SSH Server Buildpack

This is a Cloud Native Buildpack that configures and runs sshd inside of a container.

Usage

The buildpack automatically generates a host key when you run a build:

$ pack build --buildpack jkutner/sshd myapp

You can customize the SSH configuration by creating a .ssh directory in your application, and adding files like:

• authorized_keys
• sshd_config

The buildpack will merge these with the default configuration.

Example

If I want to add my own public key to the SSH server's authorized_keys and restrict password authentication, I might run:

$ mkdir .ssh
$ ssh-keygen -f .ssh/id_rsa -t rsa -N ''
$ cat .ssh/id_rsa.pub > .ssh/authorized_keys
$ echo "PasswordAuthentication no" > .ssh/sshd_config
$ pack build --buildpack jkutner/sshd myapp

Then I can start my container

$ docker run -it -p 2222:2222 myapp

And in another terminal I can run:

$ ssh -p 2222 -i .ssh/id_rsa myuser@localhost
