Local Environment For Ethereum Smart Contracts Development Using Docker

Local Environment For Ethereum Smart Contracts Development Using Docker

Local environment for Ethereum Smart Contracts development using Docker Notlong time ago I had a chance to attend series of events about blockchain. Quickly I became interested in the technical side of the trendy idea. After building simple Bitcoin wallet I decided to try something more advanced. In this article I will share a toolset for building, deploying and testing locally your Ethereum Smart Contracts using Docker. First of all there are several options you should consider before start. To test stuff on Ethereum blockchain you could use the next tools Truffle and Ganache - your personal local Ethereum like blockchain and full toolset for smart contracts. Best for quick start. Setup your own local copy of Ethereum. Closest to real world. As for me I've chosen the last one, because I wanted to be close to real world Ethereum Blockchain and still have the possibility to configure all tools myself to get additional knowledge about how it works. Quickly I understood that I need to setup several Ethereum nodes locally and some tool to make sure they are functioning properly. When it comes to trying new software on my machine I prefer Docker. Nothing makes me so happy than running dozens of services without any knowledge how to setup them :D Quick search gave me the result I wanted: already existing Docker Compose based Ethereum solution , which allows to bring up as many Ethereum nodes as you wish, has predefined test users with some ETH on the balance and Netstat to monitor the nodes. Let's take a look at docker-compose.yml file for the project (I skipped volumes and some other stuff) Bootstrap container acts as the node you can use for RPC and setups initial users. To make it close to real world there is second node called eth, which participates in validating transa Continue reading >>

Building Private Ethereum Networks With Docker Compose

Building Private Ethereum Networks With Docker Compose

In my previous article about building a blockchain application , I shared some of the tools, tips and techniques I used to create an end-to-end blockchain web application. Lets hone in on a specific part of that and explain in more depth how I built an underlying Ethereum private blockchain for testing purposes. I mentioned that I predominantly used testrpc to stand up a simple, single-node Ethereum instance which had the APIs exposed and some accounts pre-filled with Ether for testing. Testrpc is a great tool, super simple and fast to get started, which makes it ideal for development and if you are new to the tech. However there are some situations where you might want some extra flexibility or you need to test different scenarios where you require a more production like setup. These include - Testing the effects of a network of nodes (e.g. a multi-node Ethereum cluster with each node in sync with other nodes via the P2P protocol) Access to other Ethereum APIs, for example the management API Access to the Ethereum JavaScript Console The confidence of developing against a full Geth node Easier integration with or ability to test alongside other tools or technology such as IPFS If you find yourself having to set up a private Ethereum cluster (as I did) youll find that its not actually a straightforward process. While there are one or two pretty clear tutorials out there as well as some scripts both for me had some problems. The scripts prefer that you are running Ubuntu, the preferred/recommended platform for Ethereum and the tutorials contain anywhere between 5-20 steps. I wanted a simple, repeatable and cross platform way to bring up and tear down my clusters. Enter Docker and Docker Compose . Today Im announcing our open-sourced ethereum-docker which contains a bunch Continue reading >>

Building An Ethereum Environment With Docker

Building An Ethereum Environment With Docker

Building an Ethereum Environment with Docker Tasha Blockchain & Crypto / System 4 Comments Docker is a powerful tool for managing containers and run-time environments and, besides its many advantages, Docker can also be handy to keep our development workstation tidy while playing with all kind of cool technologies. In addition, containerisation adds an important security aspect by providing a strong isolation from the hosts affairs. In this writing, we are going to harness the power of Docker to build a first Ethereum work and development environment. The Ethereum Go (language) team builds a Docker image of a geth node as part of their continuous build chain. The C++ team does the same and we can use these images to quickly run an Ethereum node in our local environment. Alternatively, we can script our own images, which brings some advantages as we will see later. Before starting with Ethereum however, we need to make a very quick Docker Basics in 120 Seconds intermezzo. If you know Docker already, just skip this part Docker allows to run operating systems, applications and tools in so called Containers. A Container is an isolated environments that represents a autonoumous 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 hosts operating systems, yet keeping them isolated. In order to start a Container, Docker uses Images. An image is basically theimageof an environment before running it (kind like an installation ISO/disk) and they contain the strict minimum required to run this environment. Images represent the common and stable starting po Continue reading >>

We are hosting latest development snapshots (and in the future alsoreleases) at docker hub. You can run these images as follows: Before running the image, you should pull the latest version and preparethe data directories: # get the lastest version from dockerhub (redo for updates).docker pull ethereum/client-cpp# create mountable datadirs; blockchain/account data will be stored theremkdir -p ~/.ethereum ~/.web3 These steps need to be done only once. For upgrading to a new version dothe docker pull ... again. docker run --rm -it \ -p 127.0.0.1:8545:8545 \ -p 0.0.0.0:30303:30303 \ -v ~/.ethereum:/.ethereum \ -v ~/.web3:/.web3 \ -e HOME=/ \ --user $(id -u):$(id -g) \ ethereum/client-cpp This will write data to ~/.ethereum and ~/.web3/ on your host and runthe client with your users permissions. For most cases this should besufficient and the client should behave exactly as if run from a local build. If you want the rpc port reachable from the network (not recommended, never do thisif you have valuable data or private keys on your machine), replace-p 127.0.0.1:8545:8545 by -p 0.0.0.0:8545:8545. For convenience, you can create the file /usr/local/bin/docker-eth with thefollowing content: #!/usr/bin/env shmkdir -p ~/.ethereum ~/.web3if ! id -nG $(whoami)|grep -qw "docker"; then SUDO='sudo'; else SUDO=''; fi$SUDO docker run --rm -it \ -p 127.0.0.1:8545:8545 \ -p 0.0.0.0:30303:30303 \ -v ~/.ethereum:/.ethereum \ -v ~/.web3:/.web3 \ -e HOME=/ \ --user $(id -u):$(id -g) \ ethereum/client-cpp [email protected] And make it executable with chmod +x /usr/local/bin/docker-eth. Now you canstart the client with: Note: The docker-eth command will accept the same flags as the raw ethcommand. If you want to attach to the node, you can either just use mist (it willdetect the node automatically), use geth Continue reading >>

Multi-node Private Ethereum Network Using Docker

Multi-node Private Ethereum Network Using Docker

Multi-Node Private Ethereum Network using Docker In the Introduction to Ethereum series, we demonstrated the simple vehicle buying use-case (involving the buyer, the dealer, and the dmv) using a single node on a private Ethereum network. In reality, if one were to setup a private Ethereum network in any Enterprise, it would involve more than one node in the network. In this article, we will lay out the steps to setup a multi-node private Ethereum network (one for each of the entities - the bank, the buyer, the dealer, and the dmv). In addition, we will leverage the official Docker images for the Ethereum client and the Solidity compiler, rather than the approach of installing the necessary software components as we did in Part 1 of Introduction to Ethereum series. Special callout to Sudhaker Raj for helping me sort out some issues with running an Ethereum node using Docker. The setup will be on a Ubuntu 16.04 LTS based Linux desktop. Ensure Docker is installed and setup. Else, refer to the article Introduction to Docker . Assuming that we are logged in as polarsparc and the current working directory is the home directory /home/polarsparc, we will setup a directory structure by executing the following commands: Now, change the current working directory to the directory /home/polarsparc/Ethereum. For our exploration, we will be downloading and using the official docker images ethereum/client-go:alltools-v1.7.3 for Ethereum and ethereum/solc:nightly for Solidity. To pull and download the docker image for Ethereum, execute the following command: docker pull ethereum/client-go:alltools-v1.7.3 The following should be the typical output: alltools-v1.7.3: Pulling from ethereum/client-go b56ae66c2937: Pull complete cd6eff31471d: Pull complete c97a5da0e9b5: Pull complete Digest: Continue reading >>

How Does One Setup A Private Network With Ethereum Docker Images?

How Does One Setup A Private Network With Ethereum Docker Images?

How does one setup a private network with ethereum docker images? I'm confused about how to get/access geth that is inside the container. it seems though that this image is designed to work on the public network. do i have to make my own dockerfile? What do I need to include in that dockerfile and how do I access geth? Should geth be installed on the 'host' os/where the image/containers are or can it be solely in the docker container? If you want to create a private network, you need to create your own genesis file (see the "Operating a private network" section of the documentation of the client-go Docker image . If you create that in a folder, and then are on the command line in that folder, running: docker run --name ethereum-node -v ${PWD}:/private-data \ ethereum/client-go init /private-data/genesis.json Then you should be able to bring up the node with the command they give: docker run -d --name ethereum-node -v /Users/alice/ethereum:/root \ -p 8545:8545 -p 30303:30303 \ ethereum/client-go --fast --cache=512 If you want to attach to that running node to get at the Javascript CLI, do: docker exec -it ethereum-node /user/bin/geth attach Geth does not need to be installed on the host OS, it can just reside in the Docker container. If you want to control where the blockchain data gets saved, you can alter the -v commands to point to a different location in the host OS to store the data the container generates.

Building An Ethereum Playground With Docker (part 2dockerimage)

@vertigobr Founder & CTIO, disrupting things for fun. Building an Ethereum playground with Docker (part 2 DockerImage) I have updated this article on December/2017. I no longer create a custom Docker image, because Ethereum official image already brings an all-tools version that includes bootnode and other treats. This is the second article in an ongoing series Building an Ethereum Playground with Docker. The articles already published are: We will cover using the official ethereum/go-ethereum Docker image, playing with Ethereum Wallet, provisioning the ethereum nodes on public clouds and deployment of a sample app. This article uses " ethereum/client-go " Docker image to run several Ethereum nodes locally (and safely). It also assumes you have a Docker engine available to you (and know a bit about it), probably after installing Docker for Mac or Docker for Windows on your notebook. All sources are located in . There is a public official image "docker pull ethereum/client-go" that will serve as the base of this work. We will create scripts with some functionality and configuration options to make it generally useful for our evil machinations. This original public base image is a nice piece of work: you can use it to participate on the main public Ethereum network with a simple command: The starting point is the creation of a "genesis.json" file that defines the genesis block of the blockchain. The "genesis.sh" script does that for you, and it can be edited to provide custom values for some variables Some variables on the top of this script can be modified to define your very own genesis block, the main point being that all containers will mount the same genesis.json file when launched with the helper scripts. Nodes that share the same genesis block and are capable of f Continue reading >>

enumerated a few common parameter combos to get you up to speed quickly on how you can run your By far the most common scenario is people wanting to simply interact with the Ethereum network: create accounts; transfer funds; deploy and interact with contracts. For this particular use-case the user doesn't care about years-old historical data, so we can fast-sync quickly to the current Start geth in fast sync mode (--fast), causing it to download more data in exchange for avoiding processing the entire history of the Ethereum network, which is very CPU intensive. Bump the memory allowance of the database to 512MB (--cache=512), which can help significantly in sync times especially for HDD users. This flag is optional and you can set it as high or as low as you'd like, though we'd recommend the 512MB - 2GB range. Start up Geth's built-in interactive JavaScript console , (via the trailing console subcommand) through which you can invoke all official web3 methods This too is optional and if you leave it out you can always attach to an already running Geth instance Transitioning towards developers, if you'd like to play around with creating Ethereum contracts, you almost certainly would like to do that without any real money involved until you get the hang of the entire system. In other words, instead of attaching to the main network, you want to join the test network with your node, which is fully equivalent to the main network, but with play-Ether only. $ geth --testnet --fast --cache=512 console The --fast, --cache flags and console subcommand have the exact same meaning as above and they are equally useful on the testnet too.
