Add arbitrary ssm paramters to an existing docker image as environment variables at run time

readme.md

Check the upstream readme for more inforation on how to specify the desired ssm parameters https://github.com/binxio/ssm-get-parameter/blob/master/README.md

the idea is you just update image name in build.sh for your project and then use your custom docker image which wraps the image the project actually needs and then that ssm-get-parameter binary handles the env var translation of any env vars you set that have the magic ssm:// prefix in the value

build.sh

#!/bin/bash

IMAGENAME="redis:latest"
docker pull $IMAGENAME
ORIGINAL_ENTRYPOINT=$(docker inspect --format='{{ .Config.Entrypoint }}' $IMAGENAME)
ORIGINAL_CMD=$(docker inspect --format='{{ .Config.Cmd }}' $IMAGENAME)

docker build --build-arg IMAGENAME=${IMAGENAME} --build-arg ORIGINAL_ENTRYPOINT=${ORIGINAL_ENTRYPOINT} --build-arg ORIGINAL_CMD=${ORIGINAL_CMD} -f Dockerfile .
