Task 1: Create a project jumphost instance

Navigation menu > Compute engine > VM Instance


Task 2: Create a Kubernetes service cluster

gcloud config set compute/zone us-east1-b

gcloud container clusters create nucleus-webserver1

gcloud container clusters get-credentials nucleus-webserver1

kubectl create deployment hello-app --image=gcr.io/google-samples/hello-app:2.0

Task 3: Setup an HTTP load balancer

cat << EOF > startup.sh
#! /bin/bash
apt-get update
apt-get install -y nginx
service nginx start
sed -i -- 's/nginx/Google Cloud Platform - '"\$HOSTNAME"'/' /var/www/html/index.nginx-debian.html

1 .Create an instance template :

gcloud compute instance-templates create nginx-template \
--metadata-from-file startup-script=startup.sh

2 .Create a target pool :

gcloud compute target-pools create nginx-pool

3 .Create a managed instance group :

gcloud compute instance-groups managed create nginx-group \
--base-instance-name nginx \
--size 2 \
--template nginx-template \
--target-pool nginx-pool

gcloud compute instances list

4 .Create a firewall rule to allow traffic (80/tcp) :

gcloud compute firewall-rules create www-firewall --allow tcp:80

gcloud compute forwarding-rules create nginx-lb \
--region us-east1 \
--ports=80 \
--target-pool nginx-pool

gcloud compute forwarding-rules list

5 .Create a health check :

gcloud compute http-health-checks create http-basic-check

gcloud compute instance-groups managed \
set-named-ports nginx-group \
--named-ports http:80

6 .Create a backend service and attach the manged instance group :

gcloud compute backend-services create nginx-backend \
--protocol HTTP --http-health-checks http-basic-check --global

gcloud compute backend-services add-backend nginx-backend \
--instance-group nginx-group \
--instance-group-zone us-east1-b \
--global

7 .Create a URL map and target HTTP proxy to route requests to your URL map :

gcloud compute url-maps create web-map \
--default-service nginx-backend

gcloud compute target-http-proxies create http-lb-proxy \
--url-map web-map

8 .Create a forwarding rule :

gcloud compute forwarding-rules create http-content-rule \
--global \
--target-http-proxy http-lb-proxy \
--ports 80

gcloud compute forwarding-rules list

Error it is showing:-
Please create the managed instance group with 2 nginx web server
How to solve??

• gcloud compute instance-groups managed set-named-ports nginx-group --named-ports http:80 is important step, this should fix the issue

Thanks, I was about to rage at Quicklabs for their buggy checker that didn't recognized them

@Krakoby - Glad it helped.

gcloud compute instance-groups managed set-named-ports lb-backend-group --named-ports http:80 --zone=us-east1-b did it for me (I was receiving the error "Please create the managed instance group with 2 nginx web server" even though the load balancer worked properly)

The comment from SyedFahadShamim also worked for me

write "gcloud container clusters create nucleus-jumphost-webserver1" rather than "gcloud container clusters create nucleus-webserver1"

gcloud config set compute/zone us-east1-b
so
gcloud compute instance-groups managed set-named-ports nginx-group --named-ports http:80
should be
gcloud compute instance-groups managed set-named-ports nginx-group --named-ports http:80 --zone=us-east1-b

"Please verify the web servers are serving on frontend of HTTP(s) Load Balancer"

For this specific error if you have steps right, I think its in the Progress checker the issue is, beside creating the FW Rule with the dynamic name generated in Description, add identically rule:

gcloud compute firewall-rules create web-server-firewall
--allow tcp:80
--network VPC_NAME

Fixed it immediatly for me, so its the name that is the issue

where can I find the VPC_NAME?

where can I find the VPC_NAME?

You can see in VPC Networks in cloud console or with gcloud compute networks list

see https://github.com/Qwiklearning/Challenge-lab/blob/main/GSP313%20Create%20and%20Manage%20Cloud%20Resources:%20Challenge%20Lab

Last Task : gcloud compute forwarding-rules list

if anyone getting error like this:

try this:

gcloud compute target-pools create nginx-pool --region=us-east

I am getting "It doesn't look like you've completed this step yet. Try again." waited for 15-20min. No luck. when I did curl to forwarding-rules IP Address, I am getting html page in return like _"

"_ But not able to finish the challenge. it is stuck at 50 for task3. Not sure what is the issue. Any suggestion to identify the issue?

Use this code for startup.sh

cat << EOF > startup.sh #! /bin/bash apt-get update apt-get install -y nginx sed -i -- 's/nginx/Google Cloud Platform - '"$HOSTNAME"'/' /var/www/html/index.nginx-debian.html service nginx start EOF

Reason:~ in qwiklabs version of code. Server is started before modifying the file, and hence the file does not get modified and you get an error of "Please verify the web servers are serving on frontend of HTTP(s) Load Balancer"

If this helped you, connect with me on LinkedIn https://www.linkedin.com/in/viplavpandhurnekar

thanks a lot bro .......

Even though I finished in sequence the steps u have jot down, I am still facing the error- "Please verify the web servers are serving on frontend of HTTP(s) Load Balancer". Help, please.

Hi, I encountered the same message, I moved on to : "Task 6:Testing traffic sent to your instances", completed it and went back to "Check my progress" for "Create an HTTP load balancer" and then it worked! (Earlier on trying : "gcloud container clusters create nucleus-jumphost-webserver1", Google cloud terminated my lab quoting I wasn't following lab instructions. So I had to redo the lab)

Hi please tell me did you find solution?

It was very helpful. I tried doing this lab watching three different yt tutorials but got a lot of errors. This one worked. Great work.

thanks a lot guys

Thank you for this @Tambunan26 . @namratajanawade thanks as well I also encounter same message after all the load balancing steps and just tested it via browser as described in Task 6.

how you have resolved that error?

How do I rename the firewall rule on shell ?

Im not able to create backend services it says could not fetch resourses

please pass region or zone as argument then try again

Hello guys,

I was doing this lab as well and encountered exactly the same problem list above. Waiting several minutes didn't let me escape from "Earned point: 40" load balancer error. I kept trying and even exhausted my 5 time quota for a specific lab, so I wrote to Qwiki support for help.

Basically they returned some instructions identical to this gist, but these points may help:

1. Watch your startup.sh content.
   The system seems to check your load balancer working by visiting your frontend, cache the page they get, until they see different hostnames. So line 28 sed -i -- 's/nginx/Google Cloud Platform - '"\$HOSTNAME"'/' /var/www/html/index.nginx-debian.html is very important. Do not have an unexpected space or line break in it.
2. Try using VPC network nucleus-vpc instead.
   The Qwiki project is provisioned with two VPC networks.
   Using default VPC network should not effect this lab practically, but I added specification --network nucleus-vpc when creating instance templates and firewall.
3. Click Check my progress AFTER manually browsing your frontend address.
   If your load balancer works correctly, you should be able to connect to your nginx services via the IP listed on gcloud compute forwarding-rules list. Open another browser page and visit it. If you do so right after creating the forwarding rule, you should get an HTTP 404 error, which is normal. Wait and reload until it can gives you 2 versions of Nginx page WITH your backend VM hostname.

Hope you all can defeat this lab! I spent 2 nights on this.

Thanks for this @kingwilly71!

This command resolve the problem, many thanks

@cespirandelli some actions seem to be under the hood there, I am talking about target-pool, url map and a forwarding rule. right?

Thanks bro! 🥇

I was getting the error "Please create the managed instance group with 2 nginx web server" after doing everything, and using the command gcloud compute instance-groups managed set-named-ports YOUR_MANAGED_INSTANCE_GROUP_NAME --named-ports http:80 --zone=YOUR_ZONE solved it for me and I could get the final check in the lab.

Thank you so much for this. This worked for me. Thanks a bunch!
