Helm uses a packaging format called charts. A chart is a collection of files that describe a related set of Kubernetes resources. Talk to us to get a custom-made chart to install Mayil (with configuration details unique to your installation).

​
Prerequisites

  1. Install Helm CLI
  2. Create a Kubernetes cluster and set Kubectl to that cluster
  3. A subdomain to host Mayil
  4. Receive a custom Helm chart from us

​
Setup HTTPS ingress

We will use cert-manager- github.com/cert-manager/cert-manager Add the Jetstack chart - 
helm repo add jetstack https://charts.jetstack.io
Setup cert-manager - 
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.13.3/cert-manager.crds.yaml

helm install cert-manager jetstack/cert-manager --namespace default --version v1.13.3

​
Configuring Helm

You should have received a zip file from us containing a .tgz file. This is the helm chart. And a values.yaml with configuration options for Helm. Update these values-
  1. ingress.hosts.host- The subdomain where Mayil will be hosted such as mayil.companyname.com
  2. envVars.LINK_TO_MAYIL - The same subdomain as in ingress.hosts.host
  3. certManager.email- The email through which HTTPS certificates will be issued. No account set up or configuration is required. This is simply for record keeping by the certificate issuer.
values.yaml contains sensitive information. Please keep it safe. Save envVars.CLIENT_ID and envVars.CLIENT_SECRET as this will be the default username and password for Vault (used to configure Mayil)

​
Installing Milvus

helm install mayil <path to helm chart> -f values.yaml
The helm chart should be in the installation package you receive as a .tgz file.

​
Check cluster status

Investigate all the pods are running with- 
kubectl get pods
A successful install should look like this- 
kubectl get pods

Investigate ingress with- 
kubectl get ingress
A successfull intall should look like this- 
kubectl get ingress

NAME            CLASS   HOSTS           ADDRESS          PORTS     AGE
mayil-ingress   nginx   aug5.mayil.ai   172.214.14.253   80, 443   4d20h
The IP adress under ADDRESS is the IP address Mayil is connected to. We will link this IP to our subdomain in the next step

​
Connect subdomain

Setup a DNS A record with your domain provider such as the example below using the information from runnning kubectl get ingress from the previous step- 
Host name - aug5.mayil.ai
Value - 172.214.14.253
TTL - 30 Minutes
