Getting started with kOps on Scaleway
kOps is a tool that helps you set up and manage Kubernetes clusters for production use. It is like a version of
kubectl specifically designed for managing clusters.
With kOps, you can easily create, upgrade, and maintain highly available clusters. The tool also takes care of setting up the required cloud infrastructure.
Scaleway support on kOps is currently in alpha, which means that it is in the early stages of development and subject to change. Use it with caution.
You may need certain IAM permissions to carry out some actions described on this page. This means:
- you are the Owner of the Scaleway Organization in which the actions will be carried out, or
- you are an IAM user of the Organization, with a policy granting you the necessary permission sets
- You have an account and are logged into the Scaleway console
- You have configured your SSH Key
- You have installed kOps version >= 1.26 on your local computer
- You have installed
kubectlon your local computer
- You have created an S3 bucket and have its credentials
Configuring environment variables
Before working on the tutorial, it is important to set the following environment variables on your local computer.
export SCW_ACCESS_KEY="my-access-key"export SCW_SECRET_KEY="my-secret-key"export SCW_DEFAULT_PROJECT_ID="my-project-id"# Configure the bucket name to store kops stateexport KOPS_STATE_STORE=scw://<bucket-name> # where <bucket-name> is the name of the bucket you set earlier# Scaleway Object Storage is S3 compatible so we just override some S3 configurations to talk to our bucketexport S3_REGION=fr-par # or another scaleway region providing Object Storageexport S3_ENDPOINT=s3.$S3_REGION.scw.cloud # define provider endpointexport S3_ACCESS_KEY_ID="my-access-key" # where <my-access-key> is the S3 API Access Key for your bucketexport S3_SECRET_ACCESS_KEY="my-secret-key" # where <my-secret-key> is the S3 API Secret Key for your bucket# this is required since Scaleway support is currently in alpha so it is feature gatedexport KOPS_FEATURE_FLAGS="Scaleway"
Creating a single master cluster using kOps
Currently you can only create a kOps cluster in a single Availability Zone (
- Create a cluster in the
fr-par-1Availability Zone, by running the following command:kops create cluster --cloud=scaleway --name=mycluster.k8s.local --zones=fr-par-1 --yesNote:
The default cluster uses Ubuntu images on DEV1-M machines with
ciliumas Container Network Interface.
Editing a cluster using kOps
Update a cluster
- Run the following command to update your cluster using kOps:
kops update cluster mycluster.k8s.local --yes
Delete a cluster
- Run the following command to delete your cluster using kOps:
kops delete cluster mycluster.k8s.local --yes
Now that you have a working
kops cluster, read through the recommendations for production setups guide to learn more about how to configure kOps for production workloads.
For more information about kOps, refer to the official kOps documentation.
