This blog post covers some technical topics about the Bitcoin block chain, which you might want to read up on the subject beforehand. The standard Bitcoin client, Bitcoin Core has three networks it can run on: This is the real Bitcoin network, with the block chain that everyone uses.
Every now and then the developers nuke the ledger to prevent selling off testnet bitcoins, and also to reset the mining difficulty low enough so a CPU can effectively mine. Currently it is called testnet3. The testnet runs on a different TCP port, has a different genesis block , and the Bitcoin addresses start with different letters. New in Bitcoin Core 0. It also has its own genesis block, and when you start your client, no peers are registered, and nothing is initially mined by anyone.
After the initialisation of the Bitcoin Core daemon, i. I have created a Docker image which simply allows you to run Bitcoin Core in a Docker container. After cloning the repository, hop into it and run:. There is a version 0. We are going to run two docker instances, one for Alice and one for Bob. This section outlines how to build the image and run the container.
Check out the Docker doc Get Started. Make sure you are working in the directory containing the Dockerfile. The first time you build the image may be slow, especially if the Ubuntu image needs to be downloaded.
See this StackOverflow question: Docker updating image along when dockerfile changes. Refer to the Docker Docs run reference for all the details. Note that docker run creates a new container each time. To have Docker clean up the container when it exits, use the --rm flag. Read more about the Clean up command in the Docker Docs: Start Bitcoin in headless mode, specifying the datadir as the node directory which contains the bitcoin.
Both the node directory and the bitcoin. You should see the output Bitcoin server starting before being returned to the prompt. From outside the Docker container we can use curl to confirm connectivity to the Bitcoin node. When the container was started using docker run Leave open the terminal window with the Docker container and the bitcoind daemon running.
This should return the same result as the getinfo command issued earlier within the Docker container. Also refer to this StackExchange question: Can I use curl to call getInfo from a the Bitcoin server? I hope this article has served as an initial introduction to running Bitcoin in regtest mode within a Docker container.
For a more advanced example please have a look at the excellent bitcoin-testnet-box available on GitHub.
