Deploying Provider
Provider encrypts the URL and metadata during publishing and decrypts the URL when the dataset is downloaded or a compute job is started. It enables access to the 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 a C2D environment).
Provider is a multichain component, meaning that it can handle these tasks on multiple chains with the proper configurations. The source code of Provider can be accessed from here.
As mentioned in the Setup a Server document, all Ocean components can be deployed in two types of configurations: simple, based on Docker Engine and Docker Compose, and complex, based on Kubernetes with Docker Engine. In this document, we will present how to deploy Provider in each of these configurations.
In this guide, we will deploy Provider for two chains: Goerli (Ethereum test network) and Mumbai (Polygon test network). Therefore, please note that in the following configuration files, "5" and "80001" are the chain IDs for Goerli and Mumbai respectively.
- Docker Compose and Docker Engine are installed and configured on the server. See this guide for how to install these products.
- The RPC URLs and API keys for each of the networks to which the Provider will be connected. See this guide for how to obtain the URL and the API key.
- The private key which will be used by Provider to encrypt/decrypt URLs.
The steps to deploy the Provider using Docker Engine and Docker Compose are:
From a terminal console, create /etc/docker/compose/provider/docker-compose.yml file, then copy and paste the following content to it. Check the comments in the file and replace the fields with the specific values of your implementation.
version: '3'
services:

image: oceanprotocol/provider-py:latest =>(check on https://hub.docker.com/r/oceanprotocol/provider-py for specific tag)

2. Create the /etc/systemd/system/[email protected] file
Create the /etc/systemd/system/[email protected] file then copy and paste the following content to it. This example file could be customized if needed.
[Unit]

Requires=docker.service
After=docker.service

ExecStop=/usr/bin/env docker-compose -p $PROJECT stop
[Install]
WantedBy=multi-user.target
Run the following command to reload the systemd manager configuration
sudo systemctl daemon-reload
Optionally, you can enable the services to start at boot, using the following command:
sudo systemctl enable [email protected]
To start the Provider service, run the following command:
sudo systemctl start [email protected]
Check the status of the service by running the following command. The output of the command should be similar to the one presented here.
$ sudo systemctl status [email protected]

If needed, use docker CLI to check provider service logs.
First, identify the container id:
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

Then, check the logs from the Provider's docker container:
$ docker logs --follow provider

In this example, we will run Provider as a Kubernetes deployment resource. We will deploy Provider for two chains: Goerli (Ethereum test network) and Mumbai (Polygon test network). Therefore, please note that in the following configuration files, "5" and "80001" are the chain IDs for Goerli and Mumbai respectively.
- Kubernetes with Docker Engine is installed and configured on the server. See this chapter for information on installing Kubernetes.
- The RPC URLs and API keys for each of the networks to which the Provider will be connected. See this guide for how to obtain the URL and the API key.
- The private key that will be used by Provider to encrypt/decrypt URLs.
- Aquarius is up and running
The steps to deploy the Provider in Kubernetes are:
From a terminal window, create a YAML file (in our example the file is named provider-deploy.yaml) then copy and paste the following content. Check the comments in the file and replace the fields with the specific values of your implementation (RPC URLs, the private key etc.).

Deploy the configuration in Kubernetes using the following commands.
kubectl config set-context --current --namespace ocean
kubectl apply -f provider-deploy.yaml
deployment.apps/provider created
kubectl get pod -l app=provider
NAME READY STATUS RESTARTS AGE
provider-865cb8cf9d-r9xm4 1/1 Running 0 67s
The next step is to create a Kubernetes service (eg. ClusterIP, NodePort, Loadbalancer, ExternalName) for this deployment, depending on the environment specifications. Follow this link for details on how to create a Kubernetes service.
