Using VNCserver + GUI application + Virtual Display in Docker container
I managed to found the solution:
Changed the script in Attempt 3 above as follows worked
!/bin/bashXvfb :1 -screen 0 800x600x16 &/usr/bin/x11vnc -display :1.0 -usepw &DISPLAY=:1.0export DISPLAYfirefoxCheers.
I'm using the following Bash function:
# Configure virtual display and wine.# Usage: set_displayset_display() { export DISPLAY=${DISPLAY:-:0} # Select screen 0 by default. xdpyinfo &>/dev/null && return if command -v x11vnc &>/dev/null; then ! pgrep -a x11vnc && x11vnc -bg -forever -nopw -quiet -display WAIT$DISPLAY & fi ! pgrep -a Xvfb && Xvfb $DISPLAY -screen 0 1024x768x16 & sleep 1 if command -v fluxbox &>/dev/null; then ! pgrep -a fluxbox && fluxbox 2>/dev/null & fi echo "IP: $(hostname -I) ($(hostname))"}Then source the file and call set_display. Consider configuring the password via -usepw.
I'm using it in the following Docker project (check .funcs.cmds.inc.sh).
