Deploying pixie is a bit tricky and doesn't work out of the box yet. First you have to create an account on https://work.withpixie.ai/ and create an API key.

# Install pixie CLI
bash -c "$(curl -fsSL https://withpixie.ai/install.sh)"
# Authenticate with the API key
px auth login --manual
# Deploy the pixie stuff (make sure the current context is minikube beforehand!)
px deploy

This will take some time. Pixie sends it's collected data to https://work.withpixie.ai/ where you can run queries against the data.

The pixie datasource in grafana doesn't work yet. Please create a new dataource for your purposes.
