Lab 8.1 - Helm/Apache Pending external IP assignment.

krzysztofcyran93

I am experiencing an issue with Helm/Apache chart

helm install anotherweb .
NAME: anotherweb
LAST DEPLOYED: Tue Oct  7 11:26:09 2025
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
CHART NAME: apache
CHART VERSION: 11.4.29
APP VERSION: 2.4.65

⚠ WARNING: Since August 28th, 2025, only a limited subset of images/charts are available for free.

    More info at https://bitnami.com and https://github.com/bitnami/containers/issues/83267

** Please be patient while the chart is being deployed **

1. Get the Apache URL by running:

** Please ensure an external IP is associated to the anotherweb-apache service before proceeding **
** Watch the status using: kubectl get svc --namespace default -w anotherweb-apache **

  export SERVICE_IP=$(kubectl get svc --namespace default anotherweb-apache --template "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}")
  echo URL            : http://$SERVICE_IP/


WARNING: You did not provide a custom web application. Apache will be deployed with a default page. Check the README section "Deploying your custom web application" in https://github.com/bitnami/charts/blob/main/bitnami/apache/README.md#deploying-a-custom-web-application.

WARNING: There are "resources" sections in the chart not set. Using "resourcesPreset" is not recommended for production. For production installations, please set the following values according to your workload needs:
  - resources

It doesn't want to assign the external IP

kubectl get svc --namespace default -w anotherweb-apache
NAME                TYPE           CLUSTER-IP     EXTERNAL-IP   PORT(S)                      AGE
anotherweb-apache   LoadBalancer   10.109.39.75   <pending>     80:31450/TCP,443:31639/TCP   102s

The logs are saying it cannot pull the image

kubectl logs anotherweb-apache-687bd9c775-rl9qv --all-containers
Error from server (BadRequest): container "preserve-logs-symlinks" in pod "anotherweb-apache-687bd9c775-rl9qv" is waiting to start: trying and failing to pull image

I tried the tag "latest" but it didn't help

It only works when allowing insecure image:

helm install anotherweb bitnami/apache \
  --set image.repository=bitnamilegacy/apache \
  --set image.tag=2.4.65-debian-12-r2 \
  --set global.security.allowInsecureImages=true

After a while the pod is running, but it doesn't want to assign the external IP.

ubuntu@k8scp:~/apache$ kubectl get svc --namespace default -w anotherweb-apache
NAME                TYPE           CLUSTER-IP    EXTERNAL-IP   PORT(S)                      AGE

anotherweb-apache   LoadBalancer   10.99.22.42   <pending>     80:31316/TCP,443:31813/TCP   34m

So I can't get the service ip:

export SERVICE_IP=$(kubectl get svc --namespace default anotherweb-apache --template "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}")
error: error executing template "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}": template: output:1:10: executing "output" at <index .status.loadBalancer.ingress 0>: error calling index: index of untyped nil

echo URL            : http://$SERVICE_IP/
URL : http://Error executing template: template: output:1:10: executing "output" at <index .status.loadBalancer.ingress 0>: error calling index: index of untyped nil. 

I've waited for over an hour and still nothing.
I'm on AWS EC2 and followed setup with Cillium. Happy to post command outputs if necessary

Hi @krzysztofcyran93,

Thank you for identifying the additional flags needed to deploy the bitnami/apache chart. I shall forward your findings to our course maintainer.

The class lab environment setup is not configured for external IP assignment in the case of LoadBalancer service type, so the pending state is normal. To access the webserver app, you have different options:

• Logged into either node, you can use curl from a terminal, targeting the cluster IP (10.99.22.42) of the service exposing the anotherweb application, and port 80. It would be something like $ curl 10.99.22.42:80
• From your workstation, you can use curl from a terminal, targeting the public IP of either cloud VM (it should work with cp and with worker public IP addresses), and node port 31316 (according to your output above). It would be something like $ curl 35.45.55.65:31316 (where your public IP will be different).
• From your workstation, from a browser, send an http:// request to the public IP of either cloud VM (it should work with cp and with worker public IP addresses), and port node 31316 (according to your output above). Assuming the same dummy public IP from above http://35.45.55.65:31316.

Regards,
