gitops-platform

The repo used to build the platform

Quick start

Set AWS variables (This example uses temporary creds)

export AWS_ACCESS_KEY_ID="XXXXXXXXXX"
export AWS_SECRET_ACCESS_KEY="YYYYYYYYYYY"
export AWS_SESSION_TOKEN="ZZZZZZZZZZ"

Install software

make install

#
# Update path to include installed tools
#
export PATH=$PATH:$HOME/.arkade/bin

Create EKS cluster

make

NOTE:

See Issue #2 for work-around to known startup bug

kubectl delete applicationset argo-projects -n argocd

ArgoCD

Start a proxy to expose the UI

kubectl port-forward svc/argocd-server -n argocd 8080:443

Retrieve password

PASS=$(kubectl -n argocd get secret argocd-initial-admin-secret -ogo-template='{{.data.password | base64decode}}')
echo $PASS

http://localhost:8080

or login with CLI

argocd login localhost:8080 --insecure --username=admin --password=$PASS

Adding a new cluster

Start a second cluster

eksctl create cluster -f bootstrap/eks/fargate-cluster2.yaml

Add it to ArgoCD

argocd cluster add <context name> --name cluster2

Wait for it to synchronize

$ argocd cluster list
SERVER                                                                    NAME        VERSION  STATUS      MESSAGE

Note how applications are automatically deployed to this cluster

$ argocd app list

Adding workloads

Workloads are managed in a separate repository

https://github.com/myspotontheweb/gitops-workloads

Deploy the workloads using the argocd command-line:

#
# Create bootstrap app
#
argocd app create workloads-bootstrap \
  --repo https://github.com/myspotontheweb/gitops-workloads.git \
  --path projects \
  --project default \
  --dest-server https://kubernetes.default.svc \
  --dest-namespace argocd

#
# Set sync policy
#
argocd app set workloads-bootstrap --sync-policy automated --self-heal
