Questions: when does openbox rc.xml.template got initialized and how to add a polybar entry

[eastpyne]

I have a few questions that are not issues, but I am unsure where to ask them. Please let me know if this is not the appropriate place to open such queries. Appreciate your help in advance.

1. I followed your example to add xterm as an app. How can I configure it to open maximized when the Docker container starts? I believe I need to add a statement to /opt/base/etc/openbox/main-window-selection.xml, but I am unsure which one. Could you please advise?

2. I successfully added both polybar and xterm to the Docker container. How can I ensure both apps load at startup, so I have a taskbar and xterm running simultaneously? On a normal system, I would add exec polybar to /etc/xinitrc or ~/.xinitrc. What is the equivalent for the Docker setup?

Update to question 2:

I successfully added a service such as Polybar (learned and modified from the included openbox service). Here's how you can do it:

1. Add Polybar to the Dockerfile:

   RUN add-pkg polybar  # This is equivalent to apk add --no-cache polybar

2. Create Initialization Script:
   In rootfs/etc/cont-init.d/, add a file named 10-polybar.sh. This script will be executed by /init.sh, which is part of the jlesage/baseimage-gui.

   #!/bin/sh
   
   set -e  # Exit immediately if a command exits with a non-zero status.
   set -u  # Treat unset variables as an error.
   
   mkdir -p /var/run/polybar
   chown $USER_ID:$GROUP_ID /var/run/polybar

3. Configure the Service:
   In rootfs/etc/service.d, create the following structure:

   rootfs/etc/service.d
   ├── gui
   │   └── polybar.dep
   ├── polybar
   │   ├── disabled
   │   ├── run
   │   └── xvnc.dep
   

   • The gui/polybar.dep file is necessary for Polybar to start.

   • In the run file:

     exec /usr/bin/polybar

   • In the disabled file:

     if is-bool-val-true "${BAR:-0}"; then
         echo "false"
     else
         echo "true"
     fi

By following these steps, you can add and configure Polybar as a service in your Docker environment.
