AWS (EKS)
Before creating the provider, please note that any clusters provisioned via provisioning need to be deleted from Cocktail, not from the EKS console.
Cocktail continuously monitors the status of provisioned clusters. If there are any changes in the EKS console, deleting the cluster from the console will trigger Cocktail to recreate the cluster.
To create a cluster, certain prerequisites need to be completed. Please refer to the following steps
1. Create a Cloud Provider
1) To create a cloud provider for cluster creation, click on the "+ Create" button in the [Provisioning] - [Cloud Providers] tab, and select AWS.
2) Register AWS authentication information in the basic information and click the "Save" button.
Account Name*
Enter the name for the registered AWS account
Description
Enter the description for the AWS account
AWS Access Key ID*
Input AWS Account ID
AWS Secret Access Key*
Input AWS Secret Access Key
AssumeRole ARN
Input AWS AssumeRole ARN value
3) Confirm successful registration.
2. Create an EKS Cluster
1) [Provisioning] - Navigate to the [Templates] tab, then click the "Start" button under the EKS (Elastic Kubernetes Service)​ item in the templates section
2) Select the previously created cloud provider information, choose the required version, and click "Save."
Account Name*
Select the registered cloud provider
Region*
Select the region for the cluster to be created
Cluster Name*
Register the name of the cluster to be created
Version*
Select the version of the cluster to be created
3) Once saved, the cluster status changes to "CREATING" as it is being provisioned.
4) Click on the "CREATING" status to monitor the cluster creation progress.
5) Click on the [Activity] tab to check the ongoing installation details.
6) Confirm the status changes to "RUNNING" when the cluster is successfully created.
3. Add AWS Node Group
1) Once the cluster configuration is complete, select the cluster, go to the [Resources] tab, and click "+ Add Node Group."
2) Enter the required information for the node group to be created and click "Save."
Node Group Name*
Enter the name of the Node to be created
Instance Type*
Select the instance (resource) to be created
Disk Size (GiB)*
Enter the disk capacity of the Node Group to be created
Desired Node*
Enter the number of Node Groups to be created
Min Node Count*
Enter the minimum number of Node Groups to be created when scaling in
Max Node Count*
Enter the maximum number of Node Groups to be created when scaling out
3) When the node group addition starts, the status is displayed in the "Node Group" section.
4) As the node group addition progresses, the status changes to "ACTIVE."
5) Check in the [Infrastructure] - [Clusters] tab if the cluster status and the number of nodes are displayed correctly.
4. Add Amazon EBS CSI Driver
1) Once the node group configuration is complete, select the cluster, go to the [Resources] tab, and click "+ Install Amazon EBS CSI Driver."
2) During the installation process, it takes some time to create resources, and later, confirm the installation completion.
3) Once the Amazon EBS CSI Driver installation is complete, the status is displayed in the "Amazon EBS CSI Driver" section.
4) Confirm the installation of the Amazon EBS CSI Driver in [Workloads] - [Deployments].
5. Add Cluster Autoscaler
1) Once the node group configuration is complete, select the cluster, go to the [Resources] tab, and click "+ Install Cluster Autoscaler."
2) During the installation process, it takes some time to create resources, and later, confirm the installation completion.
3) Once the installation is complete, the status is displayed in the "Cluster Autoscaler" section.
4) Confirm the installation of the Cluster Autoscaler in [Workloads] - [Deployments].
