ERR_EMPTY_RESPONSE 正在使用 Docker 在 VirtualBox 中安装哨兵

Question

我正在根据 instruction 使用 Docker 安装 Sentry。

我有运行个带有 -p 8080:9000 选项的哨兵：

docker run -d -p 8080:9000 --name my-sentry -e SENTRY_SECRET_KEY='<secret-key>' --link sentry-redis:redis --link sentry-postgres:postgres sentry

我有 ifconfig 的下一个输出：

$ ifconfig
docker0   Link encap:Ethernet  HWaddr 02:42:0b:b2:d5:41  
      inet addr:172.17.0.1  Bcast:0.0.0.0  Mask:255.255.0.0
      inet6 addr: fe80::42:bff:feb2:d541/64 Scope:Link
      UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
      RX packets:123 errors:0 dropped:0 overruns:0 frame:0
      TX packets:78 errors:0 dropped:0 overruns:0 carrier:0
      collisions:0 txqueuelen:0 
      RX bytes:6960 (6.9 KB)  TX bytes:8622 (8.6 KB)

enp0s3    Link encap:Ethernet  HWaddr 08:00:27:6d:a0:12  
      inet addr:192.168.1.207  Bcast:192.168.1.255  Mask:255.255.255.0
      inet6 addr: fe80::a00:27ff:fe6d:a012/64 Scope:Link

      collisions:0 txqueuelen:1000 
      RX bytes:260348 (260.3 KB)  TX bytes:279424 (279.4 KB)
...

所以，我尝试打开 url http://192.168.1.207:8080

浏览器将我重定向到页面 http://192.168.1.207:8080/auth/login/，错误 ERR_EMPTY_RESPONSE。怎么了？我是 Docker 的新人。如何查看可能出现错误消息的日志？

找到解决方案。我运行 docker 容器具有 sentry.conf.py、-e SENTRY_DB_USER=sentry -e SENTRY_DB_PASSWORD=secret:

中描述的环境变量

docker run -p 8080:9000 -d --name my-sentry \ 
    -e SENTRY_SECRET_KEY=$SENTRY_SECRET_KEY \
    -e SENTRY_DB_USER=sentry \
    -e SENTRY_DB_PASSWORD=secret \
    --link sentry-redis:redis --link sentry-postgres:postgres sentry
