Docker Provider
editDocker Provider
editProvides inventory information from Docker. The available dynamic variables are:
Key | Type | Description |
---|---|---|
|
|
ID of the container |
|
|
Name of the container |
|
|
Image of the container |
|
|
Labels of the container |
To set the container ID dynamically in the configuration, use a variable in the Elastic Agent policy to return container ID information from the provider:
inputs: - id: 'docker-container-logs-${docker.container.id}' type: filestream paths: - '/var/lib/docker/containers/${docker.container.id}/*-json.log'
Sample of the policy generated by this configuration will look like:
inputs: - id: docker-container-logs-b9b898d9c2a1126384d38e9f857b3985480cd05c8e74ffc8b628d92245f5a103 streams: paths: - /var/lib/docker/containers/b9b898d9c2a1126384d38e9f857b3985480cd05c8e74ffc8b628d92245f5a103/*-json.log processors: - add_fields: fields: id: b9b898d9c2a1126384d38e9f857b3985480cd05c8e74ffc8b628d92245f5a103 image: image-name:latest labels: key: value name: container-name target: container - id: docker-container-596bbd114498253985e6a5c4f0f7bf2d9eb8fcd4fe3e6cb53bdfba0cdc7036c8 type: filestream streams: paths: - /var/lib/docker/containers/596bbd114498253985e6a5c4f0f7bf2d9eb8fcd4fe3e6cb53bdfba0cdc7036c8/*-json.log processors: - add_fields: fields: id: 596bbd114498253985e6a5c4f0f7bf2d9eb8fcd4fe3e6cb53bdfba0cdc7036c8 image: other-image-name:latest labels: key: value name: other-container-name target: container
Docker provider ensures that each docker container event is enriched with the container’s metadata, and hence the inputs will be populated with the
add_fields
processor which will be responsible for adding the proper container’s metadata.
