Configuring Docker container fixed IP using pipework

First, let's talk about Docker's network mode:

When we use Docker run to create a container, we can use the--net option to specify the network mode of the container, with Docker having a total of 4 network modes:

1:bridge mode,--net=bridge (default).

This is the default setting for the Dokcer network. After installing Docker, the system automatically adds a bridge Docker0 for Docker to use, and when we create a new container, the container obtains an IP address of the same network segment as the DOCKER0 through DHCP. and is connected to the Docker0 bridge by default to realize the network interoperability between the container and host. As follows:

2:host mode,--net=host.

The container created in this mode will not have its own independent network Namespace, that is, there is no independent networking environment. It uses the host's IP and port.

3:container mode,--net=container:name_or_id.

This pattern is to specify an existing container to share the IP and port of the container. In addition to the network of two containers shared, other such as file system, process, etc. or isolated.

4:none mode,--net=none.

In this mode, Dokcer does not make any network configuration for the container. We need to add the network card for the container, configure the IP.

Therefore, if you want to use pipework to configure the IP address of the Docker container, you must be in the None mode.

Pipework Installation:

# wget https://github.com/jpetazzo/pipework/archive/master.zip# Unzip pipework-master.zip# CP pipework-master/ pipework/usr/local/bin/# chmod +x/usr/local/bin/pipework

Create a container for the none mode, assigning IP to it.

#docker run-idt--name test--net=none resin#pipework DOCKER0 test 172.17.0.100/[email protected]

The above operation assigns a 172.17.0.100 IP address to the new test container.
