Synology¶
Note
Being I don't have a Synology myself and I kind of hate the Synology GUI for the dockers, I'm doing this with the use of docker-compose through a terminal.
This is faster then the GUI and after installing, it shows up in the Docker GUI.
Thanks to faxity for the initial compose that I used to create the Synology Guide.
And a very big thanks to Bokkoman and BZwart that updated this Guide for DSM 7 and also offered their help on discord as Synology Support Team.
Introduction¶
This page will provide you with guidance on how to install several Docker images to your Synology system. We highly recommend to read the full guide, that way you have a better understanding of what you do, in case you later decide to make changes.
Automated Script¶
Automated script (
Use this script at your own risk) - [CLICK TO EXPAND]
Warning
Though, we offer a short way out. This is intended as a quick way to do everything that is written on this page within one script.
The script is new and only tested on Synology DSM7.
We are not held reliable if anything breaks on your system. Use at your own risk
To get this working you will need to enable terminal access (SSH).
To enable this on your Synology take a look HERE.
When you enabled the terminal access (SSH) run the following commands and follow the onscreen questions.
curl -sL git.io/syno-script > ~/syno-script
sudo bash ~/syno-script
Install Docker¶
You need to install Docker from the Package Center. This should also create a share named docker, check File Station if it is present.
Create the main share¶
Attention
To get Hardlinks and Atomic-Moves working with your Synology you will need to make use of ONE share with subfolders.
We will use a new share named data (lowercase) for all your library media.
Later in this guide, we will fill this share with subfolders.
To create a new share:
Control Panel > Shared Folder > click Create > choose Create Shared Folder
Name this shared folder data. You can disable the trash can. Click next until you are done.
Create a user¶
For this, we are going to create a new user that only has access to the share(s) that we use for this guide.
Go to Control Panel > User & Group
In the User section, create a new user. Name it whatever you like, but for this guide we will use docker.
Fill out the rest of the information, generate a password or type your own.
Click next, you will now be able to select which group this user will belong to, it should only be users. Click Next.
Assign shared folder permissions¶
In this screen you will be able to select which Shares this user will have access to, click No Access on the top, this will deny all access.
Now only select Read/Write on the shares docker and data.
Click Next until you reach Assign application permissions
Assign application permissions¶
In this screen you will be able to select which application this user will have access to, Check Deny for all applications.
Continue to click Next until you are finished.
SSH¶
You are mostly going to use the terminal. Some parts will need the Synology web GUI. To enable terminal, you need to enable SSH in the Synology Settings.
Control Panel > Terminal & SNMP > Enable SSH service
Then use a program like Putty and you can SSH into your Synology.
If you get a popup asking if you want to trust the key,
Just press OK or ACCEPT
Enter the login information of your main Synology user account.
PUID and PGID¶
In order for the Docker container to access the shares on the Synology, we need to know the user ID (PUID) and group ID (PGID) from the docker user we just created.
Go into your terminal app, login to your synology ssh.
Once logged in type id $user. Change $user to the newly created username docker.
This will show you the UID (aka PUID).
Which in this screenshot is 1035 for the docker user
and the GID (aka PGID) which is 100 for the users group.
Remember these values for later use.
Attention
It is not recommended to use (anymore) your admin/main user account. That is why we just created a new user.
Folder Structure¶
For this example we're going to make use of the share called data.
On the host (Synology) terminal you will need to add /volume1/ before it. So /volume1/data
The data folder has sub-folders for torrents and usenet and each of these have sub-folders for tv, movie and music downloads to keep things neat. The library folder has nicely named tv, movies and music sub-folders, this is your library and what you’d pass to Plex, Emby or JellyFin.
These subfolders you need to create your self.
I'm using lower case on all folder on purpose, being Linux is case sensitive.
data
├── torrents
│ ├── movies
│ ├── music
│ └── tv
├── usenet
│ ├── movies
│ ├── music
│ └── tv
└── media
├── movies
├── music
└── tv
Breakdown of the Folder Structure¶
Torrent clients¶
qBittorrent, Deluge, ruTorrent
The reason why we use /data/torrents for the torrent client is because it only needs access to the torrent files. In the torrent software settings, you’ll need to reconfigure paths and you can sort into sub-folders like /data/torrents/{tv|movies|music}.
data
└── torrents
├── movies
├── music
└── tv
Usenet clients¶
NZBGet or SABnzbd
The reason why we use /data/usenet for the usenet client is because it only needs access to the usenet files. In the usenet software settings, you’ll need to reconfigure paths and you can sort into sub-folders like /data/usenet/{tv|movies|music}.
data
└── usenet
├── movies
├── music
└── tv
The arr(s)¶
Sonarr, Radarr and Lidarr
Sonarr, Radarr and Lidarr gets access to everything because the download folder(s) and media folder will look like and be one file system. Hard links will work and moves will be atomic, instead of copy + delete.
data
├── torrents
│ ├── movies
│ ├── music
│ └── tv
├── usenet
│ ├── movies
│ ├── music
│ └── tv
└── media
├── movies
├── music
└── tv
Media Server¶
Plex, Emby, JellyFin and Bazarr
Plex, Emby, JellyFin and Bazarr only needs access to your media library, which can have any number of sub folders like Movies, Kids Movies, TV, Documentary TV and/or Music as sub folders.
data
└── media
├── movies
├── music
└── tv
Don't forget to look at the Examples how to setup the paths inside the applications.
Create the needed subfolder¶
Here we will create the needed subfolders for your media library and also for your preferred download client. If you use both then run both commands
If you use usenet¶
sudo mkdir -p /volume1/data/{usenet/{tv,movies,music},media/{tv,movies,music}}
If you use torrents¶
sudo mkdir -p /volume1/data/{torrents/{tv,movies,music},media/{tv,movies,music}}
Appdata¶
Your appdata will be stored in /volume1/docker/appdata/{appname}
These {appname} sub folders you need to create your self. (This is a limitation of the Synology)
We're going to do this in Putty or a similar program.
sudo mkdir -p /volume1/docker/appdata/{radarr,sonarr,bazarr,plex,pullio}
You can add your own sub folders for your download client(s) using the command above, by adding the name to the command.
So your appdata folder will look like this.
ls -al /volume1/docker/appdata
docker
└── appdata
├── radarr
├── sonarr
├── bazarr
├── plex
├── pullio
└── (your download client, i.e. nzbget; sabnzbd; qbittorrent)
Needed files¶
Now we are ready to move to the installation of containers.
For this, we need two files:
docker-compose.yml.env
We will start with downloading the docker-compose.yml file
Download this docker-compose.yml to your /volume1/docker/appdata location so you got your important stuff together. Or use the command below:
sudo wget https://raw.githubusercontent.com/TRaSH-/Guides-Synology-Templates/main/docker-compose/docker-compose.yml -P /volume1/docker/appdata/
Whats included and Whats not included¶
What's included and What's not included - [CLICK TO EXPAND]
This docker-compose file will have the following docker containers included.
- Radarr
- Sonarr
- Bazarr (Subtitle searcher and downloader)
- Plex
What's not included (and where are the download clients?).
I didn't add a download client to it, because it depends on what you prefer (usenet/torrent) and which client you prefer, so I created a new Repository on Github where I provide and maintain some templates that are ready to use with the main docker-compose.yml.
The only thing you need to do is copy/paste what's inside the .yml file in to the main docker-compose.yml, the template also has the command what you need to use to create the appdata folder that we explained earlier.
Second we will download the .env file
Download this .env to your /volume1/docker/appdata location so you got your important stuff together. Or use this command:
sudo wget https://raw.githubusercontent.com/TRaSH-/Guides-Synology-Templates/main/docker-compose/.env -P /volume1/docker/appdata/
Attention
MAKE SURE THE FILE KEEPS THE ORIGINAL NAME .env WITH THE DOT BEFORE IT
Changes and preparations¶
Tip
If you need to edit docker-compose.yml or the .env file we advise to use Notepad++ or Visual Studio Code
The .env file we downloaded holds the variables/information you need to change in order for everything to work. I added explanations in the .env file.
- DOCKERCONFDIR (only change this if you know what you're doing and decide to use another path than this guide used)
- DOCKERDATADIR (only change this if you know what you're doing and decide to use another path than this guide used)
- PUID/PGID (this info you got earlier from HERE
- TZ (Change to your timezone, can be found HERE
- Install and Create a task scheduler for Pullio, so your containers stay up to date.
The .env holds more variables/information for other containers you don't need to remove those variables and will be only used when you install the other containers.
Pullio - Auto update docker-compose the correct way¶
Pullio allows you to automatically update your containers. And send you a notification through various means. In my setup, I use a Discord Webhook.
First you need to download Pullio
sudo curl -fsSL "https://raw.githubusercontent.com/hotio/pullio/master/pullio.sh" -o /usr/local/bin/pullio
sudo chmod +x /usr/local/bin/pullio
For Pullio to work, you will need to create in your Task Scheduler a "Scheduled Task" that runs for example at 4am at night with root privileges.
Control Panel > Task Scheduler > click Create > choose Scheduled task - user defined script
Give the task a name so you know what it does. Choose user root.
In the Schedule tab choose whenever you want it to check for updates.
At Task Settings tab, add the following line in the Run Command section:
/usr/local/bin/pullio > /volume1/docker/appdata/pullio/pullio.log 2>&1
It can be frustrating to test the script if no docker image updates are available, for that you can run command sudo pullio --debug and the script will behave as if an update is available. If you have set to receive notifications, you should receive them.
More info about Pullio HERE
Permissions¶
Now we need to make sure that the newly created files and folders have the correct permissions.
Note
If you're using a different user than docker (the user generated in the beginning), then you need to change the docker:users part in the commands below!!!
sudo chown -R docker:users /volume1/data /volume1/docker
sudo chmod -R a=,a+rX,u+w,g+w /volume1/data /volume1/docker
Note
If you copy files from a different library into the newly created library, you need to rerun these commands. !!!
Run the Docker Compose¶
Important
make sure you delete/remove all your existing dockers from the Docker GUI and also remove your native installs (in Package Center) of these applications !!! If you had previous installed apps, make a backup of their config folders.
When you did all the above steps you only need to run the following commands:
cd /volume1/docker/appdata
sudo docker-compose up -d
You will notice that all the images will be downloaded, after that the containers will be started. If you get a error then look at the error what it says and try to fix it. If you still got issues then put your used docker-compose.yml on 0bin and join the guides-discord here and provide the pastebin link with the error, have patience because of timezone differences.
Don't forget to look at the Examples how to setup the paths inside your applications.
Attention
If you need to do any changes, only edit the docker-compose.yml file. To activate the changes, run the command sudo docker-compose -f /volume1/docker/appdata/docker-compose.yml up -d again.
Any changes you do/did in the GUI will be reverted when you run the docker-compose command.
Just don't use the GUI, only for information purposes !!!
Docker-Compose Commands¶
docker-compose commands - [CLICK TO EXPAND]
sudo docker-compose up -d(This Docker-compose command helps builds the image, then creates and starts Docker containers. The containers are from the services specified in the compose file. If the containers are already running and you run docker-compose up, it recreates the container.)sudo docker-compose pull(Pulls an image associated with a service defined in a docker-compose.yml)sudo docker-compose down(The Docker-compose down command also stops Docker containers like the stop command does. But it goes the extra mile. Docker-compose down, doesn’t just stop the containers, it also removes them.)sudo docker system prune -a --volumes --force(Remove all unused containers, networks, images (both dangling and unreferenced), and optionally, volumes.)
