Resource group: aca-demo

👉 Deploy App Configuration and Key Vault with ./deploy/deploy_kv.sh

👉 Deploy ACA Environment, Log Analytics and App Insights with commands in ./demos/demo1-single/commands.md (link)

👉 Deploy container app with commands from ./demos/demo1-single/commands.md (link)

Demonstrate:

• Container App is deployed
• Logs are streamed to Log Analytics
• Ingress is configured
  • HTTP ingress
  • TCP ingress requires a vnet
• There is one revision
• Making a change to the container results in a new revision
  • change the container tag and environment variable WELCOME
• Explain single and multiple revision mode
• Enable multiple revisions
• Split traffic 50/50 between revisions

👉 Deploy worker with az containerapp up (see ./worker/README.md) (link)

Example command:

az containerapp up -n worker -g $RG --environment $ENVNAME \
    --source . -l westeurope

Demonstrate:

• Python image with the code is built by a new ACR instance
• Worker is deployed with image from ACR
• There is no ingress
• Look at the realtime logs and point out there are errors
• Look at the worker code in app.py
  • it needs an environment variable AZURE_APPCONFIGURATION_ENDPOINT
  • that variable needs the endpoint of the App Configuration instance
  • show the App Configuration instance in the portal and the value to retrieve
• Demonstrate the use of Linked Services (preview)
  • add the App Configuration instance as a linked service
  • it configures managed identity and the environment variable
  • the environment variable gets it value from the Container App secret
  • show the logs: useful work is done with the value 😉

Note: we can modify the source code and run az containerapp up again to update the container app

👉 Deploy service bus with commands from ./demos/demo3-scale/commands.md (link)

👉 Deploy container app with commands from ./demos/demo3-scale/commands.md (link)

Deployment is done with Bicep:

RG=aca-demo
LOCATION=westeurope

az deployment group create --resource-group $RG --template-file ./main.bicep --parameters parLocation=$LOCATION

Demonstrate:

• Service Bus namespace is deployed and topic created (mytopic)
• Container App is deployed
• Dapr component is deployed and scoped to the container app
• There is no ingress
• Scaling is configured with a custom service bus topic scaler
• Show the logs, including the Dapr logs
• Send messages to the topic

👉 Deploy Cosmos DB with commands from ./demos/demo4-multi/commands.md (link)

👉 Deploy frontend container app with commands from ./demos/demo4-multi/commands.md (link)

👉 Deploy backend container app with commands from ./demos/demo4-multi/commands.md (link)

⚠️ Backend needs Cosmos DB to be fully deployed; frontend can be deployed any time

Demonstrate:

• Cosmos DB is deployed with a container to save state with key/value pairs
• Dapr component is deployed and scoped to the container app
• Frontend is deployed with ingress
• Backend is deployed without ingress
• Frontend will call backend to store data in Cosmos DB
• Show the logs
• Start app.py to send messages to the front end

⚠️ For app.py to work, you need the FQDN of the frontend container app:

Retrieve the FQDN from an Azure Container Apps with the Azure CLI:

RG=aca-demo
APPID=$(az containerapp show -g $RG -n frontend | jq .id -r)
export FQDN=$(az containerapp show --ids $APPID | jq .properties.configuration.ingress.fqdn -r)
