Jenkins Job Builder library

This repo holds configs for jenkins jobs and some useful tools.

Using jenkins configs

Creating ini file for server with your creds

set server name to operate with

server_name="example"

Copy config and replace server address, user and password with your own

cp "./conf/jenkins_job.ini.example" "./${server_name}.ini"

Testing jobs configs

test all (useful for testing changes in commons)

tox

test just configs for particular instance

tox -e "${server_name}"

Note: tox should be installed globally

Comparing job configs before/after changes

To compare output of changed yaml configs you need to render xmls.

Let's say we are going to change something in ${pr_branch}

For existing branch

# activate venv used in test with right version of tools
source "./.tox/${server_name}/bin/activate"

# switch to current revision
git checkout master
git pull

# render current xmls
jenkins-jobs --conf "./${server_name}.ini" test "servers/${server_name}/:common" -o "./out-for-master"

# switch to existing pr/changed revision
git checkout "${pr_branch}"
git pull

or to create new branch

git checkout -b "${pr_branch}"
# .. and do some changes

# render new xmls
jenkins-jobs --conf "./${server_name}.ini" test "servers/${server_name}/:common" -o "./out-for-${pr_branch}"

# compare with diff tool

diff -r "./out-for-master" "./out-for-${pr_branch}"

Note:

• > sign means that change came from ./out-for-${pr_branch}
• < sign means that change came from ./out-for-master

Updating/adding jobs on jenkins instance.

# activate venv used in test with right version of tools
source "./.tox/${server_name}/bin/activate"
# update all jobs on server
# this will not delete any job if it is not presented in configs
jenkins-jobs --conf "./${server_name}.ini" update "servers/${server_name}/:common"
# update jobs by pattern (note single quotes): 
jenkins-jobs --conf "./${server_name}.ini" update "servers/${server_name}/:common" 'ABC-*'
# deactivate venv when finished
deactivate

Removing (deleting) jobs from jenkins instance.

# activate venv used in test with right version of tools
source "./.tox/${server_name}/bin/activate"
# this will delete job on server
jenkins-jobs --conf "./${server_name}.ini" delete "name-of-job-to-remove"
# deactivate venv when finished
deactivate
