Manifest Checkers

A collection of applications used to help build and check Kubernetes manifests at Utility Warehouse.

kustomize-build-dirs

kustomize-build-dirs takes a list of filenames, and for each one walks up the directory tree until it finds a directory containing kustomization.yaml then runs kustomize build on that directory, saving the output in the directory given by --out-dir.

This program should only be run from the root of a Git repository.

Usage:

NAME:
   kustomize-build-dirs - Given a list of input files, run `kustomize build` somewhere

USAGE:
   kustomize-build-dirs [global options] command [command options] 

COMMANDS:
   help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --out-dir value     Directory to output build manifests
   --truncate-secrets  Whether or not to truncate secrets. This can make life easier when you don't have strongbox credentials for some secrets (default: false)
   --help, -h          show help

Example:

git diff --diff-filter d --name-only main | xargs kustomize-build-dirs --out-dir manifests/ --

For each kustomize directory the directory tree from the repo root to that directory will be constructed in the output dir and the built manifests stored in 'manifests.yaml' there. For example, if there is a kustomize directory at 'project-manifests', then running

kustomize-build-dirs --out-dir build project-manifests

Will result in the built manifests being placed at 'build/project-manifests/manifests.yaml'

Passing the --truncate-secrets flag will cause the application to empty any files that look to be strongbox encrypted before running kustomize build, so the contents of any secrets will not be present in the output. This may be useful to avoid requiring extra broadly scoped credentials in e.g. CI environments which wouldn't otherwise need them.

validate-opslevel-annotations

validate-opslevel-annotations checks the OpsLevel annotations for a list of manifests are valid against what our opslevel setup expects..

It will process an entire manifest file and report on all errors across all objects therein, though it will bail upon the first manifest it can't read or can't interpret.

Usage:

validate-opslevel-annotations [ manifest-file] ...
