We also need to understand the new abstract definition of service in Docker 1.12. You may notice the Docker Service command in the previous output. The so-called Docker service, refers to running in the container and responsible for the outside world to provide running in the Swarm cluster "service" software fragments.
Such a service can consist of a single or multiple sets of container

But this does not mean that, like other users on the network can get control of the computer, although the hacker exploited the vulnerability does not have control rights, but it is easy to leak computer-related information, so as to facilitate the hacker attack, so the vulnerability is still very dangerous. However, as long as it is a shell loophole, it is very dangerous. Shell as a bridge between human and computer communication, if this layer of bridge problems, the consequences imaginable
Once the Docker container is started, the parameters cannot be changed. The most common change in the production environment is the port mapping, in order to solve this problem, then first of all planning, this article listed two port planning scheme, if the subsequent maintenance in order to increase the port mapping scene, this paper also gives a dynamic port mapping expansion scheme.

I made an image, exposed port 8000, and started the symfony built-in server in the container. The port number is 8000, so there is no problem with internal access, then, port 8001 of the host machine is mapped to port 8000. According to my understanding, it should be okay. I made an image, exposed port 8000, and starte
PHP is a scripting language that requires a PHP interpreter to analyze and run PHP files. When PHP is used as a CGI Service Web request, it needs to be embedded into a Web server. The most common thing is to integrate it into Apache or IIS. That is to say, before using PHP, you need to install Apache or IIS and correctly configure the parameters they integrate with PHP. Although this configuration is already very standard and has rich documentation, we often encounter problems when installing Ap
