ヘッドレスCMSとしても使えるGhostをDigitalOceanのManaged k8s cluster(DOKS)にhelmでインストールしてみる。
ヘッドレスCMSのstrapiも試してみたかったが、2022/3月時点で公式やbitnamiのHelm Chartがないので断念。
Setup MySQL Database for Ghost
k8s clusterにインストール済みのMySQL(ns:mysql/svc:mysql)にGhost用Databaseを作成。
create database ghost;
create user hogehoge identified by 'hogehoge';
GRANT ALL PRIVILEGES ON ghost.* TO hogehoge@'%';
FLUSH PRIVILEGES;Installing Ghost by Helm
下記をインストール。
helm search repo ghost
