# 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.
Modify 0dns.yaml
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
```
