I am trying to set up a powerline modded font for SSH connection using apache guacamole docker container.

The container is set up and working and without setting a font name everything works well.

Once I enter a font name I get weird spacing and use of the wrong font, example

Here is how my container is set:

docker run --name=guacamole -d \
--network exposed-containers \
--restart=unless-stopped \
-e GUACD_HOSTNAME=guacd \
-e MYSQL_HOSTNAME=mariadb \
-e MYSQL_DATABASE=guacamole \
-e MYSQL_USER=guacamole \
-e MYSQL_PASSWORD=redacted \
-v /usr/share/fonts/Hack-Regular.ttf:/usr/share/fonts/Hack-Regular.ttf \
-v /usr/share/fonts/dejavu.ttf:/usr/share/fonts/dejavu.ttf \
-v /usr/share/fonts/notomono.ttf:/usr/share/fonts/notomono.ttf \
-p 9011:8080 guacamole/guacamole

Inside the container the fonts are detected and are working fine:

root@49d47e4258d3:/opt/guacamole# fc-list
/usr/share/fonts/truetype/dejavu/DejaVuSerif-Bold.ttf: DejaVu Serif:style=Bold
/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf: DejaVu Sans Mono:style=Book
/usr/share/fonts/truetype/dejavu/DejaVuSans.ttf: DejaVu Sans:style=Book
/usr/share/fonts/dejavu.ttf: DejaVu Sans Mono for Powerline:style=Book
/usr/share/fonts/Hack-Regular.ttf: Hack:style=Regular
/usr/share/fonts/truetype/dejavu/DejaVuSans-Bold.ttf: DejaVu Sans:style=Bold
/usr/share/fonts/truetype/dejavu/DejaVuSansMono-Bold.ttf: DejaVu Sans Mono:style=Bold
/usr/share/fonts/notomono.ttf: Noto Mono for Powerline:style=Regular
/usr/share/fonts/truetype/dejavu/DejaVuSerif.ttf: DejaVu Serif:style=Book
root@49d47e4258d3:/opt/guacamole#

The font I am trying to use is monospace as is needed for guacamole and I have used that font before on linux and windows so I know it works.

What am I missing?

Download a monospace font like Droid Sans Mono

for Centos:

yum install google-droid-sans-mono-fonts

it will download a font named "DroidSansMono.ttf"

now edit user-mapping.xml under /etc/guacamole

My connection parameters are like this

 <connection name="localhost">
            <protocol>ssh</protocol>
            <param name="hostname">ServerName</param>
            <param name="port">22</param>
            <param name="password">PassWord</param>
            <param name="font-name">DroidSansMono</param>
            <param name="font-size">10</param>
   </connection>

Note the font name and the "font-name" parameter are same except ttf extension. I can see the fonts properly now.enter image description here

did you try setting up font config for that font?

Adding the fonts in the guacd container fixes the issue.

The ssh connection is processed by the guacd container. So, instead of adding fonts in guacamole, you need to add them into guacd.
