Why this?

The main purpose of this tool came about due to how annoying it is to encrypt files for Travis CI on Windows. Due to an encryption bug with the Windows version of the Travis CLI the encrypted files would fail to decrypt during the Travis CI build process.

What does it do?

This tool is a simple shell script that encapsulates a docker container with the Travis CLI (properly) installed allowing for file encryption to be done easily.

Dependencies

• Have Docker installed
• Have a command-line with bash scripting support

Usage

$ bash start.sh <file/directory> <repository>

Arguments:

• <directory>: the relative path of the directory that contains the files you want encrypted. Using an absolute path will not work at the moment.
  • Note: A directory containing more than one file will be compressed with tar before being encrypted.
• <repository>: the GitHub repository that the encrypted files will be tied to.
  • Ex: alex-greff/travis-cli-encryption-container

Upon running the script you will be asked by the Travis CLI to input your Github credentials.

Note #1: If prompted by Travis to install shell completion reply with n for no.

Once the encryption process is complete, use the instructions provided to add the provided decryption command to your .travis.yml file and make sure to only copy the encrypted files over to your repository as well.

Note #2: Due to how Open SSL works, if the directory contains more than one file then it must be compressed before being encrypted. Reference here for more information on how to handle it after decryption.
