## dockerswarm_sd_configs
|
||||
|
||||
Docker Swarm SD configurations allow retrieving scrape targets from [Docker Swarm engine](https://docs.docker.com/engine/swarm/).
|
||||
|
||||
One of the following roles can be configured to discover targets:
|
||||
|
||||
* `role: services`
|
||||
|
||||
The `services` role discovers all Swarm services and exposes their ports as targets.
|
||||
For each published port of a service, a single target is generated. If a service has no published ports,
|
||||
a target per service is created using the port parameter defined in the SD configuration.
|
||||
|
||||
Available meta labels for `role: services`:
|
||||
|
||||
* `__meta_dockerswarm_service_id`: the id of the service
|
||||
* `__meta_dockerswarm_service_name`: the name of the service
|
||||
* `__meta_dockerswarm_service_mode`: the mode of the service
|
||||
* `__meta_dockerswarm_service_endpoint_port_name`: the name of the endpoint port, if available
|
||||
* `__meta_dockerswarm_service_endpoint_port_publish_mode`: the publish mode of the endpoint port
|
||||
* `__meta_dockerswarm_service_label_<labelname>`: each label of the service
|
||||
* `__meta_dockerswarm_service_task_container_hostname`: the container hostname of the target, if available
|
||||
* `__meta_dockerswarm_service_task_container_image`: the container image of the target
|
||||
* `__meta_dockerswarm_service_updating_status`: the status of the service, if available
|
||||
* `__meta_dockerswarm_network_id`: the ID of the network
|
||||
* `__meta_dockerswarm_network_name`: the name of the network
|
||||
* `__meta_dockerswarm_network_ingress`: whether the network is ingress
|
||||
* `__meta_dockerswarm_network_internal`: whether the network is internal
|
||||
* `__meta_dockerswarm_network_label_<labelname>`: each label of the network
|
||||
* `__meta_dockerswarm_network_scope`: the scope of the network
|
||||
|
||||
* `role: tasks`
|
||||
|
||||
The `tasks` role discovers all Swarm tasks and exposes their ports as targets.
|
||||
For each published port of a task, a single target is generated. If a task has no published ports,
|
||||
a target per task is created using the port parameter defined in the SD configuration.
|
||||
|
||||
Available meta labels for `role: tasks`:
|
||||
|
||||
* `__meta_dockerswarm_container_label_<labelname>`: each label of the container
|
||||
* `__meta_dockerswarm_task_id`: the id of the task
|
||||
* `__meta_dockerswarm_task_container_id`: the container id of the task
|
||||
* `__meta_dockerswarm_task_desired_state`: the desired state of the task
|
||||
* `__meta_dockerswarm_task_slot`: the slot of the task
|
||||
* `__meta_dockerswarm_task_state`: the state of the task
|
||||
* `__meta_dockerswarm_task_port_publish_mode`: the publish mode of the task port
|
||||
* `__meta_dockerswarm_service_id`: the id of the service
|
||||
* `__meta_dockerswarm_service_name`: the name of the service
|
||||
* `__meta_dockerswarm_service_mode`: the mode of the service
|
||||
* `__meta_dockerswarm_service_label_<labelname>`: each label of the service
|
||||
* `__meta_dockerswarm_network_id`: the ID of the network
|
||||
* `__meta_dockerswarm_network_name`: the name of the network
|
||||
* `__meta_dockerswarm_network_ingress`: whether the network is ingress
|
||||
* `__meta_dockerswarm_network_internal`: whether the network is internal
|
||||
* `__meta_dockerswarm_network_label_<labelname>`: each label of the network
|
||||
* `__meta_dockerswarm_network_label`: each label of the network
|
||||
* `__meta_dockerswarm_network_scope`: the scope of the network
|
||||
* `__meta_dockerswarm_node_id`: the ID of the node
|
||||
* `__meta_dockerswarm_node_hostname`: the hostname of the node
|
||||
* `__meta_dockerswarm_node_address`: the address of the node
|
||||
* `__meta_dockerswarm_node_availability`: the availability of the node
|
||||
* `__meta_dockerswarm_node_label_<labelname>`: each label of the node
|
||||
* `__meta_dockerswarm_node_platform_architecture`: the architecture of the node
|
||||
* `__meta_dockerswarm_node_platform_os`: the operating system of the node
|
||||
* `__meta_dockerswarm_node_role`: the role of the node
|
||||
* `__meta_dockerswarm_node_status`: the status of the node
|
||||
|
||||
The `__meta_dockerswarm_network_*` meta labels are not populated for ports which are published with `mode=host`.
|
||||
|
||||
* `role: nodes`
|
||||
|
||||
The `nodes` role is used to discover Swarm nodes.
|
||||
|
||||
Available meta labels for `role: nodes`:
|
||||
|
||||
* `__meta_dockerswarm_node_address`: the address of the node
|
||||
* `__meta_dockerswarm_node_availability`: the availability of the node
|
||||
* `__meta_dockerswarm_node_engine_version`: the version of the node engine
|
||||
* `__meta_dockerswarm_node_hostname`: the hostname of the node
