Apache NiFi was made for dataflow. It supports highly configurable directed graphs of data routing, transformation, and system mediation logic. Some of its key features include:
- Web-based user interface
- Seamless experience for design, control, and monitoring
Issuing `bin/nifi.sh start` executes the `nifi.sh` script that starts NiFi in the background and then exits. If you want `nifi.sh` to wait for NiFi to finish scheduling all components before exiting, use the `--wait-for-init` flag with an optional timeout specified in seconds.
MiNiFi is a child project effort of Apache NiFi. It is a complementary data collection approach that supplements the core tenets of [NiFi](https://nifi.apache.org/) in dataflow management, focusing on the collection of data at the source of its creation.
Specific goals for MiNiFi are comprised of:
- small and lightweight footprint
- central management of agents
- generation of data provenance
- integration with NiFi for follow-on dataflow management and full chain of custody of information
Perspectives of the role of MiNiFi should be from the perspective of the agent acting immediately at, or directly adjacent to, source sensors, systems, or servers.
To run:
- Change directory to 'minifi-assembly'. In the target directory, there should be a build of minifi.
$ cd minifi-assembly
$ ls -lhd target/minifi*
drwxr-xr-x 3 user staff 102B Jul 6 13:07 minifi-1.14.0-SNAPSHOT-bin
-rw-r--r-- 1 user staff 39M Jul 6 13:07 minifi-1.14.0-SNAPSHOT-bin.tar.gz
-rw-r--r-- 1 user staff 39M Jul 6 13:07 minifi-1.14.0-SNAPSHOT-bin.zip
- For testing ongoing development you could use the already unpacked build present in the directory
named "minifi-*version*-bin", where *version* is the current project version. To deploy in another
location make use of either the tarball or zipfile and unpack them wherever you like. The
distribution will be within a common parent directory named for the version.
$ mkdir ~/example-minifi-deploy
$ tar xzf target/minifi-*-bin.tar.gz -C ~/example-minifi-deploy
$ ls -lh ~/example-minifi-deploy/
total 0
drwxr-xr-x 10 user staff 340B Jul 6 01:06 minifi-1.14.0-SNAPSHOT
To run MiNiFi:
- Change directory to the location where you installed MiNiFi and run it.
- For help building your first data flow and sending data to a NiFi instance see the System Admin Guide located in the docs folder or making use of the minifi-toolkit, which aids in adapting NiFi templates to MiNiFi YAML configuration file format.
- If you are testing ongoing development, you will likely want to stop your instance.
$ cd ~/example-minifi-deploy/minifi-*
$ ./bin/minifi.sh stop
### Docker Build
To build:
- Run a full NiFi build (see above for instructions). Then from the minifi/ subdirectory, execute `mvn -P docker clean install`. This will run the full build, create a docker image based on it, and run docker-compose integration tests. After it completes successfully, you should have an apacheminifi:${minifi.version} image that can be started with the following command (replacing ${minifi.version} with the current maven version of your branch):
```
docker run -d -v YOUR_CONFIG.YML:/opt/minifi/minifi-${minifi.version}/conf/config.yml apacheminifi:${minifi.version}
