Getting Started with CrazyIvan¶
Docker¶
The easiest way to get started with CrazyIvan is with Docker
If you do not have Docker installed, please visit the link above to get setup before continuing.
The first thing we need to do is setup the Docker Network that will allow us to communicate between our containers:
docker network create dvs
Before we can start CrazyIvan, we need to have a few other programs running first. Luckily, these can all be setup with Docker as well:
docker run -d --name=registry --network=dvs consul
docker run -d --publish=7474:7474 --publish=7687:7687 --env=NEO4J_AUTH=none --volume=$HOME/neo4j/data:/data --network=dvs --name=database neo4j
docker run -i -t -d -p 2181:2181 -p 9092:9092 --env ADVERTISED_PORT=9092 --env ADVERTISED_HOST=queue --name=queue --network=dvs spotify/kafka
This will start up a single instance each of Neo4j, Kafka, and Consul. Consul stores our configuration values, so we’ll need to set those up. You can either view the Consul Documentation for information on starting the container with a Web UI, or you can use the commands below for a quick-and-dirty setup:
docker exec -t registry curl -X PUT -d 'neo4j://graph-db:7687' http://localhost:8500/v1/kv/ivan/DB_ConnectionString
docker exec -t registry curl -X PUT -d 'queue:9092' http://localhost:8500/v1/kv/ivan/KafkaBrokerAddress
docker exec -t registry curl -X PUT -d 'True' http://localhost:8500/v1/kv/ivan/StampTransactionId
docker exec -t registry curl -X PUT -d 'Json' http://localhost:8500/v1/kv/ivan/Data_Format_Type
Then, we can start up CrazyIvan:
docker run --name crazyivan --network=dvs -p 5555:5555 -d aostreetart/crazyivan -consul-addr=registry:8500 -ip=localhost -port=5555 -log-conf=CrazyIvan/log4cpp.properties
This will start an instance of CrazyIvan with the following properties:
- Connected to network ‘dvs’, which lets us refer to the other containers in the network by name when connecting.
- Listening on localhost port 5555
- Connected to Consul Container
We can open up a terminal within the container by:
docker exec -i -t crazyivan /bin/bash
The ‘stop_crazyivan.py’ script is provided as an easy way to stop CrazyIvan running as a service. This can be executed with:
python stop_crazyivan.py hostname port
For a more detailed discussion on the deployment of CrazyIvan, please see the Deployment Section of the documentation.
Using the Latest Release¶
In order to use the latest release, you will still need to start up the applications used by CrazyIvan, namely Neo4j, Kafka, and Consul. This can be done using the docker instructions above, or by installing each to the system manually. Instructions: * Neo4j * Consul
Then, download the latest release from the Releases Page
Currently, pre-built binaries are available for:
- Ubuntu 16.04
- CentOS7
Unzip/untar the release file and enter into the directory. Then, we will use the easy_install.sh script to install CrazyIvan. Running the below will attempt to install the dependencies, and then install the CrazyIvan executable:
sudo ./easy_install.sh -d
If you’d rather not automatically install dependencies, and only install the executable, then you can simply leave off the ‘-d’ flag. Additionally, you may supply a ‘-r’ flag to uninstall CrazyIvan:
sudo ./easy_install -r
Once the script is finished installing CrazyIvan, you can start CrazyIvan with:
sudo systemctl start crazyivan.service
The ‘stop_crazyivan.py’ script is provided as an easy way to stop CrazyIvan running as a service. This can be executed with:
python stop_crazyivan.py hostname port
Note: The CrazyIvan configuration files can be found at /etc/crazyivan, and the log files can be found at /var/log/crazyivan.
Building from Source¶
The recommended system for development of CrazyIvan is either Ubuntu 16.04 or CentOS7. You will need gcc 5.0 or greater installed to successfully compile the program.
git clone https://github.com/AO-StreetArt/CrazyIvan.git
mkdir crazyivan_deps
cp CrazyIvan/scripts/linux/deb/build_deps.sh crazyivan_deps/build_deps.sh
cd crazyivan_deps
./build_deps.sh
You will be asked once for your sudo password.
cd ../CrazyIvan
make
This will result in creation of the crazy_ivan executable, which we can run with the below command:
./crazy_ivan
When not supplied with any command line parameters, CrazyIvan will look for an ivan.properties file and log4cpp.properties file to start from.
You may also build the test modules with:
make tests
In order to run CrazyIvan from a properties file, you will need:
- You will also need to have a Neo4j Server installed locally. Instructions can be found at https://neo4j.com/developer/get-started/
Continue on to the Configuration Section for more details on the configuration options available when starting CrazyIvan.
