❗ This Helm Chart is deprecated!

A Helm chart for LangKit container deployment

⚠️ Review the documentation on using WhyLab's Helm charts

Prerequisites

NOTE: Change the --namespace value to the target Namespace to deploy the service.

Credentials

• Create a WhyLabs API Key which must be stored in a whylabs-api-key Kubernetes secret, described below.

kubectl create secret generic whylabs-api-key \
  --namespace=<namespace> \
  --from-literal=WHYLABS_API_KEY=<whylabs-api-key>

• Generate a random value for the langkit-api-secret Kubernetes secret, also described below. This secret is required to call the container API endpoint.

kubectl create secret generic langkit-api-secret \
  --namespace=<namespace> \
  --from-literal=CONTAINER_PASSWORD=<langkit-api-secret>

• Create a secret with a WhyLabs provided GitLab token to pull the LangKit image

kubectl create secret docker-registry langkit-gitlab-registry-secret \
  --docker-server="registry.gitlab.com" \
  --docker-username="project_55361491_bot_5a6afbd67224dd1583ccd6c7987354c3" \
  --docker-password="<token>" \
  --docker-email="project_55361491_bot_5a6afbd67224dd1583ccd6c7987354c3@noreply.gitlab.com" \
  --namespace=<namespace>

LangKit Configuration

No LangKit configurations are required out of the box. However, for further customizations, review the langkit-container-examples repository for more details.

Hardware Requirements

🚀 For best performance, use Intel processors and ≥ 6 GiB memory per replica.
