I switched my project (node.js + mongodb) from Openshift v2 to v3. Also I'm using Starter version of v3 for my project and web console for all configurations.
Deploy results in failed status with following error:
--> Scaling tmo-9 to 1
error: update acceptor rejected tmo-9: pods for rc 'tmoolympus/tmo-9' took longer than 600 seconds to become available
Pod's log:

Second log shows that server is up and running, however application isn't available and it tries recreating deployment for few more times before stopping - The container nodejs-mongo-persistent is crashing frequently. It must wait before it will be restarted again.
.
Question: Is it fault on my side or Openshift v3?
There are 2 issues going on. First, I'm assuming you deployed the nodejs-mongo-persistent
template, which defines a readinessProbe
and livenessProbe
that look for a /pagecount
URL and will not consider your pod healthy until it finds that page. I would recommend either removing those probes, or adjusting them to look at a URL in your codebase.
Second, your application seems to be listening to 127.0.0.1
which won't allow your application to be externally accessible. Seeing as this was based on v2, I would recommend creating an environment variable in v3, OPENSHIFT_NODEJS_IP
, and set it to 0.0.0.0
. These environment variables are no longer necessary in v3, as you can just set any application to 0.0.0.0
and have it be accessible (with an appropriate route).
