The commands on the lines in this Dockerfile are as follows:

説明
003 から 005 Specifies that the base image to use is the official Docker image for .NET Framework on Windows Server 2016 Server Core.
014 から 020 docker build コマンドで渡すビルド引数を定義します。
  • PRODUCT_VERSION。この Dockerfile が付属する Enterprise Developer のバージョンを示します。
  • MFLICFILE。Enterprise Developer に使用するライセンス ファイルの名前を指定します。
  • ACCEPT_CONTAINER_EULA。使用許諾契約書の内容に同意することを示します。デフォルトの設定は「no」です。したがって、使用許諾契約書の内容に同意することを示すには変更する必要があります。
  • SETUP_EXE。 Specifies the name of the Enterprise Developer installation file. The default setting is the name of the file supplied with Enterprise Developer.
  • TOOLS_LOC。Specifies the folder into which Enterprise Developer will be installed.
  • JAVAZIPFILE. Specifies the name of the installation file for OpenJDK from AdoptOpenJDK.
  • TMP_INST_DIR。イメージの作成中に使用する一時ディレクトリを指定します。不要になったら削除されます。
022 から 027 作成するイメージのメタデータ ラベルを指定します。これらのラベルは docker inspect コマンドで照会できます。
030 から 031 この Dockerfile で使用する環境変数を作成します。
  • TOOLS_LOC is copied from the build argument defined previously.
  • RMT_DIR specifies the location of the COBOL licensing management software. This is installed when you install Enterprise Developer.
034 Specifies that the shell to be used for subsequent instructions is ["cmd", "/S", "/C"].

This is the default for Dockerfiles on Windows but needs to be specified explicitly here because the base image for this Dockerfile is a Microsoft .NET Framework "-build" image, and using that image causes PowerShell to be used as the shell.

037 から 038 Copies the Enterprise Developer installation file into the temporary folder and the Enterprise Developer license file into the folder where Enterprise Developer is to be installed.
041 Sets the Docker working directory to be the temporary directory.
042 から 045 Run the Enterprise Developer installation file specifying parameters to install it silently, into the required directory, creating a log file, and indicating that you have accepted the terms laid out in the license agreement.
048 から 049 Runs a series of concatenated Windows commands to search the Enterprise Developer installation log file for text indicating that the installation failed. If any such text is found no further processing takes place.
052 から 055 Run a series of concatenated Windows commands to license Enterprise Developer.
058 から 064 Copy the OpenJDK .zip file and the getAdoptOpenJDK.ps1 PowerShell script, then run a series of concatenated Windows comments to set up the Java environment and delete any files that are no longer required.
067 から 070 イメージで Ant のサポートを有効にします。具体的には、ANT_HOME 環境変数および PATH 環境変数を、それぞれ適切なフォルダーを含むように設定します。
073 から 074 Runs a series of concatenated Windows commands to delete the Enterprise Developer installation file and the temporary directory that was used to contain it.
077 Sets the Docker working directory to be the directory into which Enterprise Developer was installed.
