我构建了自己的nginx图像。我可以用docker运行它并连接到端口8080
docker run -d -p 8080:8080 nginx_image
curl localhost:8080/index.php
Hello Michael
然后我推动此图像制作图像流并从中创建应用程序。
#tag and push stuff not displayed
oc new-app --image-stream=nginx_image
按预期创建dc，svc，rc和pod：
oc get all -l app=nginximage
NAME REVISION DESIRED CURRENT TRIGGERED BY
deploymentconfigs/nginximage 2 1 1 config,image(nginx_image:latest)
NAME READY STATUS RESTARTS AGE
po/nginximage-2-ncv2l 1/1 Running 0 12m
NAME DESIRED CURRENT READY AGE

NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
svc/nginximage 172.30.169.72 <none> 8080/TCP 15m
但是我无法从群集中的节点连接到该服务
curl 172.30.169.72:8080
curl: (7) Failed connect to 172.30.169.72:8080; Connexion refusée
与工作的ruby应用程序进行比较后，我没有看到任何差异。现在我真的看不出如何解决这个问题。

按照Will Gordon的建议，我尝试在吊舱内卷曲，再次连接被拒绝。
oc rsh nginximage-2-ncv2l
# curl localhost:8080
curl: (7) Failed to connect to localhost port 8080: Connection refused
仍然在pod内我试着看到哪个端口被打开
# netstat -tulnp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
none ......以及正在运行的进程

Nginx在这里，但没有收听任何端口，很奇怪......
如果我与群集外的docker容器进行比较
docker exec -it romantic_poitras bash
# curl localhost:8080/index.php
Hello Michael
# netstat -tulnp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 8/nginx
tcp6 0 0 :::8080 :::* LISTEN 8/nginx
Nginx正在收听预期的8080端口。为什么在openshift中部署nginx进程不会监听任何端口？它是否与我必须在ssc anyuid中添加serviceAccount这一事实有关？
