Is anyone using Bootleg for deployment instead of Edeliver?

Questions / Help
6

I initially went for edeliver, but if I remember correctly I had an issue or two and I didn’t quite feel comfortable with it, so I’ve since moved to using a bash script I wrote (below in case it’s of any use - I hope I’m not embarrassing myself too much!) that runs Distillery which I run from my workstation and which is enough for my simple needs at the moment. So far I’m only using one server per app.

I’m one of those people @bitwalker mentions who isn’t comfortable with containers. I do plan to look at Bootleg at some point.

build_and_deploy_release.sh:

#!/usr/bin/env bash

# Usage: ./build_and_deploy_release.sh app version environment
# Usage example: ./build_and_deploy_release.sh my_app 0.0.1 prod

# Set to exit on error
set -ue -o pipefail

# Ensure the present working directory is that of the script
cd "${0%/*}"

# Source required functions
. $HOME/sh_scripts/functions/ask.sh

# Check for correct number of command line arguments
if [[ $# -ne 3 ]] ; then
	echo "Usage: $0 app version environment"
fi

app="$1"
version="$2"
environment="$3"
releases_dir="_build/prod/rel/${app}/releases"
archive="${app}.tar.gz"

case $app:$environment in
	app_name:prod)
		server="example.com"
		sudo_ssh_profile="user@${server}"
		app_ssh_profile="app-name@${server}"
		;;
	app_name:staging)
		server="staging.example.com"
		sudo_ssh_profile="user@${server}"
		app_ssh_profile="app-name@${server}"
		;;
	*)
		echo "No server found for ${app} at ${environment}"; exit 1 ;;
esac

if ask "Build release of ${app} ${version} for ${environment}?" ; then
	MIX_ENV=prod mix release --profile=${app}:${environment}
else
	exit 1
fi

if ask "Copy release archive to ${app_ssh_profile} and extract?" ; then
	# Copy the release archive to the server
	scp -q "${releases_dir}/${version}/${archive}" "${app_ssh_profile}:~/app/"
	# Extract and delete the release archive on the server
	ssh -qt "${app_ssh_profile}" "tar -C ~/app -xzf ~/app/${archive} && rm ~/app/${archive}"
else
	exit 1
fi

if ask "Restart ${app} app at ${app_ssh_profile}?" ; then
	echo "Restarting app; provide password for sudo for ${sudo_ssh_profile}"
	ssh -qt "${sudo_ssh_profile}" "sudo systemctl restart ${app}_app.service"
else
	exit 1
fi

echo "Deployment completed"
