Helm support

Helm support for ATS Ingress Controller is still under development and can only be used locally after building the following docker images:

• ats_alpine
• tsexporter

After building the above images, do the following to install ATS Ingress using Helm:

1. $ kubectl create namespace ats-ingress
2. Prepare a self-signed certificate: $ openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout tls.key -out tls.crt -subj "/CN=atssvc/O=atssvc"
3. Create a file named override.yaml which contains the following two values:

tls:
    crt: <TLS certificate>
    key: <TLS key>

4. $ helm install -f override.yaml charts/ats-ingress --generate-name -n ats-ingress

TODO for enabling Helm

• [ ] Upload ats_alpine docker image to a public repository and make corresponding changes to image.repository value in values.yaml
• [ ] Upload trafficserver-exporter docker image to a public repository and make corresponding changes to ats.exporter.image.repository value in values.yaml
• [ ] Hosting the helm chart on github page. Follow the chart repository guide.
