We 💚 Opensource!

Yes, because we feel that it’s the best way to build and improve a product. It allows people like you from across the globe to contribute and improve a product over time. And we’re super happy to see that you’d like to contribute to Paralus.

We are always on the lookout for anything that can improve the product. Be it feature requests, issues/bugs, code or content, we’d love to see what you’ve got to make this better. If you’ve got anything exciting and would love to contribute, this is the right place to begin your journey as a contributor to Paralus and the larger open source community.

How to get started?

The easiest way to start is to look at existing issues and see if there’s something there that you’d like to work on. You can filter issues with the label “Good first issue” which are relatively self sufficient issues and great for first time contributors.

Once you decide on an issue, please comment on it so that all of us know that you’re on it.

If you’re looking to add a new feature, raise a new issue and start a discussion with the community. Engage with the maintainers of the project and work your way through.

You'll need to perform the following tasks in order to submit your changes:

• Fork the Paralus repository.
• Create a branch for your changes.
• Add commits to that branch.
• Open a PR to share your contribution.

Below are all the details you need to know about the Paralus repo and get started with the development.

Paralus

This repository contains all the core system components that are the backbone for Paralus.

Prerequisites

• Postgres: Primary database
• Ory Kratos: API for user management
• Elasticsearch: Storage for audit logs

You can use the bitnami/charts for postgres and elastic/helm-charts for elasticsearch.

Development setup

Using docker-compose

Run following Docker Compose command to setup all requirements like Postgres db, Kratos etc. for core.

This will start up postgres and elasticsearch as well as kratos and run the kratos migrations. It will also run all the necessary migrations. It also starts up a mail slurper for you to use Kratos.

docker-compose --env-file ./env.example up -d

Start core:

go run github.com/paralus/paralus

Manual

Start databases

Postgres

docker run --network host \
    --env POSTGRES_HOST_AUTH_METHOD=trust \
    -v pgdata:/var/lib/postgresql/data \
    -it postgres

Elasticsearch

docker run --network host \
    -v elastic-data:/usr/share/elasticsearch/data \
    -e "discovery.type=single-node" \
    -e "xpack.security.enabled=false" \
    -it docker.elastic.co/elasticsearch/elasticsearch:8.0.0

Create the initial db and user

create database admindb;
CREATE ROLE admindbuser WITH LOGIN PASSWORD '<your_password>';
GRANT ALL PRIVILEGES ON DATABASE admindb to admindbuser;

Ory Kratos

Install Ory Kratos using the installation guide from Kratos documentation.

Perform the Kratos migrations:

export DSN='postgres://<user>:<pass>@<host>:<port>/admindb?sslmode=disable'
kratos -c <kratos-config> migrate sql -e --yes

Start the Ory Kratos server using kratos config provided in _kratos directory.

Run application migrations

We use golang-migrate to perform migrations.

Install golang-migrate

go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@latest

-tags 'postgres' is important as otherwise it compiles without postgres support

You can refer to the guide for full details.

Run migrations

It is required to perform Kratos migrations before this step.

export POSTGRESQL_URL='postgres://<user>:<pass>@<host>:<port>/admindb?sslmode=disable'
migrate -path ./persistence/migrations/admindb -database "$POSTGRESQL_URL" up

See cli-usage for more info.

Start Paralus

Start Paralus:

go run github.com/paralus/paralus

• Make sure you have buf installed
• Install dependencies:

go install github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-grpc-gateway@latest
go install github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-openapiv2@latest
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

• Run make build-proto to regenerate proto artifacts
