An small node-js app triggering a small Azure-Devops pipeline to deploy multiple HELM-Charts into any Kubernetes cluster.
In this example it is deploying to an AWS-EKS and an Azure-AKS cluster at the same time. Dragging a HELM-Chart from one cloud to another.
This is done by deploying Azure-Devops agents in the clusters itself. In 4 namespaces there are 4 Azure-Devops agents running.
Each agent is running in another agent-pool allowing for choice where to deploy.
Try this yourself (you can also run this on minikube with 4 namespaces)
1) Azuredevops
-Create an Azure-devops organization, add a project and within the project add a repo
-Add all the files from the folder azure-devops-charts-repo to that repo
-Create a pipeline. The code for the pipeline in is the same folder (azure-pipelines.yml)
-Create 3 variables in the pipeline: helmaction, helmchart and mypool
-Note the pipelineid number in the url link (see image below).
-Create 4 agent pools (eks-dev, eks-tst, aks-dev and aks-tst)
-Create an access token
- Kubernetes
-Create 4 namespaces either in 2 K8s clusters (AWS, EKS, GKE) or in minikube or wherever. See the K8s-yamls folder
-Extend the rights of the default account so that that account can deploy resources in the namespaces (rights.yaml)
-Deploy the az-devops-agent yamls but make sure the values there are filled in:
The azure-devops-agent docker image has Helm3, Kubectl and is build on Ubuntu 18.04 (latest).
Optionally build your own dockerfile for azdevops agent (see ...docker-image folder)
3)
The frontend app
On the environment where you run the app set these env vars:
API_PROJECT = enter azure devops projectname
API_PIPELINEID = the pipeline id you noted at step 1
API_TOKEN = enter azure devops API token that has rights to trigger pipeline
API_URL = HTTPS://dev.azure.com/*yourazdevopsorg*
TOKEN = a password/token used in the app that is checked when triggering pipeline. Just set this to 'something' and enter the same in the gui
Install npm / nodejs
from the dragdrop-app folder open a command prompt:
npm i
npm start
then open a browser and go to localhost:3000 Make sure you enter the TOKEN here ('something') before drag and dropping:
That should be it. Let me know if there is an issue
