eksctl install was not present
eksctl install was not present in initial config. Thus https://www.appmeshworkshop.com/prerequisites/bootstrapsh/ failed.

Creating the EKS Cluster

Ruby Frontend fails to contact backend services after adding Envoy
After deploying the Envoy container to the EC2 instances with State Manager, the frontend loses connectivity to the backend services. Curls to the Backends from the EC2 instances using SSM remote sessions are successful
Nodejs deployment is unsuccessful
kubectl describe pod nodejs-app-76555b7c6b-hhbhz -n appmesh-workshop-ns
Normal BackOff 99s (x5785 over 21h) kubelet, ip-10-0-102-209.us-west-2.compute.internal Back-off pulling image "aws-containers/ecsdemo-nodejs:latest"
The path for installing the eksctl has been changed, provided command does not work
https://www.appmeshworkshop.com/prerequisites/installtools/ affected page
user:~/environment $ curl --silent --location "https://github.com/weaveworks/eksctl/releases/download/latest_release/eksctl_$(uname -s)_amd64.tar.gz" | tar xz -C /tmp
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
user:~/environment $ uname -s
Linux
Workaround:
curl --silent --location "https://github.com/eksctl-io/eksctl/releases/latest/download/eksctl_$(uname -s)_amd64.tar.gz" | tar xz -C /tmp
Command to install the mesh controller does not work
The command here: https://www.appmeshworkshop.com/mesh_nodejs/install_appmesh_controller/ right after the sentence "Now install App Mesh Controller into the appmesh-system namespace using the project’s Helm chart, specifying the service account you just created" does not work. it Returns:
Error: Kubernetes cluster unreachable: exec plugin: invalid apiVersion "client.authentication.k8s.io/v1alpha1"
Workaround - use helm v3.8.2
curl -L https://git.io/get_helm.sh | bash -s -- --version v3.8.2
And to make sure that this will work you need to use kubectl Client Version: v1.16.8
Header-based routing doesn't work
There are issues running the commands in: https://www.appmeshworkshop.com/policyrouting/curljson/
curl --location --header "canary_fleet: true" --silent $URL/json gives 404 error as there is no /json path
Even though header is set to canary_fleet: true, Crystal service still randomly gives non-canary response back. This is probably because Ruby front-end does not forward the header to Crystal service. The only reliable way to get 100% canary response is to open a Session Manager session against the External EC2 instance and access the Virtual Gateway of the Crystal service (created in in https://www.appmeshworkshop.com/virtualgateway/crystal-ingress/) i.e.
for ((i=1;i<=15;i++)); do
curl --header "canary_fleet: true" $NLB_ENDPOINT/ecs/crystal
sleep 1s
done

ERROR: Error installing rubygems-update:

rubygems-update requires Ruby version >= 2.6.0. The current ruby version is 2.5.0.

Workaround:
Commenting out the gem update --system as it causes bootstrap failure
Deployment Strategies/Update the Crystal Code - patch failure
Where: https://www.appmeshworkshop.com/deployment/updatecrystal/
git -C ~/environment/ecsdemo-crystal apply add_time_ms.patch results in failure:
error: patch failed: code_hash.txt:1
error: code_hash.txt: patch does not apply

Errors in commands in Virtual Gateway Ingress to NodeJS service page
In page: https://www.appmeshworkshop.com/virtualgateway/nodejs-ingress/
In command Let’s now create our Virtual Gateway manifest file
missing at the end:
kubectl apply -f ~/environment/eks-scripts/app-mesh-virtual-gateway.yml
Moreover in following two command copyable boxes, command output is present.
Front End fails to come up when running the bootstrap steps in "Start The Workshop"
The EC2 instances fail to start the Rails app due to the following error in the user data logs (/var/log/user-data.log):

I manually ran the user data script as root and get the same error. Any attempt to run rails produces the same error, even rails -v
