# Use a custom Docker host
|
|
|
|
If you are interfacing with Docker via TCP, set `DOCKER_HOST` to the correct URL.
|
|
|
|
```ini
|
|
DOCKER_HOST=tcp://docker_socket_proxy:2375
|
|
```
|
|
|
|
If you do this as you seek to restrict access to the Docker socket, this tool is potentially calling the following Docker APIs:
|
|
|
|
| API | When |
|
|
|-|-|
|
|
| `Info` | always |
|
|
| `ContainerExecCreate` | running commands from `exec-labels` |
|
|
| `ContainerExecAttach` | running commands from `exec-labels` |
|
|
| `ContainerExecInspect` | running commands from `exec-labels` |
|
|
| `ContainerList` | always |
|
|
`ServiceList` | Docker engine is running in Swarm mode |
|
|
| `ServiceInspect` | Docker engine is running in Swarm mode |
|
|
| `ServiceUpdate` | Docker engine is running in Swarm mode and `stop-during-backup` is used |
|
|
| `ConatinerStop` | `stop-during-backup` labels are applied to containers |
|
|
| `ContainerStart` | `stop-during-backup` labels are applied to container |
|
|
|

|
|
In case you are using [`docker-socket-proxy`][proxy], this means following permissions are required:
|
|
|
|
| Permission | When |
|
|
|-|-|
|
|
| INFO | always required |
|
|
| CONTAINERS | always required |
|
|
| POST | required when using `stop-during-backup` or `exec` labels |
|
|
| EXEC | required when using `exec`-labeled commands |
|
|
| SERVICES | required when Docker Engine is running in Swarm mode |
|
|
| NODES | required when labeling services `stop-during-backup` |
|
|
| TASKS | required when labeling services `stop-during-backup` |
