Host-Deployment Process

When an agentless host is added to the managed environment, Key Manager performs the following jobs on the host:

  1. Key Manager creates a discovery parent job.

  2. Key Manager creates a child job called discover-host. This job scans the added host for basic software information, such as its OS version. Key Manager checks the host for an existing unique ID file, and creates one if none are found. The host is recorded to Key Manager, with the host state set to available.

  3. Once the discover-host job finishes, Key Manager creates a child job called to-monitored-statehost. If password authentication is used for the management account, this job adds an agentless management key, used for subsequent management connections. Key Manager then attempts to open a management connection with the newly established key. If the connection succeeds, the host is brought to the monitored state.

  4. Key Manager initiates a scan-full job on the host, during which Key Manager discovers information about the host, such as its present SSH software, users, and user keys.

  5. If scheduled key-activity scans are enabled, Key Manager performs a key-activity scan job scan-hostkey-activity on the host. The initial key-activity scan detects and updates key-usage statistics to Key Manager.

When a agent-based host is added to the managed environment, Key Manager performs the following jobs on the host:

  1. Key Manager creates a job called discover-agent-host. This job scans the added host for basic software information, such as the OS version. Key Manager checks the host for an existing unique ID file, and creates one if necessary. Additionally, this job creates and deploys the Key Manager agent configuration on the host. The host is added to Key Manager with its state set to monitored.

  2. Key Manager initiates a scan-full job on the host. During this initial host scan, Key Manager gathers information about the host, such as its present SSH software, users, and user keys.
