Debugging via Intellij / VSCode

This section describes how to debug Deck locally by running it inside VSCode or Intellij.

# Prepare assets
make -C prow build-tarball PROW_IMAGE=prow/cmd/deck
mkdir -p /tmp/deck
tar -xvf ./_bin/deck.tar -C /tmp/deck 
cd /tmp/deck
# Expand all layers
for tar in *.tar.gz; do tar -xvf $tar; done

# Start Deck via go or in your IDE with the following arguments:
--config-path=./config/prow/config.yaml
--job-config-path=./config/jobs
--hook-url=http://prow.k8s.io
--spyglass
--template-files-location=/tmp/deck/var/run/ko/template
--static-files-location=/tmp/deck/var/run/ko/static
--spyglass-files-location=/tmp/deck/var/run/ko/lenses
