  94 ## About
  95
  96 [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).
  97
  98 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.
  99
 100 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.
 101
 102 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.
 103
 104 ### Why's it called Lemmy?
 105
 106 - Lead singer from [Motörhead](https://invidio.us/watch?v=pWB5JZRGl0U).
 107 - The old school [video game](<https://en.wikipedia.org/wiki/Lemmings_(video_game)>).
 108 - The [Koopa from Super Mario](https://www.mariowiki.com/Lemmy_Koopa).
 109 - The [furry rodents](http://sunchild.fpwc.org/lemming-the-little-giant-of-the-north/).
 110
 111 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/).
 112
 113 ## Install
 114
 115 ### Docker
 116
 117 Make sure you have both docker and docker-compose(>=`1.24.0`) installed:
 118
 119 ```bash
 120 mkdir lemmy/
 121 cd lemmy/
 122 wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/docker-compose.yml
 123 wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/lemmy.hjson
 124 # Edit the .env if you want custom passwords
 125 docker-compose up -d
 126 ```
 127
 128 and go to http://localhost:8536.
 129
 130 [A sample nginx config](/ansible/templates/nginx.conf), could be setup with:
 131
 132 ```bash
 133 wget https://raw.githubusercontent.com/dessalines/lemmy/master/ansible/templates/nginx.conf
 134 # Replace the {{ vars }}
 135 sudo mv nginx.conf /etc/nginx/sites-enabled/lemmy.conf
 136 ```
 137 #### Updating
 138
 139 To update to the newest version, run:
 140
 141 ```bash
 142 wget https://raw.githubusercontent.com/dessalines/lemmy/master/docker/prod/docker-compose.yml
 143 docker-compose up -d
 144 ```
 145
 146 ### Ansible
 147
 148 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.
 149
 150 Then run the following commands on your local computer:
 151
 152 ```bash
 153 git clone https://github.com/dessalines/lemmy.git
 154 cd lemmy/ansible/
 155 cp inventory.example inventory
 156 nano inventory # enter your server, domain, contact email
 157 ansible-playbook lemmy.yml --become
 158 ```
 159
 160 ### Kubernetes
 161
 162 You'll need to have an existing Kubernetes cluster and [storage class](https://kubernetes.io/docs/concepts/storage/storage-classes/).
 163 Setting this up will vary depending on your provider.
 164 To try it locally, you can use [MicroK8s](https://microk8s.io/) or [Minikube](https://kubernetes.io/docs/tasks/tools/install-minikube/).
 165
 166 Once you have a working cluster, edit the environment variables and volume sizes in `docker/k8s/*.yml`.
 167 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.
 168 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.
 169
 170 **Important** Running a database in Kubernetes will work, but is generally not recommended.
 171 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.).
 172
 173 Now you can deploy:
 174
 175 ```bash
 176 # Add `-n foo` if you want to deploy into a specific namespace `foo`;
 177 # otherwise your resources will be created in the `default` namespace.
 178 kubectl apply -f docker/k8s/db.yml
 179 kubectl apply -f docker/k8s/pictshare.yml
 180 kubectl apply -f docker/k8s/lemmy.yml
 181 ```
 182
 183 If you used a `LoadBalancer`, you should see it in your cloud provider's console.
 184
 185 ## Develop
 186
 187 ### Docker Development
 188
 189 Run:
 190
 191 ```bash
 192 git clone https://github.com/dessalines/lemmy
 193 cd lemmy/docker/dev
 194 ./docker_update.sh # This builds and runs it, updating for your changes
 195 ```
 196
 197 and go to http://localhost:8536.
 198
 199 ### Local Development
 200
 201 #### Requirements
 202
 203 - [Rust](https://www.rust-lang.org/)
 204 - [Yarn](https://yarnpkg.com/en/)
 205 - [Postgres](https://www.postgresql.org/)
 206
 207 #### Set up Postgres DB
 208
 209 ```bash
 210  psql -c "create user lemmy with password 'password' superuser;" -U postgres
 211  psql -c 'create database lemmy with owner lemmy;' -U postgres
 212  export DATABASE_URL=postgres://lemmy:password@localhost:5432/lemmy
 213 ```
 214
 215 #### Running
 216
 217 ```bash
 218 git clone https://github.com/dessalines/lemmy
 219 cd lemmy
 220 ./install.sh
 221 # For live coding, where both the front and back end, automagically reload on any save, do:
 222 # cd ui && yarn start
 223 # cd server && cargo watch -x run
 224 ```
 225
 226 ## Configuration
 227
 228 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.
 229
 230 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
 231 `LEMMY__DATABASE__POOL_SIZE=10`.
 232
 233 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.
 234
