Custom .jar file

[trueself-belief]

Hi

Great work on this. Your comment stating that although this repo is 3 years old the script uses latest images was useful in helping me find and use this.

The custom branding.jar file you are able to add within the guacamole/guacamole:latest container /extensions folder seems to delete after restarting the container. There is one .jar file in there currently (guacamole-auth-jdbc-postgresql-1.3.0.jar)
Any ideas on why this is and any potential fixes to allow a custom login page.

if you want to add a Custom .jar best would be to do it as volume, then you can put whatever you want in there and is stays.

Thank you so much for the direction, I now have something new to learn!
I wanted to keep this open so I could post the solution for others that use this docker file however my understanding is not there yet.
I am wondering if you could assist a little further please...

• I have created a new docker volume using 'docker volume create (volume name)'
• Tried to mount the volume to the container using 'docker run -v (volume name):/root/.guacamole/extensions ubuntu'

however this does not seem to have worked...am i missing something obvious to you here or do i need to spin up a fresh install and add -volume variable to the .yml file?

[Vad1mo]

This is the correct approach.

Now that you have a volume mounted to ubuntu /root/.guacamole/extensions you can add your JAR to that volume, so that next time when you start a new container that mounts this volume, you'll see that the jar is there.

From there you have to tell guacamole to load that jar somehow, but this is purely guacamole related setup.

however this does not seem to have worked...am i missing something obvious to you here or do i need to spin up a fresh install and add -volume variable to the .yml file?

What you now did on the CLI you need to extend to the compose file. Normally are compose up will do it.

[trueself-belief]

Ok.

My problem here is that this creates a new container but I want to put the .jar within a container created by your script, so instead of using ubuntu image can i specify the container image name to mount the volume into your container? ie
guacamole/guacamole:latest@sha256:0xxxxxxx

Try this:

...
    volumes:
      - extensions:/root/.guacamole/extensions

I've tested this but appear to be getting a 502 bad gateway error (nginx), odd as the script works without the extension added. I wanted to allow enough time to allow it to fully propagate (24hrs) just in case, cache has been cleared and a simple refresh, firewall disabled and I also set up a new subdomain to run it through but none have worked. I will take this away and do some more testing but does the same happen your side?

At this point i just want to say thank you so much for the guidance you have shared with me, you have helped me step into the next section of learning with the clarification and support you have offered and such quick responses.

I got the same error when using root/.guacamole/extensions as the directory.

However, I found a solution:

volumes:
      - extensions:/opt/guacamole-dockerized/extensions

environment:
      GUACD_HOSTNAME: guacd
      POSTGRES_HOSTNAME: postgres
      POSTGRES_DATABASE: ${POSTGRES_USER:-guacadb}
      POSTGRES_USER: ${POSTGRES_USER:-guacadb}
      POSTGRES_PASSWORD:
      LETSENCRYPT_TEST: ${LETSENCRYPT_TEST:-false}
      VIRTUAL_HOST:
      LETSENCRYPT_HOST: ${VIRTUAL_HOST}

Thank you for sharing. I'll reference this on the README

[carlostico]

the branding.jar file dissapears from the volume created as soon as the container is restarted
