To run, I need:
|
|
- to be in a container generated by the Dockerfile at the top of the Docker
|
|
repository;
|
|
- to be provided with the location of an S3 bucket and path, in
|
|
environment variables AWS_S3_BUCKET and AWS_S3_BUCKET_PATH (default: '');
|
|
- to be provided with AWS credentials for this S3 bucket, in environment
|
|
variables AWS_ACCESS_KEY and AWS_SECRET_KEY;
|
|
- a generous amount of good will and nice manners.
|
|
The canonical way to run me is to run the image produced by the Dockerfile: e.g.:"
|
|
|
|
docker run -e AWS_S3_BUCKET=test.docker.com \
|
|
-e AWS_ACCESS_KEY=... \
|
|
-e AWS_SECRET_KEY=... \
|
|
-i -t --privileged \
|
|
docker ./hack/release.sh
