Filters (Swarm)

Swarm filters

Filters tell Docker Swarm scheduler which nodes to use when creating and running a container.

Configure the available filters

Filters are divided into two categories, node filters and container configuration filters. Node filters operate on characteristics of the Docker host or on the configuration of the Docker daemon. Container configuration filters operate on characteristics of containers, or on the availability of images on a host.
