Unimatrix-Zero

Unimatrix-Zero is a set of "FaaS runtimes" to deploy quickly small functions on Knative and benefit of all qualities of Knative (serving and eventing).

eventing part is in progress

🖐️ Unimatrix-Zero runtimes are only intended to experiments easily with Knative

Requirements

• Knative serving
• Knative eventing (right now, optional)
• Install kn (the Knative CLI)

Runtimes

• JavaScript: javascript/README.md
• Kotlin: kotlin/README.md
• GraalVM: polyglot/README.md (JavaScript, Ruby, Python)

Example: JavaScript (NodeJS)

Right now, it's the only one.

How to use it

Create a function

docker_user="k33g"
service="hello-node"
namespace="k-apps" # create the namespace before

read -d '' CODE << EOF
let hello = params => {
  return {
    message: "👋 Hello World 🌍",
    total: 42
  }
}
EOF

kn service create ${service} \
--namespace ${namespace} \
--env FUNCTION_NAME="hello" \
--env FUNCTION_CODE="$CODE" \
--env README="# Hello World" \
--image docker.io/${docker_user}/unimatrix-zero-javascript:latest \

kn revision list -s ${service} -n ${namespace}
kn route list -n ${namespace}  

Call the hello function:

curl -d '{"name":"Bob Morane"}' \
-H "Content-Type: application/json" \
-X POST http://unimatrix-zero-js-hello.k-apps.192.168.64.70.xip.io

Remark: if you use a GET request, you'll get the content of the README environment variable

Update the function

read -d '' CODE << EOF
let hello = params => {
  return {
    message: "👋 Hello World 🌍",
    total: 42,
    params: params
  }
}
EOF

kn service update ${service} \
--namespace ${namespace} \
--env FUNCTION_CODE="$CODE" \
--image docker.io/${docker_user}/unimatrix-zero-javascript:latest
