python commit and push to git in Jenkins

Posted on by

I’ve looked all over the internet and can’t find anything regarding pushing to a remote repo via python…. particularly in Jenkins where your upstream is not set.

So I finally found the only helpful link and it was saying: don’t use gitpython.

But after trying multiple methods, I finally got this working. Note: It uses a few args from Jenkins && the point of this script is nothing more than to modify a file and commit it. With this functionality, I can now do real work.

import git
import os
import time
import yaml
import sys
import re
from git import Repo
print os.environ["GIT_BRANCH"]
workspace=os.environ['WORKSPACE']
m = re.search("origin/(.*)", os.environ["GIT_BRANCH"])
if m:
    git_branch = m.group(1)
else:
    sys.exit("COULD NOT LOAD SOURCE BRANCH")
# UPDATE VERSION FILE
with open(workspace + '/deploy_automation/config/int/versions.yaml', 'r') as f:
    versions_yaml = yaml.load(f)
versions_yaml["a.component"] = time.time()
with open(workspace + '/deploy_automation/config/int/versions.yaml', 'w') as f:
    yaml.dump(versions_yaml, f, default_flow_style=False)
# OTHER WAY
git_repo = Repo(workspace + "/deploy_automation")
git_repo.git.status()
git_repo.git.add(workspace + '/deploy_automation/config/int/versions.yaml')
git_repo.git.config('--global', "user.name", "user name")
git_repo.git.config('--global', "user.email", "user@domain.com")
git_repo.git.status()
git_repo.git.commit(m=' DEPLOY SCRIPT Updating versions.yaml for ENV jamestest2 and Service test')
git_repo.git.push('--set-upstream', 'origin', git_branch)

I need to configure Jenkins jobs, which are currently configured to run anywhere to work on a specific label. Sure I could do it via the gui but in a SOA, I don’t want to manually do this in 100+ jobs.

So the files currently has in it:


   </scm>
   <canRoam>true</canRoam>
   <disabled>false</disabled>



I want it to be:


   </scm>
   <canRoam>false</canRoam>
   <disabled>false</disabled>



I run:


server:~/jenkins/jobs> perl -pi -e 'BEGIN{undef $/;} s/<\/scm>.+?true<\/canRoam>/<\/scm>\nbuild<\/assignedNode>\nfalse<\/canRoam>/smg' app*/config.xml



Many thanks to aks and StackOverflow for the help

One thing I missed when moving to osx was the rename cmd. Sure you can you mv but when I’m dealing with thousands of files, rename makes it much easier.


To get it on mac, all you need is 


    

  1. Install Homebrew
    2. 

  2. Install rename

    brew install rename 

    

    3. 



That simple!!!
