Docker：无法访问容器主机/端口
我有一个容器
ps -a de3ff650fbef tasklist-img "/bin/sh -c 'java -ja" 2 minutes ago Up 2 minutes 8080/tcp, 0.0.0.0:8080->8081/tcp tasklist-img-01 而不能访问像本地主机：8080 /任务列表
当我检查我得到的IP地址172.17.0.2 JSON，也是无法访问

我的docker机运行在IP 192.168.99.100我运行容器与命令
docker run -d -p 8080:8081 --name tasklist-img-01 tasklist-img
我可以访问http://192.168.99.100:8080/ ，它是只返回dropwizard指标， http://192.168.99.100:8080/ task-list/无法访问
我也login

所以我不明白我的微服务在哪里:)））
看起来像是将容器的端口8081映射到主机的8080
docker run -d -p 8080:8081
有8080和8081端口

你可以访问它，当然，但这不是容器的真实8080 。 您可能需要发布端口的范围
docker run -d -p 8080-8081:8080-8081
