kubernetes APIリソース一覧とショートネームについて
LinuCエヴァンジェリストの鯨井貴博@opensourcetechです。
はじめに
kubernetesでkubectlのコマンド入力を省略形(ショートネーム)で行っている方をみかけたので、
ちょっと調べてみました。
例えば、以下のような使い方です。
kubeuser@kubemaster1:~$ kubectl get po
NAME READY STATUS RESTARTS AGE
nginx-6c67f5ff6f-5vbvf 1/1 Running 0 6d7h
nginx-6c67f5ff6f-lfl8l 1/1 Running 0 6d7h
nginx2-589cdbd4b8-6c848 1/1 Running 0 2d20h
nginx2-589cdbd4b8-sgq8b 1/1 Running 0 2d21h
kubeuser@kubemaster1:~$ kubectl get pods
NAME READY STATUS RESTARTS AGE
nginx-6c67f5ff6f-5vbvf 1/1 Running 0 6d7h
nginx-6c67f5ff6f-lfl8l 1/1 Running 0 6d7h
nginx2-589cdbd4b8-6c848 1/1 Running 0 2d20h
nginx2-589cdbd4b8-sgq8b 1/1 Running 0 2d21h
ショートネーム
"pods"を略して"po"、
"endpoints"を略して"ep"。
これは、ショートネームという表記方法です。
APIリソースとショートネームの一覧

kubernetesの公式ドキュメントにも、情報はあります。

おわりに
たいしたことではないのですが、
こういう小ネタを知っているか知らないかで操作スピードも速くなるし、
ちょっとkubernetesに詳しい人感を出せていいですねw
