# tci
|
||
|
|
> tiny custom CI runner for your selfhosted just-git repositories
|
||
|
|
|
||
|
|
## why
|
||
|
|
continuous integration is really convenient when you have quite some tiny projects which you'd like to keep updated.
|
||
|
|
|
||
|
|
this one has its doc page, that one compiles to a minified js file that i should serve, this one has a demo instance that i should restart...
|
||
|
|
|
||
|
|
i don't want to bother doing these things every time i write some fixes!
|
||
|
|
|
||
|
|
also, i really like the idea of keeping CI configuration committed with the repository itself
|
||
|
|
|
||
|
|
## how
|
||
|
|
git natively supports [hooks](https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks). they are extremely convenient and pleasant to use (just a shell script!), but aren't version-controlled in the repository they belong to.
|
||
|
|
|
||
|
|
i use them on my client to validate my commits and sometimes configure/cleanup projects
|
||
|
|
|
||
|
|
because i self-host my git repositories (did you know you just need to `git init --bare <name>` in your home and you can pull/push from there! `git clone <user>@<host>:<repo-path>` just works), i can't just use github/gitlab, and would rather not go mad configuring jenkins
|
||
|
|
|
||
|
|
most of my CIs are super simple: `cargo doc; cp * /srv/http/docs/`, configuring something complex like jenkins seems overkill
|
||

# introducing tci!
|
||
|
|
`tci` is a Tiny CI runner
|
||
|
|
|
||
|
|
just set it as `post-update` hook in your repository and, each time such repository gets updated, tci will:
|
||
|
|
* make sure repo is allowed to run CI: checks said repo git config for `tci.allow == true`
|
||
|
|
* create a temp dir (under `/tmp`) with unique name
|
||
|
|
* clone your repository in that dir
|
||
|
|
* change current working directory to be inside your freshly cloned repo
|
||
|
|
* run `.tci` script (you can change it by setting git config `tci.script`)
|
||
|
|
* print script's `STDOUT` to console
|
||
|
|
* delete temporary directory
|
||
|
|
|
||
|
|
and that's it! could not be simpler
|
||
|
|
|
||

|
# using tci
|
||
|
|
a very simple example: i'd like to auto-update cargo documentation for my project
|
||
|
|
|
||
|
|
first step is enabling tci for such repo: `git config tci.allow true` on my server
|
||
|
|
|
||
|
|
then i can just add a `.tci` script in the project root:
|
||
|
|
```
|
||
|
|
#!/bin/bash
|
||
|
|
|
||
|
|
cargo doc
|
||
|
|
rm -rf /srv/http/docs/*
|
||
|
|
cp ./build/* /srv/http/docs/
|
||
|
|
```
|
||
|
|
|
||
|
|
just commit and push!
|
||
|
|
|
||
|
|
### setting tci as default runner for every repository
|
||
|
|
configuring tci as post-update hook for *each repository* is definitely annoying
|
||
|
|
|
||
|
|
luckily, git allows us to configure a default hook location valid for every repository!
|
||
|
|
inside your `~/.gitconfig` just insert:
|
||
|
|
```
|
||
|
|
[core]
|
||
|
|
hooksPath = /path/to/some/directory/
|
||
|
|
```
|
||
|
|
inside such directory, place `tci` and rename it to `post-update`
|
||
|
|
|
||
|
|
and done! should enable tci for all repos (if they are configured to allow it)
