

    First: backup your server or take a snapshot

    Update os:
    sudo apt update && sudo apt upgrade -y

    Stop MailCow docker stack:

    cd /opt/mailcow-dockerized
docker-compose down

    Install docker-compose v2

    sudo curl -L "https://github.com/docker/compose/releases/download/v2.6.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod a+x /usr/local/bin/docker-compose
# Enable & start docker
sudo systemctl enable docker
sudo systemctl start docker

docker --version && docker-compose --version
     ./update.sh --check

 ./update.sh

    Are you sure you want to update mailcow: dockerized? All containers will be stopped. [y/N] y

    Should we try to enable the native IPv6 implementation in Docker now (recommended)? [y/N] N

    Advanced Remove old images and unused volumes
    docker system prune -a –volumes (make sure all of the container are up and running: docker-compose ps -a )

    This is how I upgraded docker-compose v2 and it worked.
