# `prefect_docker.host`
Module containing Docker host settings.
## Classes
### `DockerHost`
Block used to manage settings for interacting with a Docker host.
**Attributes:**
* `base_url`: URL to the Docker server, e.g. `unix\:///var/run/docker.sock`
or `tcp\://127.0.0.1\:1234`. If this is not set, the client will
be configured from environment variables.
* `version`: The version of the API to use. Set to auto to
automatically detect the server's version.
* `timeout`: Default timeout for API calls, in seconds.
* `max_pool_size`: The maximum number of connections to save in the pool.
* `client_kwargs`: Additional keyword arguments to pass to
`docker.from_env()` or `DockerClient`.
**Examples:**
Get a Docker Host client.
```python theme={null}
from prefect_docker import DockerHost
docker_host = DockerHost(
base_url="tcp://127.0.0.1:1234",
max_pool_size=4
)
with docker_host.get_client() as client:
... # Use the client for Docker operations
```
**Methods:**
#### `get_client`
```python theme={null}
get_client(self) -> docker.DockerClient
```
