Guidelines for deploying
ci build devops pipeline pipelines
Build process Build Pipelines Quality Build Building the docker image, running tests and checking code. Triggered by:
Pull Request Altinn Studio and Runtime Docker Images Separate pipelines are made for Altinn Studio and Runtime. The pipeline will build and deploy the Altinn Studio Docker Image and the Runtime Docker Image to Azure Container Registry.
Git Merge to Master
Altinn Studio Release Build When the build for either Altinn Studio or Runtime is successfully ran a release build will start. The release build will update the kubernetes cluster with the images created in the Altinn Studio and the Runtime builds
Successfull build of either/both Altinn Studio and Runtime Altinn Service Deploy
Service Runtime docker image bundling process. Building the Altinn Service with “service specific” files from Gitea, creating a “Service Image”, deploying to Azure Container Registry and telling Kubernetes to deploy service.
Build process (Pipeline):
This process have more details in the Dockerfile. This is a summary.
Downloading files from service repo in Gitea
Building Docker base image with Dockerfile. This includes “Dotnet build” for C# files from Gitea. “Dotnet build” is executed on the Runtime Base Image reusing previous. Docker Pull: Altinn/Runtime Base Image with SDK from ACR. This makes the AltinnService build faster. Clone and build code from Gitea inside Altinn-Runtime Base Image. Docker Pull: Microsoft/DotNet AspNetCore. Copy Altinn Runtime, AltinnService Build files and Service Metadata/Resources from Gitea. Publish to ACR. Triggered by:
“Publish Service”-button in Altinn Studio.
Generating Altinn Pipelines Images Summary The Altinn Azure Pipelines Image (image) is built with Packer. The Packer JSON configuration is based on the same configuration used by Microsoft to build their own Hosted Agent images. The image is built in Azure Pipelines passing in “secrets” to the Packer configuration with Environment Variables not visibly available during the build process. Usage Create a Virtual Machine in Azure using the pre built image found under “browse all images and disks”. Create a username and password (should be stored in Azure Vault). Installing Agent Host The script for installing the Agent Host is found at: Maintenance/azure-pipelines-image/scripts/agent/agent-install.sh (Currently a manual job)
A computer can have one or several Agent Hosts installed. Several Agents, on one or several servers, can connect to one Agent Pool.
Creating Pipelines Image with Packer.io
The process of creating an Image with Packer is described here
Some steps might already be performed in Azure.
The variables used in the Packer JSON configuration file is passed in via hidden Pipelines environment variables.
The “light” image only contains Git and Docker and is created for only running Docker images.
Packer creates Resource Groups in Azure keeping the image build for history and debuggind purposes. To remove this Resource Group run AZ Cli:
az group delete -n PackerResourceGroup
