nonroot CentOS Dockerfile

[JohnnySheffield]

Usage - CentOS

Builds a lightweight non-root Parity docker image:

git clone https://github.com/paritytech/parity-ethereum.git
cd parity-ethereum
./docker/centos/build.sh

Fully customised build:

PARITY_IMAGE_REPO=my-personal/parity \
PARITY_BUILDER_IMAGE_TAG=build-latest \
PARITY_RUNNER_IMAGE_TAG=centos-parity-experimental \
./docker/centos/build.sh

Default values:

# The image name
PARITY_IMAGE_REPO - parity/parity

# The tag to be used for builder image, git commit sha will be appended
PARITY_BUILDER_IMAGE_TAG - build

# The tag to be used for runner image
PARITY_RUNNER_IMAGE_TAG - latest

All default ports you might use will be exposed:

#           secret
#      ipfs store     ui   rpc  ws   listener  discovery
#      ↓    ↓         ↓    ↓    ↓    ↓         ↓
EXPOSE 5001 8082 8083 8180 8545 8546 30303/tcp 30303/udp

on dcb5710 i've started to play around with builder pattern. It's a bit more demanding as there is 2 Dockerfiles and a .sh script, but resulting in a smaller final image (90 mb on dockerhub) vs official parity image 139 mb on dockerhub

Basic idea is to first build and start a "builder dockerfile", then extract the parity binary outside of the image, then build a "runner dockerfile" with the newly built binary.
