Fix to a small issue with updating OCI docker images

[m33ts4k0z]

Hello,

 

I came across a small issue regarding the version status of an image that apparently was in OCI format. Unraid wasn't able to get the manifest information file because of wrong headers. As a result, checking for updates showed "Not available" instead. The docker image is the linuxGSM docker container and the fix is really simple. 

 

This is for Unraid version 6.11.5 but it will work even for older versions if you find the corresponding line in that file.

 

SSHing into the Unraid server, in file:

/usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php

change line 448 to this:

$header = ['Accept: application/vnd.docker.distribution.manifest.list.v2+json,application/vnd.docker.distribution.manifest.v2+json,application/vnd.oci.image.index.v1+json'];

And the version check worked after that.

 

I suppose this change will be removed upon server restart but it will be nice if you can include it on the next Unraid update 😊

 

Thanks

I get Permission denied when I SSH in and try to access that file. How do I get access to the file?

I used the Unraid terminal to change to the correct directory then used the nano text editor to update the file.

Could you post what line 448 looks like prior to the above update?  I'm running 6.9.2 and I'm wanting to make sure I'm touching the correct line.  My current line 448 reads:

$reply_json = json_decode($reply, true);

 

Seems like a really radical update if that's what I'm supposed to be replacing.

 

More and more of my dockers have gone "not available" in the past week, for reasons I'm unaware of.  I'm hoping that this might fix it.  TIA

ETA: I'm also not opposed to upgrading to 6.10 or 6.11 if one or the other will resolve this.  Thx again.

I still get permission denied. It's really weird.

This is for Unraid version 6.11.5. the line looks the same but without the

,application/vnd.oci.image.index.v1+json'

Im not sure how this line looks like on 6.10 but if you could find:

$header = ['Accept: application/vnd.docker.distribution.manifest.list.v2+json,application/vnd.docker.distribution.manifest.v2+json'];

Just append it after:

 

,application/vnd.docker.distribution.manifest.v2+json

The command you need is as follows:

nano /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php

 

You can also use WinSCP if you are on Windows. Choose SCP protocol and connect to the same port as SSH.

Thank you. I can finally update my docker containers now!

Thanks. Was getting "Not available" for Dozzle and this fixed it.

The Unraid webgui is actually open source, since you found the solution if you are interested you can submit a PR here:

Thanks for this. You saved me some time. The PR is already accepted and the fix is applied on github.

Will it be updated with unraid or with AppStore plug-in thing in unraid?

It will be updated when the next core update for Unraid releases. Unraid is currently on version 6.11.5. The next version will most likely include this fix.

Thanks, I'll take a look at it.

 

Do you (or anyone) know why this has become an issue all of a sudden?  Just curious.

Thanks again.
