⚠️ This repository is no longer in use as of Kong Gateway 3.1 - Kong is now built by Bazel, see the build/README.md file.

Kong Build Tools

The tools necessary to build, package and release Kong

Prerequisites

  • Kong source
  • Docker
  • docker-compose
  • Make

All examples assume that Kong is a sibling directory of kong-build-tools and run from the kong-build-tools directory unless otherwise specified. This behaviour can be adjusted by setting a KONG_SOURCE_LOCATION environment variable

cd ~
git clone [email protected]:Kong/kong.git
git clone [email protected]:Kong/kong-build-tools.git
cd kong-build-tools

# example of KONG_SOURCE_LOCATION usage for kong-ee
export KONG_SOURCE_LOCATION=/Users/kong/Documents/Kong-Repos/kong-ee

Packaging kong-ee additionally requires:

  • A GITHUB_TOKEN environment variable with access to Kong's private github repositories
  • git checkout to target kong-ee branch before starting.

Packaging arm64 architectures additionally requires:

Building a Kong Package

export PACKAGE_TYPE=deb RESTY_IMAGE_BASE=ubuntu RESTY_IMAGE_TAG=20.04 # defaults if not set
make package-kong
ls output/
kong-x.y.z.20.04.all.deb

Details

building kong

The Docker files in the dockerfiles directory build on each other in the following manner:

  • Dockerfile.package builds on top of the result of Dockerfile.kong to package Kong using fpm-entrypoint.sh
  • Dockerfile.kong builds on top of the result of Dockerfile.openresty to build Kong using build-kong.sh
  • Dockerfile.openresty builds on top of the result of Dockerfile.(deb|apk|rpm) to build the Kong prerequisites using openresty-build-tools/kong-ngx-build
  • github://kong/kong-build-tools-base-images builds the compilation / building prerequisites

Building a Kong Docker Image

Prerequisite: you did the packaging step

export KONG_TEST_CONTAINER_NAME=kong/kong:x.y.z-ubuntu-20.04 #default if not set
make build-test-container

Releasing Docker Images

Prerequisite: you did the packaging step and you're logged into docker with the necessary push permissions

export DOCKER_RELEASE_REPOSITORY=kong/kong KONG_TEST_CONTAINER_TAG=x.y.z-ubuntu-20.04 #default if not set
make release-kong-docker-images

Running Kong Tests

make test-kong

Environment variables:

Refer to git://kong/.ci/run_tests.sh for the authoritative environment variables. The most common ones are the following:

TEST_DATABASE = "off|postgres|cassandra"
TEST_SUITE = "dbless|plugins|unit|integration"

Details

testing kong

  • docker-compose.yml runs the result of Dockerfile.test as well as postgres, cassandra, grpc and redis
  • Dockerfile.test builds on top of the result of Dockerfile.openresty to build Kong for development/testing
  • Dockerfile.openresty builds on top of the result of Dockerfile.(deb|apk|rpm) to build the Kong prerequisites using openresty-build-tools/kong-ngx-build
  • Dockerfile.(deb|apk|rpm) builds the compilation / building prerequisites

Running Packaging / Smoke Tests

The Kong Build Tools functional tests suite run a tests on a Kong package which we then integrate into our official docker build image dockerfile.

make package-kong
make test

Details

releasing kong

test/build_container.sh clones git://kong/docker-kong and provides the Dockerfile with a packaged Kong asset

01-package

Validates the version required per git://kong/.requirements of our prerequisites is what ended up being installed. Also does some rudimentary checks of the systemd and logrotate we include with our packages

02-api

Functional Admin API and Proxy tests.

Releasing Kong

The same defaults that applied when creating a packaged version of Kong apply to releasing said package to our internal server and can be changed by environment variables. Presumes that the package you want to release already exists in the output directory.

export PULP_USR=user
export PULP_PSW=password
export RESTY_IMAGE_BASE=seeabove
export RESTY_IMAGE_TAG=seeabove
export KONG_PACKAGE_NAME=somename
make package-kong
make release-kong

Required release ENV variables:

PULP_USR
PULP_PSW
