Once you have the keys set up in Morpheus, you can arrange for them to be added to new VMs when they are provisioned (last step below) - note that updating these keys or adding them to existing machines needs to be done manually.
For new VMs, only the keys of the person creating the VM will be added. You have to add any other users manually.

If an LDAP server was provided as part of your tenancy (an option, typically default for EUMETSAT-homed tenancies), you may prefer to add the keys to the LDAP server instead - they will then work on all machines (already provisioned or future ones) and can be updated at any time. This section is just about "local" Morpheus-created users. Here's the Getting Started for EUMETSAT tenancies: EUMETSAT tenancy: Default setup |

Creating the keys
You will need to create a key pair if you don't have an existing key pair already. If you do, then see below.
...
This creates a key pair in "PEM" format, as required by Morpheus, using the RSA algorithm (elliptic curves seem not to be supported yet).
Converting existing keys
Note that it's often good practice to use different credentials for different services, so you may want to create a new key pair instead of reusing existing ones.
...
For non-OpenSSH formats or clients, please search for an appropriate conversion mechanism or contact EWC support for help.
Adding the keys in Morpheus
- Go to Infrastructure -> Trust -> Key Pairs.
- Click the + ADD button
As options you can select alternatively:
- select "Existing Key Pair" if you you have already your keys pairs
or
- select "Generate Key Pair" if you want to let Morpheus to generate a key pair (private and public keys) for you. In this case save the generated private key.
- When importing an "Existing Key Pair" the following screen should appear:
- Give a meaningful name to the key, such as your username.
- You can leave the public key field blank - Morpheus will fill this automatically by (re)generating it from the private key.
Browse for the private key, or paste its contents. For OpenSSH, it should normally be stored in:
No Format ~/.ssh/id_rsa
- If your private key requires a passphrase, add it into the relevant text box.
- Save changes
Updating User Settings
Now that your keys are added into Morpheus, you may also configure your user profile so the keys are injected automatically into every new VM you provision when your Linux user is created. See Setting up your User Settings for more information.
