docker microservices

"Problem description"One of the most serious resource problems in using Spring cloud is the high memory footprint, and the fact that there is not a large amount of development testing, or even a problem with the service not being properly accessed."Cause analysis"The main reason is that when a single micro-service from spring Cloud is deployed on a Linux system server, the memory consumed on a Linux system computer with 8G of memory reaches around 1G. With only 5 or so micro services deployed, t
