How to bring it to production?

Question

Java

The problem is this. There is a test server (with a test DB) on which all improvements are worked out. After that, everything is transferred to production. And it often happens that the production server does not work like the test one and all sorts of bugs appear. Is there any solution to this problem so that the user does not encounter bugs? Thank you!

Answer 1

Docker

Answer 2

Well, they usually make a stage where the base is almost 1 in 1, like on the sale. Everything is tested there and then for sale

Answer 3

There are rules for this - the immutability of artifacts throughout the entire delivery cycle to the sale, as well as the identity of the environment of the stage and prod environments.
