Advantages of Reproducible Builds
- Reproducible, that's a win in itself.
- You avoid polluting your environment.
- Your build environment is consistent.
How are Reproducible Builds Made
- snap
- snapcraft
- lxd
Examples of building via LXD containers
Ensure Snap is installed and Running
sudo systemctl start snapd
Installing LXD
sudo apt-get install lxd
Configuring LXD
sudo lxc init
You'll be prompted with setup questions, I recommend keeping the defaults.
Starting a Build via LXD
snapcraft cleanbuild
cleanbuild will automatically setup a new lxd container to execute your build. This makes for a completely clean build of your application.
snapcraft cleanbuild --debug
The following command will build the package in container and remain on failure. This gives you the opportunity to test and debug your build in a bash shell.
