Bitnami kube-manifests

A collection of misc kubernetes configs for various jobs, as used in Bitnami's production clusters. This is probably not useful directly for anyone else, but we hope it serves as a non-demo example of "real" Kubernetes configuration.

Most of the code comments and instructions below are intended for Bitnami employees making changes to our production clusters.

Uses jsonnet and kubectl command line tools. See Makefile for a docker container with these installed.

Cheat Sheet

# Rebuild generated json (from jsonnet).
# Any modified files should be included in your git commit.
make build

# Run test-suite
make test

# Create resources
./tools/kubecfg.sh squid.jsonnet create
# Update resources
./tools/kubecfg.sh squid.jsonnet update

# Same thing directly for whatever reason
jsonnet -J lib squid.jsonnet | kubectl replace -f -
# .. or using the generated json
kubectl replace -R -f generated/one.k8s.dev.bitnami.net/squid


  • Usual github pull-request workflow: Fork the github repo, clone locally and make your desired change to the jsonnet files using your favourite editor.

  • Run make to regenerate the JSON. Add the generated files to your commit. You (and your reviewer) can use these to confirm that your jsonnet change does what you expect.

  • If you need to iterate interactively, you can push your change to our dev cluster using ./tools/kubecfg.sh one.k8s.dev.bitnami.net/foo.jsonnet update. Try to clean up after yourself.

  • When ready, push to personal github fork and create a pull request in the usual github way.

  • Our jenkins instance will run tests/test_*.sh and report success/failure on the pull-request.

  • After jenkins success and appropriate reviewer approval, merge the pull request into the master branch.

  • Jenkins will now automatically run ./tools/deploy.sh against each cluster.


./tests/test_*.sh will be run against the codebase before merge.

Note that tests/test_generated.sh asserts that generated/ is up to date, effectively requiring every substantive jsonnet change to run tools/rebuild.sh.

Directory Layout

The interesting bit is these directories:

├── common
│   └── config
├── one.k8s.dev.bitnami.net
│   └── config
├── one.k8s.int.bitnami.net
│   └── config
└── one.k8s.web.bitnami.net
    └── config

Most of the configuration is in per-component files in common/. These files are then assembled and "specialised" in per-cluster files below each of the cluster-named directories. There is a similar foo/config/ directory stack used in a similar way for non-Kubernetes config files (mostly prometheus at the moment).

The jsonnet files rely heavily on lib/kube.libsonnet, which contains jsonnet black-magic to help construct objects that conform to the regular Kubernetes (JSON/YAML) API schema.
