If you need to pull Thoras container images from your own private registry instead of the public Thoras registry, you can override the default registry location using the $.Values.imageCredentials.registry value.

​
Prerequisites

  1. Access to download Thoras container images (email support@thoras.ai for assistance)
  2. A private container registry accessible from your Kubernetes cluster
  3. Container images pushed to your private registry

​
Configuration

Set the private registry hostname value in your Helm values.yaml:

​
Copying Multi-Platform Images

Thoras container images are built for multiple platforms (linux/amd64 and linux/arm64) to support multiple CPU architectures. When copying images from the Thoras registry to your private registry, it’s a good idea to preserve the multi-platform manifest to ensure compatibility across different CPU architectures.

​
Generate a list of images to copy

The list will include Thoras images (services, thoras-dashboard-v2, thoras-forecast, nginx, timescaledb) as well as oauth2-proxy and httpd (the dashboard auth sidecar and its init container) and kube-webhook-certgen (webhook TLS, unless you use cert-manager). All are hosted on the Thoras registry, so air-gapped installs only need to mirror from the Thoras registry. No separate upstream mirror step is needed.
If you deploy with helm template rather than helm install, set featureFlags.enableLegacySecretSeeding: false in your values (see Legacy secret seeding) and consider cert-manager for webhook TLS so no Helm hook Jobs are involved.

​
Using Docker Buildx

The recommended approach is to use docker buildx imagetools create, which preserves the multi-platform manifest. Substitute <VERSION> with the tag that helm template shows for the release you’re deploying:

​
Verifying Multi-Platform Support

After copying, verify that both platforms are available:
You should see both linux/amd64 and linux/arm64 in the output.
