Docker Fun – Play Text Adventures

zorkThis time around in the Docker Fun series, we are getting a little more ambitious. Zork was one of the first popular text adventures, building on the work of Will Crowther and Dan Wells who created the mainframe game Colossal Cave (aka Adventure).

While text adventures at that time were struggling with two word commands like “Open Door”, Zork understood much more elaborate command like “Hit the grue with the Elvish sword”. The developers of Zork founded Infocom and eventually released a number of sequels and prequels to Zork as well as several dozen other text adventures in a number of different genres.

Like last month’s this is an easy container to implement, consisting of only a three line Dockerfile.

ETLIllustration of ETL

This is an updated graphic that hung in my office space at work for a number of years. I was asked many times, what I did, and had to explain what ETL meant. Eventually I came up with this idea, grabbed some stock images from iStockPhoto and put it together. Enjoy!
