CORBAサービスベアイメージ作成時に使用するDockerfileの定義内容を以下の図に記載します。
なお、以下の図は、ベースイメージにregistry.access.redhat.com/rhel7.3を使用する例です。赤字の部分は環境に合わせて修正してください。
CORBAサービスでCOBOLアプリケーションを使用する場合は、NetCOBOLインストール済みのDockerイメージ（COBOL開発資産未配備のベアイメージ）をDockerfileのbase imangeに指定してください。NetCOBOL環境の構築方法は、NetCOBOL Enterprise Editionのマニュアルを参照してください。
