But it's working fine locally or just with the docker commands. It's because
it's a reverse proxy.
But It's just not working in OpenShift. I can show you the deploymentconfigs:

So. Now they're deployed in different services. NodeJS is working fine. It can
run on its own. But Nginx keeps restarting because it's a reverse proxy for the
nodejs. But it can't find the nodejs-container. That's the reason why is
container keep restarting:

I can't see your DeploymentConfiguration, but I believe that since nodejs is a
standalone service, its port is 80, like any other http service:
try changing server nodejs:8888 weight=10 max_fails=3
fail_timeout=30s;
to server nodejs:80 weight=10 max_fails=3 fail_timeout=30s;

I just want to make my problem clear, so that's the reason for this new, longer
message. Thanks . I tried already a lot.
I've created everything new.
So what I've done:
oc new-app image1 --name nginx
oc new-app image2 --name nodejs
See screenshot for the scenario at the moment.
The
nginx-container is in a backoff restart-loop because it can't find
nodejs:8888 (container-name and open port on the container).
Why is nginx searching for this container. Well, take a look to the nginx.conf
events { worker_connections 1024; }
http {
include /etc/nginx/mime.types;
upstream node-app {
least_conn;
server nodejs:8888 weight=10 max_fails=3 fail_timeout=30s;
}
server {
listen 80;
root /usr/share/nginx/html/dist;
location / {
index index.html;
}
location /api {
proxy_pass http://node-app;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
}
So this is working fine when I just ran the containers like this:
docker run --restart=always -d --name "nodejs" image:${version}
docker run --restart=always -d -p 80:80 --name nginx --link nodejs:nodejs
image:${version}
So I tried to put them under the same service, but it did not seem to help.
