OracleサーバーのDockerイメージ

Share
   

docker-images/OracleDatabase/SingleInstance at main · oracle/docker-imagesはクライアント側みたいにビルド済みイメージが用意されていないのかな、と思ったらOracle Container Registryにそれらしいものを見つけた。

Home > Database > express

$ docker pull container-registry.oracle.com/database/express:latest

サイズやばい

$ docker images | grep ora

$ docker run -d container-registry.oracle.com/database/express

$ docker ps

Statusがhalthyになるまで1分くらいかかった。
