Massimo Fierro commented on GUACAMOLE-1549:
-------------------------------------------
Oh, I am really sorry for taking up your time. I must have been mistakenly
browsing the devel branch while trying to understand what was going on, so I
didn't even think of looking for another related submission.
> EXTENSION_PRIORITY env var is not respected by Docker container
> ---------------------------------------------------------------

> Key: GUACAMOLE-1549
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1549
> Project: Guacamole
> Issue Type: Bug
> Components: guacamole-client
> Affects Versions: 1.4.0
> Environment: OS: Ubuntu 20.04.4 LTS x86_64
> Docker images: v1.4
> Reporter: Massimo Fierro
> Priority: Major
>
> Running guacamole-client and guacd with docker-compose, it seems like my
> preferred order of extension loading is not respected.
> My docker-compose configuration file looks like the following:
> {code:yaml}
> version: '2.0'
> networks:
> guacnetwork_compose:
> driver: bridge
> services:
> guacd:
> container_name: guacd_compose
> image: guacamole/guacd
> networks:
> guacnetwork_compose:
> restart: always
> volumes:
> - /home/dockeruser/guacamole-data/drive:/drive:rw
> - /home/dockeruser/guacamole-data/record:/record:rw
> environment:
> GUACD_LOG_LEVEL: debug
> guacamole:
> container_name: guacamole_compose
> depends_on:
> - guacd
> environment:
> GUACD_HOSTNAME: guacd

> As you can see the "EXTENSION_PRIORITY" env var is set, and according to
> start.sh it should be processed to set the appropriate property:
> {code:bash}
> // ...
> # Set extension priority if specified
> set_optional_property "extension-priority" "$EXTENSION_PRIORITY"
> # Use api-session-timeout if specified.
> if [ -n "$API_SESSION_TIMEOUT" ]; then
> associate_apisessiontimeout
> fi
> # Set logback level if specified
> if [ -n "$LOGBACK_LEVEL" ]; then
> unzip -o -j /opt/guacamole/guacamole.war WEB-INF/classes/logback.xml -d
> $GUACAMOLE_HOME
> sed -i "s/level=\"info\"/level=\"$LOGBACK_LEVEL\"/"
> $GUACAMOLE_HOME/logback.xml
> fi
> #
> # Finally start Guacamole (under Tomcat)
> #
> start_guacamole{code}
>
> Nonetheless, the docker logs clearly indicate that the extensions are still
> loaded according to filename, ignoring the specified priority:
> {noformat}
> 01:56:13.581 [localhost-startStop-1] INFO o.a.g.extension.ExtensionModule -
> Multiple extensions are installed and will be loaded in order of decreasing
> priority:
> 01:56:13.581 [localhost-startStop-1] INFO o.a.g.extension.ExtensionModule - -
> [openid] "OpenID Authentication Extension"
> (/home/guacamole/.guacamole/extensions/1-guacamole-auth-sso-openid-1.4.0.jar)
> 01:56:13.581 [localhost-startStop-1] INFO o.a.g.extension.ExtensionModule - -
> [mysql] "MySQL Authentication"
> (/home/guacamole/.guacamole/extensions/guacamole-auth-jdbc-mysql-1.4.0.jar)
> 01:56:13.581 [localhost-startStop-1] INFO o.a.g.extension.ExtensionModule -
> To change this order, set the "extension-priority" property or rename the
> extension files. The default priority of extensions is dictated by the sort
> order of their filenames.{noformat}
>
> I tried to understand what the issue might be, to be able to submit a patch,
> but I am kind of stuck because I don't have a good grasp on the bootstrap
> process. I think solving the issue should be relatively simple for anyone
> with a better understanding of the codebase.
> Thanks.
