Docker Engine API
The Engine API is an HTTP API served by Docker Engine. It is the API the Docker client uses to communicate with the Engine, so everything the Docker client can do can be done with the API. Most of the client's commands map directly to API endpoints (e.g. `docker ps` is `GET /containers/json`). The notable exception is running containers, which consists of several API calls. # Errors The API uses standard HTTP status codes to indicate the success or failure of the API call. The body of the response will be JSON in the following format: ``` { "message": "page not found" } ``` # Versioning The API is usually changed in each release of Docker, so API calls are versioned to ensure that clients don't break. For Docker Engine 17.09, the API version is 1.32. To lock to this version, you prefix the URL with `/v1.32`. For example, calling `/info` is the same as calling `/v1.32/info`. Engine releases in the near future should support this version of the API, so your client will continue to work even if it is talking to a newer Engine. In previous versions of Docker, it was possible to access the API without providing a version. This behaviour is now deprecated will be removed in a future vers
