Google Container Engine (GKE): "Hello Wordpress" tutorial not working (ERR_CONNECTION_REFUSED)

Question

I'm trying to setup example from Running Wordpress with a Single Pod.

• I've done Before You Begin section:

$ gcloud config list

[compute]
zone = europe-west1-c
[core]
account = [email protected]
disable_usage_reporting = False
project = com-project-default

• I've done the steps from the tutorial:

  "Step 1: Create your cluster" logs here

  "Step 2: Create your pod" logs here

  "Step 3: Allow external traffic" logs here

• More logs:

  $kubectl get pods - log (toggle text wrapping)

  $gcloud compute firewall-rules list - log

So, when I try to connect to http://104.155.7.213/ I'm receiving "This web page is not available: ERR_CONNECTION_REFUSED".

I tried to add "Allow HTTP traffic" explicitly to the node in Compute Engine VMs dashboard and also I tried to use "kubectl run" instead of deprecated "kubectl run-container", but it doesn't help. Also sometimes I'm receiving "last termination: exit code 2" (1 or 2) in "message" column when run "kubectl get pods" (but not this time)`

Thank you for your help in advance!

If you want to access the container directly using the node VM's IP address, you need to specify a host port in addition to a container port, e.g. kubectl run-container wordpress --image=tutum/wordpress --port=80 --hostport=80

Alternatively, you can access wordpress via the proxy running on the master by running kubectl proxy and then pointing your web browser at http://localhost:8001/api/v1beta3/proxy/namespaces/default/pods/wordpress-3gaq6.
