How to build the image from source

You must provide two build-time arguments when building this Docker image, BUILD_DATE and BUILD_VERSION.

docker build \
  --build-arg BUILD_DATE=$(date -u +'%Y-%m-%dT%H:%M:%SZ') \
  --build-arg BUILD_VERSION=0.7.1 \
  -t shuppet/mailcatcher:0.7.1 \
  -t shuppet/mailcatcher:latest \
$PWD

Then the resulting image can be pushed to the shuppet/mailcatcher Docker Hub repository:

docker push shuppet/mailcatcher:0.7.1
