🛠 IBM webMethods container Image Builder

This repository includes a build.sh script for building custom Docker images using predefined templates. The script supports dynamic template selection, image naming, and a debug mode.

---

Prerequisites

• Download th IBM webMethods Installer from IBM and copy the file as installer.binto the root folder
• get an entitlement key and user from IBM
• Set the environments variables (see Environment Variables)

🚀 Usage

./build.sh [-t template] [-i image] [-d]

Options

• -t template
  The template directory inside ./templates/ to use for building the image.
  Example: -t mws (which uses ./templates/mws/)

• -i image
  The name (and optionally tag) of the image to build.
  Example: -i myimage:latest

• -d
  Debug mode. Only runs the docker build command without appending the installation instructions from the template.

---

🔧 Requirements

Dependencies

• Docker or Podman installed
• installer.bin file placed in the project root directory
• A products file inside the template directory listing the products to install
• A valid Dockerfile in the repository (used as the base Dockerfile)
• A templates/<template>/Dockerfile and templates/<template>/install file to extend the base image

Environment Variables

You must set the following environment variables before running build.sh:

• ENTITLEMENT_USER – Your IBM entitlement username
• ENTITLEMENT_KEY – Your IBM entitlement key
• INSTALLER_VERSION – (Optional) Version of the installer
• RELEASE – (Optional) Release name or version
• ADMIN_PASSWORD – (Optional) Password for the admin user
• BASE_IMAGE – (Optional) Base image to use in the Docker build

---

📂 Template Structure

A typical template directory should look like this:

templates/
  <template>/
    Dockerfile          # Docker instructions specific to this template
    install             # Installation instructions appended to Dockerfile.tmp
    products            # List of products to be installed

---

🧪 Debug Mode

Use -d to enable debug mode:

./build.sh -t mws -i testimage:debug -d

This will:

• Skip adding the template's Dockerfile and install content
• Run only the raw docker build command

---

🧹 Cleanup

Temporary files Dockerfile.tmp and installer.script.tmp may be created during build. Remove them if needed:

rm -f Dockerfile.tmp installer.script.tmp

---

🔍 Example Command

ENTITLEMENT_USER=myuser ENTITLEMENT_KEY=mykey RELEASE=1015 BASE_IMAGE=docker.io/redhat/ubi8:latest ADMIN_PASSWORD=manage ./build.sh -t mws -i mws-custom:10.15

⚠️ Notes

• Make sure to download installer.bin from IBM FixCentral (search for webMethods Installer).
