You can associate a specific SSH key pair with control plane or node pool instances during creation.
To generate an asymmetric private key and import its public key into AWS, run the following commands:
ssh-keygen -t rsa -m PEM -b 4096 -C "COMMENT" \
-f SSH_PRIVATE_KEY -N "" 1>/dev/null
aws ec2 import-key-pair --key-name SSH_KEY_PAIR_NAME \
--public-key-material fileb://SSH_PRIVATE_KEY.pub
Replace the following:
SSH_PRIVATE_KEY
: a file name to save the key inSSH_KEY_PAIR_NAME
: a name you choose for the key pairCOMMENT
: a text string describing the key
