WorkflowGen for Docker

This repository contains the Dockerfiles used for the WorkflowGen image. You can find the image and a quick documentation on Docker Hub. This repository is designed for documentation purposes. It provides information on how WorkflowGen is set up inside specific images and how it is configured at runtime.

You can get started on the setup by visiting the Dockerfile for a specific version of WorkflowGen and get started on the configuration at runtime by visiting the docker-entrypoint.ps1 script for a specific version of WorkflowGen.

Content of this repository

This repository contains scripts for the pipeline build of this image as well as all the needed resources to build the desired WorkflowGen image at a specific version available in this repository.

Pipeline scripts

• azure-pipelines.yml

  Build definition file for the pipeline.

• update.ps1

  Update script for new versions. It takes template files specified when calling the script to produce a new version or update an existing one in this repository.

• scripts folder

  Contains multiple scripts for the pipeline build.

WorkflowGen version folders

Those folders contains all of the files necessary to build the Docker image of WorkflowGen for a specific version. For example, the 7.15 folder has the following structure:

7.15
    windows
        windowsservercore-ltsc2016
            Dockerfile
            onbuild
                Dockerfile
        windowsservercore-ltsc2019
            Dockerfile
            onbuild
                Dockerfile

The windows folder indicates the platform of the files underneath. The windowsservercore-<version> folders represent the base image currently supported on the platform. The onbuild folder represents a variant of the image. The main image files are located in the folder that represents the base image.

Over time, there will be more versions of WorkflowGen, more base images and more platforms available.

Build a specific version

Prerequisites

• You need Docker installed on your machine in order to build an image.

  For Windows 10

  Follow the instructions in the Docker for Windows documentation page.

  For Windows Server

  Follow the instructions in the Docker Enterprise Edition documentation page.

  To verify that Docker is installed correctly, run the following command:

  docker version

Building

To build a specific version of WorkflowGen, open PowerShell and go to the desired version, platform, and base image folder. For example, if you are on Windows Server 2019 and want to build the latest 7.15 version of WorkflowGen (7.15.5), go to the 7.15\windows\windowsservercore-ltsc2019 folder and execute the following command:

docker build -t advantys/workflowgen:7.15.5-win-ltsc2019 .

To build the ONBUILD variant of the image, go to the 7.15\windows\windowsservercore-ltsc2019\onbuild and execute the following command:

docker build -t advantys/workflowgen:7.15.5-win-ltsc2019-onbuild .

You should now have two Docker images of WorkflowGen in your list of images. To get the images that are on your machine, execute docker image ls.
