Add k8s-apache-module deployment with Fastly NGWAF integration

[Copilot]

Adds a Kubernetes deployment example for Apache with the Fastly NGWAF module on Ubuntu, with the agent running as a sidecar container.

Changes

• Dockerfile: Ubuntu 24.04 with Apache2 and sigsci-module-apache installed
• deployment.yaml:
  • ConfigMap with NGWAF module config pointing to Unix socket
  • Two-container pod: Apache + sigsci-agent sidecar
  • Shared emptyDir volume for socket communication at /sigsci/tmp/sigsci.sock
  • NodePort service exposure
• Makefile: Standard build/deploy/demo targets matching existing patterns
• README.md: Quickstart and architecture docs

Usage

export NGWAFACCESSKEYID="..."
export NGWAFACCESSKEYSECRET="..."
make docker
make rebuild
make demo  # then curl 127.0.0.1:8080

Follows the same patterns as k8s-nginx-module-agent.

Original prompt

You need to build a minimalist k8s example using apache.

k8s-apache-module

The implementation should use the Fastly NGWAF module running on Ubuntu. On the same container, the NGWAF Agent should be running.

Follow similar design patterns as the other deployments in the directory on-prem-ngwaf-integrations.
