using pipework to configure the Docker container to the local network environment 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

It is important to note that the image files downloaded from the Docker pool are identical to the official image files.After installing Docker, you can use the official registry image to build a set of local private warehouse environments: Docker run –d –p : Registry After the input can wait, in fact, the local repository itself is a contai

ObjectiveIn Docker engine v1.12, using swarm can easily create a overlay mode network, but it can only be used by the service below Swarm, which is completely isolated relative to container. In v1.13, when running containers, you can join the overlay network that was previously customized in swarm mode!1. Create swarm in one Docker host (172.100.1.17)$

command is bash, attach is also connected to bash so that the container can be manipulated at will. Closing a connection is easy to think of, is to exit Bash:exit. But, however, this exit can cause a problem when the container stops because the 1th process exit (the Attach command Connection bash) will assume that the task is complete. As above, the container has been stopped (exited). Therefore, I recommend using the EXEC command to manipulate

This article describes the configuration of simple load balancing on the Docker, host for the Ubuntu 14.04.2 LTS, two CentOS containers, host installation Nginx, two containers installed TOMCAT7. The structure is as follows: The rationale for this scenario is to map the port of the host and the port of the Docker container (that is, a port accessing the host will map to the port of the

Macvlan network driver after version 1.12, so that we can more easily configure the bridging network for the container.MacvlanAs the name implies, the principle of Macvlan is to virtual on the host physical network card, multiple sub-network card, through the different MAC address in the Data link layer (the database link) for network data forwarding, it is relatively new network virtualization technology, need more new kernel support (Linux kernel v3.9–3.19 and 4.0+).

Docker creates mirrors based on containers that already have mirrors* Docker run Centos/bin/bash first causes the mirror to open the container.* Docker start DE8 launches the specified mirror container. De8 is the ID of the image and can be shortened to 3 bits.* After running Docker exec-it De8/bin/bash, enter into the

How do I get to the container after the Docker container is running? At first I was using SSH. If you only start a container and use SSH to handle it, you only need to map the container's 22 port to one of the local ports. When I started the five containers, each container by default is not configured SSH server, installation configuration sshd, map container ssh port, it is really troublesome.I find that m

Unlike bash, which has a PID of 1, we are currently connected to the 24 bash, which can execute commands and operate at will. And after exiting, it does not affect the 1 PID of Bash, so that the container can continue to run.Visible, after I quit the container bash, the container is still running. After I use EXEC to execute the PS command o
