Please provide LXD server URL: https://ikoulaf.appgv.com:8443
Certificate fingerprint: 7843bcb8cb...
ok (y/n)? y

1) Use a certificate token
2) Use an existing TLS authentication certificate
3) Generate a temporary TLS authentication certificate
Please pick an authentication mechanism above: 3

Your temporary certificate is:
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----

It is recommended to have this certificate be manually added to LXD through `lxc config trust add` on the target server.
Alternatively you could use a pre-defined trust password to add it remotely (use of a trust password can be a security issue).

Would you like to use a trust password? [default=no]:
Press ENTER after the certificate was added to the remote server:

Remote LXD server:
  Hostname: ikoulaf
  Version: 5.3

Would you like to create a container (1) or virtual-machine (2)?: 1
Name of the new instance: contabob
Please provide the path to a root filesystem: /
Do you want to add additional filesystem mounts? [default=no]:

Instance to be created:
  Name: contabob
  Project: default
  Type: container
  Source: /

Additional overrides can be applied at this stage:
1) Begin the migration with the above configuration
2) Override profile list
3) Set additional configuration options
4) Change instance storage pool or volume size
5) Change instance network

Please pick one of the options above [default=1]:
Transferring instance: contabob: 1.39GB (6.05MB/s)
