Docker -compose部署失败

[hehe9011]

系统是ubuntu20.04，访问9021端口显示拒绝访问

version: '3.1'
services:
read_all:
image: hectorqin/reader
container_name: reader
restart: always
ports:

volumes:

environment:

需要确认 容器是否正常运行

容器一直在重启，docker logs -f看不到日志，只有大大的reader...

[hectorqin]

volumes:

• ./logs:/logs

磁盘映射改一下，然后再重启，再在logs目录找一下日志文件看看

[hectorqin]

你的docker版本多少？是什么架构的？

加tg群问问群友吧，或者换个镜像试试，这个问题我这边没法复现

[qiebu3509]

（删容器，重新部署，然后机子reboot就好了，但如果之后机子要是reboot之后就又回到这个问题，所以就要重新弄一遍。）
我是试了很多次，感觉这是一个bug

[hectorqin]

启动的时候netty框架检查可用的cpu核心，结果cpu核心为0，不知道这是docker的问题，还是java的问题

这个问题我大前天遇到的。重新部署然后机器reboot就可以了，但之后机器reboot的话又会变回这样，这就很神奇

[hehe9011]

我的已经好了，应该是之前的镜像有问题，更新某一版本就好了

version: '3.1'
services:
read_own:
image: hectorqin/reader
container_name: reader
restart: always
ports:
- 9030:8080
volumes:
- ./logs:/logs
- ./storage:/storage
environment:
- SPRING_PROFILES_ACTIVE=prod

[hehe9011]

果然重启之后又不行了

[lialosiu]

我这也是这种情况，我是在lxc下的alpine模板部署的docker

[hehe9011]

我怀疑是lxc的问题，我是lxc的ubuntu，部署在甲骨文的没问题

[lialosiu]

我找到解决方案了，看这里: itzg/docker-minecraft-server#466 (comment)

[lialosiu]

应该就是在lxc中，jvm不知为啥拿不到cpu核心数
手动
-XX:ActiveProcessorCount=1
指定核心数就好了

[lialosiu]

实测，在docker-compose.yml的相应容器中添加

command: "java -XX:ActiveProcessorCount=1 -jar /app/bin/reader.jar"

springboot就正常跑起来了
