|

### 1. Create a configuration file using template JSON
|
||||
### **1. Prepare a Python virtual environment**
|
||||
|
||||
In this step, we’ll create a Python virtual environment. Using a virtual environment enables us to avoid conflicts with other Python installations and packages on your host system.
|
||||
|
||||
In a later step, you will install the Python module for this connector and its dependencies in this virtual environment.
|
||||
|
||||
#### **1.1 Create a directory for openmetadata**
|
||||
|
||||
Throughout the docs, we use a consistent directory structure for OpenMetadata services and connector installation. If you have not already done so by following another guide, please create an openmetadata directory now and change into that directory in your command line environment.
|
||||
|
||||
```
|
||||
mkdir openmetadata; cd openmetadata
|
||||
```
|
||||
|
||||
#### **1.2 Create a virtual environment**
|
||||
|
||||
Run the following command to create a Python virtual environment called, `env`. You can try multiple connectors in the same virtual environment.
|
||||
|
||||
```
|
||||
python3 -m venv env
|
||||
```
|
||||
|
||||
#### **1.3 Activate the virtual environment**
|
||||
|
||||
Run the following command to activate the virtual environment.
|
||||
|
||||
```
|
||||
source env/bin/activate
|
||||
```
|
||||
|
||||
Once activated, you should see your command prompt change to indicate that your commands will now be executed in the environment named `env`.
|
||||
|
||||
#### **1.4 Upgrade pip and setuptools to the latest versions**
|
||||
|
||||
Ensure that you have the latest version of pip by running the following command. If you have followed the steps above, this will upgrade pip in your virtual environment.
|
||||
|
||||
```javascript
|
||||
pip3 install --upgrade pip setuptools
|
||||
```
|
||||
|
||||
****
|
||||
|
||||
### **2. Install the Python module for this connector**
|
||||
|
||||
Once the virtual environment is set up and activated as described in Step 1, run the following command to install the Python module for this connector.
|
||||
|
||||
```javascript
|
||||
pip3 install 'openmetadata-ingestion[snowflake]'
|
||||
```
|
||||
|
||||
|
||||
|
||||
### 3. Create a configuration file using template JSON
|
||||
|
||||
Create a new file called `snowflake.json` in the current directory. Note that the current directory should be the `openmetadata` directory.
