ReplicaSet

POST Run a container via replicaSet

POST /api/v1/replicaSet

Run a container consists of two parts: create and start.

When the container is created, the creation information is saved to etcd.

ReplicaSet is just an abstract concept, there is no concrete implementations,it just has to manage docker container, and save the container historical version information, that's all.

Body Parameters

PATCH Patch a container via replicaSet

PATCH /api/v1/replicaSet/{name}

Patch the configuration of the latest version of existing container via create a new container and copy the old container system data to the new container.
