Create EFS volume on aws for k8s cluster

VPC var

Bash
vpc_id=$(aws eks describe-cluster \
--name wolkabout1 \
--query "cluster.resourcesVpcConfig.vpcId" \
--output text)

CIDR var

Bash
cidr_range=$(aws ec2 describe-vpcs \
--vpc-ids $vpc_id \
--query "Vpcs[].CidrBlock" \
--output text)

Create Sec groups

Bash
security_group_id=$(aws ec2 create-security-group \
--group-name EFS-sec-group-wl \
--description "EFS sec group wl" \
--vpc-id $vpc_id \
--output text)

Authorize Sec groups

Bash
aws ec2 authorize-security-group-ingress \
--group-id $security_group_id \
--protocol tcp \
--port 2049 \
--cidr $cidr_range

Create an Amazon EFS file system for your Amazon EKS cluster.

Bash
file_system_id=$(aws efs create-file-system \
--region eu-west-1 \
--performance-mode generalPurpose \
--query 'FileSystemId' \
--tags Key=Name,Value=whiteLabeling \
--output text)

Check Subnets of the cluster

List-subnets

Bash
aws ec2 describe-subnets \
--filters "Name=vpc-id,Values=$vpc_id" \
--query 'Subnets[*].{SubnetId: SubnetId,AvailabilityZone: AvailabilityZone,CidrBlock: CidrBlock}' \
--output table
