# Partition Service
os-partition-gcp is a [Spring Boot](https://spring.io/projects/spring-boot) service that is responsible for creating and retrieving partition specific properties on behalf of other services whether they are secret values or not.

## Getting Started
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

### Prerequisites
Pre-requisites

* GCloud SDK with java (latest version)
* JDK 8
* Lombok 1.16 or later
* Maven

### Installation
In order to run the service locally or remotely, you will need to have the following environment variables defined.

| name | value | description | sensitive? | source |
| ---  | ---   | ---         | ---        | ---    |
| `LOG_PREFIX` | `service` | Logging prefix | no | - |
| `SERVER_SERVLET_CONTEXPATH` | `/api/partition/v1` | Servlet context path | no | - |
| `AUTHORIZE_API` | ex `https://entitlements.com/entitlements/v1` | Entitlements API endpoint | no | output of infrastructure deployment |
| `GOOGLE_CLOUD_PROJECT` | ex `osdu-cicd-epam` | Google Cloud Project Id| no | output of infrastructure deployment |
| `GOOGLE_AUDIENCES` | ex `*****.apps.googleusercontent.com` | Client ID for getting access to cloud resources | yes | https://console.cloud.google.com/apis/credentials |
| `PARTITION_ADMIN_ACCOUNT` | ex `admin@domen.iam.gserviceaccount.com` | Partition Admin account email | no | - |
| `GOOGLE_APPLICATION_CREDENTIALS` | ex `/path/to/directory/service-key.json` | Service account credentials, you only need this if running locally | yes | https://console.cloud.google.com/iam-admin/serviceaccounts |

### Run Locally
Check that maven is installed:

```bash
$ mvn --version
Apache Maven 3.6.0
Maven home: /usr/share/maven
Java version: 1.8.0_212, vendor: AdoptOpenJDK, runtime: /usr/lib/jvm/jdk8u212-b04/jre
...
```

You may need to configure access to the remote maven repository that holds the OSDU dependencies. This file should live within `~/.mvn/community-maven.settings.xml`:

```bash
$ cat ~/.m2/settings.xml
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <servers>
        <server>
            <id>community-maven-via-private-token</id>
            <!-- Treat this auth token like a password. Do not share it with anyone, including Microsoft support. -->
            <!-- The generated token expires on or before 11/14/2019 -->
             <configuration>
              <httpHeaders>
                  <property>
                      <name>Private-Token</name>
                      <value>${env.COMMUNITY_MAVEN_TOKEN}</value>
                  </property>
              </httpHeaders>
             </configuration>
        </server>
    </servers>
</settings>
```
* Update the Google cloud SDK to the latest version:

```bash
gcloud components update
```
* Set Google Project Id:

```bash
gcloud config set project <YOUR-PROJECT-ID>
```

* Perform a basic authentication in the selected project:

```bash
gcloud auth application-default login
```

* Navigate to partition service's root folder and run:

```bash
mvn clean install   
```

* If you wish to see the coverage report then go to target/site/jacoco/index.html and open index.html

* If you wish to build the project without running tests

```bash
mvn clean install -DskipTests
```

After configuring your environment as specified above, you can follow these steps to build and run the application. These steps should be invoked from the *repository root.*

```bash
cd provider/partition-gcp/ && mvn spring-boot:run
```

## Testing
Navigate to partition service's root folder and run all the tests:

```bash
# build + install integration test core
$ (cd testing/partition-test-core/ && mvn clean install)
```

### Running E2E Tests
This section describes how to run cloud OSDU E2E tests (testing/partition-test-gcp).

You will need to have the following environment variables defined.

| name | value | description | sensitive? | source |
| ---  | ---   | ---         | ---        | ---    |
| `ENVIRONMENT` | ex `dev` |  | no |  |
| `PARTITION_BASE_URL` | ex `http://localhost:8080/` | service base URL | yes |  |
| `CLIENT_TENANT` | ex `opendes` | name of the client partition | yes |  |
| `MY_TENANT` | ex `opendes` | name of the OSDU partition | yes |  |
| `INTEGRATION_TESTER` | `********` | Service account for API calls. Note: this user must be `PARTITION_ADMIN_ACCOUNT` | yes | https://console.cloud.google.com/iam-admin/serviceaccounts |
| `NO_DATA_ACCESS_TESTER` | `********` | Service account base64 encoded string without data access | yes | https://console.cloud.google.com/iam-admin/serviceaccounts |
| `INTEGRATION_TEST_AUDIENCE` | `********` | client application ID | yes | https://console.cloud.google.com/apis/credentials |

Execute following command to build code and run all the integration tests:

```bash
# Note: this assumes that the environment variables for integration tests as outlined
#       above are already exported in your environment.
$ (cd testing/partition-test-gcp/ && mvn clean test)
```

## Deployment
Partition Service is compatible with App Engine Flexible Environment and Cloud Run.

* To deploy into Cloud run, please, use this documentation:
  https://cloud.google.com/run/docs/quickstarts/build-and-deploy

* To deploy into App Engine, please, use this documentation:
  https://cloud.google.com/appengine/docs/flexible/java/quickstart

#### Cloud KMS Setup

Enable cloud KMS on master project

Create king ring and key in the ***master project***

```bash
    gcloud services enable cloudkms.googleapis.com
    export KEYRING_NAME="csqp"
    export CRYPTOKEY_NAME="searchService"
    gcloud kms keyrings create $KEYRING_NAME --location global
    gcloud kms keys create $CRYPTOKEY_NAME --location global \
    		--keyring $KEYRING_NAME \
    		--purpose encryption
```

Add **Cloud KMS CryptoKey Encrypter/Decrypter** role to the **App Engine default service account** of the master project through IAM - Role tab

Add "Cloud KMS Encrypt/Decrypt" role to the "App Engine default service account" of ***master project***
