http.proxy.schema.inline

http.proxy.schema.inline

Listens on https port 7143 and will response back whatever is hosted in nginx on that path after enforcing validation.

Requirements

• bash, jq, nc
• Kubernetes (e.g. Docker Desktop with Kubernetes enabled)
• kubectl
• helm 3.0+

Setup

The setup.sh script:

• installs Zilla and Nginx to the Kubernetes cluster with helm and waits for the pods to start up
• copies the web contents to the Nginx pod
• starts port forwarding

./setup.sh

output:

+ ZILLA_CHART=oci://ghcr.io/aklivity/charts/zilla
+ NAMESPACE=zilla-http-proxy-schema-inline
+ helm upgrade --install zilla oci://ghcr.io/aklivity/charts/zilla --namespace zilla-http-proxy-schema-inline --create-namespace --wait [...]

+ sleep 1
+ nc -z localhost 7143
Connection to localhost port 7143 [tcp/*] succeeded!

Verify behavior for valid content

curl --cacert test-ca.crt https://localhost:7143/valid.json

output:

{
    "id": 42,
    "status": "Active"
}

Verify behavior for invalid content

curl --cacert test-ca.crt https://localhost:7143/invalid.json

output:

curl: (18) HTTP/2 stream 1 was reset

Teardown

The teardown.sh script stops port forwarding, uninstalls Zilla and Nginx and deletes the namespace.

./teardown.sh

output:

+ pgrep kubectl
58110
+ killall kubectl
+ NAMESPACE=zilla-http-proxy-schema-inline
+ helm uninstall zilla nginx --namespace zilla-http-proxy-schema-inline
release "zilla" uninstalled
release "nginx" uninstalled
+ kubectl delete namespace zilla-http-proxy-schema-inline
namespace "zilla-http-proxy-schema-inline" deleted
