Prerequisites

To get necessary build and generation dependencies:

make init

Build

make build

Run

make run

Create a service

# Create a template project
kratos new server

cd server
# Add a proto template
kratos proto add api/server/server.proto
# Generate the proto code
kratos proto client api/server/server.proto
# Generate the source code of service by proto file
kratos proto server api/server/server.proto -t internal/service

go generate ./...
go build -o ./bin/ ./...
./bin/server -conf ./configs

Generate other auxiliary files by Makefile

# Generate API files (include: pb.go, http, grpc, validate, swagger) by proto file
make api
# Generate all files
make all

Automated Initialization (wire)

# install wire
go get github.com/google/wire/cmd/wire

# generate wire
cd cmd/server
wire

Spicedb using docker/podman

Run the spicedb

make spicedb

Run the insights-rebac with docker compose

make rebac

teardown spicedb and postgresql db

make spicedb/teardown

Deploy Rebac and Spicedb using kind/kubernetes

make kind/rebac

Docker

# build
docker build -t <your-docker-image-name> .

# run
docker run --rm -p 8000:8000 -p 9000:9000 -v </path/to/your/configs>:/data/conf <your-docker-image-name>

Deploy to a openshift cluster that has Clowder

Prerequisite

bonfire

NOTE: The minimum required version of bonfire is specified in the MIN_BONFIRE_VERSION variable in the deploy.sh script Bonfire could be upgraded by command:

pip install --upgrade crc-bonfire

Latest version of bonfire could be found here.

oc

You should have logged into a valid openshift cluster using the oc login command

oc login --token=<token> --server=<openshift server>

Deploying the components

Option 1: Using the config from app-interface (RedHat Internal only)

• Create a config map inside a local directory. You can refer to here
  • NOTE: Please replace the "data" section, as per your needs (the schema portion)
• Run the following command:
  • bonfire deploy relations --import-configmaps --configmaps-dir <path-to-configmaps-dir>

Option 2: Using the deploy.sh script in this repository

Note: the deploy script assumes you have a valid oc login and the necessary tools are in place.

The deploy script under the deploy folder, will deploy all the needed components.

./deploy.sh

• Creates a postgres pod and service (Note: No PVC)
• Creates a spiceDB secret - that contains: a preshared key and Postgres connection URI
• Creates a Configmap object - that serves as a bootstrap schema for spiceDB (by default it uses the schema.yaml file under deploy)
• Creates the spiceDB service
• Creates the relations service

You should be able to use the public route (relations-*) created by the clowder in your namespace, to use the service.

Deploying the components with rbac

This is demonstrating calling relationship api from rbac service in ephemeral environment.

./deploy.sh rbac <path_to_local_copy_of_insights_rbac>

path_to_local_copy_of_insights_rbac is this repository

Example:

./deploy.sh rbac /Projects/insights-rbac

• Updates config bonfire file and add rbac component
• Deploys rbac together with relationships application
  • Hardcoded image is used with grpc client for calling relationships
