Re: Issue by installing OKD OpenShift 3.11



Hi,


As a general rule, you may want to check for the corresponding container health and logs.

You won't find any apache or nginx listening. The process serving on :8443 is openshift, it should be started in a container.
Note that the master-api container, in charge of that service, closely rely on another container: etcd. Which is what ansible's waiting for, in your logs.

On the master node, use "docker ps" (worst case scenario, "docker ps -a").
Locate your etcd and master-api containers ID (first column).
Then use "docker logs [-f] <container-id>", search for errors.

You may find file copies of these logs in /var/log/containers (and /var/log/pods).

Let us know how that goes.

And try to avoid mailing your htpasswd entries ;)


Regards.

Dear Team,

I've encountered some issue to installing openshift (okd 3.11) on 3 vms (1 master and 2 nodes).
I followed the recommendations and procedure as described in docs.
Then I launched the ansible prerequiste playbook without issue, all was fine. But unfortunately the deploy_cluster playbook didn't finished.
Some errors appears when he start the pod.

Regarding this issue, I've checked the master server and I didn't seen the http port 8443 open or no http/nginx/or whatever service are running, strange.....


DNS server was installed on a vm called services and the dig command was ok.

 

Please let me know if I failed to install something or is the inventory config wrong? what should I do to troubleshoot this problem?

Thanks and best regards, J.
