Vikunja is an open source, selfhosted application. With Vikunja you can easily organize all of your tasks in lists. Put lists together in a namespace to keep related stuff grouped together. Vikunja lets you easily share a list or a namespace with another user or a whole team! You can also assign tasks to people so everybody knows who’s working on what. In this step by step guide I will show you how to install VikunjaĀ on yourĀ UGREEN NAS using Docker and Portainer.
STEP 1
Please Support My work by Making a Donation.
STEP 2
InstallĀ Portainer using my step by step guide. If you already have Portainer installed on your UGREEN NAS, skip this STEP. Attention: Make sure you have installed the latest Portainer version.
STEP 3
ā ļøMandatory: Enable HTTPS on your UGREEN NAS.
STEP 4
Create a new hostname on the noip website using your noip account. For example, I have created vikmariusĀ as Host and I use the free ddns.net domain. In the IP Address area, type in your own IPV4 IP address from your ISP, then click Create. Follow the instructions in the image below.

ā ļøMandatory: Add Read & Write Permissions to the Docker Folder.
STEP 6

STEP 7
Now create two new folders inside the vikunja folder that you have previously created at STEP 6 and name them dataĀ and db. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

STEP 8
Follow my step by step guide on how to activate SMTP for your Gmail account. This step is mandatory. Note: If you don’t want to use the easiest way for SMTP with Google and you already have SMTP details from your own Mail Server, you can just skip this STEP and use your personalized email SMTP details instead.
