I was given AWS Console access to an account with 2 instances running that I cannot shut down (in production). I would, however, like to gain SSH access to these instances, is it possible to create a new Keypair and apply it to the instances so I can SSH in? Obtaining the existing pem file for the keypair the instances were created under is currently not an option.

If this isn't possible is there some other way I can get into the instances?

For Elasticbeanstalk environments, you can apply a key-value pair to a running instance like this:

  • Create a key-value pair from EC2 -> Key Pairs (Under NETWORK & SECURITY tab)
  • Go to Elasticbeanstalk and click on your application
  • Go to configuration page and modify security settings
  • Choose your EC2 key pair and click Apply
  • Click confirm to confirm the update. It will terminate the environment and apply the key value to your environment.

You can actually add a key pair through the elastic beanstalk config page. it then restarts your instance for you and everything works.
