ksort

This is a tool which does in-place sort of Kubernetes manifests by Kind.

Description

When installing manifests, they should be sorted in a proper order by Kind. For example, Namespace object must be in the first place when installing them.

ksort sorts manfest files in a proper order by Kind.

Usage

Sort manifest files in the deploy directory in the proper order, and output the result to the stdout.

$ ls ./manifests
deployment.yaml  ingress.yaml  namespace.yaml  service.yaml
$ ksort -f ./manifests

To pass the result into the stdin of kubectl apply command is also convenient.

$ ksort -f ./manifests | kubectl apply -f -

Sort manifests contained the manifest file that is specified.

$ ksort -f ./app.yaml

Sort manifests passed into stdin.

$ cat app.yaml | ksort -f-
