DevOps means no ops!Just to engage in the network, you may be very good, and get a good salary, however, 5 years after the ~, when a person through a simple study can be a web interface or a dedicated tool can be a complex network, so while doing well in the network, in the familiar development, This can alleviate a lot of simple repetitive operation (from the last IDC core cut to see that the configuration is all manual brush!) )。 But the premise is
type-to-subtype relationship between classesCharacteristics:(1) In inheritance, the construction of a base class is not automatically called, it needs to be called specifically in the construction of its derived class.(2) when calling a method of a base class, you need to prefix the class name of the base class with the Self argument variable, except that you do not need to take the self argument when calling a normal function in a class(3) Python always looks for a method of the corresponding

With the system growing, developers, sites, servers more and more, micro-service propulsion, ... And so on, it's increasingly necessary to automate devops.The real reason, of course, is that these problems were foreseen at the start of the team, so it's up to you to automate from the beginning.The tangible benefits are also obvious, savings in human costs, standardized processes, traceable release histories, free hands (repetitive labor), avoidance of errors caused by human actions, an
