Deployment/Installation

Requirements

Hardware requirements:

Minimum Hardware Requirements Recomended Hardware Requirements
4 CPU cores 8 CPU cores
8 GB RAM 16 GB RAM
20 GB storage 40 GB storage

Software Requirements:

  • Docker (Docker Compose installation)
  • Kubernetes (Kubernetes installation - experimental)

Preparing the environment

See the Kubernetes section, if you would like to deploy OpenSlice in a Kubernetes cluster.

1. Backup your previous database if necessary:

sudo docker exec amysql /usr/bin/mysqldump -u root --password=letmein ostmfdb > backup_ostmfdb.sql

2. Install docker

Since July 2023 Docker Compose V1 stopped receiving updates. OpenSlice fully reverted to Compose V2, which is integrated in the Docker installation.

3. Configure containers to properly resolve the DNS of your domain (optional)

sudo nano /etc/docker/daemon.json

and add:

{ 
  "dns": ["8.8.8.8", "8.8.4.4"]
}

After editing daemon.json restart docker daemon for the changes to take place

sudo systemctl restart docker

Downloading the project

1. Create a new folder to download the project

mkdir openslice
cd openslice

2. Download the deployment script

Download the deployment / environment preparation script

wget https://labs.etsi.org/rep/osl/code/org.etsi.osl.main/-/raw/develop/compose/deploy.sh

Make it executable

sudo chmod +x deploy.sh

3. Run the deployment script

OpenSlice is a multi repo project. This script selects the same branch for all repositories of the project to pull from.

After that it builds the respective jar files locally and installs all the npm packages needed for the UI.

If you run the script without selecting a branch the the main branch is going to be selected.

We recommend:

  • main branch for the most stable experience and
  • develop branch for an experience with the latest features (for develop branch installation, it is strongly advisable that you may as well follow the develop documentation)
sudo ./deploy.sh develop #[or replace main with other branch name]

We recommend running the deploy.sh script with root permissions! In other case, some directories may not be accessible by the project building tools and hinder the smooth installation.

Configure docker-compose services

1. Create configuration specific Docker Compose file from the template

cd org.etsi.osl.main/compose/
sudo cp docker-compose.yaml.configure docker-compose.yaml

2. Configure mysql-portal container (optional)

  1. In folder org.etsi.osl.main/compose/mysql-init edit the file 01-databases.sql.
  2. In the org.etsi.osl.main/compose/docker-compose.yaml edit the credentials of the users that services use to connect to the databases, if you wish.
    • portaluser (default is 12345) and
    • keycloak (default is password)

3. Configure keycloak container (optional)

  1. If you made changes to keycloak's mysql credentials:

    In folder org.etsi.osl.main/compose/ edit the file docker-compose.yaml.

DB_DATABASE: keycloak
DB_USER: keycloak
DB_PASSWORD: password
  1. If you want to change the keycloak admin password:

    In folder org.etsi.osl.main/compose/ edit the file docker-compose.yaml

KEYCLOAK_PASSWORD: Pa55w0rd

4. Configure bugzilla container (optional)

If you want to utilise the Bugzilla connector:

In folder org.etsi.osl.main/compose/ edit the file docker-compose.yaml

SPRING_APPLICATION_JSON: '{
  "spring.activemq.brokerUrl": "tcp://anartemis:61616?jms.watchTopicAdvisories=false",
  "spring.activemq.user": "artemis",
  "spring.activemq.password": "artemis",
  "bugzillaurl":"",
  "bugzillakey":"",
  "main_operations_product":""
}'

And add the provided Bugzilla installation information:

"bugzillaurl":"bugzillaurl.xx:443/bugzilla/",
"bugzillakey":"exampleKeyeqNNwxBlgxZgMEIne0Oeq0Bz",
"main_operations_product":"Main Site Operations" // this is the default product to issue tickets

Bugzilla should have the following components under the specified product:

  • NSD Deployment Request: Component used to schedule deployment req
  • Onboarding: Issues related to VNF/NSD Onboarding
  • Operations Support: Default component for operations support
  • Validation: Use to track validation processes of VNFs and NSDs
  • VPN Credentials/Access: Used for requesting VPN Credentials/Access

Also in the 'Main Site Operations' product, a version named 'unspecified' must be created.

5. Configure osportalapi container (NFV services) (conditional)

Change the respective fields:

  • If you made changes to mysql and keycloak credentials.
  • If you want to change logging level (TRACE / DEBUG / INFO / WARN / ERROR).

If you are using a non-local domain, replace everywhere the http://keycloak:8080 with the respective {{protocol://domain.name}}, as well as "spring.portal.main.domain" property.

In folder org.etsi.osl.main/compose/ edit the file docker-compose.yaml

SPRING_APPLICATION_JSON: '{
  "spring.datasource.username":"root",
  "spring.datasource.password":"letmein",
  "spring-addons.issuers[0].uri": "http://keycloak:8080/auth/realms/openslice",
  "spring.security.oauth2.resourceserver.jwt.issuer-uri": "http://keycloak:8080/auth/realms/openslice",
  "springdoc.oAuthFlow.authorizationUrl": "http://keycloak:8080/auth/realms/openslice/protocol/openid-connect/auth",
  "springdoc.oAuthFlow.tokenUrl": "http://keycloak:8080/auth/realms/openslice/protocol/openid-connect/token",  
  "spring.portal.main.domain": "http://localhost",
  "logging.level.org.springframework" : "INFO"
}'

6. osscapi container (TMF API service) (conditional)

Change the respective fields:

  • If you made changes to mysql and keycloak credentials.
  • If you want to change logging level (TRACE / DEBUG / INFO / WARN / ERROR).

If you are using a non-local domain, replace everywhere the http://keycloak:8080 with the respective {{protocol://domain.name}}.

In folder org.etsi.osl.main/compose/ edit the file docker-compose.yaml

SPRING_APPLICATION_JSON: '{
  "spring.datasource.username":"root",
  "spring.datasource.password":"letmein",
  "spring-addons.issuers[0].uri": "http://keycloak:8080/auth/realms/openslice",
  "spring.security.oauth2.resourceserver.jwt.issuer-uri": "http://keycloak:8080/auth/realms/openslice",
  "springdoc.oAuthFlow.authorizationUrl": "http://keycloak:8080/auth/realms/openslice/protocol/openid-connect/auth",
  "springdoc.oAuthFlow.tokenUrl": "http://keycloak:8080/auth/realms/openslice/protocol/openid-connect/token",  
  "logging.level.org.springframework" : "INFO"
}'

Configure nginx

In folder org.etsi.osl.main/compose/nginx create a configuration specific nginx.conf file.

cd org.etsi.osl.main/compose/nginx/
sudo cp nginx.conf.default nginx.conf

If needed, in the nginx.conf file, edit the server_name for an non-local deployment.

Configure Web UI

In folder org.etsi.osl.portal.web/src/js/ create a configuration specific config.js file.

cd org.etsi.osl.portal.web/src/js
sudo cp config.js.default config.js

Edit the config.js file with the information of your domain

{     
  TITLE: "OpenSlice by ETSI",
  WIKI: "https://openslice.readthedocs.io/en/stable/",
  BUGZILLA: "ROOTURL/bugzilla/",
  STATUS: "ROOTURL/status/",
  APIURL: "http://localost:13000",
  WEBURL: "ROOTURL/nfvportal",
  APIOAUTHURL: "ROOTURL/auth/realms/openslice",
  APITMFURL: "ROOTURL/tmf-api/serviceCatalogManagement/v4"
}

Configure TMF Web UI

In the folder org.etsi.osl.tmf.web/src/assets/config there are 3 files available for configuration:

  • config.prod.json (Basic information + API configuration)
  • theming.scss (CSS color palette theming)
  • config.theming.json (HTML configuration - Logo, Favicon, Footer)

The first 2 files above (i.e. config.prod.json, theming.scss) are essential for the successful deployment of OpenSlice, thus created automatically during the initial deployment at org.etsi.osl.tmf.web/src/assets/config directory as a copy of the default ones from the remote repository.

Ensure that you check the config.prod.json and theming.scss files and readjust to your deployment if needed.

# Starting from the root project directory
cd org.etsi.osl.tmf.web/src/assets/config

E.g. Edit "TITLE", "WIKI", etc properties with your domain title. Also configure TMF's API and Keycloak's location for the web application, if needed.

{         
    "TITLE": "OpenSlice by ETSI",
    "PORTALVERSION":"2024-Q2 1.0.0-SNAPSHOT",
    "WIKI": "https://osl.etsi.org/documentation",
    "BUGZILLA": "{BASEURL}/bugzilla/",
    "STATUS": "http://status.localhost/",
    "WEBURL": "{BASEURL}",
    "PORTAL_REPO_APIURL": "{BASEURL}/osapi",
    "ASSURANCE_SERVICE_MGMT_APIURL": "{BASEURL}/oas-api",
    "APITMFURL": "{BASEURL}/tmf-api",
    "OAUTH_CONFIG" : {
        "issuer": "{BASEURL}/auth/realms/openslice",
        "loginUrl": "{BASEURL}/auth/realms/openslice/protocol/openid-connect/auth",
        "tokenEndpoint": "{BASEURL}/auth/realms/openslice/protocol/openid-connect/token",
        "userinfoEndpoint": "{BASEURL}/auth/realms/openslice/protocol/openid-connect/userinfo",
        "redirectUri": "{BASEURL}/redirect",
        "logoutUrl": "{BASEURL}/auth/realms/openslice/protocol/openid-connect/logout", 
        "postLogoutRedirectUri": "{BASEURL}",

        "responseType": "code",
        "oidc": false,
        "clientId": "osapiWebClientId",
        "dummyClientSecret": "secret",

        "requireHttps": false,
        "useHttpBasicAuth": true,
        "clearHashAfterLogin": false,

        "showDebugInformation": true
    }
}

The {BASEURL} placeholder in the file automatically detects the Origin (Protocol://Domain:Port) of the deployment and applies it to every respective property. E.g. If you are attempting a local deployment of Openslice, then {BASEURL} is automatically translated to "http://localhost". Similarly, you may use {BASEURL} to translate to a public deployment configuration, e.g. "https://portal.openslice.io".

If further customization, apart from the default provided, is needed for branding (Logo, Footer) then config.theming.json needs to be created in io.openslice.tmf.web/src/assets/config directory, as follows:

# Starting from the root project directory
cd org.etsi.osl.tmf.web/src/assets/config
sudo cp config.theming.default.json config.theming.json

IMPORTANT NOTE: If you want to apply changes to the JSON configuration files without the need to rebuild the application, you have to apply the changes at the org.etsi.osl.tmf.web/dist/io-openslice-portal-web/assets/config directory. Although, it is mandatory to also apply these changes to the org.etsi.osl.tmf.web/src/assets/config for persistancy, as after any future rebuild of OpenSlice the /dist directory is being overwritten along with its contents. The OpenSlice team strongly recommends to always apply your changes to the TMF web UI configuration files at org.etsi.osl.tmf.web/src/assets/config and rebuild the application.

Deploy OpenSlice via Docker Compose

After configuring the services, and editing the docker compose file accordingly, the docker compose instantiation command can be performed.

# Starting from the root project directory
cd org.etsi.osl.main/compose/
sudo docker compose --profile prod down;sudo docker compose --profile prod up -d --build

Depending on your machine, this process might take time. if for any reason the deployment fails during first time, please rerun the above before any further measures.

Validating deployments and container monitoring

You can monitor containers' status with portainer at port 9000 (http://your-ip:9000).

Initially, you may monitor the local machine at portainer.

Please check that all containers are in running state.

Post installation steps

After the successful deployment of OpenSlice, to ensure the E2E user experience, this section is mandatory. It contains crucial configuration in regard of authentication and user creation.

Configure Keycloak server

The Keycloack server is managing authentication and running on a container at port 8080. It is also proxied to your host via nginx under http://localhost/auth.

  • Navigate to http://domain.com/auth/ or https://domain.com/auth/, (http://ipaddress:8080/auth/ or https://ipaddress:8443/auth/ which are directly accessible without proxy)

  • Navigate to Administration Console

  • Login with the credentials from section Configure keycloak container. Default values are:

    • user: admin and
    • password: KEYCLOAK_PASSWORD

if you are running in HTTP you will get a message: HTTPS required.

To resolve this issue when running in HTTP:

  • Select the master realm from top left corner
  • Go to login Tab and select "Require SSL": None
  • Repeat for realm Openslice

If you are running in HTTPS, then "Require SSL" can be left unchanged to external requests.

1. Configure redirects

Navigate to realm Openslice > client > osapiWebClientId and change the Root URL to your domain.

Also, insert your domain, e.g. http://example.org/*, at: * Valid Redirect URIs * Web Origins

2. Configure email

Keycloak allows new users to register. Subsequently, this will also allow new users to register to the OpenSlice portal.

On Tab Login > check User registration, Verify email, Forgot password etc.

Also, enter the details on Realm > Email > Enable Authentication.

3. Add an OpenSlice admin user

This step is mandatory so as to access the OpenSlice Web UI. To add an OpenSlice admin user you must: - Navigate to manage/users and add an OpenSlice admin user, e.g. username=admin. - Set a password - Navigate to Role Mappings and add ADMIN and MENTOR to Assigned Roles.

That user is different from the Keycloak admin user. It is required to login and browse the OpenSlice Web UI. The Roles ADMIN and MENTOR guarantee full access through the Openslice UI, thus such a user is always required.

Keycloak at localhost

This is an important step if you run Keycloak on localhost!

1 - Edit your Hosts File, adding the line below

127.0.0.1 keycloak

Hosts File Location:

  • In Linux/Unix, the file's location is at /etc/hosts

  • In Windows, its location is at c:\Windows\System32\Drivers\etc\hosts

2 - Replace http://localhost/auth/ with http://keycloak:8080/auth/ in your Keycloak config for AngularJS and Angular (see examples below).

Explanation

Nginx uses the http://keycloak:8080 URL, which is accessible via the internal docker system's network. The Front-end (TS/Angular) shall also use the http://keycloak:8080. This way, you will not get the invalid token error, as the API is acquiring the token from http://keycloak:8080 (internally) and the Front-end is getting verified by an issuer at the same URL, as well.

2.1 - For the Angular configuration (TMF portal UI), navigate to org.etsi.osl.tmf.web/src/assets/config and edit config.prod.json

# Starting from the root project directory
cd org.etsi.osl.tmf.web/src/assets/config
nano config.prod.json

After editing it should look like the example bellow:

{         
  "TITLE": "OpenSlice by ETSI",
  "PORTALVERSION":"2023-Q3 1.2.0-SNAPSHOT",
  "WIKI": "https://openslice.readthedocs.io/en/stable/",
  "BUGZILLA": "{BASEURL}/bugzilla/",
  "STATUS": "http://status.localhost/",
  "WEBURL": "{BASEURL}",
  "PORTAL_REPO_APIURL": "{BASEURL}/osapi",
  "ASSURANCE_SERVICE_MGMT_APIURL": "{BASEURL}/oas-api",
  "APITMFURL": "{BASEURL}/tmf-api",
  "OAUTH_CONFIG" : {
      "issuer": "http://keycloak:8080/auth/realms/openslice",
      "loginUrl": "http://keycloak:8080/auth/realms/openslice/protocol/openid-connect/auth",
      "tokenEndpoint": "http://keycloak:8080/auth/realms/openslice/protocol/openid-connect/token",
      "userinfoEndpoint": "http://keycloak:8080/auth/realms/openslice/protocol/openid-connect/userinfo",
      "redirectUri": "{BASEURL}/redirect",
      "logoutUrl": "http://keycloak:8080/auth/realms/openslice/protocol/openid-connect/logout", 
      "postLogoutRedirectUri": "{BASEURL}",

      "responseType": "code",
      "oidc": false,
      "clientId": "osapiWebClientId",
      "dummyClientSecret": "secret",

      "requireHttps": false,
      "useHttpBasicAuth": true,
        clearHashAfterLogin": false,

      "showDebugInformation": true
  }
}

Note the difference in changing {BASEURL} -> http://keycloak:8080

If you want the changes to take place immediately without rebuilding the project, then repeat the process for org.etsi.osl.tmf.web/dist/org.etsi.osl.tmf.web/assets/config/config.prod.json

2.2 - For the AngularJS configuration (NVF portal UI), navigate to org.etsi.osl.portal.web/src/js and edit config.js

# Starting from the root project directory
cd org.etsi.osl.portal.web/src/js
nano config.js

after editing it should look like the example bellow:

var appConfig = angular.module('portalwebapp.config',[]);


appConfig.factory('APIEndPointService', function() {
   return {       
      TITLE: "OpenSlice by ETSI",
      WIKI: "https://openslice.readthedocs.io/en/stable/",
      BUGZILLA: "ROOTURL/bugzilla/",
      STATUS: "ROOTURL/status/",
      APIURL: "http://localost:13000",
      WEBURL: "ROOTURL/nfvportal",
      APIOAUTHURL: "ROOTURL/auth/realms/openslice",
      APITMFURL: "ROOTURL/tmf-api/serviceCatalogManagement/v4"
   };
});

Note the difference in "APIOAUTHURL" property

NFV Orchestrator Configuration

After successfully deploying and configuring OpenSlice, you may configure its environment (e.g. the NFVO) that will facilitate the deployment of NFV artifacts.

See NFV Orchestrator Configuration.


Kubernetes installation

Openslice can be installed in a Kubernetes cluster.

The related scripts are inside the kubernetes folder. Follow these steps along the lines. You need to configure the ingress properly depending on how you want to expose Openslice.

1 - Create an openslice namespace

kubectl create namespace openslice

2 - Apply or create an ingress. 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. You may need to deploy an Ingress controller such as ingress-nginx.

You can also adapt it to connect to public cloud load balancers depending on your needs.

The following will expose an ingress resource from one of your a k8s nodes on port 80.

 kubectl apply -f openslice-ingress.yaml

Finding the ingress IP:


kubectl describe -f openslice-ingress.yaml


Name:             openslice-ingress
Namespace:        openslice
Address:          10.10.10.35
Default backend:  default-http-backend:80 (<error: endpoints "default-http-backend" not found>)
Rules:
  Host        Path  Backends
  ----        ----  --------
  *
              /services   tmfweb:80 (<error: endpoints "tmfweb" not found>)
              /tmf-api    osscapi:13082 (<error: endpoints "osscapi" not found>)
              /auth       keycloak:8080 (<error: endpoints "keycloak" not found>)
              /osapi      osportalapi:13000 (<error: endpoints "osportalapi" not found>)
              /           portalweb:80 (<error: endpoints "portalweb" not found>)
Annotations:  kubernetes.io/ingress.class: nginx
Events:
  Type    Reason  Age                    From                      Message
  ----    ------  ----                   ----                      -------
  Normal  Sync    9m29s (x2 over 9m58s)  nginx-ingress-controller  Scheduled for sync

From the above example, our exposed ingress is at Address: 10.10.10.35

3 - We need to configure the expose address and deploy openslice (IP or URL e.g. http://myopenslice.xxx)

./k8sdeploy.sh 10.10.10.35

4 - Check the status of Openslice in the cluster. Should be similar to the following:


kubectl get pods --namespace=openslice  -o wide
