Dokcer function Nacos Container auto exit problem

Refer to the post

The student party , Rented ECS ,2 nucleus 2G. Use Docker function Nacos The container always exits automatically when it is found .Nacos There is no obvious error message in the log . Check the memory overflow error , The instructions are as follows

journalctl -k | grep -i -e memory -e oom

It happened. OOM error , Automatically killed the related process

Look again Nacos journal , As shown in the figure below , It is found that the heap memory is set too large , Initial heap memory Xms Set up 1G, Maximum heap memory Xmx Set up 1G, The younger generation Xmn Set up 512M.

Problem found , take JVM The heap memory setting is small

I use it docker-compose function Nacos Of related services .Nacos The relevant part Of yml The code is as follows

version: "3.2"

services:
  nacos:
    image: nacos/nacos-server
    environment:
      - MODE=standalone
      - JVM\_XMS=64m
      - JVM\_XMX=64m
      - JVM\_XMN=16m
    ports:
      - "8848:8848"

Remember to look again after starting Nacos Is the log based on the memory you configure , If it doesn't change , It should be yml The format inside is wrong , Then check whether the configuration file you wrote is correct . After rerunning the configuration file , We see the Nacos journal , The configuration is found to be effective

Check the running Docker Containers

docker ps

No automatic exit . But there are new problems .nacos Although it won't quit automatically , But the log also reported that the heap memory overflowed , I forgot to cut the wrong picture , As we all know java Heap memory overflow is enough

Check it out nacos Using memory , Use instruction

ps -aux|grep nacos

It is found that it occupies about 300 many M Physical memory . Then readjust the heap memory in the previous way .
