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](https://github.com/paralus/paralus/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22)” 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](https://github.com/paralus/paralus/issues/new) 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](https://github.com/postgres/postgres): Primary database - [Ory Kratos](https://www.ory.sh/kratos): API for user management - [Elasticsearch](https://www.elastic.co/elasticsearch/): Storage for audit logs > You can use the > [bitnami/charts](https://github.com/bitnami/charts/tree/master/bitnami/postgresql/#installing-the-chart) > for postgres and > [elastic/helm-charts](https://github.com/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._ ```bash docker-compose --env-file ./env.example up -d ``` Start core: ```bash go run github.com/paralus/paralus ``` ### Manual #### Start databases ##### Postgres ```bash docker run --network host \ --env POSTGRES_HOST_AUTH_METHOD=trust \ -v pgdata:/var/lib/postgresql/data \ -it postgres ``` ##### Elasticsearch ```bash 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 ```sql create database admindb; CREATE ROLE admindbuser WITH LOGIN PASSWORD ''; GRANT ALL PRIVILEGES ON DATABASE admindb to admindbuser; ``` #### Ory Kratos Install Ory Kratos using the [installation guide](https://www.ory.sh/docs/kratos/install) from Kratos documentation. Perform the Kratos migrations: ```bash export DSN='postgres://:@:/admindb?sslmode=disable' kratos -c migrate sql -e --yes ``` Start the Ory Kratos server using kratos config provided in [_kratos](./_kratos) directory. #### Run application migrations We use [`golang-migrate`](https://github.com/golang-migrate/migrate) to perform migrations. ##### Install [`golang-migrate`](https://github.com/golang-migrate/migrate) ```shell 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](https://github.com/golang-migrate/migrate/tree/master/cmd/migrate) for full details. ##### Run migrations _It is required to perform Kratos migrations before this step._ ```shell export POSTGRESQL_URL='postgres://:@:/admindb?sslmode=disable' migrate -path ./persistence/migrations/admindb -database "$POSTGRESQL_URL" up ``` See [cli-usage](https://github.com/golang-migrate/migrate#cli-usage) for more info. #### Start Paralus Start Paralus: ```bash go run github.com/paralus/paralus ``` #### Updating Proto Files? - Make sure you have [`buf`](https://github.com/bufbuild/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 ## DCO Sign off All authors to the project retain copyright to their work. However, to ensure that they are only submitting work that they have rights to, we are requiring everyone to acknowledge this by signing their work. Any copyright notices in this repo should specify the authors as "the paralus contributors". To sign your work, just add a line like this at the end of your commit message: ``` Signed-off-by: Joe Bloggs ``` This can easily be done with the `--signoff` option to `git commit`. You can also mass sign-off a whole PR with `git rebase --signoff master`, replacing `master` with the branch you are creating a pull request against, if not master. By doing this you state that you can certify the following (from https://developercertificate.org/): ``` Developer Certificate of Origin Version 1.1 Copyright (C) 2004, 2006 The Linux Foundation and its contributors. 1 Letterman Drive Suite D4700 San Francisco, CA, 94129 Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
