# Deploying Provider
|
|
|
|
### About Provider
|
|
|
|
Provider encrypts the URL and metadata during publish and decrypts the URL when the dataset is downloaded or a compute job is started. It enables the access to data assets by streaming data (and never the URL). It performs checks on chain for buyer permissions and payments. It also Provides compute services (connects to C2D environment). The source code of Provider can be access from [here](https://github.com/oceanprotocol/provider).
|
|
|
|
### Prerequisites
|
|
|
|
* Docker and Docker compose are installed. Click [here](https://docs.docker.com/engine/install/) to view guide on installing docker.
|
|
* [Obtain an API key](../using-ocean-libraries/configuration.md#obtaining-api-key-for-ethereum-node-provider)
|
|
|
|
### Create a working directory
|
|
|
|
```
|
|
mkdir Provider
|
|
cd Provider
|
|
```
|
|
|
|
### Create a \`.env\` file
|
|
|
|
Copy the below content into the \`.env\` file and edit the values as needed.
|
|
|
|
{% code title=".env" %}
|
|
```
|
|
# Mandatory variables
|
|
|
|
# Update the value to the appropriate tag from here: https://hub.docker.com/r/oceanprotocol/provider-py/tags
|
|
PROVIDER_VERSION=latest
|
|
PROVIDER_PRIVATE_KEY=<private-key>
|
|
NETWORK_URL=<api-key>
|
|
AQUARIUS_URL=<aquarius-url>
|
|
```
|
|
{% endcode %}
|
|
|
|
### Create docker-compose file
|
|
|
|
{% hint style="info" %}
|
|
Set the value of OCEAN\_PROVIDER\_WORKERS to 2 or more to avoid a race condition when provider checks whether it should call a remote provider or not.
|
|
{% endhint %}
|
|
|
|
{% code title="docker-compose.provider.yml" %}
|
|
```yaml
