Automated KrakenD deployments with CI/CD

Document updated on Dec 7, 2021

KrakenD operates with its single binary and your associated configuration. Therefore, your build process or CI/CD pipeline only needs to ensure that the configuration file is correct. These are a few recommendations to a safes KrakenD deployment:

1. Make sure the configuration file is valid. When using Flexible Configuration, generate the final krakend.json using FC_OUT as the final artifact
2. Optional - Generate an immutable docker image
3. Optional - Run integration tests
4. Deploy the new configuration

There are several ways to automate KrakenD deployments, but you must always test your configuration before applying it in production. You’ll find a few notes that might help you automate this process in this document.

For the first step, the check command is a must in any CI/CD pipeline or pre-deploy process to ensure you don’t put a broken setup in production that results in downtime. The check command lets you find broken configurations before going live. Add a line like the following in your release process:

$krakend check -t -d -c /path/to/krakend.json

The command above will stop the pipeline (exit 1) if it fails or continue if the configuration is correct. Make sure to always place it in your build/deploy process.
