# Step 2: Setup the network for Züs components ### Build and Configure 0dns 0dns service is responsible for connecting to the network and fetching all the magic blocks from the network, which are saved in the DB.\ \ 1\. Navigate to 0dns directory ``` cd 0dns ``` 2\. Open the 0dns configuration file(0dns.yaml) using the nano editor. ``` nano docker.local/config/0dns.yaml ``` 3\. Disable both `use_https` and `use_path` (set them to `false`).This is required to fix the miner and sharder URLs so they work locally.

4\. Save the changes and run the following command inside the 0dns directory ``` ./docker.local/bin/build.sh ``` Here is the screenshot of the terminal after a successful build:

### Set up a Docker Network To create sharder, blobber, miner containers and allow interaction between them. You need to create a network using Docker, which connects them with each other. 1. To set up a network go to the 0chain directory ``` cd 0chain ``` 2. Run the setup network script ``` docker.local/bin/setup.network.sh ``` On successful Setup, you will receive a network ID in response : ``` d9c238b3f21899137c905b13a4c52fbcab46bee4527d0b6525031c3401b4d329 ``` ### Start the 0dns container To connect to the test network we just created and to fetch all the magic blocks. Run the 0dns container. 1.Navigate to `0dns` directory ``` cd 0dns ``` 2.Run the start script as (sudo or root) using the command. ``` ./docker.local/bin/start.sh ``` This should be a response after a successful start: ``` Starting 0dns ... [+] Running 1/1 ⠿ Container 0dns-0dns-1 Started ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs-old.zus.network/guides/setup-a-blockchain/step-2-setup-the-network-for-0chain-components.md?ask= ``` The question should be specific, self-contained, and written in natural language.
