Welcome screen management

[SitoRBJ]

Hello team,

This PR solves issue #131

First of all we have declared an ARG variable to build the image of Kibana adjusting it to the needs that are required.

• Kibana Dockerfile

ARG CHANGE_WELCOME="false"

Setting this variable to true will imply the desired changes in the welcome screen.

After that, we add the script that makes the changes.

• Kibana change welcome screen script

#!/bin/bash


if [[ $CHANGE_WELCOME == "true" ]]
then

    rm -rf ./optimize/bundles

    kibana_path="/usr/share/kibana"
    # Set Wazuh app as the default landing page
    echo "Set Wazuh app as the default landing page"
    echo "server.defaultRoute: /app/wazuh" >> /usr/share/kibana/config/kibana.yml

    # Redirect Kibana welcome screen to Discover
    echo "Redirect Kibana welcome screen to Discover"
    sed -i "s:'/app/kibana#/home':'/app/wazuh':g" $kibana_path/src/ui/public/chrome/directives/global_nav/global_nav.html
    sed -i "s:'/app/kibana#/home':'/app/wazuh':g" $kibana_path/src/ui/public/chrome/directives/header_global_nav/header_global_nav.js

    # Redirect Kibana welcome screen to Discover
    echo "Hide undesired links"
    sed -i 's#visible: true#visible: false#g' $kibana_path/node_modules/x-pack/plugins/rollup/public/crud_app/index.js
    sed -i 's#visible: true#visible: false#g' $kibana_path/node_modules/x-pack/plugins/license_management/public/management_section.js
fi

• Kibana Dockerfile

COPY --chown=kibana:kibana ./config/welcome_wazuh.sh ./

RUN chmod +x ./welcome_wazuh.sh

RUN ./welcome_wazuh.sh

RUN /usr/local/bin/kibana-docker --optimize

In order to make these changes, it is necessary to eliminate the bundles and optimize them later, which is why these operations are carried out in the indicated order.

We will delete the bundles only if we use the script.

• With these changes when opening in the browser the Kibana portal will automatically take us to the Wazuh APP section.

• Clicking on Kibana's icon will automatically take us to Wazuh's APP.

• Additionally, in the management section, we have deleted two confusing entries for users.

Best regards,

Alfonso Ruiz-Bravo
