It looks like it contains a bunch of hashes but i cant seem to figure out what its for.
Would there be any harm in it being lost ?
Does it contain sensitive information ?
Edit the daemon. json file, which is usually located in /etc/docker/ . You may need to create this file, if it does not yet exist.
The config can be found in /var/snap/docker/current/config/daemon. json .
The Docker daemon ( dockerd ) listens for Docker API requests and manages Docker objects such as images, containers, networks, and volumes. A daemon can also communicate with other daemons to manage Docker services.
This is the dockerd key for TLS connections, in web format, that docker uses when connecting to other TLS servers like registries. It's automatically generated by the docker engine on startup, so there's no risk if deleted. You should treat it as sensitive since TLS connections using an exposed key are not secure.
