k8s-to-azure-container-app 0.1.0

Migrate Kubernetes deployments into Azure Container Apps

K8sToAzureContainerApp

Overview

K8sToAca is a Python tool designed to streamline the process of transitioning Kubernetes namespaces into Azure Container App environments. Leveraging the Kubernetes API, this tool retrieves all deployment objects within the specified namespace and generates Azure Container Apps deployment in YAMLs, JSON or Terraform(in Beta). Additionally, it provides a shell script containing commands necessary for deploying the generated deployment files using the Azure CLI.

Parameters

Parameter	Mandatory	Description
namespace	True	The Kubernetes namespace to be migrated.
context	True	The name of the Kubernetes config context for the cluster.
aca_resource_group	True	The Azure Resource Group where the Container App Environment exists.
aca_environment	True	The name of the Azure Container App Environment.
output	False	Output format values (yaml, json, terraform). Terraform output is in preview. Default value: yaml
outputpath	False	Output folder. Default value: current path

Features

K8sToAzureContainerApp can generate deployment scripts in YAML format from a specified Kubernetes namespace. Currently, it supports migrating the following objects:

• POD:
  • Deployment
  • Pod
  • Horizontal Pod Autoscaler
• Configuration:
  • Secrets
• Storage:
  • Volumes
• Network/Exposure:
  • Ingress
  • Service
  • Endpoint

2. Generate a package:

   Alternatively, you can download the source code and follow these steps for a manual installation:

   pip install -e .
   

Usage

Run K8sToAca using the following command:

K8sToAca --namespace my_name_space --context cluster_context --aca_resource_group target_resource_group --aca_environment target_container_app_environment_name

Replace the placeholders with your actual values.

Deploy to Azure deployment script:

./deployment.sh 

Recomendation

Install Azure CLI using https://learn.microsoft.com/en-us/cli/azure/install-azure-cli

Ensure your Azure CLI and the Azure Container Apps extension are up to date by executing the following commands:

az upgrade
az extension add -n containerapp --upgrade
