Thanks so much. Very well done explainer. It's so much more comfortable to have a backup container while you check the update.

Used this to update pihole. Easy and straightforward, unlike the documentation which tells you to use commands of which I have no idea where to put them. I'm spending a lot of time learning anything about my NAS but I don't have time for everything! :p

One thing you need to remember when using the 'Duplicate Settings' option in Synology GUI is that it will not duplicate local port values if it's other than auto, for obvious reasons.

Another tip: If you have Enable Auto-Start turned on, when you duplicate and rename to add "-BACKUP", uncheck that setting so if your server does restart, you don't have two conflicting containers running!

I followed the first half of the video using the Docker app in Synology to rename and duplicate. The problem I ran in to is that because I assign the Local Port for my containers, when the original is duplicated, it changes Local Port to Auto. I used to just download the latest, stop, clear, and start, but I like the idea of having a backup like you mention. Just need to change the ports between the original and duplicate using your method. Thank you for the video.

@WunderTechTutorials 3 жыл бұрын

If the "clear" method works for you, feel free to keep using it! For whatever reason, I cannot get that to work at all. As soon as I clear the container, it's wipes it out and I need to start over. Wondering if there is a difference between NAS devices, but use whatever you feel most comfortable with!

Faster way to pull all the updates down via the shell: sudo docker inspect --format {{.Config.Image}} $(sudo docker ps -a --format {{.ID}}) | sudo xargs -n1 -I docker pull {} (remove the sudo statements if putting in a script, and run script as appropriate user, aka, sudo if needed) Not a docker Ninja, so there may be an even more streamlined way to pull the latest of all the installed docker images. Once the images are migrated, purge the unused images from cache: docker image prune

You will first have to mount the config location in the old container: 1. Create a folder in the docker folder on your NAS named "jellyfin", then stop the container. Create a new volume pointed to that folder you just created and use the container path "/config". I left this part out in the tutorial because I stupidly assumed that people would only care about their media data. 2. Start the container, access the jellyfin folder on your NAS and confirm there is data inside of it. If there is, move on to step 3. If not, something isn't mapped properly.

Did you double-click on the image from the registry to make sure you downloaded the newest one? Also, are you sure there's a new version? You will not be able to delete an image without removing the containers that use it. However, your goal should be to download the newest version, duplicate the settings and then delete the old container when you know it works.

The backup onee continues to allow me to access its gui but the updated version is unsuccessful even after I updated the ports to match those of the old.

Additional question: in the registry it says ":latest" (see @2:10) for both, the backup and the updated container. When I download a new image and decide to turn the backup back on again because something didnt work with the new version of the image, will it use the old image from before? Im worried it will use the most recent image because of the ":latest" tag. I want to update my 10 month old vaultwarden container and just want to make sure.

@aliasname5518 Жыл бұрын

If you select "latest" for the new image your backup will use that too, right? Therefore you'd always need to pick the specific version so that the image stays in docker, otherwise it'll just overwrite "latest" and you can't go back.

Do you have a config mount path? I should have included that in my initial instructions, but I made the assumption that most people only cared about the media and that's my fault. If you go into the old container, create a folder under the "Docker" folder named "jellyfin", then a folder inside of there named "config". Select that folder in the mount path, then map it to the "/config" location. Start the container, stop it, then mount the same path on the new container. All of your info should now be there.
