# Developing

Openslice backend services are mainly implemented with Java 17 or above and Spring boot.

Openslice uses various subsystems and depending on the module would you like to work, other subsystems must be present (you can disable them though in the code, e.g. at application.yml file)

To get the latest development branch:

    wget https://raw.githubusercontent.com/openslice/org.etsi.osl.main/develop/compose/deploy.sh
    sudo ./deploy.sh develop  [or replace develop with other branch name]

- Slack: https://openslice.slack.com

## General subsystems

- Docker and Docker Compose should be installed in your development environment

### Consul

consul service registry should be up and running. You can launch consul with docker: `sudo docker run -d --name consul -p 8500:8500 -p 8600:8600 consul`

### ActiveMQ

ActiveMQ is our messaging system. You can launch an instance of ActiveMQ: `sudo docker run --name='activemq' -d -e 'ACTIVEMQ_NAME=amqp-srv1' -e 'ACTIVEMQ_REMOVE_DEFAULT_ACCOUNT=true' -e 'ACTIVEMQ_ADMIN_LOGIN=admin' -e 'ACTIVEMQ_ADMIN_PASSWORD=admin' -e 'ACTIVEMQ_WRITE_LOGIN=producer_login' -e 'ACTIVEMQ_WRITE_PASSWORD=producer_password' -e 'ACTIVEMQ_READ_LOGIN=consumer_login' -e 'ACTIVEMQ_READ_PASSWORD=consumer_password' -e 'ACTIVEMQ_JMX_LOGIN=jmx_login' -e 'ACTIVEMQ_JMX_PASSWORD=jmx_password' -e 'ACTIVEMQ_STATIC_TOPICS=topic1;topic2;topic3' -e 'ACTIVEMQ_STATIC_QUEUES=queue1;queue2;queue3' -e 'ACTIVEMQ_MIN_MEMORY=1024' -e 'ACTIVEMQ_MAX_MEMORY=4096' -e 'ACTIVEMQ_ENABLED_SCHEDULER=true' -v /home/ctranoris/testcompose/data/activemq:/data/activemq -v /var/log/activemq:/var/log/activemq -p 8161:8161 -p 61616:61616 -p 61613:61613 webcenter/activemq:5.14.3`

### MySQL server

We use mysql as a storage DB. Please make sure that you have it installed in your system. There are instructions on internet how to install it. Check also our docker-compose installation script

## Oauth server

Keycloak is used as the authentication server.

> Note: Please check the Post installation steps -> Keycloak at localhost, at Deployment/Installation, if you are developing in a local environment

## VNF/NSD Catalog Management and NSD Deployment API service

Clone the repository: https://github.com/openslice/org.etsi.osl.portal.api

Check the application.yml file. Default port is 13080. Especially the datasource username/password, server port.

make sure that the General subsystems are up and running as well as the OAuth server

run it with `mvn spring-boot:run`

You can check your consul server if it registered.

### Swagger API

Swagger API of the service is at `http://localhost:13000/osapi/swagger-ui/`. You can try there various REST actions and authenticate via the OAuth server

## VNF/NSD Catalog Management and NSD Deployment WEB UI service

The Web UI is written in AngularJS

Clone the repository: https://github.com/openslice/org.etsi.osl.portal.web

by default the project org.etsi.osl.portal.api exposes the folder ../org.etsi.osl.portal.web/src/ in a folder testweb (Check class MvcConfig.java in org.etsi.osl.portal.api) for development. (In production nginx is used). Point your browser to `http://localhost:13000/osapi/testweb/index.html/`

## Version/release management
