Technical requirements
For this chapter, you will need to have access to a Linux machine running Docker. We recommend that you use the setup you have been using so far in this book.
In addition to this, you will need an account on Docker Hub in order to access images located there. If you have not already set one up, you can do so at https://hub.docker.com.
If you have an existing container or service running SSH, this can be used later in this chapter. If not, do not worry. We provide a link to an example Dockerfile from the official Docker documentation you can use instead if you wish.
