Build your own Docker images

Kong is distributed as prebuilt apk, deb and rpm packages, in addition to official Docker images hosted on DockerHub

Kong builds and verifies Debian and RHEL images for use in production. Alpine images are provided for development purposes only as they contain development tooling such as git for plugin development purposes.

Our Debian and RHEL images are built with minimal dependencies (as of Kong Gateway 3.0) and run through automated security scanners before being published. Any vulnerabilities detected in supported images will be addressed in the next available patch release.

If you would like to build your own images to further customise the base image and any dependencies, follow the instructions below:

1. Download the docker-entrypoint.sh script from docker-kong and make it executable with chmod +x docker-entrypoint.sh

2. Download the .deb, .rpm or .apk (amd64, arm64) as required

3. Create a Dockerfile with the following contents:

   Debian

   Ubuntu

   RHEL

   Alpine

4. Build your image with docker build --no-cache -t kong-your-tag .

5. Test that the image built correctly with docker run -it kong-your-tag kong version

6. To run Kong Gateway and process traffic, follow the Docker install instructions, replacing the image name with your custom name
