Dockerfile

# How to test changes to this file
# docker build -f Dockerfile -t gcr.io/celo-testnet/geth:$USER .
# To locally run that image
# docker rm geth_container ; docker run --name geth_container gcr.io/celo-testnet/geth:$USER
# and connect to it with
# docker exec -t -i geth_container /bin/sh
#
# Once you are satisfied, build the image using
# export COMMIT_SHA=$(git rev-parse HEAD)
# docker build -f Dockerfile --build-arg COMMIT_SHA=$COMMIT_SHA -t gcr.io/celo-testnet/geth:$COMMIT_SHA .
#
# push the image to the cloud
# docker push gcr.io/celo-testnet/geth:$COMMIT_SHA
#
# To use this image for testing, modify GETH_NODE_DOCKER_IMAGE_TAG in celo-monorepo/.env file
