 # Learn Rollouts
+
+An argocd app of apps that shows how to use rollouts.
+
+## hello-world application
+
+This application consists of a flask application in `/hello-world`, it has 3
+different versions that you can play with tagged `v1`, `v2`, and `v3`.  It will
+respond with a different version number based on the version that is active.
+
+When rolled out with the provided kind cluster it will respond with a different
+header color based on the environment that it is running in.  Since the idea of
+rollouts is zero downtime and to rollout the exact same application both in
+preview and active, the only difference is the url that it is deployed on.
+Based on this url flask will choose the header color.
+
+* active: blue
+* preview: pink
+* local: green
+* unknown: tan
+
+### Docker images
+
+Docker images have been pushed to a public docker hub so they are easily accessible.
+
+<https://hub.docker.com/r/waylonwalker/learn-rollouts/tags>
+
+## Example
+
+Here you can see the application running in all 3 states, active, preview, and local.
+
+![image](https://github.com/WaylonWalker/learn-rollouts/assets/22648375/c0355d25-1e9b-4ef4-8eb5-ed6c6a9e7ce4)
+
+## app of apps
+
+This application is setup as an app of apps.  You will deploy the first application and argocd will manage that app as well as the rest.
+
+![image](https://github.com/WaylonWalker/learn-rollouts/assets/22648375/b5fcdec7-1042-4393-8a9f-9339822a5c6d)
+
+From left to right in the image there is the apps application that contains all
+of the argocd applications, hello-world (the flask application) and argo
+rollouts..
+
+## Setup
+
+I have given instructions for this entire project to run in a
+[kind-cluster](https://kind.sigs.k8s.io/docs/user/quick-start/).  First we are
+going to spin up the kind cluster, install argocd and deploy the app of apps.
+
+First fork the repo, and change the repoURL in `apps/apps.yaml` to your own repoURL.
+
+``` bash
+kind create cluster --name rollout --config kind-config.yaml
+# your first time through you need to add the argocd repo
+helm repo add argo https://argoproj.github.io/argo-helm
+helm repo update
+# install argocd into the cluster
+helm install argo argo/argo-cd --namespace argocd --create-namespace
+# deploy the app of apps
+kubectl apply -f apps/apps.yaml
+```
+
+Now we can access the argocd server by first forwarding the port, getting the
+initial password, then logging in to the `admin` account with that password.
+
+``` bash
+# access the argocd server
+kubectl port-forward service/argo-argocd-server -n argocd 8080:443
+argocd admin initial-password -n argocd
+argocd login localhost:8080
+# you can also access it through a web browser at https://localhost:8080
+# you will have to accept the certificate the first time
+```
+
+Now we can refresh each of our apps with the web browser, or the cli.
+
+``` bash
+argocd app list
+```
+
+```

+```
+
+``` bash
+argocd app sync apps
+argocd app sync rollouts
+argocd app sync hello-world
+```
+
+If you wish to update the argo-server password you can use the following command:
+
+``` bash
+argocd account update-password --account admin --new-password password
+```
+
+## Rollouts
+
+install the rollouts plugin with the instructions from the
+[installation](https://argoproj.github.io/argo-rollouts/installation/#kubectl-plugin-installation)
+page. Then we can access the rollouts dashboard.
+
+``` bash
+kubectl argo rollouts dashboard
+```
+
+![image](https://github.com/WaylonWalker/learn-rollouts/assets/22648375/6030a889-99fa-4d21-95cc-3a630a225af5)
+
+we can also access rollouts through the kubectl plugin.
+
+``` bash
+kubectl argo rollouts get rollout hello-world-bluegreen -n hello-world --watch
+```
+
+## Rolling out a new version
+
+To roll out a new version of the hello-world application we can bump the
+container tag from `v1` to `v2` by updating the deployment.yaml file in the
+`hello-world/deployments` directory. Pushing that change, then we can `argocd app sync`.
+
+<https://github.com/WaylonWalker/learn-rollouts/blob/main/hello-world/deployments/deployment.yaml#L31>
+
+You can now play with changing between different tags, and see how the rollout
+goes.  active is hosted at localhost:30001 and preview at localhost:30002.
