Rabble

Building

Requirements

The only requirement to build Rabble is to have docker installed.

Steps

Run run_build.sh and the output binaries will be written to a build_out directory.

Configuration

There are a few parameters you can use to configure your Rabble instance. To change these options set the corresponding environment variable when running run_build.sh. Unset values have sensible defaults.

• RABBLE_SEARCH_TYPE:
  • bleve (default)
  • simple-search
• RABBLE_FOLLOW_RECOMMENDER_METHOD:
  • none (default)
  • surprise
  • cn
  • graphdist
• RABBLE_POSTS_RECOMMENDER_METHOD:
  • none (default)
  • random

Running Rabble

After doing a build you can run Rabble by executing the start.sh script. Docker and docker-compose are both requried.

NOTE: If you have made changes to a microservice it will only be rebuilt if its context directory changes. To manually rebuild run docker-compose build --no-cache <service_name>

Adding a new microservice to the build

To add a new microservice follow these steps:

• Add new build dependencies (compilers, libraries, ...) to build_container/Dockerfile
• Add the build commands to build_container/build.sh
• Create a Dockerfile in the microservice's directory that runs the microservice
• Add the new service to docker-compose.yml
• Test!

Running Rabble in Production

To run Rabble on a production server, first go and edit your configs.

Config Path	Description
containers/gen_first_config.sh	Build Environment Variables
chump/rabble_config.js	Frontend constants

The most important environment variables to change are:

• RABBLE_EXTERNAL_ADDRESS - gen_first_config.sh - this should be the domain of the your instance
