Bicep is declarative - Resources reconcile to desired state
Remote builds tag uniquely - Image tags include deployment timestamp
ACR reuses layers - Only changed layers upload
Preserving Manual Changes
Custom domains added via Portal can be lost on redeploy. Preserve with hooks:
hooks:
preprovision:
shell: sh
run: |
# Save custom domains before provision
if az containerapp show --name "$FRONTEND_NAME" -g "$RG" &>/dev/null; then
az containerapp show --name "$FRONTEND_NAME" -g "$RG" \
--query "properties.configuration.ingress.customDomains" \
-o json > /tmp/domains.json
fi
postprovision:
shell: sh
run: |
# Verify/restore custom domains
if [ -f /tmp/domains.json ]; then
echo "Saved domains: $(cat /tmp/domains.json)"
fi
Handling Existing Resources
// Reference existing ACR (don't recreate)
resource containerRegistry 'Microsoft.ContainerRegistry/registries@2023-07-01' existing = {
name: containerRegistryName
}
// Set customDomains to null to preserve Portal-added domains
customDomains: empty(customDomainsParam) ? null : customDomainsParam
Container App Service Discovery
Internal HTTP routing between Container Apps in same environment:
// Backend reference in frontend env vars
env: [
{
name: 'BACKEND_URL'
value: 'http://ca-backend-${resourceToken}' // Internal DNS
}
]
hooks:
postprovision:
shell: sh
run: |
PRINCIPAL_ID="${BACKEND_PRINCIPAL_ID}"

az role assignment create \
--assignee-object-id "$PRINCIPAL_ID" \

--scope "$OPENAI_RESOURCE_ID" 2>/dev/null || true

Critical Reminders
Always use remoteBuild: true - Local builds fail on M1/ARM Macs deploying to AMD64
