Kustomize Wrapper 
A Python wrapper for the Kubernetes Kustomize tool and related tooling.
- More readable, more concise one-liners
- Easy linting (with integrated
kubeval) - Integrates into your Python tooling (e.g. use it with
tox) - Automatic download of external Go binaries
- Cross-platform (installs matching Go binaries on Linux, macOS, Windows)
Installation
python3 -m pip install kustomize-wrapper
Why should I use this tool
Forget about several kustomize calls, piping your calls into kubeval
or kubectl apply commands. Using Kustomize is now even more pleasant!
Instead of:
lint:
script:
- kustomize build deployment/overlays/development | kubeval --strict
- kustomize build deployment/overlays/integration | kubeval --strict
- kustomize build deployment/overlays/production | kubeval --strict
You can now write:
lint:
script:
- kustomize lint deployment/overlays/*
Instead of:
production:
script:
- cd deployment/base
- kustomize edit set image IMAGE="foobar/application:${CI_COMMIT_SHA}"
- cd ../..
- kustomize build deployment/overlays/production | kubectl apply -f -
You can now write:
production:
script:
- kustomize apply deployment/overlays/production --edit deployment/base \
set image IMAGE="foobar/application:${CI_COMMIT_SHA}"
Usage
kustomize --help
Philosophy:
- Build automatically
- Kustomize commands become CLI options
- Kubeval options become CLI options of
lintcommand
Python tox
Add kustomize-wrapper to your tox.ini, then Tox takes care of downloading:
[testenv:kubernetes]
description = Validate Kubernetes manifests
deps = kustomize-wrapper
commands =
kustomize lint {posargs:--ignore-missing-schemas --fail-fast \
deployment/application/overlays/development \
deployment/application/overlays/integration \
deployment/application/overlays/production \
}
Allows you to override arguments: (Use -- in case you add command line options)
tox -e kubernetes -- --fail-fast deployment/application/base
