Kubernetes:Dynatrace Operator YAMLマニフェストを分解してみる

Posted at

こんばんわ。Dynatrace井上です。

K8S を監視観測する場合、多くの場合Dynatrace Operatorを使います。

マニフェストYAMLファイルへのリンクは例えば以下のドキュメントページに出てきます。

このYAMLファイルは実際は複数YAMLの結合です。

その境界は「---(ハイフン3つ)」で仕切ります

通常は必要ないですが例えばバージョン間の差分を知りたいなどの場合分解して比較してみたくなることもあるかと思います。そこで試したのが以下の分解方法です。

$ mkdir Dynatrace_k8s
$ curl --silent --location \
 https://github.com/Dynatrace/dynatrace-operator/releases/download/v0.14.0/kubernetes.yaml |
 csplit --silent --elide-empty-files --prefix Dynatrace_k8s/Operator140_ - '/^---$/' {*}
$ ls -l Dynatrace_k8s
total 320

これだけだとファイル名が連番になるだけなので、ファイル名を意味あるものに一括変更する方法を探してみます。
