+## compose-deploy
+A simple script to update the docker compose file on a remote host and restart the containers.
+
+I created this script to suit my personal requirements, which were:
+* authenticate with the remote host using ssh keys
+* use a git repository to store the file and pull on the host
+* having one docker compose file for all the services
+
+If you want to use it, create a .env file and add the following
+
+The host of the remote server
+
+`CD_HOST=1.1.1.1`
+
+The username for the remote server
+
+`CD_USER=asher`
+
+To run the script, simply execute the script, it uses [gum](https://github.com/charmbracelet/gum) for an interactive prompt for the commit message
+
+`./redeploy.sh`
+
+Make sure your private key is in the repo and please, please make sure it is in your gitignore.
