Gaps searches through your Plex Server or local folders for all movies, then queries for known movies in the same collection. If those movies don’t exist in your library, Gaps will recommend getting those movies, legally of course. In this step by step guide I will show you how to install Gaps on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest Gaps v0.10.4 release.

• STEP 1

Please Support My work by Making a Donation.

• STEP 2

Install Container Manager via Synology “Package Center”. If you run an older DSM version (under 7.2), search for Docker instead of Container Manager.

• STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it gaps. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4

Go to Control Panel / Task Scheduler / Create / Scheduled Task / User-defined script. Follow the instructions in the images below.

• STEP 5

Once you click on User-defined script a new window will open. Follow the instructions below:

1. General: In the Task field type in Install Gaps. Uncheck “Enabled” option. Select root User.
2. Schedule: Select Run on the following date then select “Do not repeat“.
3. Task Settings: Check “Send run details by email“, add your email then copy paste the code below in the Run command area. After that click OK.

docker run -d --name=gaps \
-p 5211:8484 \
-v /volume1/docker/gaps:/usr/data \
--restart always \
--expose 32400 \
housewrecker/gaps

• STEP 6

After you click OK on STEP 5 a new warning pop up window will open. Click OK.

After you click OK, type in your DSM Password then click Submit. Follow the instructions in the image below.

• STEP 7

After you click Submit on STEP 6, select your “Install Gaps” Task then click the “Run” tab. You will be asked to run Install Gaps – click OK. Follow the instructions in the image below.

• STEP 8

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 9

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://Synology-ip-address:5211 Follow the instructions in the images below.
