Hello,

I did my best to search for an answer to my questions in the forum and official documentation, but have not come up with any answers that are clear enough for me to understand.

Can anyone help me with the simplest non-destructive way to change the development branch of a docker container in Unraid?

In case it matters for context, I'm currently running the Default branch of the linuxserver's repository for Ombi. The current version installed through that method is 4.47.1, which is from January 5, 2025 and tagged "latest" on github. Ombi is currently on release 4.51.6 from a few weeks back, but all releases since 4.47.1 are marked "pre-release" on github. Unfortunately 4.47.1 is not compatible with their Android application due to being out-of-date, so I'd like to get my docker swapped over to the development branch, which I believe should allow me to update to the newest "Pre-release" version. But my Ombi container is fully configured and operating, so I don't want to have to start over with configuring all the settings there.

What's the best way for me to accomplish this without losing my data?

1. Always make a backup of your appdata.

2. It can be extremely risky changing the docker branch and rolling back my not always be possible due to technical reasons like one way data migrations. This is why a backup of your appdata is critical.

To make the change you simply edit the docker container template, expand to advanced view, and edit (or add) the docker branch tag to the end of the repository:

In the example below the tag is the whole part after "plex" :latest so in this case latest is the tag. You will need to figure out what tag was used and append it.

You may or may not have a tag, if you don't you will need to add the semi-colon+tag. (then click update)

If the action is unsucessful or the docker run says failed, your container will be orphaned, you will need to click on the "add container" button, click on the corresponding template, and fix it and run it again.

Here is another example with a custom tag specific for this container:

Thanks MowMDown for posting this clear and easy-to-follow information - I appreciate your guidance, clear presentation, and thoughtful consideration. In order to get the repository information for the development branch of the Ombi container I wished to modify I started then aborted the installation of a second instance, but of the development branch rather than stable, which allowed me to get the exact text of their repository information. After backing up and stopping my existing container, I updated the Repository information and then ran a check for updates and install. And that was it - I'm updated now apparently with no ill effects and able to move ahead with setting up the mobile app for my users.

Thanks again!
