I the most simple question is our development and production environment are commonly isolated, if I were in the development environment test good, how to deploy to production environment? A new application through a mirror copy must be easy to deploy, is I make a copy of the virtual machine directly, but the inside of the configuration is not same to revise? Such as IP address, configuration file, after all, two environment of the network is not the same, and database maintenance, an application has been upgraded, there are changes in production environment database, there are production data, data is not the same test environment, table structure is modified, how to deploy to a production environment without affecting the existing data?

CodePudding user response:

Is to run certain programs, or the environment, (docker)

Separate databases, or another set of IP storage. (fixed)

CodePudding user response:

Environment must include the information such as the server's IP ah, not only the logic code, two different network environment how can simply copy?
