Build your own Docker images

Kong is distributed as prebuilt 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.

The 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 docker-entrypoint.sh script from docker-kong and make it executable:

    1. chmod +x docker-entrypoint.sh

  2. Download the Kong Gateway package:

  3. Create a Dockerfile, ensuring you replace the filename by the first COPY with the name of the Kong Gateway file you downloaded in step 2:

  1. Build your image:

    1.  docker build --platform linux/amd64 --no-cache -t kong-image .

  2. Test that the image built correctly:

    1.  docker run -it --rm kong-image kong version

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