How to scp from remote host to bamboo EC2 instance?

Micah Kramer

After googling around, I stumbled upon this: https://answers.atlassian.com/questions/13413922

Which led me to experiment for the past several hours with decent success. However, I seem to have run into a snag.

The story so far:

I have a build in bamboo that needs to scp a file from a remote server to the Amazon EC2 instance that bamboo is running on. 

I can ssh into the EC2 isntance as root and, using an ssh key, successfully scp the desired file from the remote server to the EC2 instance.

I can ssh into the EC2 as the ec2-user provided by bamboo and, after appending "sudo" am again successful.

However, when I paste this command into a script task in bamboo, it fails.

If I leave off the "sudo" I get: "Host key verification failed.".

If I append the "sudo" I get: "sudo: no tty present and no askpass program specified".

By all accounts this should be working, so there must be something different about the user/permissions/something to do with bamboo running the command as opposed to myself, but I simply don't know what and I can't find any documentation that states this difference. 

Any insight would be greatly appreciated.

Thank you.

While Przemek's answer will work, security wise it is not the best answer. If your bamboo instance is compromised through a fault in bamboo's web services, the attacker would have total control over your bamboo machine. And since bamboo usually has privileged control over webservers for deployment, those could be at risk too.

When bamboo runs scripts, its running as the bamboo user account on the bamboo machine. What you'll want to do is either handle these things using options to ssh (like ignore host key verification), or you can su to the bamboo user (su - bamboo), and run your ssh command and answer yes to adding the host key to the known hosts (this will live in /home/bamboo/.ssh).
