我有一个容器

无法访问localhost:8080 / task-list
当我检查时,我的IP地址为172.17.0.2的json,它也无法访问

我的docker机器在ip 192.168.99.100下运行 我使用命令
运行容器docker run -d -p 8080:8081 --name tasklist-img-01 tasklist-img
我可以访问http://192.168.99.100:8080/,它只返回dropwizard指标,http://192.168.99.100:8080/task-list/无法访问
我也记录了

所以我无法理解我的微服务在哪里?:)))
答案 0 :(得分:2)
看起来您已将容器的端口8081
映射到主机的8080
docker run -d -p 8080:8081
还有端口正在监听8080
和8081
INFO [2016-11-14 19:32:30,486] org.eclipse.jetty.server.ServerConnector: Started application@522a32b1{HTTP/1.1}{0.0.0.0:8080}

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