This is just the first 10 lines, there are well over 100 in the total output. Notice how the output seems to be squeezed into a table.

Here's the output from the same command when executed from the command line:

$ sudo docker build .

Is there something that I'm doing to squeeze everything into a table like this?

    I'm on Windows now, so I can't test, but I think you can fix this by adding :results verbatim to the #+BEGIN_SRC line. (The default is to guess if the output is tabular data nad make a table if it is, I guess Babel's guess is wrong in this case; verbatim tells Babel the output is just literal text.) – Omar Jan 3 '17 at 19:28
  • Yup, that did it Omar, thanks! Would you like to answer so I can accept it or should I answer it myself? – Tom Purl Jan 3 '17 at 20:11
  • I've added an answer now. – Omar Jan 4 '17 at 4:56

The default for Babel results blocks (in most languages) is try to guess what the best format is. Here Babel seems to be guessing incorrectly that the output of your block is tabular data. You can use :results verbatim to tell Babel that the result should be treated as literal text. (There is also :results table to force the results to be in a table.)
