SSH Keys¶
Ganeti Web Manager allows users to store SSH Keys. Each virtual machine has a view that will return SSH keys for users with access.
Configuring User SSH Keys¶
As an User¶
- click your username in the menu sidebar
- use the Add, Edit, and Delete buttons to manage your keys
As an Admin¶
- click Users in the menu sidebar
- click the edit button for the user you want to edit
- use the Add, Edit, and Delete buttons to manage your keys
SSH Keys script¶
Ganeti Web Manager provides a script that will automatically generate an authorized_keys files
$ python util/sshkeys.py [-c CLUSTER [-i INSTANCE]] WEB_MGR_API_KEY URL
- WEB_MGR_API_KEY is the value set in
config.yml
settings file - URL is a URL pointing to the GWM server
- CLUSTER is the identifier of a cluster
- INSTANCE is the hostname of an instance
The GWM server URL has some flexibility in how it may be specified; HTTP and HTTPS are supported, as well as custom port numbers. The following are all valid URLs:
CLUSTER and INSTANCE are optional. Including them will narrow the list of users to either a Cluster or a VirtualMachine.
SSH Keys Ganeti hook¶
If you want your VMs to automatically copy the ssh keys from GWM, then you can
use the included ssh keys ganeti hook found in util/hooks/sshkeys.sh
. Copy
that file onto every node in your cluster in the hooks directory for the
instance definition you’re using (i.e. ganeti-debootstrap). Copy and set the
variables in util/hooks/sshkeys.conf
into the variant config and/or the
instance definition config file. Make sure that the hook is executable and
all the variables are set include changing the API Key.
