provider-upjet-github

Provider GitHub

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

Getting Started

Install the provider by using the following command after changing the image tag to the latest release:

up ctp provider install crossplane-contrib/provider-upjet-github:v0.1.0

Alternatively, you can use declarative installation:

cat <<EOF | kubectl apply -f -
apiVersion: pkg.crossplane.io/v1
kind: Provider
metadata:
  name: provider-upjet-github
spec:
  package: crossplane-contrib/provider-upjet-github:v0.1.0
EOF

You can see the API reference here.

Adding provider config

Add this to configure the provider. Reference on how to configure this can be found at the terraform provider documentation https://registry.terraform.io/providers/integrations/github/latest/docs

Provider config example with personal access token

---
apiVersion: v1
kind: Secret
metadata:
  name: provider-secret
  namespace: upbound-system
type: Opaque
stringData:
  credentials: "{\"token\":\"${GH_TOKEN}\",\"owner\":\"${GH_OWNER}\"}"

---
apiVersion: github.upbound.io/v1beta1
kind: ProviderConfig
metadata:
  name: default
spec:
  credentials:
    source: Secret
    secretRef:
      name: provider-secret
      namespace: upbound-system
      key: credentials

Provider config example with Github application based authentication

Note that the PEM certificate needs to be wrapped in a non-multiline string, with the characters "\n" as newline. See Terraform provider doc for more information.

---
apiVersion: v1
kind: Secret
metadata:
  name: provider-secret
  namespace: upbound-system
type: Opaque
stringData:
  credentials: "{\"app_auth\": [{\"id\": \"${APP_ID}\", \"installation_id\": \"${APP_INSTALLATION_ID}\", \"pem_file\": \"${APP_PEM_FILE}\"}] ,\"owner\":\"${GH_OWNER}\"}"

---
apiVersion: github.upbound.io/v1beta1
kind: ProviderConfig
metadata:
  name: default
spec:
  credentials:
    source: Secret
    secretRef:
      name: provider-secret
      namespace: upbound-system
      key: credentials

Provider config scope

Most operations of the provider happen in the scope of the owner attribute in the credentials JSON structure. This means that the provider will create resources in the context of the given owner. For example, if you want to create a repository in an organization, the owner attribute must point to a GitHub organization. If you want to create a repository in a user account, the owner attribute must point to a GitHub user account.

Note that some resources like OrganizationActionsSecret and OrganizationActionsVariable require the owner attribute to point to the organization as they are not supported at the user level.

Administration of resources on the organization level requires a token with at least admin:org scope.

There are a few endpoints in the GitHub API that operate on the enterprise level and can be used for GitHub customers that have an enterprise account. One such resource is Organization which can be used to provision new organizations on the enterprise level. In this case, the token or app authentication must have at least admin:enterprise scope.
