How to Dockerize an Ethereum Decentralized Application
summary
Builds a simple Solidity contract that saves and fetches a message, deploys it to a local Ganache blockchain, and exposes four Node.js routes: compile, deploy, get, set. Uses Dockerfiles for three services (Ganache, server, React), notes the Ganache container must bind host as 0.0.0.0, and the server image pins Node 8.12.5 with Python2/GCC to satisfy web3 dependencies. React uses a two-stage build so the final image is about 24 MB, and images are pushed to Docker Hub via docker-compose.
