This article focuses on "whether the docker container is stateless". Friends who are interested may wish to take a look. The method introduced in this paper is simple, fast and practical. Let the editor take you to learn whether the docker container is stateless or not.

Stateless server program

The most famous is the WEB server. Each HTTP request has nothing to do with the past, just getting the target URI. After getting the target content, the connection is killed without any trace.

Stateful server

Such as MSN, online games and other servers. The server maintains the status information of each connection, and the server can reproduce the context relationship from the locally stored information when it receives the request sent by each connection. In this way, the client can easily use the default information, and the server can easily manage the state.

For example, when a user logs in, the server can obtain his birthday and other previous registration information according to the user name; and in the subsequent processing, the server can easily find the user's history information.

Docker containers can be deployed quickly and utilize system resources effectively. The state of the application is the data that the application components need to complete their work (that is, to perform a task). Software programming architecture patterns, paradigms, and languages fundamentally describe how to manage the behavior (tasks, operations, etc.) and state (data) of an application. Even micro-service applications have states.

In the micro-service architecture, each service can have multiple instances, and each service instance is designed to be stateless. This means that any instance stores data across operations.

Statelessness just means that the service instance cannot obtain data from elsewhere in order to perform a behavior.

At this point, I believe you have a deeper understanding of whether the docker container is stateless or not, so you might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
