How can i automate script executions in aws EC2 using go sdk?

I'm building an app that manages multiple ec2 instances using the go sdk. I would like to run scripts on these instances in an automated way.

How can I achieve that ? I don't think os.command => ssh => raw script stored as string in code is the best practice. Is there any clean way to achieve this ?
Thanks

To bootstrap your instance, you would create a UserData script. The script runs only once, just after your instance is launched.

For other execution of commands remotely, you can use SSM Run Command to run command on a single or multiple instances.

The way you suggest is actually valid and can work. I agree with you though, it wouldn't be my first choice either. I would either use the package golang.org/x/crypto/ssh in the standard library or an external solution like github.com/appleboy/easyssh-proxy.

I would lean towards the default library but if you don't have a preference there then the Scp function of the latter package might be especially of interest to you. You can find examples of this in the readme of the project.

EDIT: After seeing Marcin's answer, I think my answer is more the plain SSH answer, AWS independent. For the idiomatic answer for AWS please definitely look at his suggested solution!
