Apache ManifoldCF SDK 1.0.1

This is the SDK project of Apache ManifoldCF dedicated to developers that need to extend the platform with new components, connectors or integrations using Maven and Docker. On the other hand this SDK can be extremely useful also for all the developers who want to contribute to the ManifoldCF project. This project has started with an initial contribution by @OpenPj and @binduwavell.

The SDK will take care of the following tasks:

• Creating custom containers using the official ManifoldCF Docker Images
• Creating the Docker Volumes for the MCF Maven Repo and the MCF installation
• Preparing the Docker Image for executing the build installing Ant and Maven
• Running the container for executing the building process with Ant and then with Maven
• Copying the entire Maven Repo in the Maven target folder in the host machine (locally)

ManifoldCF SDK is using the ManifoldCF Docker repository: https://hub.docker.com/r/apache/manifoldcf

What's new in v1.0.0

• The Maven profile docker-hub now is including a default Console appender for logging to show standard output in Docker Desktop
• Now the default ManifoldCF dependencies version is 2.27 GA (publicly available)
• Added run-compose.sh script in order to manage the deployment with a Docker Compose template
• Added a quick build-and-redeploy functionality in order to recreate only the ManifoldCF container: ./run-compose.sh reload_mcf

What's new in v0.0.5

• The Maven profile docker-hub now is enabled by default
• MCF SDK now by default is building the image from the official Docker images
• Added a debug port (5005) for accelerate connectors development with remote debugging
• Default Maven dependencies version now is 2.27 (publicly available)

If you need to build your custom Docker image using dependencies built from the MCF source code and stored in the target folder (using the init script mentioned below), please use the local Maven profile.

Using the run-compose.sh script for using official available artifacts A dedicated script is now provided in order to manage the Docker Compose template included with this SDK: mcf-docker-overlay/src/main/docker/docker-compose/docker-compose.yml Below some examples of commands using the run-compose.sh script:

• ./run-compose.sh build_start -> build the ManifoldCF 2.26 container deploying a separated container for PostgreSQL with dedicated volume
• ./run-compose.sh start -> start ManifoldCF platform including the crawler and the PostgreSQL database
• ./run-compose.sh reload_mcf -> rebuild ManifoldCF container keeping PostgreSQL up and running
• ./run-compose.sh purge -> removes the MCF database Docker Volumes

Using the SDK with local Maven dependencies built from source code Examples of commands using the run bash script for a typical usage:

• ./run.sh init 2.26 ga -> start the init process for ManifoldCF 2.27 GA
• ./run.sh init custom-version local /<USER_HOME>/Documents/workspaces/manifoldcf/custom-project -> start the init process for a custom ManifoldCF project
• ./run.sh build_start -> build extensions and run everything with Docker locally using an official ManifoldCF distribution
• ./run.sh build_start_local -> build extensions and run everything with Docker locally using a custom local ManifoldCF source code repository
• ./run.sh start -> start all the containers (MCF dist and PostgreSQL)
• ./run.sh stop -> stop all the containers (MCF dist and PostgreSQL)
• ./run.sh start_local -> start all the containers (custom MCF project and PostgreSQL)
• ./run.sh stop_local -> stop all the containers (custom MCF project and PostgreSQL)

Examples of commands for developing and testing MCF itself:

• ./run.sh init 2.22.1 rc -> start the init process for ManifoldCF 2.22.1 RC
• ./run.sh test -> execute unit and integration tests in the MCF source bundle
• ./run.sh clean -> execute ant clean; mvn clean in the MCF source bundle
• ./run.sh purge -> removes all the Docker Volumes and the MCF init container

Initializing the local Maven repository using Docker (optional)

In order to compile extensions with Maven, the SDK provides an initialization script that will download the source code of ManifoldCF and then build it in the container. At the end of the build process the Maven repository included in the container will be copied in the local folder target/mcf-maven-repo. The local Maven repo will be used as the main reference for compiling the extension code.

The initialization command consists of the following arguments:

• MCF version
• MCF distribution: ga for GA release and rc for a Release Candidate

Example for initializing ManifoldCF 2.27 GA release:

• ./run.sh init 2.26 ga

Example for initializing ManifoldCF 2.27.1 RC release:

• ./run.sh init 2.27.1 rc

The initialization process will be executed with the following command:

• /run.sh init 2.21 ga

Building extensions, overlaying and run Docker

A Dockerfile and a Docker Compose file is provided in order to build the ManifoldCF container and for running the instance with its own database, a PostgreSQL container.

The following command will take care of building extensions, run tests and building and running the ManifoldCF container

• ./run.sh build_start

To stop all the containers:

• ./run.sh stop

Executing tests in the container

For running MCF tests related to the source code bundle:

• ./run.sh test -> execute unit and integration tests for the related MCF version initialized in the Docker Volumes

Docker images, containers and volumes

The Docker images, containers and volumes managed by ManifoldCF SDK are the following:

run.sh (.bat)

The Docker image created with for creating the ManifoldCF installation and Maven repo is mcf-sdk-init. The Docker container built by the SDK in order to create the installation folder and the Maven repo is mcf-sdk-init-container.

Containers & Images

• mcf-sdk-init -> image created with for creating the ManifoldCF installation
• mcf-sdk-init-container -> container built by the SDK in order to create the installation folder and the Maven repo

Volumes

• mcf-maven-repo -> this volume contains the Maven repo created by the initialization process
• mcf-app-volume -> this volume contains the installation storage of ManifoldCF
