Yes, I am using it and no, I am not worried.<p>If someone were to break through my webservice and then break out of the Docker container they'd be on an AWS Elastic Beanstalk container that doesn't even have public keys for SSH on it nor a running SSH server (i.e. nothing of value). If there is the slightest hint that something is not right with one of these containers I just terminate the whole instance and replacements automatically spawn.<p>Since these are all deployed via continuous integration <i>I</i> do not even have SSH access to the instances--they are disposable.<p>And if anyone happens to be curious:<p>Commit -> Travis-CI -> S3 -> Elastic Beanstalk staging environment<p>If staging goes well then we merge to another branch which ends up in an Elastic Beanstalk production environment.
