How to Install Gitea on Your UGREEN NAS

Gitea is a free, open-source, self-hosted Git service designed as a lightweight and user-friendly alternative to platforms like GitHub or GitLab. It provides a platform for hosting Git repositories, along with features for code review, team collaboration, and CI/CD. Essentially, it’s a complete DevOps platform for managing software development projects. In this step by step guide I will show you how to install Gitea on your UGREEN NAS using Docker and Portainer.

💡Note: This guide works perfectly with the latest Gitea v1.24.2 release.

💡Note: Check out my guide on how to Install Gitea on Your Synology NAS.

  • STEP 2

Install 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

⚠️Mandatory: 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 mariusgitea as hostname 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/Add Hostname. Follow the instructions in the image below.

🟢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.
