Upgrade KOTS
Do not roll back or downgrade without consulting our support team first. Certain scenarios may necessitate restoring the database from a pre-upgrade backup due to the complexity of reversing some database migrations.
Preflight checks are critical for a successful installation. The following rules apply:
- ❌ Preflight Check Failures: If preflight checks fail, the upgrade must not continue until the targeted environment meets all requirements. Please reach out to our support team.
- ⚠️ Preflight Check Warnings: If preflight checks return warnings, the installation can proceed, but it is recommended that you address these warnings to comply with our recommendations.
Upgrading the GitGuardian application
Prior to upgrading, ensure you back up your PostgreSQL database. For detailed instructions, refer to the Backup page.
The GitGuardian application can be updated through the KOTS Admin Console in the "Version History" tab. First, you need to check for updates. This can be done manually or automatically. Then, you can deploy a newer version by clicking the "Deploy" button.
On Embedded clusters V2, updating the application through the KOTS Admin Console also upgrades the Kubernetes cluster if needed.
You can find more information on the KOTS documentation.
During upgrades, workers are stopped but new commits are still queued and will be processed after the upgrade. Upgrades do not stop the dashboard, but they introduce a temporary delay in message processing and alerting. We advise running upgrades during a low-traffic period.
Upgrading the GitGuardian application in Airgap
To upgrade the KOTS admin interface, follow the installation instructions: install the latest version of the KOTS plugin of your machine, download the latest KOTS bundle and upload these images to your registry. Then, instead of running the installation command, you will need to upgrade the KOTS application running in the cluster:
kubectl kots admin-console upgrade --namespace <namespace>
If needed, specify the Kubernetes namespace with --namespace (default namespace is used if not specified).
To upgrade the GitGuardian application, first download the latest application bundle on the download portal. Then go to your KOTS Admin Console on the "Version History", and click on "Upload new version". Upload the bundle and deploy it.
Required versions
KOTS Admin Console will show some versions as "Required".
If you have several versions to upgrade, you'll have to upgrade to each required version between your current version and your target version.
After each deployment, you should wait for the application to be fully upgraded. To that extent, you can monitor pods' status and wait for all pods to be live and all jobs to be completed.
watch kubetcl get po -n <namespace>
The application is restarted when all pods are in the running status:
Every 2.0s: kubectl get po -n default gitguardian-example: Thu Jul 4 06:11:24 2024

We have set a 30-days TTL (Time To Live) for pre-deploy and post-deploy jobs to allow for log retrieval if needed. It is recommended not to delete these pods, as they can be useful for troubleshooting.
Upgrading KOTS
Please remember that regular upgrades of KOTS are necessary. GitGuardian releases are thoroughly tested with the latest KOTS release. To ensure full functionality and compatibility, some features may not perform as expected on older versions of KOTS. We strongly recommend staying updated with the most recent releases.
To check the KOTS plugin version, run the following command:
kubectl kots version
If there is an update available, follow the instructions and run this command:
curl https://kots.io/install | bash
For existing cluster, you will need to upgrade the KOTS application running in the cluster:
kubectl kots admin-console upgrade -n <namespace>
For Embedded cluster installations (instances installed in 2025 or after), KOTS is upgraded automatically with the GitGuardian application.
For Embedded cluster legacy (kURL) installations (instances installed in 2024 or before), simply re-run the same installation command as outlined in the installation guide.
⚠️ During the upgrade you will be prompted (possibly more than once) with a Y/N question to drain the node and apply the upgrade. You should respond with Y to continue. Because this step deletes all pods on the node, there will be some brief downtime while the upgrade happens and you should plan accordingly.
🌐 If you are using an HTTP proxy, ensure that you follow the instructions.
For further instructions on upgrading KOTS, refer to the Replicated documentation.
In some cases, the preflight checks may not detect the KOTS admin version change correctly, leading to failures even when using the required minimum KOTS version. To address this issue, follow these steps:
- Navigate to the KOTS Admin Console.
- Go to Config > Advanced Options.
- Adjust the number of email worker replicas (for example, from 2 to 1).
- Deploy your configuration change.
- Click the Check for update link.
- Run the preflight checks again.
- Once the preflight checks are completed, revert the change by restoring the number of email worker replicas to its original value.
Upgrading Kubernetes on Embedded Cluster legacy (kURL) (instances installed in 2024 or before)
To upgrade your Kubernetes version for the embedded cluster, follow these steps:
- Simply re-run the same installation command as outlined in the installation guide.
⚠️ During the upgrade you will be prompted (possibly more than once) with a Y/N question to drain the node and apply the upgrade. You should respond with Y to continue. Because this step deletes all pods on the node, there will be some brief downtime while the upgrade happens and you should plan accordingly.
🌐 If you are using an HTTP proxy, ensure that you follow the instructions.
- To verify the Kubernetes version, execute the following command:
kubectl version
