Serverless reference implementation guidance

Drone Delivery Serverless

This project contains a reference implementation for two serverless application architectures.

Serverless web application

The application serves static content from Azure Blob Storage, and implements an API using Azure Functions. The API reads data from Cosmos DB and returns the results to the web app.

Serverless event processing

The application ingests a stream of data, processes the data, and writes the results to a back-end database (Cosmos DB).

For more information about these architectures, including guidance about best practices, see the following articles in the Azure Architecture Center:

• Serverless web application

• Serverless event processing using Azure Functions

Deployment

Follow steps here to deploy this reference implementation.

Drone Status Function App CI/CD with Azure DevOps

Add CI/CD to Drone Status using Azure Pipelines with YAML and Azure Functions Slots.

Prerequistes

1. Create Azure DevOps account
2. Add Azure subscription as service connection
3. Optionally, assign service connection application to role, so it is allowed to create new azure resources
4. Create a Github or Azure Repos repository.

Configure CI/CD using Azure Pipelines

Clone and add remote

git clone https://github.com/mspnp/serverless-reference-implementation.git && \
cd serverless-reference-implementation && \
git remote add <remote-name> <remote-url> # this remote url corresponds to the prerequisite step 4th

Export the following environment variables

export SERVICECONNECTION=<service-connection-name> # use the name configured in the 2nd prerequisite step
export LOCATION=<location>
export RESOURCEGROUP=<resource-group>
export APPNAME=<app-name> # less or equal than 6 chars
export SLOTNAME=<slot-name>

Replace Azure Pipeline place holders

sed -i "s#ServiceConnectionName: '<serviceconnection>'#ServiceConnectionName: '$SERVICECONNECTION'#g" azure-pipelines.yml && \
sed -i "s#Location: '<location>'#Location: '$LOCATION'#g"  azure-pipelines.yml && \
sed -i "s#ResourceGroup: '<resourcegroup>'#ResourceGroup: '$RESOURCEGROUP'#g" azure-pipelines.yml && \
sed -i "s#AppName: '<appName>'#AppName: '$APPNAME'#g" azure-pipelines.yml && \
sed -i "s#SlotName: '<slotName>'#SlotName: '$SLOTNAME'#g" azure-pipelines.yml

Push changes to azure repos or github

git push <remote-name> master

Follow instructions below to configure your first Azure Pipeline

Get your first build with Azure Pipelines

Note: this first build will attemp to execute the azurepipeline.yml against master

Trigger the CI/CD pipeline by pushing to staging

git checkout -b staging && \
git push <remote-name> staging

Note: also feature branches are going through the CI pipeline.
