- Annoyance
[BACKGROUND:]
I would call this an edge-case, and just annoyance level of a bug - however I found this to be very annoying when caught in it. The Unraid webui, TOWER/Docker/, can be thrown into a refresh-loop - causing a number of page functions to stop working, or greyed-out, while the UI waits for the loop/task to stop. This was found trying to setup a VPN-client container and pointing a Torrent client container to the VPN container.
[ISSUE:]
When a Docker container fails to be edited/created (the container becomes orphaned) - expected behavior. If a container is linked to another container, such as using 'extra parameter' "--net=container:nordvpn" that container becomes dependent on the linked container - expected behavior. If the required container is edited/updated the other container also updates - expected behavior.
If the required-container is edited incorrectly and fails creation/update the container becomes orphaned; Docker/webui notices the dependency-container has changed and attempts to update other container. However the second container fails to update, because the dependency-container has been orphaned - The Unraid Webui gets stuck in a loop trying to rebuild the container.
Only way I found to stop this loop is to try and remove the second container; afterwards hit refresh button on web browser; and then remake both containers. On two occasions I was unable to remove the second container, and had to go into Settings and stop/start Docker completely.
[STEPS TO REPRODUCE ISSUE:]
0* From APP store-plugin grab:
nordvpn
transmission
1* Per instructions from nordvpn - Overview: https://www.youtube.com/watch?v=znSu_FuKFW0
* Edit Transmission container settings:
* Disabled network
* 'Extra Parameters:' == '--net=container:nordvpn'
* APPLY (webui)
2* Edit Nordvpn container
* Make a change and save which will cause an error in updating/rebuilding the container and cause the container image to orphan (I did this as I was trying things to troubleshoot and get VPN-bittorrent to actually work).
Example to cause container update failure: 'Extra Parameters:' == '--device /dev/net/tun --cap-add=NET_ADMIN,SYS_ADMIN'
* APPLY (webui)
The update to Nordvpn should have failed; taking user back to TOWER/Docker where the system attempts to rebuild Transmission and is stuck in a loop. This loop continues until the user removes the Transmission container, and hits the refresh button in web browser.
--EOF
I hope I outlined the issue enough to be useful, if there's something which needs better explanation let me know.
Please move this post if it's in the wrong thread.
Have a good one everyone!
