MetroStar Onyx - cert-manager plugin for Nebari platform
Project description
Nebari Plugin Cert-Manager Chart
Overview
This plugin integrates cert-manager into the Nebari platform, allowing X.509 certificate management within Nebari. Utilizing Python, Terraform, Kubernetes, and Helm charts, the plugin provides a configurable deployment.
Design and Architecture
The plugin follows a modular design, leveraging Terraform to define the deployment of cert-manager within a Kubernetes cluster. Key components include:
- Terraform Configuration: Defines variables, outputs, and resources for deployment, including Helm release and Kubernetes secrets.
- Helm Chart Integration: Deploys cert-manager as a Helm chart within the specified Kubernetes namespace.
Installation Instructions
pip install nebari-plugin-cert-manager-chart
Usage Instructions
Configurations: Various configurations are available, including email, certificate, issuer, solver, and namespace settings.
Configuration Details
Environment Variable
The below environment variable must be present when deploying Nebari platform to create cloudflare-api Secret for Issuer to retrieve if using Cloudflare solver.
#### cloudflare-apikey
# have to get the client secret from cloudflare manually
export CLOUDFLARE_TOKEN="!!!GetThisFromCloudflareConsole!!!"
Public
Configuration of the cert-manager plugin is controlled through the cert_manager
section of the nebari-config.yaml
for the environment.
cert_manager:
# helm release name and namespace - default default (nebari global namespace)
namespace: cert-manager
# email address to be associated with the ACME account
email: sblair@metrostar.com
# API to manage DNS01 ACME challenge records - default cloudflare
solver: cloudflare
# whether to use ACME server's staging or production endpoint - default false
staging: false
# list of certificate resources to be created
certificates:
# name of certificate
- name: metrostar-certificate
# issuer responsible for issuing the certificate
issuer: letsencrypt
# list of issuers representing certificate issuing authority
issuers:
# name of issuer
- name: letsencrypt
# type of issuer
type: letsencrypt
# ID of the CA key that the External Account is bound to, if any - leave blank if none
keyId: ""
# symmetric MAC key of the External Account Binding, if any - leave blank if none
existingSecret: ""
# helm chart values overrides
values: {}
Internal
The following configuration values apply to the internally managed terraform module and are indirectly controlled through related values in nebari-config.yaml
.

Testing Overview
The plugin includes unit tests to validate its core functionalities:
- Constructor Test: Verifies the default priority.
- Input Variables Test: Validates namespaces, solver type, staging flag.
- Default Namespace Test: Tests the default namespace configuration.
