bicep-on-k8s

This is a demo of using Bicep extensibility to deploy a dotnet application to a Kubernetes cluster. The application itself allows you to build a .bicep file via HTTP request. The build & deployment process is fully automated via GitHub Actions.

Setting up the environment

  1. Fork this repo, open the forked repo in Codespaces
  2. Open ./initial_setup.sh and modify the values of repoOwner, repoName, rgName & rgLocation
  3. Log in to Az CLI
  4. Run ./initial_setup.sh <tenantId>, <subscriptionId>
  5. The output should contain 3 env variables ACR_CLIENT_ID, ACR_SUBSCRIPTION_ID & ACR_TENANT_ID. Save each one as a GitHub Repo Secret.
  6. Modify ./deploy/main.bicepparam to contain desired values for your AKS cluster.
  7. Modify the AKS_RG_NAME variable in ./.github/workflows/cd.yml to match the value of rgName used in step 2.
  8. Push to your main branch. GitHub Actions should build & deploy the .NET application to an AKS cluster!
  9. To test the live service, check the GitHub Actions output for the cluster DNS name. Replace bicepbuild.eastus.cloudapp.azure.com with this value in the testing commands below.

Running locally

  1. Open in Codespaces
  2. Build: 
    docker build -t bicepbuild:latest ./src
  3. Run: 
    docker run -p 8001:80 bicepbuild:latest ./src
  4. Test locally:
    • Build: 
      curl -X POST http://localhost:8001/build \
  -H 'Content-Type: application/json' \
  -d '{"bicepContents": "param foo string"}'
    • Decompile: 
      curl -X POST http://localhost:8001/decompile \
  -H 'Content-Type: application/json' \
  -d '{"template": "{\n  \"$schema\": \"https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#\",\n  \"contentVersion\": \"1.0.0.0\",\n  \"parameters\": {\n    \"foo\": {\n      \"type\": \"string\"\n    }\n  },\n  \"resources\": []\n}"}'

Testing the real service

  • Build: 
    curl -X POST http://bicepbuild.eastus.cloudapp.azure.com/build \
  -H 'Content-Type: application/json' \
  -d '{"bicepContents": "param foo string"}'
  • Decompile: 
    curl -X POST http://bicepbuild.eastus.cloudapp.azure.com/decompile \
  -H 'Content-Type: application/json' \
  -d '{"template": "{\n  \"$schema\": \"https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#\",\n  \"contentVersion\": \"1.0.0.0\",\n  \"parameters\": {\n    \"foo\": {\n      \"type\": \"string\"\n    }\n  },\n  \"resources\": []\n}"}'
