Kubernetes install
StackState for Kubernetes troubleshooting Self-hosted
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).
- Add the StackState helm repository to the local helm client:
helm repo add stackstate https://helm.stackstate.io
helm repo update
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.
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
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 chart with
helm repo update.The
generate_values.sh script in the installation directory of the Helm chart will guide you through generating a values.yaml file that can be used to deploy StackState. 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../generate_values.sh
- Non-interactive mode: Run the script with the flag
-nto pass configuration on the command line, this is useful for scripting../generate_values.sh -n <configuration items>
The script requires the following configuration items:
Configuration | Flag | Description |
|---|---|---|
Base URL | -b | The <STACKSTATE_BASE_URL>. The external URL for StackState that users and agents will use to connect. For example https://stackstate.internal. If you haven't decided on an Ingress configuration yet, use http://localhost:8080. This can be updated later in the generated file. |
Username and password** | -u -p | The username and password used by StackState to pull images from quay.io/stackstate repositories. For air-gapped environments these need to be the username and password for the local docker registry. |
License key | -l | The StackState license key. |
Admin API password | -a | 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. You can omit this from the command line, the script will prompt for it. |
Default password | -d | The password for the default user ( admin) to access StackState's UI. You can omit this from the command line, the script will prompt for it. |
Kubernetes cluster name | -k | StackState will use this name to identify the cluster. In non-interactive mode, specifying -k will both enable automatic Kubernetes support and set the cluster name. In interactive mode, you will first be asked if you want to automatically install the Kubernetes StackPack. |
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.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.
High availability setup
Non-high availability setup
Air-gapped, high availability setup
Air-gapped, non-high availability setup
To deploy StackState in a high availability setup on Kubernetes:
- 1.Before you deploy:
- 2.Deploy the latest StackState version to the
stackstatenamespace with the following command:
helm upgrade \
--install \
--namespace stackstate \
--values values.yaml \
stackstate \
stackstate/stackstate-k8s
To deploy StackState in a non-high availability setup on Kubernetes:
- 1.
- 2.Deploy the latest StackState version to the
stackstatenamespace with the following command:
helm upgrade \
--install \
--namespace stackstate \
--values values.yaml \
--values nonha_values.yaml \
stackstate \
stackstate/stackstate-k8s
To deploy StackState in a air-gapped, high availability setup on Kubernetes:
- 2.Deploy the latest StackState version to the
stackstatenamespace with the following command:
helm upgrade \
--install \
--namespace stackstate \
--values local-docker-registry.yaml \
--values values.yaml \
stackstate \
stackstate/stackstate-k8s
To deploy StackState in a air-gapped, non-high availability setup on Kubernetes:
- 2.Deploy the latest StackState version to the
stackstatenamespace with the following command:
helm upgrade \
--install \
--namespace stackstate \
--values local-docker-registry.yaml \
--values values.yaml \
--values nonha_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
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.Next steps are
