Poor Man's CI

We don't want to depend on third party services for our CI

(SERVER) Create a bare git repository in the production server

We need this in order to trigger the post-recieve hook

$ git init --bare /var/beer/ci-update-repo

(SERVER) Add the post recieve script

This can be as easy as issuing a git pull or as complex as creating packages, containers and running smoke tests.

$ cd ci-update-repo/hooks
$ cat <<EOF >> post-recieve
#!/usr/bin/sh
# Just pull on the repo
REPODIR="/var/beermasters"
cd $REPODIR
echo `date +"%m-%d-%y-%H:%m"`:"TRIGGERING POOR MAN's CI" >> $REPODIR/ci.log
git --git-dir=${REPODIR}/.git --work-tree=${REPODIR} pull -v origin master &>> $REPODIR/ci.log

EOF

(WORKSTATION) Add server bare repo as remote

$ cd git-local-repo
$ git remote add ci-repo ssh://user@remote.repo.com:1234/var/beer/ci-update-repo

(WORKSTATION) Trigger the CI

After we make changes and commit them push them to the CI

$ git push ci-repo master

Be Happy!!
