## Introduction
|
|
|
|
By default, k3d creates a new (docker) network for every new cluster.
|
|
Using the `--network STRING` flag upon creation to connect to an existing network.
|
|
Existing networks won't be managed by k3d together with the cluster lifecycle.
|
|
|
|
## Connecting to docker "internal"/pre-defined networks
|
|
|
|
### `host` network
|
|
|
|
When using the `--network` flag to connect to the host network (i.e. `k3d cluster create --network host`), you won't be able to create more than **one server node**.
|
|
An edge case would be one server node (with agent disabled) and one agent node.
|
|
|
|
### `bridge` network
|
|
|
|
By default, every network that k3d creates is working in `bridge` mode.
|
|
But when you try to use `--network bridge` to connect to docker's internal `bridge` network, you may run into issues with grabbing certificates from the API-Server.
|
|
Single-Node clusters should work though.
|
|
|
|
### `none` "network"
|
|
|
|
Well.. this doesn't really make sense for k3d anyway ¯\\\_(ツ)\_/¯
