A kpt function container image to run kustomize builds.
It supports a declarative, idempotent build and deployment workflow with kpt and kustomize.
The ./examples/hello-world example within this repository specifies a
Kustomization and a
function ConfigMap using the image mgoltzsche/kustomizr.
Render the kustomization into the output file ./examples/hello-world/deploy/generated.yaml that the function specifies
(could be run each commit):
kpt fn run ./examples/hello-world
Note: If the kustomization accesses non-yaml files within its repository you may need to --mount its directory and specify an absolute path as the function's path parameter since non-yaml resources are not provided to the function via stdin.
Also a CI pipeline should ensure that the generate is always consistent with the source.
If needed kpt setters can be used to change kustomization values to e.g. deploy to a preview namespace:
kpt cfg set ./examples/hello-world namespace mypreviewns
kpt fn run ./examples/hello-world
Enable live deployments for the output directory (let kpt generate the inventory-template.yaml once with component UUID and namespace):
kpt live init ./examples/hello-world/deploy
Apply the rendered output that was written to the deploy sub directory previously (could be run in a CD pipeline):
kpt live apply ./examples/hello-world/deploy
Build the docker image:
make
Run a basic e2e test:
make test
