 1 | # dockerfile-to-shell-script
 2 | Converts a Dockerfile to a shell script, using a series of shoddy sed commands.
 3 | 
 4 | Caveats: Only tested with our relatively limited Dockerfiles, and the output 
 5 | will *definitely* need examining.
 6 | 
 7 | There are some parameters at the top - 
 8 |     HOME_DIRECTORY Specify a home directory here for the environment you will be deploying to
 9 |     CONVERT_HOME_DIRECTORY If you want to convert the home directory statements to tilde's, set this to 1.
10 |     
11 | Usage ./docker_to_sh.sh
12 | 
13 | Software as is, used for Good, not Evil. THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, &c &c. I am not proud of this.
