Environment Checker Function Image

This images compares the payload info with the header.

Requirements

• IronFunctions API

Development

Building image locally

# SET BELOW TO YOUR DOCKER HUB USERNAME
USERNAME=YOUR_DOCKER_HUB_USERNAME

# build it
./build.sh

Publishing to DockerHub

# tagging
docker run --rm -v "$PWD":/app treeder/bump patch
docker tag $USERNAME/func-checker:latest $USERNAME/func-checker:`cat VERSION`

# pushing to docker hub
docker push $USERNAME/func-checker

Testing image

./test.sh

Running it on IronFunctions

Let's define some environment variables

# Set your Function server address
# Eg. 127.0.0.1:8080
FUNCAPI=YOUR_FUNCTIONS_ADDRESS

Running with IronFunctions

With this command we are going to create an application with name checker.

curl -X POST --data '{
    "app": {
        "name": "checker",
    }
}' http://$FUNCAPI/v1/apps

Now, we can create our route

curl -X POST --data '{
    "route": {
        "image": "'$USERNAME'/func-checker",
        "path": "/check",
        "config": { "TEST": "1" }
    }
}' http://$FUNCAPI/v1/apps/checker/routes

Testing function

Now that we created our IronFunction route, let's test our new route

curl -X POST --data '{ "env_vars": { "config_test": "1" } }' http://$FUNCAPI/r/checker/check
