Why Wunder-Wander Gitops?

TBD

How to use

• Deploy the Wunder-Wander Gitops controller and CRD:

$ kubectl apply -f "https://raw.githubusercontent.com/foldingbeauty/wunder-wander/$(curl -s https://raw.githubusercontent.com/foldingbeauty/wunder-wander/master/release.txt)/deployment/deployment.yaml"

• Check if everything is ready to go:

$ kubectl get all -n wunderwander-gitops

NAME                                              READY   STATUS    RESTARTS   AGE
pod/gitops-operator-controller-64757768b5-g82jr   1/1     Running   0          22s
pod/gitops-operator-ui-6b978c66bf-5jkcg           1/1     Running   1          22s

NAME                                         DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/gitops-operator-controller   1         1         1            1           24s
deployment.apps/gitops-operator-ui           1         1         1            1           24s

NAME                                                    DESIRED   CURRENT   READY   AGE
replicaset.apps/gitops-operator-controller-64757768b5   1         1         1       24s
replicaset.apps/gitops-operator-ui-6b978c66bf           1         1         1       24s

• Get the SSH Public key and add the key to your Git repository

$ kubectl get secret/ssh-keys -n wunderwander-gitops -o jsonpath="{.data.public_key}"| base64 --decode ; echo

ssh-rsa ... ==

• Create a Gitops Resource with your Git repository

example-gitops-crd.yaml

apiVersion: "io.wunderwander/v1"
kind: GitOp
metadata:
  # the name of the CRD + branch name is the name of the namespace
  name: test-app
  namespace: wunderwander-gitops
spec:
  repo: git@github.com:foldingbeauty/wunderwander-test-app.git
  branch: master

$ kubectl apply -f example-gitops-crd.yaml

When a GitOps resource is deployed, the Wunder-Wander controller will checkout the Git repository and start deploying the contents.

• Check the deployment

$ kubectl get all -n wunderwander-gitops

• Check if you the GitOps worker can connect to your Git repository

$ kubectl logs deploy/test-app -n wunderwander-gitops
