### About Aquarius
Aquarius is an off-chain component with caches the asset metadata published on-chain. By deploying own Aquarius, developers can control which assets are visible in their marketplace. For example, having a custom Aquarius instance allows assets only from specific addresses to be visible on the marketplace. This tutorial will provide the steps to deploy Aquarius. Ocean Protocol provides Aquarius docker images which can be viewed [here](https://hub.docker.com/r/oceanprotocol/aquarius/tags). Visit [this](https://github.com/oceanprotocol/aquarius) page to view Aquarius source code.
Aquarius is an off-chain component that caches the asset's metadata published on-chain. By deploying their own instance of Aquarius, developers can control which assets are visible in their DApp. For example, having a custom Aquarius instance allows only the assets from specific addresses to be visible in the DApp.
Aquarius consists of two parts:\
\- **API:** The Aquarius API offers a convenient way to access the medatata without scanning the chain yourself.\
\- **Event monitor:** Aquarius continually monitors the chains for MetadataCreated and MetadataUpdated events, processes these events and adds them to the database.

Aquarius consists of two parts:
* **API:** The Aquarius API provides a user with a convenient way to access the metadata without scanning the chain itself.
* **Event monitor:** Aquarius continually monitors the chains for MetadataCreated and MetadataUpdated events, processes these events, and adds them to the database.
As mentioned in the [Setup a Server](setup-server.md) document, all Ocean components can be deployed in two configurations: simple, based on Docker Engine and Docker Compose, and complex, based on Kubernetes with Docker Engine. This document will present how to deploy Provider in each of these configurations.
## Deploying Aquarius using Docker Engine and Docker Compose
This guide will deploy Aquarius, including Elasticsearch as a single systemd service.
### Prerequisites
* A server for hosting Aquarius. See [this guide](setup-server.md) on creating a server.
* Docker and Docker compose are installed. Click [here](https://docs.docker.com/engine/install/) to view guide on installing docker.
* [Obtain an API key](http://localhost:5000/o/mTcjMqA4ylf55anucjH8/s/zQlpIJEeu8x5yl0OLuXn/)
* A server for hosting Aquarius. See [this guide](setup-server.md) for how to create a server;
* Docker Compose and Docker Engine are installed and configured on the server. See [this guide](setup-server.md#install-docker-engine-and-docker-compose) for how to install these products.
* The RPC URLs and API keys for each of the networks to which the Aquarius will be connected. See[ this guide](https://app.gitbook.com/o/mTcjMqA4ylf55anucjH8/s/BTXXhmDGzR0Xgj13fyfM/\~/changes/548/developers/obtaining-api-keys-for-blockchain-access) for how to obtain the URL and the API key.
### Create a working directory
### Steps
```
mkdir Aquarius
cd Aquarius
```
### Create a \`.env\` file
Copy the below content into the \`.env\` file and edit the values as needed.
#### 1. Create the /etc/docker/compose/aquarius/docker-compose.yml file
{% code title=".env" %}
```
# check the available versions: https://hub.docker.com/repository/docker/oceanprotocol/aquarius
AQUARIUS_VERSION=latest
ALLOWED_PUBLISHERS='[""]'
# Elastic search credentials
DB_USERNAME=username
DB_PASSWORD=password
From a terminal console, create /etc/docker/compose/aquarius/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. The following example is for deploying Aquarius for Goerli network. 
# Replace below value with the API provider of your choice
EVENTS_RPC_POLYGON=<polygon-key>
EVENTS_RPC_MAINNET=<mainnet-key>
```
{% endcode %}
For each other network in which you want to deploy Aquarius, add to the file a section similar to "aquarius-events-goerli" included in this example and update the corresponding parameters (i.e. EVENTS\_RPC, OCEAN\_ADDRESS, SUBGRAPH\_URLS) specific to that network. \

```
#### 7. Use Docker CLI to check the Aquarius service's logs
If needed, use docker CLI to check Aquarius' service logs.
First, identify the container id:
```bash
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
355baee34d50 oceanprotocol/aquarius:v5.1.2 "/aquarius/docker-en…" About a minute ago Up About a minute 5000/tcp aquarius-events-goerli
f1f97d6f146f oceanprotocol/aquarius:v5.1.2 "/aquarius/docker-en…" About a minute ago Up About a minute 0.0.0.0:5000->5000/tcp, :::5000->5000/tcp aquarius
a93d989293ac elasticsearch:8.7.0 "/bin/tini -- /usr/l…" About a minute ago Up About a minute 0.0.0.0:9200->9200/tcp, :::9200->9200/tcp, 9300/tcp elasticsearch
```
Then, check the logs from the Aqauarius' Docker containers:
```bash
$ docker logs aquarius [--follow]
$ docker logs aquarius-events-goerli [--follow]
```
## Deploying Aquarius using Kubernetes with Docker Engine
Aquarius depends on the backend database and in this example we will deploy the following resources:
* Elasticsearch.
* Aquarius ([Deployment](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/))
Templates (yaml files) are provided and could be customized based on the environment's specifics.
### Prerequisites
* A server for hosting Aquarius. See [this guide](setup-server.md) for how to create a server;
* Kubernetes with Docker Engine is installed and configured on the server. See [this chapter](setup-server.md#install-kubernetes-with-docker-engine) for information on installing Kubernetes.
* The RPC URLs and API keys for each of the networks to which the Aquarius will be connected. See[ this guide](https://app.gitbook.com/o/mTcjMqA4ylf55anucjH8/s/BTXXhmDGzR0Xgj13fyfM/\~/changes/548/developers/obtaining-api-keys-for-blockchain-access) for how to obtain the URL and the API key.
### Steps
1. [Deploy Elasticsearch service](deploying-aquarius.md#1.-deploy-elasticsearch)
2. [Deploy Aquarius service](deploying-aquarius.md#2.-deploy-aquarius)
#### 1. Deploy Elasticsearch
It is recommended to deploy Elasticsearch through Helm [chart](https://github.com/elastic/cloud-on-k8s).
a. Once the Elasticsearch pods are running, the database service should be available:
```bash
$ kubectl port-forward --namespace ocean svc/elasticsearch-master 9200:9200
Forwarding from 127.0.0.1:9200 -> 9200
Forwarding from [::1]:9200 -> 9200
```
b. Check that the Elasticsearch service is accessible:
```
$ curl localhost:9200
{
"name" : "elasticsearch-master-2",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "KMAfL5tVSJWFfmCOklT0qg",
"version" : {
"number" : "8.5.2",
"build_flavor" : "default",
"build_type" : "docker",
"build_hash" : "a846182fa16b4ebfcc89aa3c11a11fd5adf3de04",
"build_date" : "2022-11-17T18:56:17.538630285Z",
"build_snapshot" : false,
"lucene_version" : "9.4.1",
"minimum_wire_compatibility_version" : "7.17.0",
"minimum_index_compatibility_version" : "7.0.0"
},
"tagline" : "You Know, for Search"
}
```
#### 2. Deploy Aquarius
Aquarius supports indexing multiple chains using a single instance to serve API requests and one instance for each chain that must be indexed.

The following deployment templates could be used for guidance. Some parameters are [optional](https://github.com/oceanprotocol/aquarius) and the template could be adjusted based on these considerations. Common cases are the deployments for one/multiple multiple Ethereum networks:
* Mainnet
* Goerli
* Mumbai
a. Create a YAML file for Aquarius configuration.
The following templates (annotated) could be edited and used for deployment.
* [_aquarius-deployment.yaml_](https://github.com/oceanprotocol/aquarius/blob/update-deploy-docs/deployment/aquarius-deployment.yaml) (annotated): this deployment is responsible for serving API requests

Tip: before deployment you can [validate](https://github.com/instrumenta/kubeval) the yaml file.
b. Deploy the configuration
Deploy the configuration in Kubernetes using the following commands.
```bash
$ kubectl apply -f aquarius-deployment.yaml
$ kubectl apply -f aquarius-events-rinkeby-deployment.yaml
kubectl get pods -l app=aquarius
NAME READY STATUS RESTARTS AGE
aquarius-6fd9cc975b-fxr4d 1/1 Running 0 1d
kubectl get pods -l app=aquarius-events-mumbai
NAME READY STATUS RESTARTS AGE
aquarius-events-mumbai-8748976c4-mh24n 1/1 Running 0 1d
```
Check the logs for newly deployed Aquarius by running the following command:
```bash
$ kubectl logs aquarius-6fd9cc975b-fxr4d [--follow]
$ kubectl logs aquarius-events-mumbai-8748976c4-mh24n [--follow]
```
c. Create a Kubernetes service
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](https://kubernetes.io/docs/concepts/services-networking/service/) for details on how to create a Kubernetes service.
