Concourse-ECS

Wrapper script which writes environment variables to files and starts concourse. Useful if you want to store your SSH keys in the environment instead of a data volume when running in ECS.

Usage

Files can be created from environment variables matching the pattern FILE_n_PATH and FILE_n_CONTENTS. For example, the value of FILE_1_CONTENTS will be written to the value of FILE_1_PATH. n starts at 1 and ends when the environment variable doesn't exist.

Environment Variable	Description
FILE_n_PATH	The name of the file to create
FILE_n_CONTENTS	The contents of the file

Multiple pairs of environment variables can be specified.
