# This Dockerfiles configures a container that is similar to the Travis CI
# environment and can be used to run tests locally.
#
# build the image:
#   docker build -t restic/test .
#
# run all tests and cross-compile restic:
#   docker run --rm -v $PWD:/home/travis/restic restic/test go run run_integration_tests.go -minio minio
#
# run interactively:
#   docker run --interactive --tty --rm -v $PWD:/home/travis/restic restic/test /bin/bash
#
# run a subset of tests:
#   docker run --rm -v $PWD:/home/travis/restic restic/test gb test -v ./backend
#
# build the image for an older version of Go:
#   docker build --build-arg GOVERSION=1.6.4 -t restic/test:go1.6.4 .
