Kurento Docker: 无法连接到 127.0.0.1 端口 8888: 连接被拒绝

Question

刚在里面做了 docker build -t kurento-media-server .：https://github.com/Kurento/kurento-docker/tree/master/kurento-media-server。

一切都已建成。我运行 docker run -p 8888:8888 kurento-media-server 然后 curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: 127.0.0.1:8888" -H "Origin: 127.0.0.1" http://127.0.0.1:8888/kurento。它错误的说它无法连接到端口。

容器的输出如下：

+ set -e
+ '[' -n '' ']'
+ '[' -n '' -a -n '' ']'
+ sed /::1/d
+ cat /etc/hosts
+ tee /etc/hosts
+ exec /usr/bin/kurento-media-server

Answer 1

有时我忘记 Linux 指令不等于 Docker 运行 Mac 指令。

curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: 172.16.88.128:8888" -H "Origin: 127.0.0.1" http://172.16.88.128:8888/kurento 是正确的命令，其中 non-localhost IP 是我从 docker-machine ip default

获得的

Kurento Docker: 无法连接到 127.0.0.1 端口 8888: 连接被拒绝

Kurento Docker: Failed to connect to 127.0.0.1 port 8888: Connection refused
