So i cleaned this up so that the plugin install is gone now as it is done on container image build. Also the image includes the Templates and Sample alerts so i adopted the script to deliver the files via the local files that are included in the container.
We Download and install all external dependencys in our container. So no network intreraction will be required by Kibana on launch of the container. This also saves time on launch as the plugin only has to be installed on container build. So with this dockerfile all stuff is in the image and does not need downloads on deploy.
Added WAZUH_KIBANA_PLUGIN_URL variable to wait-for-it.sh so that kibana plugin installation URL can be overwritten (the default still points to https://packages.wazuh.com/wazuhapp/wazuhapp-2.0_5.3.0.zip).
This is useful in (most likely corporate) environments where there is no egress to the internet or users just prefer to mirror all software locally.
Could also be useful to test a different version of the plugin.
