git distributed update

git-distributed-update.md

create bare repo and workdir on master and slaves

cd ~
git init --bare projectname.git
mkdir projectname

create post-receive hooks on each slave

vim projectname.git/hooks/post-receive

with the following content

#!/bin/bash
WORK_DIR=/path/to/workdir
WORK_BRANCH=production

while read oldrev newrev refname
do
    branch=$(git rev-parse --symbolic --abbrev-ref $refname)
    if [ "$WORK_BRANCH" == "$branch" ]; then
        GIT_WORK_TREE="$WORK_DIR" git checkout $WORK_BRANCH -f
    fi
done

change hook permission

sudo chmod +x projectname.git/hooks/post-receive

create the same hook on master with the following content(remember to change permission)

#!/bin/bash
WORK_DIR=/path/to/workdir
WORK_BRANCH=production

while read oldrev newrev refname
do
    branch=$(git rev-parse --symbolic --abbrev-ref $refname)
    if [ "$WORK_BRANCH" == "$branch" ]; then
        GIT_WORK_TREE="$WORK_DIR" git checkout $WORK_BRANCH -f
        # add this
        git push --force origin $WORK_BRANCH
    fi
done

run the following commands on master to add push remotes for each slave

# add remote
git remote add origin username@hostname1:projectname.git
# add push, don't forget the remote we just added
git remote set-url --add --push origin username@hostname1:projectname.git
git remote set-url --add --push origin username@hostname2:projectname.git
git remote set-url --add --push origin username@hostname3:projectname.git

add master to your local machine's remotes

git remote add dist username@hostname:projectname.git

push to master and let master handle the rest for you

git push dist production
