Running an Ethereum Node with Docker

Running an Ethereum Node with Docker

Docker is a powerful tool for managing containers and run-time environments and, besides its many advantages, Docker can also be handy to keep your server tidy and secure.

#Docker allows to run operating systems, applications and tools in so called Containers. A #Container is an isolated environments that represents a autonomous host on its own – a bit in the same way a Virtual Machine does. Yet, Docker Containers are much lighter. They do not start an entire full-blown operating system for each Container instance. Instead, Docker uses #Linux kernel isolation mechanisms to run applications on the top of the host’s operating systems, yet keeping them isolated.

The Ethereum Go (language) team builds a Docker image of a “geth” node as part of their continuous build chain. Their Howto is more then enough to run your full node, mine below is just an enhanced example with volume, name, .. nothing fancy.

# i want to persist the blockchain in a volume

docker volume create --name=ethereum-data

# and limit cpu usage to 20% of all 8 cores –cpus=”.2″, give a name to container, more command line options

docker run --cpus=".2" -d -p 8545:8545 -p 30303:30303 \
 --name=ethereum-node \
 -v ethereum-data:/root/.ethereum ethereum/client-go \
 --rpc --rpcaddr ""

to stop and recreate the container

docker stop ethereum-node && docker rm ethereum-node

to go inside the container

docker exec -it ethereum-node bash

to test the RPC api

curl -X POST --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":1}' localhost:8545


curl -H "Content-Type: application/json" -X POST \
 --data '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest", true],"id":1}'


You may want to register your node at The Ethereum (centralised) network status monitor , in that case just follow 

My Ethereum node is now running at

A better status page is in development using PHP with RPC
