| | | |
| | | Disable assignment of IPv6 gateway IP. |
| | | |
| | | `gw4=IP` |
| | | |
| | | `gw6=IP` |
| | | |
| | | Forces assignment of a specified gateway (only if one is not provided by the IPAM module) |
| | | when creating the interface. Useful for [pyipam](https://github.com/jacekkow/docker-plugin-pyipam) |
| | | with `ptp=1` option and `nogw=1`/`nogw4=1`/`nogw6=1` here. |
| | | |
| | | Using these would add routes like: |
| | | ``` |
| | | default via IP dev eth0 |
| | | IP dev eth0 scope link |
| | | ``` |
| | | |
| | | ## Container creation options |
| | | |
| | | To use these options add `--network name=network_name,driver-opt=option=value,driver-opt=option=value` |
| | | to the `docker run` invocation: |
| | | |
| | | ```bash |
| | | docker run -i -t --rm --network name=test,ip=192.168.1.1,driver-opt=gw4=192.168.0.1,driver-opt=gw6=fe80:: alpine |
| | | ``` |
| | | |
| | | Available options: |
| | | |
| | | `gw4=IP` |
| | | |
| | | `gw6=IP` |
| | | |
| | | Overrides network-level gw4/gw6 options. |
| | | |
| | | ## Manual packaging |
| | | |
| | | In order to test this module in development environment, you can build it |
| | |
| | | ip.link('set', index=idx, state='up') |
| | | if 'parent' in network.Options: |
| | | id_parent = ip.link_lookup(ifname=network.Options['parent'])[0] |
| | | print(ip.link("set", index=idx, master=id_parent)) |
| | | ip.link("set", index=idx, master=id_parent) |
| | | endpoint.Interface.Peer = ifname1 |
| | | |
| | | return ifname0, ifname1 |
| | |
| | | 'SrcName': interface, |
| | | 'DstPrefix': 'eth', |
| | | }, |
| | | 'StaticRoutes': [], |
| | | } |
| | | if gw4 is not None: |
| | | result['Gateway'] = gw4.ip.compressed |
| | | if gw6 is not None: |
| | | result['GatewayIPv6'] = gw6.ip.compressed |
| | | gw4 = endpoint.Options.get("gw4", network.Options.get("gw4", None)) |
| | | if gw4 is not None: |
| | | result['StaticRoutes'].append({ |
| | | 'Destination': gw4 + '/32', |
| | | 'RouteType': 1, |
| | | }) |
| | | result['Gateway'] = gw4 |
| | | gw6 = endpoint.Options.get("gw6", network.Options.get("gw6", None)) |
| | | if gw6 is not None: |
| | | result['StaticRoutes'].append({ |
| | | 'Destination': gw6 + '/128', |
| | | 'RouteType': 1, |
| | | }) |
| | | result['GatewayIPv6'] = gw6 |
| | | return result |
