About this version
First you'll need to do the bootstrapping steps described below.
STACK_NAME="MyStack"
ASG_NAME="${STACK_NAME}Jump"
SSH_KEY_NAME="$HOME/.ssh/${AWS_PROFILE}-${ASG_NAME}.pem"
# Set us up the Jumpbox
aws autoscaling set-desired-capacity --auto-scaling-group-name "$ASG_NAME" --desired-capacity 1
# Find the jump box instance
while
JUMP_INSTANCE_ID=$(aws autoscaling describe-auto-scaling-groups --query "AutoScalingGroups[?AutoScalingGroupName=='$ASG_NAME'].Instances[].InstanceId" --output=text)
[[ -z "$JUMP_INSTANCE_ID" ]];
do
sleep 10
done
LOCAL_PORT=$(python -c 'import socket; s=socket.socket(); s.bind(("", 0)); print(s.getsockname()[1]); s.close()')
ssh -f -i "$SSH_KEY" -L "$LOCAL_PORT:$INTERNAL_HOST:$INTERNAL_PORT" "ec2-user@$JUMP_INSTANCE_ID" sleep 10 && \
exampleClient --host localhost --port "$LOCAL_PORT" ...You only have to run these steps once, but you need to do it before you try connecting.
- Install the session manager plugin:
curl "https://s3.amazonaws.com/session-manager-downloads/plugin/latest/mac/sessionmanager-bundle.zip" -o "sessionmanager-bundle.zip"
unzip sessionmanager-bundle.zip
# use python3 instead of python2 on your mac
python3 sessionmanager-bundle/install- Make sure the following is in your
~/.ssh/config:
# SSH over Session Manager
Host i-* mi-*
ProxyCommand sh -c "aws ssm start-session --target %h --document-name AWS-StartSSHSession --parameters 'portNumber=%p'"
- Get the SSH key such as
~/.ssh/myAccount-MyStackJump.pem:
export AWS_PROFILE=myAccount
export AWS_REGION=us-west-2
click a
STACK_NAME="MyStack"
ASG_NAME="${STACK_NAME}Jump"
# Fetch the SSH key from SecretsManager
SSH_KEY_NAME="$HOME/.ssh/${AWS_PROFILE}-${ASG_NAME}.pem"
aws secretsmanager get-secret-value --region="$AWS_REGION" --output=text --query SecretString --secret-id "ec2-ssh-key/${ASG_NAME}/private" > "$SSH_KEY_NAME"
chmod 400 "$SSH_KEY_NAME"
