This article will explain in detail how to carry out continuous integration based on jenkins+kubernets+docker. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

To achieve the effect of the project, developers upload the code in gitlab, deploy it with one click, and update the code uniformly for all web containers.

Number of servers: two jenkins are available and eighteen servers are web servers for docker containers.

Architecture operation idea: after the code is updated on gitlab, a change on gitlab is detected through webhook, and then a return receipt will be sent to the local jenkins to execute the task. The task is to pull the code to the local machine, then transfer the code to the local nfs directory through script commands, and then mount it to the host machine of all web containers through the nfs on jenkins. The one-click automatic deployment environment is realized by mapping the mount directory of the host to the root directory of the web page in the container.

Architecture lifetime: jenkins does high availability to achieve uninterrupted work, and docker uses scripts to create the effect of container self-booting.

Architecture diagram:

Order: → gitlab → jenkins → registry kubernetes → docker

Idea: after the developer uploads the code to the gitlab managed code, jenkins automatically pull down and upload it to the registry private warehouse as an image. At the same time, send instructions to kubernetes to close the old container, and then re-enable the new docker image and make it a container to provide services. On how to share the achievements of jenkins+kubernets+docker-based continuous set here, I hope the above content can be of some help to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
