Envoy Azure Functions filter

This project links an Azure Functions HTTP filter with the Envoy binary. A new filter io.solo.azure_functions which redirects requests to Azure Functions is introduced.

Building

To build the Envoy static binary:

$ bazel build //:envoy

Testing

To run the all tests:

$ bazel test //test/...

To run the all tests in debug mode:

$ bazel test //test/... -c dbg

To run integration tests using a clang build:

$ CXX=clang++-5.0 CC=clang-5.0 bazel test -c dbg --config=clang-tsan //test/integration:azure_functions_filter_integration_test

E2E

For the e2e test, your Azure Function App requires a function named "uppercase". Its source code can be found in e2e/uppercase.cs.

To run the e2e test:

$ echo "<yourapp>" > ~/tmp/azure-app
$ echo "<ApiKey>" > ~/tmp/azure-api-key
$ bazel test //e2e/...
