Using bld.sh to Create the Application Image

Use bld.sh to create an application image from the base image, including the files in AppContainerDirectory.

Usage

bld.sh IacceptEULA app

Parameters

IacceptEULA: Indicates the acceptance of the End User License Agreement (EULA). This parameter is required.
app: Build an image based on the extend image and includes the AppContainerDirectory.

podman Specifications

bld.sh runs the podman build command as follows:

podman build \
   --tag $APPIMAGE \
   --format docker \
   --build-arg BASEIMAGE=$BASEIMAGE \
   --build-arg EXTEND_VERSION=$EXTEND_VERSION \
   --build-arg APPCONTAINERDIRECTORY="$PWD\AppContainerDirectory" \
   --file ${DOCKERFILE}_app \
   .

Where:

--tag: Sets a name for the built application image
--format: Tells bld.sh to use Docker format, which in this case is Docker version 2, schema format 2 for the manifest.
--build-arg: Sets variables that get used in the Dockerfile specified by the --file option.
--file: Specifies the name of the Docker file that contains the application image creation commands.
.: Tells podman to look for files and subdirectories in the current directory.

Dockerfile_linux_x64_app

The Dockerfile_linux_x64_app file contains the following commands to create the application image:

# Name of the repository tag used to create the application image 
# Can be overridden with the --build-arg option in bld.sh 
ARG BASEIMAGE=${BASEIMAGE} 
 
# Use the base extend image to create the application image 
FROM ${BASEIMAGE} 
 
# Default Dockerfile values 
# Values can be overridden with the --build-arg options in bld.sh 
# These need to come after the FROM command or else they will not have a value 
ARG EXTEND_VERSION=${EXTEND_VERSION} 
ARG APPCONTAINERDIRECTORY=${APPCONTAINERDIRECTORY} 
 
# Embed the label information into the application image for identification. 
# This can be viewed with podman image inspect <image-id> 
LABEL vendor="Micro Focus" \ 
      com.microfocus.name="extend-app" \ 
      com.microfocus.version="$EXTEND_VERSION" \ 
      com.microfocus.eula.url="https://supportline.microfocus.com/licensing/lvcontract.aspx" \ 
      com.microfocus.is-base-image="false" 
 
# Copy the local application directory to the root directory in the image 
COPY ["AppContainerDirectory", "/AppContainerDirectory/"] 
 
# Set permissions needed for running the applications 
RUN chmod 644 /AppContainerDirectory/AcuAccess* 
RUN chmod 644 /AppContainerDirectory/*.cfg 
RUN chmod 644 /AppContainerDirectory/*.ini 
RUN chmod 644 /AppContainerDirectory/*.conf 
RUN chmod 644 /AppContainerDirectory/*.acu 
RUN chmod 744 /AppContainerDirectory/*.sh

If bld.sh runs without errors, you can use the following command to list all the images:

podman images

The application image has the following repository and tag name, including the suffix -app on the repository name to differentiate it from the base image:
