Before deploying, you must export your GITHUB_REPOS, GITHUB_USER and GITHUB_TOKEN to your shell. Then run:
oc process -f templates/github-secret.yaml -p GITHUB_USER=${GITHUB_USER} -p GITHUB_TOKEN=${GITHUB_TOKEN} -p GITHUB_REPOS=${GITHUB_REPOS} | oc apply -f-
oc process -f templates/exporter.yaml -p APP_NAME=commit-exporter | oc apply -f-
Configuration can be found in the config guide.
