Crossplane

In this documentation, we will use Alibaba Cloud's RDS (Relational Database Service), and Alibaba Cloud's OSS (Object Storage System) as examples to show how to enable cloud services as part of the application deployment.

These cloud services are provided by Crossplane.

Prepare Crossplane#

Please Refer to [Installation](https://github.com/crossplane/provider-alibaba/releases/tag/v0.5.0) to install Crossplane Alibaba provider v0.5.0.

If you'd like to configure any other Crossplane providers, please refer to Crossplane Select a Getting Started Configuration.

$ kubectl crossplane install provider crossplane/provider-alibaba:v0.5.0
# Note the xxx and yyy here is your own AccessKey and SecretKey to the cloud resources.
$ kubectl create secret generic alibaba-account-creds -n crossplane-system --from-literal=accessKeyId=xxx --from-literal=accessKeySecret=yyy
$ kubectl apply -f provider.yaml

provider.yaml is as below.
