A link aggregator / reddit clone for the fediverse.

[Lemmy Dev instance](https://dev.lemmy.ml) *for testing purposes only*

This is a **very early beta version**, and a lot of features are currently broken or in active development, such as federation.

## About
[Lemmy](https://github.com/dessalines/lemmy) is similar to sites like [Reddit](https://reddit.com), [Lobste.rs](https://lobste.rs), [Raddle](https://raddle.me), or [Hacker News](https://news.ycombinator.com/): you subscribe to forums you're interested in, post links and discussions, then vote, and comment on them. Behind the scenes, it is very different; anyone can easily run a server, and all these servers are federated (think email), and connected to the same universe, called the [Fediverse](https://en.wikipedia.org/wiki/Fediverse).

For a link aggregator, this means a user registered on one server can subscribe to forums on any other server, and can have discussions with users registered elsewhere.

The overall goal is to create an easily self-hostable, decentralized alternative to reddit and other link aggregators, outside of their corporate control and meddling.

Each lemmy server can set its own moderation policy; appointing site-wide admins, and community moderators to keep out the trolls, and foster a healthy, non-toxic environment where all can feel comfortable contributing.

## Why's it called Lemmy?
- Lead singer from [motorhead](https://invidio.us/watch?v=pWB5JZRGl0U).
- The old school [video game](<https://en.wikipedia.org/wiki/Lemmings_(video_game)>).
- The [Koopa from Super Mario](https://www.mariowiki.com/Lemmy_Koopa).
- The [furry rodents](http://sunchild.fpwc.org/lemming-the-little-giant-of-the-north/).

Made with [Rust](https://www.rust-lang.org), [Actix](https://actix.rs/), [Inferno](https://www.infernojs.org), [Typescript](https://www.typescriptlang.org/) and [Diesel](http://diesel.rs/).
## Install
### Docker
Make sure you have both docker and docker-compose installed.

```
git clone https://github.com/dessalines/lemmy
cd lemmy/docker
docker-compose up -d
```

and goto http://localhost:8536
## Develop
### Docker Development

```
git clone https://github.com/dessalines/lemmy
cd lemmy
./docker_update.sh # This pulls the newest version, builds and runs it
```

and goto http://localhost:8536
### Kubernetes
#### Requirements
- Local or remote Kubernetes cluster, i.e. [`minikube`](https://kubernetes.io/docs/tasks/tools/install-minikube/)
- [`kubectl`](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
- [`skaffold`](https://skaffold.dev/)
#### Production
```bash
# Deploy the Traefik Ingress
kubectl apply -f https://raw.githubusercontent.com/containous/traefik/v1.7/examples/k8s/traefik-rbac.yaml
kubectl apply -f https://raw.githubusercontent.com/containous/traefik/v1.7/examples/k8s/traefik-ds.yaml
# Replace ${IP} with your Ingress' IP
echo "${IP} dev.lemmy.local" >> /etc/hosts
```

```bash
skaffold run -p lemmy--prod
```

Now go to http://dev.lemmy.local.
#### Development
```bash
skaffold dev -p lemmy--dev
```

Now go to http://localhost:4444. It automatically proxies to localhost, both if the cluster is local or remote; it also hot-reloads the UI and automatically recompiles and restarts the server.
### Local Development
#### Requirements
- [Rust](https://www.rust-lang.org/)
- [Yarn](https://yarnpkg.com/en/)
- [Postgres](https://www.sqlite.org/index.html)
#### Set up Postgres DB
```
 psql -c "create user rrr with password 'rrr' superuser;" -U postgres
 psql -c 'create database rrr with owner rrr;' -U postgres
```
#### Running
```
git clone https://github.com/dessalines/lemmy
cd lemmy
./install.sh
# For live coding, where both the front and back end, automagically reload on any save, do:
# cd ui && yarn start
# cd server && cargo watch -x run
```

and goto http://localhost:8536
