Helm must be installed to use the charts. Please refer to Helm's documentation to get started.
Once Helm has been set up correctly, add the repo as follows:
helm repo add terrakube-repo https://AzBuilder.github.io/terrakube-helm-chart
If you had already added this repo earlier, run helm repo update to retrieve
the latest versions of the packages. You can then run helm search repo terrakube-repo to see the charts.
To install the chart:
kubectl create namespace terrakube
helm install terrakube terrakube-repo/terrakube -n terrakube
To uninstall the chart:
helm delete terrakube -n terrrakube
To quickly test Terrakube in Minikube please follow this
To install Terrakube in a Kubernetes cluster you will need the following:
- Dex connector with support for the groups claim. For example:
- Azure Storage Account, Amazon S3 bucket, GCP Bucket and MinIO(Using AWS Endpoint)
- Supported database:
- SQL Azure
- PostgreSQL
- Mysql
- Create a YAML file with all the require parameters.
Please make sure to have a kubernetes setup with some ingress setup completed for example Nginx Ingress, but any other kubernetes ingress should work.
To handle authentication we use DEX to support different providers using connectors, you can use any connectors as long it supports the groups scope. For example you can use the following connectors:
- LDAP
- GitHub
- SAML 2.0
- Gitlab
- OpenID Connect
- Microsoft
- OpenShift
- Etc.
DEX authentication is only supported from terrakube 2.6.0 and helm chart version 2.0.0 the helm chart values are not backward compatibly with lower version.
Once we have decided which connectors we would like to us we can create Dex configuation. The following in an example of Dex configuration using Azure Active Directory, Google Cloud Identit, Github and Gitlab to handle authentication and groups:
config:

In order to use Terrakube you will have to define the one administrator group, for example:
- TERRAKUBE_ADMIN
Members of these groups are the only users inside terrakube that can create organizations and handle team access
Example:
security:
adminGroup: "TERRAKUBE_ADMIN"
patSecret: "<<CHANGE_THIS>>" # Sample Key 32 characters z6QHX!y@Nep2QDT!53vgH43^PjRXyC3X
internalSecret: "<<CHANGE_THIS>>" # Sample Key 32 characters Kb^8cMerPNZV6hS!9!kcD*KuUPUBa^B3
The patSecret and internalSecret should be a 32 character base64 compatible string.
For Google Cloud Identity groups name will be like "[email protected]", For Github Authentication will be like "organizationName:teamName"
Terrakube require an Azure Storage account to save the state/output for the jobs and to save the terraform modules when using terraform CLI and it require the following containers:
- registry (blob)
- tfstate (private)
- tfoutput (private)
To create the Azure storage account you can use the following terraform module.
Terrakube require an Aws S3 to save the state/output for the jobs and to save the terraform modules when using terraform CLI, it could be a private bucket.
To create the Aws S3 you can use the following terraform module (Work in Progress).
Terrakube require an Storage bucket to save the state/output for the jobs and to save the terraform modules when using terraform CLI.
To create the Gcp Storage you can use the following terraform module (Work in Progress).
Terrakube require an Storage bucket to save the state/output for the jobs and to save the terraform modules when using terraform CLI.
To create the MinIO Storage you can use the following terraform module (Work in Progress).
Once you have completed the above steps you can complete the file values.yaml to deploy the helm chart, you can check the example folder:
- Google Identity Authentication
- Azure Authentication
- Github Authentication
- Amazon AWS Cognito

Now you have all the information to deploy Terrakube, you can use the following example:
Clone the helm chart repository and fill the values.yaml file
git clone https://github.com/AzBuilder/terrakube-helm-chart.gitCreate the kubernetes namespace:
kubectl create namespace terrakubeTest the helm chart before installing:
helm install --debug --dry-run --values ./values.yaml terrakube ./terrakube-helm-chart/charts/terrakube/ -n terrakubeRunning the helm chart.
helm install --debug --values ./values.yaml terrakube ./terrakube-helm-chart/charts/terrakube/ -n terrakubeAfter installing you should be able to view the app using ui domain inside the values.yaml.
