This commit adds a command to generate a private key for headscale.
Mostly useful for systems were you drive the deployment from another
machine and use a secret management system.
This commit converts all the uses of wgkey to the new key interfaces.
It now has specific machine, node and discovery keys and we now should
use them correctly.
Please note the new logic which strips a key prefix (in utils.go) that
is now standard inside tailscale.
In theory we could put it in the database, but to preserve backwards
compatibility and not spend a lot of resources on accounting for both,
we just strip them.
a nil value, instead of the default value (1h). This resulted in the
preauthkey being created with expiration key '0001-01-01 00:00:00',
which meant the key would not work, because it was already expired.
This commit applies the default expiration time (1h) when a preauthkey
is created without a specific expiration. It also updates an integration
test to make sure this bug does not reoccur.
This commit is trying to DRY up the initiation of the gRPC client in
each command:
It renames the function to CLI instead of GRPC as it actually set up a
CLI client, not a generic grpc client
It also moves the configuration of address, timeout (which is now
consistent) and api to use Viper, allowing users to set it via env vars
and configuration file
This commit is a first in a series of commits migrating the command
interfaces to use the new gRPC client.
As a part of this commit, they have been streamlined and each command
_should_ be a bit more similar and use consistent output.
By using the new output function, we now make sure its always json
(errors and everything) if the user asks for JSON.
