Entities

entity std::AgentConfig

Parents: std::PurgeableResource

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

attribute bool autostart=false

When this flag is set to true, the resource will be exported and set the agent map on the orchestrator. When false, this instance is ignored 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. Although 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)

The following implements statements select implementations for this entity:

A base entity for resources that can be exported. This type add specific attributes that are common for most handlers. It is not required to inherit from this entity at the moment but highly recommended for documentation purposes.

attribute bool send_event=false

This controls whether a resource should send its deploy state to the resources in its provides.

attribute bool receive_events=true

This controls whether a resource should receive events from other resources, i.e. its requires that have send_event=true. Resources with receive_events=true will always be deployed whenever a dependency produces an event. Set this to false for resources that do not rely on events (most practical resources) to reduce the amount of redundant deploys, thereby increasing performance (will not have any effect for inmanta-core<14).
