Recovery from $docker save

support

Hi,
Please tell me how to restore the discourse with a backup of the docker backup.

docker save -o container-file-name.tar containername

When I try to rebuild it, I get it:

Already up-to-date.
I, [2019-06-11T20:14:10.852580 #14]  INFO -- : Loading --stdin
/pups/lib/pups/config.rb:23:in `initialize': undefined method `[]' for nil:NilClass (NoMethodError)
	from /pups/lib/pups/cli.rb:27:in `new'
	from /pups/lib/pups/cli.rb:27:in `run'
	from /pups/bin/pups:8:in `<main>'

I don’t have any other archives or backups, just this archive.
Please tell me where in this archive there is a database and related files.

That won’t work. docker save only stores the docker image, and all the stuff you want to backup (posts, users, uploads) are stored outside the image, in the mounted volumes.

I’m afraid you lost all data them :frowning:

Many thanks for the quick response, I will try to google cache.

Just to make sure. You don’t have the contents of

/var/discourse/shared

?

It was empty.
I unzipped all layers and searched with ack, my data, everything I found the logs.
Great lesson on why I need to make backups :slight_smile:
