Debugging Pilot with Delve

First build pilot with GCFLAGS="all=-n -l":

GCFLAGS="all=-N -l" HUB=docker.io/slandow TAG=slandow BUILD_IN_CONTAINER=1 make docker.pilot

Then we can wrap that image in one that includes delve:

stevenctl

# sets up a, b, c deployments with services for a and b

kind: Service

    app: a

stevenctl

# scales deployment a to 500 replicas

apiVersion: apps/v1

stevenctl

# triggers a new "b" pod to be created

Writing Good Tests

Keeping test times low

Re-use echos

Spinning up services for tests is one of the slower pieces of writing a test. Wherever possible, keep this setup in your suite's Setup to avoid long test times.
