Helm v3 では、リリース状態がデフォルトだと Secret に保存されます。
その中身を見てみましょう。
Secret をデコードするワンライナー
kubectl get secret sh.helm.release.v1.<RELEASE>.<REVISION> \
-n <NAMESPACE> -o json \
| jq -r '.data.release' \
| base64 -d \
| base64 -d \
| gunzip \
| jq
例
helm upgrade --install flux2 flux2/flux2 \
--version 2.17.0 \
--namespace flux-system \
--create-namespace \
--set policies.create=false
kubectl get secret sh.helm.release.v1.flux2.v1 -n flux-system -o json | jq '.data.release' --raw-output | base64 -d | base64 -d | gunzip | jq
