This Project will help on Executing the Chaos and Performance execution leverging open source tools
- You have AWS account access
- You have kubernetes cluster running on using AWS resources
- Kubernetes Cluster installed and setup on your infrastrutre
- You have access to connect to this cluster and execute kubectl in admin mode
The Argo workflow infra consists of the Argo workflow CRDs, Workflow Controller, associated RBAC & Argo CLI. The steps shown below installs argo in the standard cluster-wide mode wherein the workflow controller operates on all namespaces. Ensure that you have the right permission to be able to create the said resources.
If you would like to run argo with a namespace scope, refer to this manifest.
- Create argo namespace
➜ InfraProj git:(master) ✗ kubectl create ns argo - Create the CRDs, workflow controller deployment with associated RBAC
➜ InfraProj git:(master) ✗ kubectl apply -f https://raw.githubusercontent.com/argoproj/argo/stable/manifests/install.yaml - Verify successful creation of argo resources (crds)
InfraProj git:(master) ✗ kubectl get crds | grep argo

- Verify successful creation of argo resources (api-resources)
InfraProj git:(master) ✗ kubectl api-resources | grep argo
clusterworkflowtemplates clusterwftmpl,cwft argoproj.io false ClusterWorkflowTemplate
cronworkflows cwf,cronwf argoproj.io true CronWorkflow
workflows wf argoproj.io true Workflow
workflowtemplates wftmpl argoproj.io true WorkflowTemplate
- Verify successful creation of argo server and workflow
InfraProj git:(master) ✗ kubectl get pods -n argo
NAME READY STATUS RESTARTS AGE
argo-server-78b774dd56-j8xwx 1/1 Running 0 13h
workflow-controller-589bf468d7-bwjtr 1/1 Running 0 13h
- How to access the argo UI Please follow the instruction here
kubectl -n argo port-forward deployment/argo-server 2746:2746
This will serve the user interface on http://localhost:2746
- Install the argo CLI on the harness/test machine (where the kubeconfig is available)
InfraProj git:(master) curl -sLO https://github.com/argoproj/argo/releases/download/v2.8.0/argo-linux-amd64
InfraProj git:(master) chmod +x argo-linux-amd64
InfraProj git:(master) mv ./argo-linux-amd64 /usr/local/bin/argo
InfraProj git:(master) argo version
argo: v2.8.0

- Create a namespace for chaos experiment as app-ns
➜ InfraProj git:(master) ✗ kubectl create ns app-ns
- Install a simple multi-replica stateless nginx deployment with service exposed over nodeport
➜ InfraProj git:(master) ✗ kubectl apply -f nginx_demo.yaml
deployment.apps/nginx-demo-app created
service/nginx-demo-app-svc created
InfraProj git:(master) ✗ kubectl get pods -l app=nginx-demo-app -w

nginx-demo-app-68c58bb7d7-s98wz 1/1 Running 0 94s
- You can access this service over
https://<node-ip>:<nodeport> - If you use ingress you might get ingress endpoint for application
