<h3 id="software-requirements">Software Requirements</h3>
<ul>
<li><strong>git:</strong> For cloning the project repository.</li>
<li><strong>Kubernetes:</strong> A running cluster where OpenSlice will be deployed. <ul>
<li><strong>Disclaimer:</strong> The current manual setup of Persistent Volumes using <code>hostPath</code> is designed to operate with <strong>only a single worker node</strong>. This setup will not support data persistence if a pod is rescheduled to another node.</li>
</ul>
</li>
<li><strong>Helm:</strong> For managing the deployment of OpenSlice.</li>
<li>
<p><strong>Ingress Controller:</strong> Ingress exposes HTTP and HTTPS routes from outside the cluster to services within the cluster. Traffic routing is controlled by rules defined on the Ingress resource. An Ingress may be configured to give Services externally-reachable URLs, load balance traffic, terminate SSL / TLS, and offer name-based virtual hosting. An Ingress controller is responsible for fulfilling the Ingress, usually with a load balancer, though it may also configure your edge router or additional frontends to help handle the traffic. You must have an Ingress controller to satisfy an Ingress.</p>
<ul>
<li><strong>Nginx Ingress Controller (Kubernetes Community Edition):</strong>  The ingress resource is configured to use an Nginx type ingress controller. </li>
<li>If you need to expose the message bus service (Artemis), which communicates using the TCP protocol, you must use version <strong>&gt;= 1.9.13</strong> of the Nginx Ingress Controller (a prerequisite for <a href="#management-of-multiple-kubernetes-clusters">managing multiple kubernetes clusters</a>). This version or higher includes the required functionality to handle TCP services. Otherwise, earlier versions may suffice depending on your configuration.</li>
<li>To install or upgrade to the required version, run the following command:</li>
</ul>
<p><code>bash
  helm upgrade nginx-ingress ingress-nginx/ingress-nginx --namespace ingress \
  --set tcp.61616="&lt;openslice-namespace&gt;/&lt;openslice-helm-release-name&gt;-artemis:61616"</code></p>
<p>Replace <code>&lt;helm-release-name&gt;</code> with the name of your OpenSlice Helm release.
  * More details regarding the Nginx Ingress Controller (Kubernetes Community Edition) can be found <a href="https://kubernetes.github.io/ingress-nginx/deploy/">here</a>.
* <strong>Other Ingress Controller:</strong>  For non-Nginx ingress controllers, modify <code>[repo-root]/kubernetes/helm/openslice/templates/openslice-ingress.yaml</code> to meet your controller’s requirements.</p>
</li>
</ul>
<h3 id="exposure">Exposure</h3>
<h4 id="option-1-load-balancer">Option 1 - Load balancer</h4>
<ul>
<li><strong>Network Load Balancer:</strong> Required for exposing the service (e.g., GCP, AWS, Azure, MetalLB).</li>
<li><strong>Domain/IP Address:</strong> Necessary for accessing the application. This should be configured in <code>[repo-root]/kubernetes/helm/openslice/values.yaml</code> under <code>rooturl</code>.</li>
</ul>
<h4 id="option-2-ingress">Option 2 - Ingress</h4>
<ul>
<li><strong>Ingress Controller with NodePort:</strong> You can expose the application using the NodePort of the Ingress Controller's service.</li>
<li><strong>IP Address and Port:</strong> Use the IP address of the <strong>master node</strong> and the assigned NodePort to access the application. This should be configured in <code>[repo-root]/kubernetes/helm/openslice/values.yaml</code> under <code>rooturl</code>.</li>
</ul>
<p>For example:</p>
<pre><code>rooturl: http://&lt;master-node-ip&gt;:&lt;nodeport&gt;
</code></pre>
<h3 id="additional-configuration">Additional Configuration</h3>
<ul>
<li><strong>Storage Class:</strong> In a production environment, specify your <code>storageClass</code> in <code>[repo-root]/kubernetes/helm/openslice/values.yaml</code> under <code>storageClass</code>. If not defined, PVs will be created and managed manually.<ul>
<li><strong>Disclaimer:</strong> Before deploying, confirm that your storage system supports claims of one 10G and two 1G volumes.</li>
</ul>
</li>
</ul>
<h2 id="preparing-the-environment">Preparing the environment</h2>
<h3 id="1-setting-up-a-kubernetes-cluster">1. Setting Up A Kubernetes Cluster</h3>
<p>Refer to the official Kubernetes documentation for setting up a cluster. Ensure your cluster meets the hardware requirements specified above.</p>
<h3 id="2-installing-helm">2. Installing Helm</h3>
<p>Helm must be installed on your machine to deploy OpenSlice via Helm charts. Follow the <a href="https://helm.sh/docs/intro/install/">official Helm installation guide</a>.</p>
<h2 id="downloading-the-project">Downloading the project</h2>
<h3 id="1-create-a-new-folder-to-download-the-project">1. Create a new folder to download the project</h3>
<pre><code class="language-bash">mkdir openslice
cd openslice
</code></pre>
<h3 id="2-download-the-project-code">2. Download the project code</h3>
<p>Clone the project code from the GitLab repository. 
<strong>Note:</strong> This process will be simplified once the charts are published in the GitLab registry, requiring only the chart to be pulled.</p>
<pre><code class="language-bash">git clone https://labs.etsi.org/rep/osl/code/org.etsi.osl.main.git
cd org.etsi.osl.main/kubernetes/helm/openslice/
</code></pre>
<h3 id="3-prerequisites-before-deployment">3. Prerequisites before deployment</h3>
<p>Before deploying the Helm chart, ensure you have configured the necessary components as detailed in the following section, i.e. <a href="#configure-helm-chart-services">Configure Helm Chart Services</a>. By default, the <code>main</code> branch is selected for deployment.</p>
<p>We recommend:</p>
<ul>
<li>main branch for the most stable experience and</li>
<li>develop branch for an experience with the latest features (for develop branch installation, it is strongly advisable that you may as well follow the <a href="https://osl.etsi.org/documentation/develop/deployment/">develop documentation</a>)</li>
</ul>
<h2 id="configure-helm-chart">Configure Helm Chart</h2>
<p>When deploying OpenSlice with Helm, service configurations are handled through the <code>values.yaml</code> file. This file allows you to define all necessary configurations for your deployment, including database credentials, service URLs, and logging levels. Below are examples of how to configure your services in Helm based on your provided values.</p>
<h3 id="configuring-services">Configuring Services</h3>
<h4 id="1-database-configuration">1. Database Configuration</h4>
<p>To configure MySQL and other related services, you can directly set the values in your <code>values.yaml</code> file under the <code>oscreds</code> and <code>mysql</code> sections. For example:</p>
<pre><code class="language-yaml">oscreds:
  mysql:
    username: &quot;root&quot;
    password: &quot;letmein&quot;
    openslicedb: &quot;osdb&quot;
    keycloak: 
      database: &quot;keycloak&quot;
      username: &quot;keycloak&quot;
      password: &quot;password&quot;
      adminpassword: &quot;Pa55w0rd&quot;
    portal:
      database: &quot;osdb&quot;
      username: &quot;portaluser&quot;
      password: &quot;12345&quot;
</code></pre>
<h4 id="2-keycloak-configuration">2. Keycloak Configuration</h4>
<p>Keycloak settings, including the database and admin password, are part of the <code>oscreds.mysql.keycloak</code> section. If you need to adjust Keycloak-specific settings like realms or client configurations, you'll likely need to customize your Helm chart further or manage these settings directly within Keycloak after deployment. The Keycloak realm configuration that is imported by default can be found under <code>kubernetes/helm/openslice/files/keycloak-init/realm-export.json</code>.</p>
<pre><code class="language-yaml">oscreds:
  mysql:
    keycloak: 
      database: &quot;keycloak&quot;
      username: &quot;keycloak&quot;
      password: &quot;password&quot;
      adminpassword: &quot;Pa55w0rd&quot;
</code></pre>
<h4 id="3-cridge-configuration">3. CRIDGE Configuration</h4>
<p>To create and manage Kubernetes Custom Resources (CRs), you have to install and configure the CRIDGE component. </p>
<p>For CRIDGE to work properly, you need to provide a <strong>cluster-wide scope kubeconfig</strong> file (typically located at <code>/home/{user}/.kube</code> directory of the Kubernetes Cluster's host). This kubeconfig file allows CRIDGE to communicate with your Kubernetes cluster.</p>
<p>There are two ways to install CRIDGE:</p>
<h5 id="31-bundled-cridge-deployment-with-the-openslice-helm-chart-same-cluster-environment">3.1 <strong>Bundled CRIDGE deployment with the OpenSlice Helm chart (same cluster environment)</strong></h5>
<p>By default, the OpenSlice Helm chart also deploys CRIDGE alongside the bundle. To configure CRIDGE, there are three different ways to provide this kubeconfig file during deployment:</p>
<ol>
<li>
<p><strong>Manual Copy to Helm Files Directory</strong>:</p>
<ul>
<li>Copy the kubeconfig file to the following directory:<br />
<code>org.etsi.osl.main/kubernetes/helm/openslice/files/org.etsi.osl.cridge</code>.</li>
<li>The deployment process will automatically copy the file into the <code>/root/.kube</code> directory of the CRIDGE container.</li>
<li><strong>Note:</strong> This method expects the kubeconfig file to be named exactly <code>kubeconfig.yaml</code> in the specified directory.</li>
</ul>
</li>
<li>
<p><strong>Passing the Kubeconfig File Using Helm (<code>--set-file</code>)</strong>:</p>
<ul>
<li>If you do not wish to manually copy the file, you can pass it directly during the Helm installation using the <code>--set-file</code> option, at the final <a href="#deploy-the-helm-chart">deployment process</a>:</li>
</ul>
<p><code>bash
--set-file cridge.kubeconfig.raw=path/to/kubeconfig.yaml</code></p>
<ul>
<li>This method reads the specified kubeconfig file and mounts it into the CRIDGE container during deployment.</li>
</ul>
</li>
<li>
<p><strong>Passing a Base64-Encoded Kubeconfig Using Helm (<code>--set</code>)</strong>:</p>
<ul>
<li>Alternatively, you can pass the kubeconfig as a base64-encoded string, during the Helm installation using the <code>--set</code> option, at the final <a href="#deploy-the-helm-chart">deployment process</a>:</li>
</ul>
<p><code>bash
--set cridge.kubeconfig.base64="$(base64 path/to/kubeconfig.yaml)"</code></p>
<ul>
<li>This method encodes the kubeconfig content and passes it directly to the CRIDGE container.</li>
</ul>
</li>
</ol>
<blockquote>
<p><strong>Note:</strong> Regardless of the method you choose, if you're using a non-standard kubeconfig file name, make sure to adjust the references or rename the file as needed.</p>
</blockquote>
<h5 id="32-standalone-cridge-deployment">3.2 <strong>Standalone CRIDGE deployment</strong></h5>
<p>There can be cases where a separate deployment of CRIDGE, apart from the bundled OpenSlice deployment, may be needed. These cases comprise:</p>
<ul>
<li>remote cluster management, different from the one OpenSlice is installed</li>
<li>more control over the component (e.g. multiple component instances / clusters)</li>
</ul>
<p>In this case, initially you have to disable CRIDGE from deploying with the rest of OpenSlice. To do so, in the <code>values.yaml</code> of OpenSlice Helm chart, you have to change the <code>cridge.enabled</code> flag to <code>false</code>.</p>
<pre><code class="language-yaml">cridge:
  enabled: false
</code></pre>
<p>Following, clone the CRIDGE project from the GitLab, which also includes the respective standalone Helm chart.</p>
<pre><code class="language-bash">git clone https://labs.etsi.org/rep/osl/code/org.etsi.osl.cridge.git
cd org.etsi.osl.cridge/helm/cridge/
</code></pre>
<p>Similarly, to configure CRIDGE, there are three different ways to provide this kubeconfig file during deployment:</p>
<ol>
<li>
<p><strong>Manual Copy to Helm Files Directory</strong>:</p>
<ul>
<li>Copy the kubeconfig file to the following directory:<br />
<code>org.etsi.osl.cridge/helm/cridge/files/org.etsi.osl.cridge</code>.</li>
<li>The deployment process will automatically copy the file into the <code>/root/.kube</code> directory of the CRIDGE container.</li>
<li><strong>Note:</strong> This method expects the kubeconfig file to be named exactly <code>kubeconfig.yaml</code> in the specified directory.</li>
</ul>
</li>
<li>
<p><strong>Passing the Kubeconfig File Using Helm (<code>--set-file</code>)</strong>:</p>
<ul>
<li>If you do not wish to manually copy the file, you can pass it directly during the Helm installation using the <code>--set-file</code> option:</li>
</ul>
<p><code>bash
helm install cridge-release . --set-file kubeconfig.raw=path/to/kubeconfig.yaml</code></p>
<ul>
<li>This method reads the specified kubeconfig file and mounts it into the CRIDGE container during deployment.</li>
</ul>
</li>
<li>
<p><strong>Passing a Base64-Encoded Kubeconfig Using Helm (<code>--set</code>)</strong>:</p>
<ul>
<li>Alternatively, you can pass the kubeconfig as a base64-encoded string:</li>
</ul>
<p><code>bash
helm install cridge-release . --set kubeconfig.base64="$(base64 path/to/kubeconfig.yaml)"</code></p>
<ul>
<li>This method encodes the kubeconfig content and passes it directly to the CRIDGE container.</li>
</ul>
</li>
</ol>
<blockquote>
<p><strong>Note:</strong> Regardless of the method you choose, if you're using a non-standard kubeconfig file name, make sure to adjust the references or rename the file as needed.</p>
<p><strong>Important Note:</strong> If you are deploying CRIDGE in the same cluster and namespace as OpenSlice, no additional configuration is required for the message bus broker URL and OpenSlice communicates with CRIDGE directly. However, if CRIDGE is installed in a <strong>separate Kubernetes cluster</strong> from the one hosting OpenSlice, it is important to configure the <code>values.yaml</code> file for the CRIDGE Helm chart to point to the correct message bus broker URL. Please see <a href="#software-requirements">Nginx Ingress Controller (Kubernetes Community Edition) configuration</a> on how to properly expose the message bus in such scenario.</p>
</blockquote>
<p>In the <code>values.yaml</code> of the CRIDGE Helm chart, you must set <code>oscreds.activemq.brokerUrl</code> to point to the IP address of the ingress controller in the OpenSlice cluster, as shown below:</p>
<pre><code class="language-yaml">oscreds:
  activemq:
    brokerUrl: &quot;tcp://&lt;openslice-rootURL&gt;:61616?jms.watchTopicAdvisories=false&quot;
</code></pre>
<h5 id="management-of-multiple-kubernetes-clusters">Management of multiple Kubernetes Clusters</h5>
<p>OpenSlice also offers management support of <em>multiple Kubernetes Clusters</em> simultaneously. </p>
<p>For this, you will have to replicate the steps in <a href="#32-standalone-cridge-deployment">Standalone CRIDGE deployment</a> for every Cluster. Each CRIDGE instance will be in charged with the management of one Kubernetes Cluster.</p>
<h4 id="4-external-services-configuration">4. External Services Configuration</h4>
<p>For configuring optional external services like Bugzilla and CentralLog, specify their URLs and credentials in the <code>values.yaml</code> file:</p>
<pre><code class="language-yaml">bugzillaurl: &quot;example.com:443/bugzilla&quot;
bugzillakey: &quot;VH2Vw0iI5aYgALFFzVDWqhACwt6Hu3bXla9kSC1Z&quot;
main_operations_product: &quot;Main Site Operations&quot; // this is the default product to issue tickets
centrallogurl: &quot;http://elk_ip:elk_port/index_name/_doc&quot;
</code></pre>
<p>Bugzilla should have the following components under the specified product:  </p>
<ul>
<li>NSD Deployment Request: Component used to schedule deployment req  </li>
<li>Onboarding: Issues related to VNF/NSD Onboarding  </li>
<li>Operations Support: Default component for operations support  </li>
<li>Validation: Use to track validation processes of VNFs and NSDs  </li>
<li>VPN Credentials/Access: Used for requesting VPN Credentials/Access   </li>
</ul>
<p>Also in the 'Main Site Operations' product, a version named 'unspecified' must be created.</p>
<h4 id="5-application-and-logging-configuration">5. Application and Logging Configuration</h4>
<p>Application-specific configurations, such as OAuth client secrets, can be set in the <code>spring</code> section:</p>
<pre><code class="language-yaml">spring:
  oauthClientSecret: &quot;secret&quot;
</code></pre>
<h4 id="6-ingress-and-root-url">6. Ingress and Root URL</h4>
<p>To configure the ingress controller and root URL for OpenSlice, update the rooturl field with your ingress load balancer IP or domain. This setting is crucial for external access to your application:</p>
<pre><code class="language-yaml">rooturl: &quot;http://openslice.com&quot; # Example domain
# or
rooturl: &quot;http://3.15.198.35:8080&quot; # Example IP with port
</code></pre>
<h4 id="7-persistent-volume-for-mysql">7. Persistent Volume for MySQL</h4>
<p>For persistent storage, especially for MySQL, define the storage size under the <code>mysql</code> section. This ensures that your database retains data across pod restarts and deployments.</p>
<pre><code class="language-yaml">mysql:
  storage: &quot;10Gi&quot;
</code></pre>
<h4 id="8-configuring-tcp-forwarding-for-artemis">8. Configuring TCP Forwarding for Artemis</h4>
<p>To expose the message bus service (Artemis) via the ingress controller, it’s essential to configure TCP traffic forwarding. Artemis listens on port <code>61616</code>, and this traffic needs to be directed to the Artemis service within your Kubernetes cluster.</p>
<p>In the <a href="#software-requirements">Ingress Controller Setup</a> section, you already configured the Nginx ingress controller to handle this TCP forwarding. By setting the rule for port <code>61616</code>, traffic arriving at the ingress will be forwarded to the Artemis service defined in your Helm release.</p>
<p>This setup ensures that the message bus service is accessible externally via the ingress controller, completing the necessary configuration for Artemis.</p>
<h3 id="configure-web-ui">Configure Web UI</h3>
<p>In folder <code>kubernetes/helm/openslice/files/org.etsi.osl.portal.web/src/js</code> you must make a copy of <code>config.js.default</code> file and rename it to <code>config.js</code>. </p>
<p>This is <strong>mandatory</strong> for the configuration file to be discoverable.</p>
<p>Edit the <code>config.js</code> configuration file with your static configuration, if needed.</p>
<pre><code>{

<h3 id="configure-tmf-web-ui">Configure TMF Web UI</h3>
<p>In the folder <code>kubernetes/helm/openslice/files/org.etsi.osl.tmf.web/src/assets/config</code> there are 3 files available for configuration:</p>
<ul>
<li>config.prod.default.json (Basic information + API configuration)</li>
<li>theming.default.scss (CSS color palette theming)</li>
<li>config.theming.default.json (HTML configuration - Logo, Favicon, Footer)</li>
</ul>
<p>You must make a copy of files:</p>
<ul>
<li><code>config.prod.default.json</code> and rename it to <code>config.prod.json</code></li>
<li><code>theming.default.scss</code> and rename it to <code>theming.scss</code></li>
</ul>
<p>The 2 files above (i.e. config.prod.json, theming.scss) are essential for the successful deployment of OpenSlice, and executing the above steps is <strong>mandatory</strong> for the configuration files to be discoverable.</p>
<p>Ensure that you check the <code>config.prod.json</code> and <code>theming.scss</code> files and readjust to your deployment if needed.</p>
<pre><code class="language-bash"># Starting from the root project directory
cd kubernetes/helm/openslice/files/org.etsi.osl.tmf.web/src/assets/config
