Cloudify HA cluster maintenance

Cloudify Cluster status

Adding a new cluster node

When a new cluster node is added, it is required to configure its status reporter by the following steps:

1. Collect the following data:

• A list of the current private IP addresses of the Cloudify managers, There must be at least one address, that list will be updated automatically afterward.
• Run the following command on each of the Cloudify managers to retrieve specific internal communication tokens:

  cfy_manager status-reporter get-tokens
  

  This will return a list of three token named ‘manager_status_reporter’, ‘db_status_reporter’ and ‘broker_status_reporter’, please copy aside ‘db_status_reporter’ and ‘broker_status_reporter’ tokens.

• Please copy to all cluster nodes, expect Cloudify management’s service ones, the CA certificate that was specified in the config.yaml at the section ‘ssl_inputs’ of field ‘ca_cert_path’. This is for for a secure connection between the reporters and Cloudify system.

1. To enable and configure the node’s status reporter, execute (on every node’s machine):

cfy_manager status-reporter configure --token <relevant status reporter token> --ca-path <Cloudify-rest CA certificate local path> --managers-ip <list of current managers ip>

Configuring status reporter

The Status reporter can be configured by running the following command:

cfy_manager status-reporter configure <--reporting-freq/--token/--managers-ip/--log-level>

• Cluster node status reporting frequency of the reporter, the default frequency is once every 5 seconds.
• The HTTP token used by the status reporter to securely communicate with Cloudify management service.
• Cloudify’s management services nodes’ IP addresses, needed for the reporter to send his node status.
• The log level of the status reporter {INFO,WARNING,ERROR,DEBUG}.
