DailyTxT is an encrypted Diary Web-App to write down your stories of the day and to find them again easily. It is written in Python Flask (Backend) and Vue.JS (Frontend). In this step by step guide I will show you how to install DailyTxT on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest DailyTxT 2.2.0 release.

💡Note: Check out my new guide on how to Install DailyTxT Using Portainer.

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 dailytxt. 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 image 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 DailyTxT. Uncheck the “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.

🟢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.
