<p>OpenSlice backend services are mainly implemented with Java 17 or above and Spring boot.</p>
<p>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 docker-compose.yaml file).</p>
<p>To get the latest development branch:</p>
<pre><code class="language-bash">wget https://labs.etsi.org/rep/osl/code/org.etsi.osl.main/-/raw/develop/compose/deploy.sh
sudo ./deploy.sh develop #[or replace develop with other branch name]
</code></pre>
<p>You may follow the <a href="https://osl.etsi.org/documentation/develop/deployment/">installation process</a>, as described at "develop" tagged documentation.</p>
<p>To work on a specific subsystem e.g. org.etsi.osl.tmf.api, you must:</p>
<p>1a - Deploy only the core necessary subsystems through:</p>
<pre><code class="language-bash">sudo docker compose --profile dev down;sudo docker compose --profile dev up -d --build
</code></pre>
<blockquote>
<p>Note <strong>--profile dev</strong> that will only deploy the core dependency subsystems, instead of the whole OpenSlice.</p>
</blockquote>
<p>1b - Or alternatively, commend out the respective container from the docker-compose.yaml file, so as to deploy the whole OpenSlice, except the subsystem you want to work on, following the provided installation steps.</p>
<p>2 - Clone the respective repository, e.g. https://labs.etsi.org/rep/osl/code/org.etsi.osl.tmf.api/-/tree/develop</p>
<p>3 - Code :)</p>

<li>Run the core subsystems (see above section)</li>
