to your local machine using kubectl cp : kubectl cp :/tmp/ ./ . 2. Using the Skbn Tool
skbn cp s3:// / k8s:// / / / 3. Mounting S3 as a Volume
with the role's ARN: eks.amazonaws.com/role-arn: arn:aws:iam:: :role/ . kubectl download s3
This allows you to define a PersistentVolume (PV) backed by an S3 bucket.
To make S3 files appear as "local" files within your pods automatically, use the Mountpoint for S3 CSI driver . to your local machine using kubectl cp : kubectl cp :/tmp/
When interacting with S3 from Kubernetes, avoid hardcoding AWS credentials. Instead, use : Create an IAM Role with s3:GetObject permissions.
to your pod, which allows the AWS CLI inside the pod to authenticate securely. Copy files between s3 and kubernetes container Mounting S3 as a Volume with the role's ARN: eks
Once mounted, you can use standard kubectl cp to "download" from the mount point to your local machine as if it were a normal directory. Security Best Practices
For a more direct "S3 to Kubernetes" transfer, the open-source tool Skbn allows you to copy files directly between S3 and pods without intermediate steps:
