Installing Crossplane with Yandex Cloud support

Crossplane is a freeware add-on to Kubernetes that enables platform development teams to build infrastructure for multiple vendors and produce higher-level service APIs for application development teams.

Getting startedGetting started

1. If you do not have the Yandex Cloud command line interface yet, install and initialize it.

   The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

2. Create a service account with the admin role. It is required for Crossplane to run.

3. Create a service account key and save it to the file:

   yc iam key create --service-account-name <service_account_name> --output key.json
   

4. Make sure that the security groups for the Managed Service for Kubernetes cluster and its node groups are configured correctly. If any rule is missing, add it.

   Warning

   The configuration of security groups determines the performance and availability of the cluster and the services and applications running in it.

2. Install kubectl and configure it to work with the created cluster.

3. To install a Helm chart with Crossplane, run the following command:

   helm pull oci://cr.yandex/yc-marketplace/yandex-cloud/crossplane/crossplane \
     --version 1.15.0 \
     --untar && \
   helm install \
     --namespace <namespace> \
     --create-namespace \
     --set-file providerJetYC.creds=key.json \
     crossplane ./crossplane/
   

   Note

   If you are using a Helm version below 3.8.0, append the export HELM_EXPERIMENTAL_OCI=1 && \ string to the command to enable Open Container Initiative (OCI) support in the Helm client.
