# This script will explain how to transfer a file to EC2 using SSM ONLY! | |
# You will need to have permission to run SSM commands on the target machine and have sudo access as well | |
# Infos | |
INSTANCE_ID=i-1234567890 | |
FILE_NAME=the_file.tar.gz | |
# Step 1: Run command on machine to install netcat and dump from port to filename | |
# < Start session | |
aws ssm start-session --target $INSTANCE_ID --document-name | |
# < (On target machine) : | |
cd && sudo yum install nc -y && sudo nc -l -p 1234 > the_file.tar.gz | |
# Step 2: On another shell, open a port-forwarding session from your machine to the target machine | |
aws ssm start-session --target $INSTANCE_ID --document-name AWS-StartPortForwardingSession --parameters '{"portNumber":["1234"],"localPortNumber":["1234"]}' | |
# Step 3: On yet another shell, cat the source file into the transfer port on localhost over the tunnel | |
nc -w 3 127.0.0.1 1234 < the_file.tar.gz | |
# Step 4: Once the command in step 3 finishes, close all of the other shell sessions. Your file should be on the target now. |
That's handy! I had to remove the --document-name
on the first start-session
call.
similarly, have you tried copying a file from ec2 to your local machine without using s3
Extremely helpful! Thank you for sharing.
