Running an SSH server in a container on Apcera

SSH is the Swiss Amy Knife of system administration and provides the easiest way to manage a system remotely. When running containers, there is typically someway to connect to a container’s shell from a client that communicates through an API like Docker or by using an SSH solution which is how Apcera does it. Some applications that run in containers may require SSH access to communicate with other containers or services. For example, Hadoop is a popular cluster application that uses a distributed filesystem spread across many nodes and communicates with each other via SSH. Let’s take a look on how to setup an SSH server running inside a capsule (a minimal OS container) on the Apcera Platform.

Life has been very difficult for this migration because Swarm requires a lot of handholding and lacks the failover automation that I need. I began researching the Apcera Platform and tried out the community edition that users can try for free. The areas that I focused on for my needs regard ease of use and workload portability.
