Native packaging for Jenkins

Primary LanguageShell

Native package script for Jenkins

This repository contains scripts for packaging jenkins.war into various platform-specific native packages. The following platforms are currently supported:

  • Windows MSI: msi/
  • RedHat/CentOS RPM: rpm/
  • Debian/Ubuntu DEB: deb/
  • OpenSUSE RPM: suse/

Pre-requisites

Running the main package script requires a Linux environment (currently Ubuntu, see JENKINS-27744.) Run make setup to install (most of the) necessary tools. Alternatively you can manually install the following onto a base install of Ubuntu:

  • make
  • unzip
  • devscripts
  • debhelper
  • rpm
  • expect
  • createrepo-c
  • ruby
    • net-sftp (gem install net-sftp)
  • maven
  • java

You also need a Jenkins instance with dist-fork plugin installed. URL of this Jenkins can be fed into make via the JENKINS_URL variable. This Jenkins needs to have a Windows build agent that has WiX Toolset (currently 3.5), msbuild, cygwin and .net 2.0. This build agent is used to build MSI packages, which can be only built on Windows.

You'll also need a jenkins.war file that you are packaging, which comes from the release process. The location of this file is set via the WAR variable.

Remark:

A docker image is available to run following script

Run docker-compose run --rm packaging bash to get a shell in the official Docker image for this repository.

Generating packages

Run ./prep.sh to perform the preparatory actions of downloading the WAR and importing the GPG key. Run make package to build all the native packages. At minimum, you have to specify the WAR variable that points to the war file to be packaged and a branding file (for licensing and package descriptions). You will probably need to pass in the build environment and credentials.

For example:

make package BRAND=./branding/jenkins.mk BUILDENV=./env/test.mk CREDENTIAL=./credentials/test.mk

Packages will be placed into target/ directory. See the definition of the package goal for how to build individual packages selectively.

Running functional tests

The functional tests require Python 3 and Docker. Having built the packages as described above, run the functional tests with:

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
molecule test
deactivate

Publishing packages

This repository contains scripts for copying packages over to a remote web server to publish them. Run make publish to publish all native packages.

See the definition of the publish goal for individual package publishment.

Running local tests

These tests install packages from a web server where they are published. So if you want to run tests prior to publishing them, you need to create a temporary web server that you can mess up.

The default branding & environment (branding/test.mk and env/test.mk) are designed to support this scenario. To make local testing work, you also need to have /etc/hosts entry that maps test.pkg.jenkins.io hostname to 127.0.0.1, and your computer has to be running ssh that lets you login as you.

Once you verified the above prerequisites, open another terminal and run make test.local.setup This will run a docker container that acts as your throw-away package web server. When done, Ctrl+C to kill it.

Branding

branding/ directory contains *.mk files that control the branding of the generated packages. It also include text files which are used for large, branded text blocks (license and descriptions). Specify the branding file via the BRAND variable.

You can create your own branding definition to customize the package generation process. See branding readme for more details. In the rest of the packaging script files, these branding parameters are referenced via @@NAME@@ and get substituted by bin/branding.py. To escape a string normally like @@VALUE@@, add an additional two @@ symbols as a prefix: @@@@VALUE@@.

Environment

env/ directory contains *.mk files that control the environment into which you publish packages. Specify the environment file via the BUILDENV variable.

You can create your own environment definition to customize the package generation process. See environment readme for more details.

Credentials

credentials/ directory contains test.mk file that controls the locations of code-signing keys, their passwords, and certificates. Specify the credentials file via the CREDENTIAL variable.

For production use, you need to create your own credentials file. See credentials readme for more details.

TODO (mostly note to myself)

  • Split resource templates to enable customization
