Debugging tipps when working with cloud-init

Cloud-Init Debugging

Cloud-init combined with terraform can be a powerful tool to provision instances on startup. Debugging scripts that are run by cloud-init however are not the easiest to debug.

Usually on an Ubuntu machine a lot of what is happening can be found in the syslog

cat /var/log/syslog

Update a docker stack deployment

Update Docker Stack Deployment

A docker stack deployment can be updated by re-executing the deployment command.

docker stack deploy --compose-file=[docker-compose file] [stack-name]

An example where this could be used is if the image version changed. Simply change the docker-compose configuration to the newest version and then execute the above command.
