Crossplane Provider OpenStack

provider-openstack is a Crossplane provider that is built using Upjet code generation tools and exposes XRM-conformant managed resources for the OpenStack API.

Getting Started

Installation

You can use declarative installation to install the provider:

apiVersion: pkg.crossplane.io/v1
kind: Provider
metadata:
  name: provider-openstack
spec:
  package: xpkg.crossplane.io/crossplane-contrib/provider-openstack:vX.Y.Z

You can see the API reference here.

Configuration

---
# Providerconfig that referers to the secret
apiVersion: openstack.crossplane.io/v1beta1
kind: ProviderConfig
metadata:
  name: provider-openstack-config
spec:
  credentials:
    source: Secret
    secretRef:
      key: config
      name: provider-openstack-config
      namespace: crossplane

---
# Secret that stores credentials and other configuration
apiVersion: v1
kind: Secret
metadata:
  name: provider-openstack-config
  namespace: crossplane
type: Opaque
data:
  config: <see below>

The secret key must contain a json dictionary that provides the authentication data. You can create the secret via this command:

kubectl create secret generic provider-openstack-config --from-file=config=config.json --namespace crossplane

// config.json
{
  "auth_url": "https://auth.openstack.example/",
  "application_credential_id": "123456789",
  "application_credential_secret": "secret-key"
}

Check Terraform OpenStack provider docs to see available configuration settings. Currently not all options of the upstream provider are supported. Check client code to see if your option is supported. If something is missing, please open a new issue.

Deployment Customization

You can use a DeploymentRuntimeConfig to provide custom arguments or otherwise modify the provider deployment

Available command line arguments can be found here

---
# Create a DeploymentRuntimeConfig to customize the provider deployment
apiVersion: pkg.crossplane.io/v1beta1
kind: DeploymentRuntimeConfig
metadata:
  name: provider-openstack
spec:
  deploymentTemplate:
    spec:
      # Control replica count to temporary disable deployment. Do not scale more than 1 replica.
      replicas: 1
      selector: {}
      template:
        metadata:
          annotations:
            # Add annotations, e.g. to enable metrics scraping
            prometheus.io/path: /metrics
            prometheus.io/port: "8080"
            prometheus.io/scrape: "true"
        spec:
          containers:
          - args:
            # Add command line arguments, e.g. to enable management policies
            - --enable-management-policies
            name: package-runtime

---
# Add this to your provider resource to reference the DeploymentRuntimeConfig
spec:
  runtimeConfigRef:
    apiVersion: pkg.crossplane.io/v1beta1
    kind: DeploymentRuntimeConfig
    name: provider-openstack

Developing

Install the required submodules to build and run:

make submodules

Apply the Current CRDs and a providerConfig:

kubectl apply -f package/crds
kubectl apply -f examples/providerconfig/providerconfig.yaml

Run against a Kubernetes cluster: (make sure to apply CRDs and providerConfig)

make run

Run a testbuild with linting:

make reviewable

Build binary:

make build

Release a new version (Maintainer)

• Update Changelog (Add new Version & Date)
• Create or merge to existing release branch (release-v(major).(minor))
