Kubernetes install

StackState for Kubernetes troubleshooting Self-hosted

Before you start

Extra notes for installing on:

Before you start the installation of StackState:

  • Check the requirements to make sure that your Kubernetes environment fits the setup that you will use (recommended, minimal or non- high availability).

  • 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.io
helm repo update

Install StackState

For environments without internet access, also known as air-gapped environments, first follow these extra instructions.

Also make sure to follow the air-gapped instalaltion instructions whenever those are present for a step.

Create namespace

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 stackstate:

kubectl create namespace stackstate

Generate values.yaml

The values.yaml file is required to deploy StackState with Helm. It contains your StackState license key, StackState Receiver API key and other important information.

Before you continue: Make sure you have the latest version of the Helm charts with helm repo update.

The StackState values.yaml file can be generated by running a separate Helm Chart, the stackstate/stackstate-values chart. A sample command line is:

> helm template \
  --set license='<your license>' \
  --set baseUrl='<stackstate-base-url>' \
  --set pullSecret.username='<your-registry-username>' \
  --set pullSecret.password='<your-registry-password>' \
  sts-values \
  stackstate/stackstate-values > values.yaml

This command will generate a values.yaml file which contains the necessary configuration for installing the StackState Helm Chart.

The StackState administrator passwords will be autogenerated by the above command and are output as comments in the generated values.yaml file. The actual values contain the bcrypt hashes of those passwords so that they're securely stored in the Helm release in the cluster.

The values that can be passed to this chart are:

Store the generated values.yaml file somewhere safe. You can reuse this file for upgrades, which will save time and (more importantly) will ensure that StackState continues to use the same API key. This is desirable as it means Agents and other data providers for StackState won't need to be updated.

Deploy StackState with Helm

The recommended deployment of StackState is a production ready, high availability setup with many services running redundantly. If required, it's also possible to run StackState in a non-redundant setup, where each service has only a single replica. This setup is only recommended for a test environment.

For air-gapped environments follow the instructions for the air-gapped installations.

To deploy StackState in a high availability setup on Kubernetes:

  1. (Optionally) Create a small_values.yaml if you want to deploy a small profile setup. Add the --values small_values.yaml flag to the command below.

  2. Deploy the latest StackState version to the stackstate namespace with the following command:

helm upgrade \
  --install \
  --namespace stackstate \
  --values values.yaml \
stackstate \
stackstate/stackstate-k8s

After the install, the StackState release should be listed in the StackState namespace and all pods should be running:

# Check the release is listed
helm list --namespace stackstate

# Check pods are running
# It may take some time for all pods to be installed or available
kubectl get pods --namespace stackstate

Access the StackState UI

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/<helm-release-name>-stackstate-k8s-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 values.yaml file.
