OpenCloud is a modern, open-source, self-hosted platform for file management, secure sharing, and team collaboration. It prioritizes simplicity and data sovereignty, giving users full control without unnecessary complexity. In this step by step guide I will show you how to install OpenCloud on your UGREEN NAS using Docker and Portainer.

💡Note: This guide works perfectly with the latest OpenCloud v5.0.2 release.

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

• STEP 1

Please Support My work by Making a Donation.

• 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 mariuscloud 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.

• STEP 5

⚠️Mandatory: Add Read & Write Permissions to the Docker Folder.

• STEP 6

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

• STEP 7

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

• STEP 8

Log into Portainer using your username and password. On the left sidebar in Portainer, click on Home then Live connect. 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.
