Get Started with GitOps Run
GitOps Run supports two different modes of operation - directly on a cluster or as sandboxed sessions. The sandboxed sessions are intended for shared environments where multiple users are running their own sessions, whereas the direct mode is intended for a local cluster.
In this tutorial we are going to use 'direct mode' to run GitOps on a local cluster.
- Install the GitOps CLI. See the installation
- This guide uses kubectl for demonstrations, but it is not required to use GitOps Run
- The Flux CLI is the quickest way to generate resource definitions, but the files can also be created manually
Create a local Kubernetes cluster
To get started with GitOps Run, you need a Kubernetes cluster. There are many tools to set up a local cluster for test and development purposes.
This tutorial assumes you have full control of your cluster - we
recommend a local cluster, but you can also use a remote cluster where
you have full
- docker desktop
Install kind and run
kind create cluster
Install k3d and run
k3d cluster create mycluster
Install minikube and run
Install Docker Desktop and enable Kubernetes. Then run
kubectl config set-context docker-desktop
GitOps Run works on any Kubernetes platform, but to avoid accidents you have to explicitly white-list the context name.
First, find the name of the context where you want to run
gitops beta run - in this example, there's a cluster with the name "dev":
$ kubectl config get-contexts
CURRENT NAME CLUSTER AUTHINFO NAMESPACE
* dev dev dev
Then, for any
gitops beta run command in this guide, you'll have to add the flag
Before you continue, make sure
kubectl get nodes returns a node which is
Create a GitOps repository
You need to set up a Git repository to put your GitOps manifests in. Any Git repository will do, for example create a new github repository and clone that.
You may alternatively fork an existing repository, as we have done for this guide. Head
to podinfo and create a fork with the
Set up GitOps Run
To start GitOps Run, clone your newly created repository or fork and change into it.
We will run the command with
--no-session as it's a single user
cluster which we want to use in direct mode. The port-forward points
podinfo pod we will create later on.
export GITHUB_USER=<your github username>
# you can ignore these two commands if you already created and cloned your repository
git clone firstname.lastname@example.org:$GITHUB_USER/podinfo-gitops-run.git
gitops beta run ./podinfo --no-session --port-forward namespace=dev,resource=svc/dev-podinfo,port=9898:9898
You will now be asked if you want to install Flux and the GitOps
yes and set a password.
If you do not set a password, you won't be able to login to the GitOps UI 😱.
Shortly after you should be able to open the dashboard.
The username is
admin and the password will be the one you set above.
In your dashboard you will be able to see what is in your cluster, including the resources that GitOps Run is operating.
Start modifying your deploment
In your local GitOps repo, you will see that GitOps Run has created a new
podinfo. Inside there is a single, mostly empty,
To create the automation for the
podinfo app, we first have to add the resources to
run it - we'll create a new
references the Helm repository where the manifests are stored, and a
HelmRelease that references the chart and version. We can use the
flux CLI to generate the resource definition, or we can just create
the yaml files ourselves.
cat <<EOF > ./podinfo/namespace.yaml
flux create source helm podinfo --url=https://stefanprodan.github.io/podinfo --namespace=dev --export > ./podinfo/podinfo-source.yaml
flux create helmrelease podinfo --source=HelmRepository/podinfo --chart=podinfo --export --namespace=dev --target-namespace=dev > ./podinfo/podinfo-helmrelease.yaml
You should see three files now exist in your
Save the contents of the following files to the
The only remaining step is to import these files in the auto-generated
kustomization.yaml. Open it up, and you should see the following:
resources:  # 👋 Start adding the resources you want to sync here
Change the last line so it instead looks like the following:
GitOps Run should now automatically upload these manifests and install them. The dashboard should show you how the resources are being reconciled, and when they're Ready you will be able to see podinfo here.
Update your app
Now that GitOps Run is continuously watching and reconciling your local files onto your cluster, we can start modifying the resources.
We're going to be modifying the
podinfo we set up in the previous
step. Open the current podinfo and pay
attention to the background color.
Now, open your HelmRelease file and add the values at the bottom, as indicated:
When you hit save, you'll see GitOps Run upload new files, and once
it's reconciled the
podinfo background will have been changed to a bright red.
Next steps: GitOps Mode
Now that we've used this interactive environment to set up the resources we want, we can switch over to full GitOps mode, where Flux is permanently pulling from your remote Git repository.
ctrl-c to stop GitOps Run. It will ask you whether you want to bootstrap
your cluster into full GitOps mode. If you answer yes, it
will take you through a wizard to help you set this up. You'll need information
such as the remote repository, the branch name, etc.
When you hit submit, it will set up the repository and branch, add Flux manifests, as well as the files you were just working on. From this point on, you can make persistent changes by pushing them to this repository.
