Motivation & Background

At present, the service update directly stops all, and then starts all, which is not very elegant. It is proposed to support grayscale offline mechanism based on eureka

Basic concept

Expect to achieve goals

• The old service is offline in grayscale, and the new service is launched in grayscale, which does not affect the use of users

Implementation plan

• The service adds offline interface to eureka
• Each service supports multi-port/port range selection, and supports single-machine service multi-instance survival issue link: https://github.com/apache/incubator-linkis/issues/2190
• entrance adds status monitoring

Things to Consider & Note:

• Permission problem of offline interface
• entrance status problem

Changes

Compatibility, Deprecation, and Migration Plan

• What impact (if any) will there be on existing users?
• If we are changing behavior, how will we phase out the older behavior?
• If we require special migration tools, describe them here.
• When will we remove the existing behavior?
