When using LXD over https, LXD uses an asymmetric keypair for authentication. The keypairs are added to the authentication database after entering the LXD instance’s “trust password”.
Generate a certificate¶
To generate a keypair, you should use the openssl command. As an example:
openssl req -newkey rsa:2048 -nodes -keyout lxd.key -out lxd.csr openssl x509 -signkey lxd.key -in lxd.csr -req -days 365 -out lxd.crt
For more detail on the commands, or to customize the keys, please see the documentation for the openssl command.
Authenticate a new keypair¶
If a client is created using this keypair, it would originally be “untrusted”, essentially meaning that the authentication has not yet occurred.
>>> from pylxd import Client >>> client = Client( ... endpoint='http://10.0.0.1:8443', ... cert=('lxd.crt', 'lxd.key')) >>> client.trusted False
In order to authenticate the client, pass the lxd instance’s trust password to Client.authenticate
>>> client.authenticate('a-secret-trust-password') >>> client.trusted >>> True
