faas-content-proxy

A service to proxy a GET requests to a FaaS POST event and parse the response back into HTML content.

Designed to be used with the AWS lambda container and 11ty project.

This is currently not meant to be an internet facing webserver and should be deployed with a caching layer and TLS termination etc.

usage

Step 1. Build the project

cargo build --release

Step 2. Edit the knative.toml

If you are just running the demo project https://github.com/No9/eleventy-serverless-docker then the toml file will be fine. Otherwise review the following settings in knative.toml

[build]
# if you want to publish content you can by pointing to a folder.
publish = "public"

[errorpages]
# Currently only custom 404 and 500 are supported.
not_found = "404.html"
internal_server_error = "500.html"

[[headers]]
  # Define which paths this specific [[headers]] block will cover.
  for = "/*"

  [headers.values]
    X-Frame-Options = "DENY"
    X-XSS-Protection = "1; mode=block"
    Content-Security-Policy = "frame-ancestors https://www.facebook.com"

    # Multi-value headers are expressed with multi-line strings.
	cache-control = '''
	max-age=0,
	no-cache,
	no-store,
	must-revalidate'''

[[redirects]]
# this section matches routes to a serverless function.
from = "/:slug/"
to = "http://127.0.0.1:8080/2015-03-31/functions/function/invocations"

Step 3. Run an 11ty serverless instance.

If your just taking a look then start an instance of https://github.com/No9/eleventy-serverless-docker#step-3-create-container

Step 4. View the dynamic content.

Open a web browser at http://localhost:8090/1/ or http://localhost:8090/1/

run the whole project in podpman

If you have podman installed then the whole demo can be ran as follows:
