Before you start the installation of StackState:
Check that your Kubernetes environment meets the requirements
Check that you have the required permissions
Request access credentials to pull the StackState Docker images from StackState support.
Add the StackState helm repository to the local helm client:
helm repo add stackstate https://helm.stackstate.iohelm repo update
Start by creating the namespace where you want to install StackState and deploy the secret in that namespace. In our walkthrough we will use the namespace
kubectl create namespace stackstate
values.yaml is required to deploy StackState with Helm. It contains your StackState license key, API key and other important information. The
generate_values.sh script in the installation directory of the Helm chart will guide you through generating the file.
You can run the
generate_values.sh script in two ways:
Interactive mode: When the script is run without any arguments, it will guide you through the required configuration items.
Non-interactive mode: Run the script with the flag
-n to pass configuration on the command line, this is useful for scripting.
./generate_values.sh -n <configuration items>
The script requires the following configuration items:
The external URL for StackState that users and agents will use to connect. For example
Username and password**
The username and password used by StackState to pull images from quay.io/stackstate repositories.
The StackState license key.
Admin API password
The password for the admin API. Note that this API contains system maintenance functionality and should only be accessible by the maintainers of the StackState installation. This can be omitted from the command line, the script will prompt for it.
The password for the default user (
Kubernetes cluster name
StackState will use this name to identify the cluster. In non-interactive mode, specifying
The generated file is suitable for a production setup (i.e. redundant storage services). It is also possible to create smaller deployments for test setups, see development setup.
Use the generated
values.yaml file to deploy the latest StackState version to the
stackstate namespace with the following command:
helm upgrade \--install \--namespace stackstate \--values values.yaml \stackstate \stackstate/stackstate
After the install, the StackState release should be listed in the StackState namespace and all pods should be running:
# Check the release is listedhelm list --namespace stackstate# Check pods are running# It may take some time for all pods to be installed or availablekubectl get pods --namespace stackstate
After StackState has been deployed you can check if all pods are up and running:
kubectl get pods --namespace stackstate
When all pods are up, you can enable a port-forward:
kubectl port-forward service/stackstate-router 8080:8080 --namespace stackstate
StackState will now be available in your browser at
https://localhost:8080. Log in with the username
admin and the default password provided in the

StackState has built-in support for Kubernetes by means of the Kubernetes StackPack. To get started quickly, the StackState installation can automate installation of this StackPack and the required agent for the cluster that StackState itself will be installed on. This is not required and can always be done later from the StackPacks page of the StackState UI for StackState's cluster or any other Kuberenetes cluster.
The only required information is a name for the Kubernetes cluster that will distinguish it from the other Kubernetes clusters monitored by StackState. A good choice usually is the same name that is used in the kube context configuration. This will then automatically install the StackPack and install a Daemonset for the agent and a deployment for the so called cluster agent. For the full details, please read the Kubernetes StackPack page.
