# yoctoBuild
|
||||||
|
|
||||||
|
yoctoBuild is a bare-bones build service for your personal projects. Since many
|
||||||
|
hosted build services do not work outside of GitHub and BitBucket, this was
|
||||||
|
made to work with Gogs for light usage where hosting Jenkins would be absurd.
|
||||||
|
|
||||||
|
yoctoBuild is unaware of git, Mercurial, scss, etc. It depends on a bash
|
||||||
|
executable and proper configuration.
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
Run `yoctobuild` in its directory or copy the badges and a config file to a
|
||||||
|
working directory. Provide a `-secret` on startup, and then set your Gogs/Git
|
||||||
|
hooks/etc to send a request to `/projects/<your project>/build?secret=<your
|
||||||
|
secret>`.
|
||||||
|
|
||||||
|
The config file consists of a map of projects and their steps. The build server
|
||||||
|
does nothing but create a working directory for the build so the build steps
|
||||||
|
must check out code, perform tests, and manage any dependencies. The config
|
||||||
|
file should only be modified by owners of the server it lives on as it may
|
||||||
|
execute arbitrary commands on your behalf.
|
||||||
|
|
||||||
|
This build service is very simple. It does not watch for branches or anything
|
||||||
|
of the like. You must configure a project for each individual item that you
|
||||||
|
wish to watch.
|
||||||
|
|
||||||
|
Badges may be served by embedding `/projects/<your project>/badge` as an image
|
||||||
|
in your page.
