私は、永続的ボリュームがなぜ主張されていないのかわかりません、またはこれをさらに診断するために私が取るべきステップはありますか?PersistentVolumeClaimが原因で失敗した永続的なボリュームを要求していないKubernetes: "task-pv-claim"が予期しないものです。
クレームサイズがボリュームサイズと一致する必要がありますか?ボリュームのサイズはGCPのボリュームサイズと一致する必要がありますか?ここ
これはテストし、把握するのは困難である...
私の目標は、ちょうど限りそれはローリング展開をサポートするようにも単一レプリカでWordpressのインスタンスを作成できるようにすることです.... kubectl get pods
