build_push.yaml

# This workflow:
# * Builds, tests, and scans all images
# * (optionally) pushes the images to ACR
#
# This workflow triggers on:
# * a push to master
# * any create/synchronize to a PR (eg: any time you push an update to a PR).
#
# Image build/test/scan will run on any of the above events.
# Image push will run only if:
# * this is a push to master
# * if the PR triggering this event has the label 'auto-deploy'
#
# To configure this workflow:
#
# 1. Set up the following secrets in your workspace:
#     a. REGISTRY_USERNAME with ACR username
#     b. REGISTRY_PASSWORD with ACR Password
#     c. AZURE_CREDENTIALS with the output of `az ad sp create-for-rbac --sdk-auth`
#     d. DEV_REGISTRY_USERNAME with the DEV ACR username
#     e. DEV_REGISTRY_PASSWORD with the DEV ACR Password
#
# 2. Change the values for the REGISTRY_NAME, CLUSTER_NAME, CLUSTER_RESOURCE_GROUP and NAMESPACE environment variables (below in build-push).
