Course Introduction：In Go, structures cannot be directly declared as generic types, but similar behavior can be achieved through methods or functions using generic parameters. 1. Generic parameters can be used in the structure method, so that the method can process multiple types of data but does not save generic data inside the structure; 2. The structure field can use any or custom interface to save different types of data, but it will lose the compilation time type checking and need to be used with caution; 3. Encapsulating generic logic into independent functions can keep the structure simple and clear, suitable for generic operations that are multiple times. These three methods can be selected and used according to actual needs.

Course Introduction：dockerrun is used to create and start a new container, while dockerstart is used to restart existing containers. The specific differences include: 1.dockerrun=Create Start, a new container will be generated every time you run; 2.dockerstart=Only start, it must be used on the created container; 3. Configurations such as port mapping and volume can only be set during dockerrun, and can not be changed afterwards; 4. If you want multiple instances, use dockerrun multiple times, and if you want to restart the same instance, use dockerstart. Therefore, dockerrun is equivalent to "create and start", while dockerstart is "start again".

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
