# Client API
|
||
|
||
To instantiate a `Client` class that will allow you to communicate with a
|
||
Docker daemon, simply do:
|
||
|
||
```python
|
||
>>> from docker import Client
|
||
>>> cli = Client(base_url='unix://var/run/docker.sock')
|
||
```
|
||
|
||
**Params**:
|
||
|
||
* base_url (str): Refers to the protocol+hostname+port where the Docker server
|
||
is hosted.
|
||
* version (str): The version of the API the client will use. Specify `'auto'`
|
||
to use the API version provided by the server.
|
||
* timeout (int): The HTTP request timeout, in seconds.
|
||
* tls (bool or [TLSConfig](tls.md#TLSConfig)): Equivalent CLI options: `docker --tls ...`
|
||
* user_agent (str): Set a custom user agent for requests to the server.
|
||
|
||
|
||
****
|
||
|
||
## attach
|
||
|
||
The `.logs()` function is a wrapper around this method, which you can use
|
||
instead if you want to fetch/stream container output without first retrieving
|
||
the entire backlog.
|
||
|
||
**Params**:
|
||
|
||
* container (str): The container to attach to
|
||
* stdout (bool): Get STDOUT
|
||
* stderr (bool): Get STDERR
|
||
* stream (bool): Return an iterator
|
||
* logs (bool): Get all previous output
|
||
|
||
**Returns** (generator or str): The logs or output for the image
|
||
|
||
## build
|
||
|
||
Similar to the `docker build` command. Either `path` or `fileobj` needs to be
|
||
set. `path` can be a local path (to a directory containing a Dockerfile) or a
|
||
remote URL. `fileobj` must be a readable file-like object to a Dockerfile.
|
||
|
||
If you have a tar file for the Docker build context (including a Dockerfile)
|
||
already, pass a readable file-like object to `fileobj` and also pass
|
||
`custom_context=True`. If the stream is compressed also, set `encoding` to the
|
||
correct value (e.g `gzip`).
|
||
|
||
**Params**:
|
||
|
||
* path (str): Path to the directory containing the Dockerfile
|
||
* tag (str): A tag to add to the final image
|
||
* quiet (bool): Whether to return the status
|
||
* fileobj: A file object to use as the Dockerfile. (Or a file-like object)
|
||
* nocache (bool): Don't use the cache when set to `True`
|
||
* rm (bool): Remove intermediate containers. The `docker build` command now
|
||
defaults to ``--rm=true``, but we have kept the old default of `False`
|
||
to preserve backward compatibility
|
||
* stream (bool): *Deprecated for API version > 1.8 (always True)*.
|
||
Return a blocking generator you can iterate over to retrieve build output as
|
||
it happens
|
||
* timeout (int): HTTP timeout
|
||
* custom_context (bool): Optional if using `fileobj`
|
||
* encoding (str): The encoding for a stream. Set to `gzip` for compressing
|
||
* pull (bool): Downloads any updates to the FROM image in Dockerfiles
|
||
* forcerm (bool): Always remove intermediate containers, even after unsuccessful builds
|
||
* dockerfile (str): path within the build context to the Dockerfile
|
||
* buildargs (dict): A dictionary of build arguments
|
||
* container_limits (dict): A dictionary of limits applied to each container
|
||
created by the build process. Valid keys:
|
||
- memory (int): set memory limit for build
|
||
- memswap (int): Total memory (memory + swap), -1 to disable swap
|
||
- cpushares (int): CPU shares (relative weight)
|
||
- cpusetcpus (str): CPUs in which to allow execution, e.g., `"0-3"`, `"0,1"`
|
||
* decode (bool): If set to `True`, the returned stream will be decoded into
|
||
dicts on the fly. Default `False`.
|
||
* shmsize (int): Size of /dev/shm in bytes. The size must be greater
|
||
than 0. If omitted the system uses 64MB.
|
||
* labels (dict): A dictionary of labels to set on the image
|
||
|
||
**Returns** (generator): A generator for the build output
|
||
|
||
```python
|
||
>>> from io import BytesIO
|
||
>>> from docker import Client
|
||
>>> dockerfile = '''
|
||
... # Shared Volume
|
||
... FROM busybox:buildroot-2014.02

||
'{"stream":"Removing intermediate container dba30f2a1a7e\\n"}',

|
||
an open file handle as 'src', in which case the data will be read from that
|
||
file.

If `src` is unset but `image` is set, the `image` parameter will be taken as
|
||
the name of an existing image to import from.

## Version mismatch
|
||
|
||
You may encounter an error like this:
|
||
|
||
```text
|
||
client is newer than server (client API version: 1.24, server API version: 1.23)
|
||
```
|
||
|
||
To fix this, you have to either supply the exact version your server supports
|
||
when instantiating the `Client`:
|
||
|
||
```python
|
||
client = docker.Client(version="1.23")
|
||
```
|
||
|
||
or let the client automatically detect the newest version server supports:
|
||
|
||
```python
|
||
client = docker.Client(version="auto")
|
||
```
