Prerequisites

Before you get started with the Open WebUI AMI, ensure you have the following prerequisites:

Launching the AMI

Step 1: Find and Select ''Open WebUI'' AMI

3. Add the record name and then paste the copied "PublicIp" into the "value" textbox.

4. Click "Save".

Access Open WebUI

You can set up the Open Web UI application through the "DashboardUrl" or "DashboardUrlIp" provided in the "Outputs" tab. This will allow you to create an Admin account, and all future accounts will be created through the Admin panel.

(If you encounter a "502 Bad Gateway error", please wait for about 5 minutes before refreshing the page)

Enter all the required details and click on the “Create Account” button.

Important: You are now creating the Admin Account for your Open WebUI deployment. The email address and password you provide here will be used to manage your entire workspace including inviting team members, configuring system settings, and maintaining overall access.

Make sure to choose a strong password and store your credentials securely, as they are critical for future access and team management.

Generate SSL Manually

Open WebUI will automatically try to setup SSL based on provided domain name, if that domain hosted on Route53. If its unsuccessful then you have to setup SSL manually.

  2. Paste the following command into your terminal and press Enter:
ssh -i <your key name> ubuntu@<Public IP address>

3. Type "yes" and press Enter. This will log you into the server.

Step3: Generate SSL

Paste the following command into your terminal and press Enter, and follow the instructions

sudo /root/certificate_generate_standalone.sh

Admin Email is acquiring for generate SSL certificates.

Step1: Log in to the server

  1. Open the terminal and go to the directory where your private key is located.
  2. Paste the following command into your terminal and press Enter:

3. Type "yes" and press Enter. This will log you into the server.

Step2: Check the logs

Select the correct container and check logs

sudo docker logs d1
sudo docker logs 43

Shutting Down Open WebUI

Remove Open Web UI

Delete the stack that has been created in the AWS Management Console under 'CloudFormation Stacks' by clicking the 'Delete' button.

Upgrades

When there is an upgrade, we will update the product with a newer version. You can check the product version in AWS Marketplace. If a newer version is available, you can remove the previous version and launch the product again using the newer version. Remember to backup the necessary server data before removing.


Troubleshoot

  1. If you face the following error, please follow https://meetrix.io/articles/how-to-increase-aws-quota/ blog to increase vCPU quota.

2. If you face the following error (do not have sufficient <instance_type> capacity...) while creating the stack, try changing the region or try creating the stack at a later time.

3. If you face the below error, when you try to access the API dashboard, please wait 5-10 minutes and then try.

4. Check whether the instance storage is full.

  • Log into the server and run the below command

                                                                 df -h

                                                             root volume

  • If the root volume is between 90-100%, it is better to resize EBS volume. Please follow AWS documentation to increase the EBS volume.
  • Then reboot the instance and restart the Open Web UI service.
