tomvoboril/variable-swap repository overview

Replace env-notated strings with their variables

This simple image will use the envsubst command from the gettext package to replace all strings "annotated like variables" with the enviromentals passed into the container, or with existing variables injected by kubernetes etc.

The sample .env file defines new fortunes for the https://github.com/jhunt/o-fortuna⁠ sample fortune generator.

run with the following command:

docker run --rm --env-file variable-swap.env -v ${PWD}:/app tomvoboril/variable-swap

For a kubernetes example, see: https://github.com/tvoboril/file-injecternitiator⁠
