Entities

entity std::AgentConfig

Parents: std::PurgeableResource

Control agent settings. Currently these settings are only applied to autostarted agents

attribute bool? autostart

When this flag is set to true, the resource will be exported and set the agent map on the orchestrator. When false (or not set), this instance is ignore but can be used to generate agent configuration files.

attribute std::config_agent agentname

The name of the agent to which this config applies.

attribute string agent='internal'

If a resource is exported, agent manages the resource.

attribute string uri='local:'

The uri that indicates how the agent should execute. Currently the following uri are supported: * “” An empty string. This is the same as running it locally * local: Manage resource locally * ssh://[user@]hostname[:port] Login using ssh. When user is left out, root is assumed. For port, the system default is used. * host The actual hostname or ip to use. Altough this is not a valid host in uri form it is supported. * A query string can be used to set the properties: * python: The python interpreter to use. The default value is python * retries: The number of retries before giving up. The default number of retries 10 * retry_wait: The time to wait between retries for the remote target to become available. The default wait is 30s. Example: ssh://centos@centos-machine/?python=python3 (This would connect to a the centos machine and use python3 as it’s interpreter)
