Running a Private Ethereum Blockchain using Docker

Put genesis.json, Dockerfile, docker-compose.yml and .env files together in the same folder. Then run the command.

docker-compose up

.env

# The ID of Ethereum Network
NETWORK_ID=1214

# The password to create and access the primary account
ACCOUNT_PASSWORD=5uper53cr3t
