How to install several ssh keys when creating droplet through api

Can you share an example of how you are calling the API and the cloud config script used? It would help narrow down the issue. At the surface, what you’re trying to should be supported.

You have a few options for adding multiple SSH keys to a Droplet:

The API allows for adding more than one SSH key when creating a Droplet. The ssh_keys field and take an array of SSH key IDs. For example, the body of your request might look like:

{
    "name":"example.com",
    "region":"nyc3",
    "size":"s-1vcpu-1gb",
    "image":"ubuntu-16-04-x64",
    "ssh_keys":[123456, 654321]
}

You can also add SSH keys to new Droplets via user data. For example:

#cloud-config
users:
  - name: root
    ssh-authorized-keys:
      - ssh-rsa AAAAB3NzaC1yc2EAAAADA....

If you specify the root user, these keys will be merged with the keys specified via the API into the ~/.ssh/authorized_keys file.

If you are still having issues and want to do further debugging, you can reset the root password for your Droplet via the “Access” tab for the Droplet in the control panel in order to gain access.

Yeah that’s no help at all. Like I said, I’m adding one key for access, and one key to communicate with a third party. Both your options are only for access.

This is my config:

{
  name: 'NAME',
  region: 'lon1',
  size: 's-1vcpu-1gb',
  image: 'ubuntu-16-04-x64',
  backups: false,
  ipv6: true,
  user_data: '#cloud-config
    ssh_keys:
        rsa_private: |
          -----BEGIN RSA PRIVATE KEY-----
          -----END RSA PRIVATE KEY-----

        rsa_public: ssh-rsa AAAAB3NzaC1y
  ',
  ssh_keys: [ 18XXX16 ],
  private_networking: null,
  volumes: null,
  tags: [ 'dev' ] 
}

I naturally removed the keys themselves.

Now what I’m trying to do is: Create a droplet that I can reach via the SSH key supplied in “ssh_keys” and give that droplet access to my github account via the “user_data ssh_keys”.
