k8s: Dynatrace Operator YAMLをyqで一括名前変更

前回 Dynatrace Operator YAML マニフェストファイルを分割しました。以下のようなファイル群がある状態です。

$  ls
Operator140_00  Operator140_04  Operator140_08  Operator140_12  Operator140_16  Operator140_20
Operator140_01  Operator140_05  Operator140_09  Operator140_13  Operator140_17  Operator140_21
Operator140_02  Operator140_06  Operator140_10  Operator140_14  Operator140_18  Operator140_22
Operator140_03  Operator140_07  Operator140_11  Operator140_15  Operator140_19  Operator140_23

このファイル名を意味あるものに変えようと思います。ファイルの内容中に意味のある文字列があるのでそれらをyqコマンドで抜き出してみます。

$ yq .kind Operator140_07
CustomResourceDefinition
$ yq .metadata.name Operator140_07
dynakubes.dynatrace.com
$ yq '.kind += "_"|.kind += .metadata.name|.kind' Operator140_07
CustomResourceDefinition_dynakubes.dynatrace.com

ユニークな文字列として使えそうですね。一括名前変換してlsで一覧してみました。

$ for i in *; do  mv $i $(yq '.kind += "_"|.kind += .metadata.name|.kind' $i).yaml; done
$ ls -l
