Here is an article about connecting Bitcoind and BTC RPC Explorer to Docker:

Connecting Bitcoin (Bitcoind) and BTC RPC Explorer to Docker

As a cryptocurrency enthusiast, you’re probably familiar with the importance of having multiple tools working together. In this article, we’ll look at how to connect Bitcoind, a popular decentralized cryptocurrency software, to BTC RPC Explorer, a graphical user interface for querying Bitcoin blockchain data.

Why connect Bitcoind and BTC RPC Explorer?

Before diving into the setup process, let’s quickly discuss why you might need to connect these two services:

• Decentralized Applications: Many DeFi (Decentralized Finance) and NFT (Non-Fungible Tokens) projects rely on Bitcoin as their own cryptocurrency. To interact with these applications, they need access to Bitcoind.

• Research and Development: Developers and researchers often need to query Bitcoin blockchain data using tools such as BTC RPC Explorer. The Bitcoind connection ensures a seamless interaction with this data.

Configuring Docker Containers

To connect Bitcoind and BTC RPC Explorer in Docker, follow these steps:

Step 1: Extract the official Bitcoind image

First, we need to extract the official Bitcoind image from Docker Hub. Run the following command:

docker pull bitcoind/bitcoind:latest

This will download the latest version of Bitcoind.

Step 2: Create a new Dockerfile for BTC RPC Explorer

Create a new file named Dockerfile in the same directory as your existing files. This file will contain instructions for creating a Docker image for BTC RPC Explorer.

Use the official Node.js image
FROM node:latest

Set the working directory in /app
WORKDIR /app

Copy .gitignore and Makefile
COPY ./.gitignore Makefile .

Installing dependencies
RUN npm install -g bitcoin-cli

Building the application
RUN npm run build

Open the port
EXPOSE 8545

Start the application when the container is started
CMD ["./node_modules/.bin/bitcoin-cli", "--rpc", "

This Dockerfile uses the official Node.js image, sets up the working directory for the application, installs dependencies using npm, compiles the application, opens port 8545 (the default RPC port), and defines a CMD' command to launch the application when the container is started.

• Odin for Bitcoind (bitcoind/dockerfile)

• Odin for BTC RPC Explorer (btxrpc/dockerfile)

docker build -t bitcoind-bitcoin-core .
docker build -t btxrpc-btc-rpc .

• For Bitcoind: docker run -d –name bitcoin-container bitcoind/bitcoind:latest

• For BTC RPC Explorer:docker run -d –name xrpc-container btxrpc/btxrpc:latest

The–name’ flag creates a temporary name for each container that is stored in the Dockerfile. This allows you to easily manage multiple containers without conflicts.

Step 5: Access Bitcoind and BTC RPC Explorer

Once the containers are running, you can access Bitcoind and BTC RPC Explorer using their respective URLs:

• Bitcoind:

• BTC RPC Explorer: (replace xrpc-container with your actual container name)

Conclusion

After completing these steps, you have successfully connected Bitcoind and BTC RPC Explorer in the Docker environment. This setup ensures seamless communication between the two services, making it easy to access Bitcoin blockchain data with tools like BTC RPC Explorer.

In conclusion, remember that this is just one way to connect Bitcoind and BTC RPC Explorer to Docker. You can experiment with different configurations and images to find what works best for your particular use case.
