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 [Motörhead](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(>=`1.24.0`) installed.
```bash
mkdir lemmy/
cd lemmy/
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/docker-compose.yml
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/.env
# Edit the .env if you want custom passwords
docker-compose up -d
```
and goto http://localhost:8536
[A sample nginx config](/ansible/templates/nginx.conf), could be setup with:
```bash
wget https://raw.githubusercontent.com/dessalines/lemmy/master/ansible/templates/nginx.conf
# Replace the {{ vars }}
sudo mv nginx.conf /etc/nginx/sites-enabled/lemmy.conf
```
#### Updating
To update to the newest version, run:
```bash
wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/docker-compose.yml
docker-compose up -d
```
### Ansible
First, you need to [install Ansible on your local computer](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html),
eg using `sudo apt install ansible`, or the equivalent for you platform.
Then run the following commands on your local computer:
```bash
git clone https://github.com/dessalines/lemmy.git
cd lemmy/ansible/
cp inventory.example inventory
nano inventory # enter your server, domain, contact email
ansible-playbook lemmy.yml --become
```
### Kubernetes
You'll need to have an existing Kubernetes cluster and [storage class](https://kubernetes.io/docs/concepts/storage/storage-classes/).
Setting this up will vary depending on your provider.
To try it locally, you can use [MicroK8s](https://microk8s.io/) or [Minikube](https://kubernetes.io/docs/tasks/tools/install-minikube/).
Once you have a working cluster, edit the environment variables and volume sizes in `docker/k8s/*.yml`.
You may also want to change the service types to use `LoadBalancer`s depending on where you're running your cluster (add `type: LoadBalancer` to `ports)`, or `NodePort`s.
By default they will use `ClusterIP`s, which will allow access only within the cluster. See the [docs](https://kubernetes.io/docs/concepts/services-networking/service/) for more on networking in Kubernetes.
**Important** Running a database in Kubernetes will work, but is generally not recommended.
If you're deploying on any of the common cloud providers, you should consider using their managed database service instead (RDS, Cloud SQL, Azure Databse, etc.).
Now you can deploy:
```bash
# Add `-n foo` if you want to deploy into a specific namespace `foo`;
# otherwise your resources will be created in the `default` namespace.
kubectl apply -f docker/k8s/db.yml
kubectl apply -f docker/k8s/pictshare.yml
kubectl apply -f docker/k8s/lemmy.yml
```
If you used a `LoadBalancer`, you should see it in your cloud provider's console.
## Develop
### Docker Development
```bash
git clone https://github.com/dessalines/lemmy
cd lemmy/docker/dev
./docker_update.sh # This builds and runs it, updating for your changes
```
and goto http://localhost:8536
### Local Development
#### Requirements
- [Rust](https://www.rust-lang.org/)
- [Yarn](https://yarnpkg.com/en/)
- [Postgres](https://www.postgresql.org/)
#### Set up Postgres DB
```bash
psql -c "create user lemmy with password 'password' superuser;" -U postgres
psql -c 'create database lemmy with owner lemmy;' -U postgres
export DATABASE_URL=postgres://lemmy:password@localhost:5432/lemmy
```
#### Running
```bash
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
```
