Introduction
In this article we will implement the CI/CD for the Azure API Management Service.
Azure API Management is a reliable, secure and scalable way to publish, consume and manage API's.
DevOps Architecture
Technology Used
GitHub, GitHub Actions
Python, REST API, ARM template
APIM Component
As part of the CI/CD, Below list of the component can be deployed.
APIs
Backends
NamedValues
Operations
Operations Policies
APIs policies
This can be customizable through Python Script to deploy only required component as per your requirement.
Code Snippet of Python Script.
# Change to True for Deploy else set False
deploy_apis=True
deploy_namedValues=False
deploy_backends=False
deploy_operations=True
deploy_policies=True
deploy_ops_policies=True
Component Deployment Sequence
Configuration Update
There might be some configuration that needs to be updated before Deploying to environment. For that We have created Python script which will update the ARM template with respect to environment Value specified in the properties File.
Python Script Details
Properties File Like
Setup Repo for CI/CD
As per the discussed method we can setup the CI/CD workflow. All the project related script and File is publicly available at.
Now lets setup each Part one by One.
Repo Setup
First we need to make sure the ARM template extracted from the Dev API Management Service and Imported to GitHub. Once you extract the ARM template there will be Two Files but we only required template.json File to be imported.
Properties Update
Next we need to see what are the Properties needs to be updated before we deploy to the Pre Prod and Prod. Since we extracted the template from Dev APIM all the configuration related to dev will be available in the ARM template. Hence to Deploy on other environment we need to update the ARM template and that will be achieved through Developed Python script.
In this case review the template and update the below files.
Example:
If you see the below example we are using the properties file where left value will be replaced by Right Value.
Deployment Script
You can fork the Deployment script and properties python script along with requirement.txt file and import to your Repo.
Workflow File
Since we are using the GitHub Actions for Demo you can get the Workflow file and Import to GitHub Account.

Azure Service Principle
For all the authentication we are using the Service Principle so if you want to use the same please create SP and set the Permission to access to API Management service and Key Vault
KeyVault
In the workflow we are using the Key Vault to fetch the below required details. Make sure the Key Vault access policies setup to access by Service Principle
