As part of the process to build my docker container I need to pull some files from an s3 bucket but I keep getting fatal error: Unable to locate credentials even though for now I am setting the credentials as ENV vars (though would like to know of a better way to do this)
So when building the container I run
docker build -t my-container --build-arg AWS_DEFAULT_REGION="region" --build-arg AWS_ACCESS_KEY="key" --build-arg AWS_SECRET_ACCESS_KEY="key" . --squash
And in my Dockerfile I have
ARG AWS_DEFAULT_REGION
ENV AWS_DEFAULT_REGION=$AWS_DEFAULT_REGION
ARG AWS_ACCESS_KEY
ENV AWS_ACCESS_KEY=$AWS_ACCESS_KEY
ARG AWS_SECRET_ACCESS_KEY
ENV AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY
RUN /bin/bash -l -c "aws s3 cp s3://path/to/folder/ /my/folder --recursive"
Does anyone know how I can solve this (I know there is an option to add a config file but that just seems an unnecessary extra step as I should be able to read from ENV).
