Apache NiFi Registry Build Status

Registry—a subproject of Apache NiFi—is a complementary application that provides a central location for storage and management of shared resources across one or more instances of NiFi and/or MiNiFi.

Table of Contents

Getting Started

Requirements

  • Java 1.8 (above 1.8.0_45)
  • Maven 3.1.0, or newer
  • Recent git client

  1. Clone the repo

     git clone https://git-wip-us.apache.org/repos/asf/nifi-registry.git
 git checkout master

  2. Build the project

     cd nifi-registry
 mvn clean install

    If you wish to enable style and license checks, specify the contrib-check profile:

     mvn clean install -Pcontrib-check

  3. Start the application

     cd nifi-registry-assembly/target/nifi-registry-<VERSION>-bin/nifi-registry-<VERSION>/
 ./bin/nifi-registry.sh start

    Note that the application web server can take a while to load before it is accessible.

  4. Accessing the application web UI

    With the default settings, the application UI will be available at http://localhost:18080/nifi-registry

  5. Accessing the application REST API

    If you wish to test against the application REST API, you can access the REST API directly. With the default settings, the base URL of the REST API will be at http://localhost:18080/nifi-registry-api. A UI for testing the REST API will be available at http://localhost:18080/nifi-registry-api/swagger/ui.html

  6. Accessing the application logs

    Logs will be available in logs/nifi-registry-app.log

Database Testing

In order to ensure that NiFi Registry works correctly against different relational databases, the existing integration tests can be run against different databases by leveraging the Testcontainers framework.

Spring profiles are used to control the DataSource factory that will be made available to the Spring application context. DataSource factories are provided that use the Testcontainers framework to start a Docker container for a given database and create a corresponding DataSource. If no profile is specified then an H2 DataSource will be used by default and no Docker containers are required.

Assuming Docker is running on the system where the build is running, then the following commands can be run:

Target Database Build Command
All supported mvn verify -Ptest-all-dbs
H2 (default) mvn verify
PostgreSQL 9.x mvn verify -Dspring.profiles.active=postgres
PostgreSQL 10.x mvn verify -Dspring.profiles.active=postgres-10
MySQL 5.6 mvn verify -Pcontrib-check -Dspring.profiles.active=mysql-56
MySQL 5.7 mvn verify -Pcontrib-check -Dspring.profiles.active=mysql-57
MySQL 8 mvn verify -Pcontrib-check -Dspring.profiles.active=mysql-8

When one of the Testcontainer profiles is activated, the test output should show logs that indicate a container has been started, such as the following:

2019-05-15 16:14:45.078  INFO 66091 --- [           main] 🐳 [mysql:5.7]                           : Creating container for image: mysql:5.7

The Flyway connection should also indicate the given database:
