PrerequisitesΒΆ

Prior to generating the user data for cloud-init, complete the following steps:

  1. Verify that your Decapod installation is up and running.

  2. Obtain the server discovery token. Decapod uses automatic server discovery and cloud-init is required only for that. To access the Decapod API, servers will access it using an authentication token with limited capabilities (posting to the server discovery API endpoint). The server discovery token is set in the api.server_discovery_token section of the config.yaml file. Keep this token private. To obtain the token:

    $ grep server_discovery_token config.yaml
  server_discovery_token: "7f080dab-d803-4339-9c69-e647f7d6e200"

  3. Generate an SSH public key. To generate the SSH public key from a private one, run:

    $ ssh-keygen -y -f ansible_ssh_keyfile.pem > ansible_ssh_keyfile.pem.pub

    Note

    The ansible_ssh_keyfile.pem file should have the 0600 permissions:

    $ chmod 0600 ansible_ssh_keyfile.pem
