Update AWS EKS Letsencrypt Cluster Issuer for Cert Manager

[ciro-brent]

Bug Report

Please provide information about your setup

• formsflow.ai Version: Unsure, but I believe forms-flow-ai-charts say 3.0.1
• Browser: Google Chrome
• Browser version: Version 115.0.5790.170

Steps to Reproduce

1. Complete through Step 5 of AWS EKS Procedures where you provide a command:
   kubectl apply --validate=false -f https://github.com/jetstack/cert-manager/releases/download/**v1.0.1**/cert-manager.yaml

2. When completing Step 6 of the EKS Procedures, kubectl apply -f letsencrypt-issuer.yml (the file sample you provide with the email replaced) - failed with the following observed behavior

Observed Behaviour

Error after applying "letsencrypt-issuer.yml" from
"Error from server (InternalError): error when creating "letsencrypt-issuer.yml": Internal error occurred: failed calling webhook "webhook.cert-manager.io": failed to call webhook: Post "https://cert-manager-webhook.cert-manager.svc:443/mutate?timeout=10s": tls: failed to verify certificate: x509: certificate signed by unknown authority"

Expected Behaviour

Should have received a "clusterissuer.cert-manager.io/forms-flow-idm created"

I had to apply two fixes to the process to get this to work:

Update cert-manager version number to the latest version (or at least more recent that v1.0.1. I check their site and v1.12.3 was the most recent release, so the Step 5 was updated to:
kubectl apply --validate=false -f https://github.com/jetstack/cert-manager/releases/download/**v1.12.3**/cert-manager.yaml

Also, this cert-manager.io page shows that the letsencrypt-issuer.yml file should have one change. (See: https://cert-manager.io/docs/configuration/acme/http01/ ). Since version 1.12 of cert manager, within the solver section of the ACME specs: the last line of the file you provided should set - http01:ingress:ingressClassName and not http01:ingress:ingress. If I had tested cert-manager v1.11, it may not have required the "ingressClassName", but all of the cert-manager documentation references this version of the software.
