Resolution: Invalid
> Debugging failing guacamole client container in AWS ECS
> -------------------------------------------------------
>
> Key: GUACAMOLE-1271
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1271
> Project: Guacamole
> Issue Type: Bug
> Components: guacamole-client
> Affects Versions: 1.3.0
> Environment: Amazon ECS (Amazon Linux 2)
> Reporter: Dominik Borkowski
> Priority: Minor
>
> Hello,
> We use both the client and server guacamole images in Amazon ECS. With recent
> attempt to switch to version 1.3.0 the client containers seem to die upon
> start with the following error:
> {code:none}

> Additional information:
> * Affected image is `guacamole/guacamole:1.3.0`, while
> `guacamole/guacamole:1.2.0` works just fine, as do all the earlier versions
> * Switching back and forth reliably shows that 1.3.0 fails, while 1.2.0
> works fine
> * `guacamole/guacd:1.3.0` works fine
> * Local execution of `guacamole/guacamole:1.3.0` works fine
> * Building from source code at branch 1.3.0 and using that with ECS shows
> the same exact error
>
> I'm a bit at a loss as to how to debug this further. Guacd has an option for
> additional debugging that can be enabled via an environment variable, but I
> can't seem to find one for the client.
> I'd appreciate any input, thank you in advance!
