# Toolchain #
|
||||
|
||||
<https://codeberg.org/distrust/toolchain>
|
||||
|
||||
## About ##
|
||||
|
||||
A library of opinionated make functions targeting projects that either need
|
||||
deterministic builds, or a shared deterministic toolchain shared across all
|
||||
who use a project.
|
||||
|
||||
A dev of a Toolchain enabled project should never need to have anything
|
||||
on their host system installed but docker, and git. Everything else will be
|
||||
provided via a Docker container.
|
||||
|
||||
Debian currently has the highest reproducibility score of any major Linux
|
||||
distribution, and as such it is the chosen base for Toolchain.
|
||||
|
||||
This was built for Distrust projects, and some of our clients. It is unlikely
|
||||
to meet the needs of everyone. We suggest including this in your project as
|
||||
a git subtree, so you can make your own changes, but also pull in changes from
|
||||
us as desired.
|
||||
|
||||
## Uses ##
|
||||
* Ensure everyone on a team is using the exact same tools
|
||||
* Ensure all releases and artifacts build hash-for-hash identical every time
|
||||
* Control supply chain security with only signed/reproducible dependencies
|
||||
|
||||
## Features ##
|
||||
* Can run a shell with all toolchain tooling in the current directory
|
||||
* Provide make functions for common tasks
|
||||
* Git clone, apply patches, etc.
|
||||
* Use a global env file as configuration
|
||||
* Hash-locking of apt dependencies from a list of top-level required packages
|
||||
* Provides release.env file with required vars to re-create old releases
|
||||
|
||||
## Requirements ##
|
||||
|
||||
* docker 18+
|
||||
* GNU Make 4+
|
||||
|
||||
## Build ##
|
||||
|
||||
### Build a new release
|
||||
|
||||
```
|
||||
make VERSION=1.0.0rc1 release
|
||||
```
|
||||
|
||||
### Reproduce an existing release
|
||||
|
||||
```
|
||||
make VERSION=1.0.0rc1 attest
|
||||
```
|
||||
|
||||
### Sign an existing release
|
||||
|
||||
```
|
||||
make VERSION=1.0.0rc1 sign
|
||||
```
