# Installation

## Requirements

Any Docker-capable recent Linux box. 
I am using a fresh Ubuntu Server 22.04 on a repurposed laptop so this guide reflects it, 
but it would probably work with other distributions and different versions with a few tweaks.
I also tested this setup on a Synology DS220+ with DSM 7.0.

## Pre-Docker Steps

### OpenSSH

If not done during installation, install OpenSSH server for remote connection: `sudo apt install openssh-server`

### Static IP

Set a static IP, assuming `192.168.0.10` and using Google DNS servers:

`sudo nano /etc//netplan/00-installer-config.yaml`

```yaml
# This is the network config written by 'subiquity'
network:
  ethernets:
    enp2s0:
      dhcp4: no
      addresses:
        - 192.168.0.10/24
      gateway4: 192.168.0.1
      nameservers:
          addresses: [8.8.8.8, 8.8.4.4]
  version: 2
```

Apply the plan:

`sudo netplan apply`

You can check the server uses the right IP with `ip a`.

### Laptop Specific Configuration

If the server is installed on a laptop, you may want to disable the suspension when the lid is closed:

`sudo nano /etc/systemd/logind.conf`

Replace: 
- `#HandleLidSwitch=suspend` by `HandleLidSwitch=ignore`
- `#LidSwitchIgnoreInhibited=yes` by `LidSwitchIgnoreInhibited=no`

Then restart: `sudo service systemd-logind restart`

## Docker Setup

Install Docker by following [these instructions](https://docs.docker.com/engine/install/ubuntu/).

Then, [install Compose V2](https://docs.docker.com/compose/cli-command/#install-on-linux).

For a global installation (both your current user and `root` when using `sudo`),
copy `/usr/libexec/docker/cli-plugins` rather than `$HOME/.docker/cli-plugins/docker-compose`.

You may then run the applications with `sudo docker compose up -d`

Then, to update the Sonarr/Radarr/Prowlarr/Jellyfin base paths, please run `./update-config.sh`. 
This is only needed for the first time as it will update the application's configuration files to use the proper URL.

## NFS Share (Optional)

It is now time to share the folders to other local devices using NFS, as it is easy to set up and fast.

This can be useful to share the media folder to a local player like Kodi or computers in the local network,
but may not be necessary if Jellyfin is going to be used to access the media.

Install the NFS kernel server:

`sudo apt-get install nfs-kernel-server`

Then edit `/etc/exports` to configure your shares:

`/mnt/data/media 192.168.0.0/255.255.255.0(rw,all_squash,nohide,no_subtree_check,anonuid=1000,anongid=1000)`

This will share the `media` folder to anybody on your local network (192.168.0.x). 
I purposely left out the `sync` flag that would slow down file transfer. 
On [some devices](https://forum.kodi.tv/showthread.php?tid=343434) you may need to use the `insecure` option for the share to be available.

Restart the NFS server to apply the changes: `sudo /etc/init.d/nfs-kernel-server restart`

On other machines, you can see the shared folder by adding the following to your `/etc/fstab`:

`192.168.0.10:/mnt/data/media /mnt/nas nfs ro,hard,intr,auto,_netdev 0 0`
