## 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/lemmy.hjson
|
|
# Edit the .env if you want custom passwords
|
|
docker-compose up -d
|
|
```
|
|
|
|
and go to 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) (e.g. 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
|
|
|
|
Run:
|
|
|
|
```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 go to 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
|
|
```
|
|
|
|
## Configuration
|
|
|
|
The configuration is based on the file [defaults.hjson](server/config/defaults.hjson). This file also contains documentation for all the available options. To override the defaults, you can copy the options you want to change into your local `config.hjson` file.
|
|
|
|
Additionally, you can override any config files with environment variables. These have the same name as the config options, and are prefixed with `LEMMY_`. For example, you can override the `database.password` with
|
|
`LEMMY__DATABASE__POOL_SIZE=10`.
|
|
|
|
An additional option `LEMMY_DATABASE_URL` is available, which can be used with a PostgreSQL connection string like `postgres://lemmy:password@lemmy_db:5432/lemmy`, passing all connection details at once.
