Google Kubernetes Engine(GKE)を使ってNextCloudをデプロイしてみた ※構築手順付き

$ gcloud container clusters create-auto lin-nextcloud-autopilot --region asia-northeast1

$ gcloud container clusters get-credentials lin-nextcloud-autopilot --region asia-northeast1

$ kubectl create secret tls sbcicp1.net --cert sbcicp1.net.pem --key sbcicp1.net.key
