Demand
In the process of using Docker, we sometimes have the need to configure the Docker container to the same network segment as the host. To achieve this demand, we simply will Docker container and host network card Bridge, and then to
Docker learning: configure the rancher network environment, download and start the Tomcat container1. About rancher
The rancher environment was set up last time, but the network was not configured properly (). Container not created successfully. This time, it turns out to be a network problem. The coreos installed in virtualbox is not configured with an ip addres
Container interconnection between multiple physical hosts of Docker
The default bridge Nic of Docker is docker0. It only bridges all container NICs on the local machine. For example, the virtual Nic of the container is generally called veth * on the host, while
=CONTIANER:NAME_OR_ID: Use a network stack of existing containers to share network resources such as IP addresses and ports of existing containers.
--net=none: Put the new container on the isolated network stack without network configuration, we need to specify the item for the container configuration network.

To add a data volume
You can use the Docker create and Docker run commands in conjunction with-V to add data volumes to the container. You can mount a data volume by using-V multiple times:

mount the host directory as a data volume

Under normal circumstances, if our computer in a networked environment, we can directly through the Docker pull images to obtain the relevant image, of course, this must be a networked environment, depending on the user's network speed or the size of the image has a different wait, If we were able to build a mirror repository like remote networking locally, and put our usual images in our own managed repositories, wouldn't it be possible to qu

Using the Docker process, we need to look at the data generated in the container, and between the container and the container, the container and the host before the data sharing, backup and other operations, where the data management of the

2. With the Dockerfile file, you can create image files based on Dockerfile, and in the directory where Dockerfile is located, run the following command
sudo docker build-t centos6-ssh.
When the command succeeds, an image named Centos6-ssh is created and can be viewed using the sudo docker images.
