# Port bindings
|
|
Port bindings is done in two parts. Firstly, by providing a list of ports to
|
|
open inside the container in the `Client().create_container()` method.
|
|
Bindings are declared in the `host_config` parameter.
|
|
|
|
```python
|
|
container_id = cli.create_container(
|
|
'busybox', 'ls', ports=[1111, 2222],
|
|
host_config=cli.create_host_config(port_bindings={
|
|
1111: 4567,
|
|
2222: None
|
|
})
|
|
)
|
|
```
|
|
|
|
|
|
You can limit the host address on which the port will be exposed like such:
|
|
|
|
```python
|
|
cli.create_host_config(port_bindings={1111: ('127.0.0.1', 4567)})
|
|
```
|
|
|
|
Or without host port assignment:
|
|
|
|
```python
|
|
cli.create_host_config(port_bindings={1111: ('127.0.0.1',)})
|
|
```
|
|
|
|
If you wish to use UDP instead of TCP (default), you need to declare ports
|
|
as such in both the config and host config:
|
|
|
|
```python
|
|
container_id = cli.create_container(
|
|
'busybox', 'ls', ports=[(1111, 'udp'), 2222],
|
|
host_config=cli.create_host_config(port_bindings={
|
|
'1111/udp': 4567, 2222: None
|
|
})
|
|
)
|
|
```
|
|
|
|
To bind multiple host ports to a single container port, use the following syntax:
|
|
|
|
```python
|
|
cli.create_host_config(port_bindings={
|
|
1111: [1234, 4567]
|
|
})
|
|
```
|
|
|
|
You can also bind multiple IPs to a single container port:
|
|
|
|
```python
|
|
cli.create_host_config(port_bindings={
|
|
1111: [
|
|
('192.168.0.100', 1234),
|
|
('192.168.0.101', 1234)
|
|
]
|
|
})
|
|
```
