Then, start a simple client container and pass it on to it HOST_IP . We are using the eth0 address, but we can also use the Docker0 IP. We are passing it an environment variable because it is configured to change between two deployments.
$ docker run -e HOST_IP=$(hostname --all-ip-addresses | awk '{print $1}') -i -t ubuntu:14.04 /bin/bash
Before we did the experiment is on a host, in fact, in the real environment there are multiple hosts, containers on these hosts to start, run, stop and destroy, related containers will communicate with each other over the network, whether they are running on the same host.For this kind of song Multi-host environment, how should we manage it efficiently?The first problem is: Install and configure Docker for
In front of our experimental environment there is only one Docker host, and all the containers are running on this host. However, in a real environment there will be multiple hosts, where containers are started, run, stopped, and destroyed, and related containers communicate with each other over the network, regardless of whether they are located in the same host.How do we manage this multi-host environment effectively?The first problem we faced was i
Changes in Docker version:Docker starts with the 1.13.x version, which is divided into Enterprise EE and Community Edition CE, and the version number is also changed to the timeline, for example, 17.03 is March 2017, a bit similar to the version of Ubuntu release method.The Enterprise Edition will naturally provide some additional services, which are certainly fees.

[Docker discussion]docker not everything, and you don't have to deploy everything on Docker.When I read an article "running and upgrading a MySQL server in a docker container": https://intercityup.com/blog/running-upgrading-mysql-server-docker/After that, I don't think Docker
Docker is a very hot technology at the moment, about the introduction of Docker here is not much to say, this article mainly describes how to configure Docker in the Ubuntu 14.04 environment of the local warehouse, for large-scale use of Docker in the LAN, frequently from the official website to download image files, U
ObjectiveIn a previous blog, "Setting up a Docker registry private warehouse in Ubuntu" introduces a simple way to build a Docker private repository. But it was used to modify the "--insecure-registry" parameters, which is used in the local area network, but also reluctantly suitable. But if you want to build a private warehouse server for a production environment, there is a big security risk. So, here is
What is Docker?
Simply put, Docker is a "container" for programs written by the Go language (Linux containers, LXCS); At present, the cornerstone of cloud services is operating system-level isolation, virtual multiple hosts on the same physical server. Docker implements an application-level isolation; It changes our basic development, Operation unit, by direct O

RUN
(Shell mode) RUN echo hello RUN ["executable", "param1", "param2"] (exec mode) RUN ["/bin/bash", "-c ", "echo hellow"] EXPOSE specifies the container running port. It only tells docker that the container uses this port, but does not automatically open the port. Instead, it adds the port ing command to the run.

downloading it? Does the image of Linux run in Windows Server Docker?
Answer: Windows Docker and Linux are incompatible. You cannot run Linux image on Windows. Because Docker is a shared kernel, the two implementations are completely different.
Q: Does the GUI support?
A: You can support the GUI, just like Linux Docker
Preface
When you have more than one physical machine, consider using cluster mode, so how does Docker use the cluster for management? The main use of this is the Docker swarm mode, which is the management and orchestration of the Docker cluster. The so-called orchestration refers to the management of multiple clusters, host configuration, container scheduling and

Basic Introduction and example of Docker
Docker has developed over the past few years. Particularly since the 2013 s, with the open source of an LXC-based advanced container engine, Docker has been well supported in both linux and windows, in addition, many companies have used docker in the actual production environmen
