Can't connect to localhost

[felipeZ]

Starting a job like,

import cerise_client.service as cc
import os

# Create a new service for user myuser, with given cluster credentials
env = os.environ
srv = cc.require_managed_service(
        'cerise-mdstudio-gt-myuser', 29593,
        'cerise-mdstudio-gt:test',
        os.environ['CERISE_GT_USERNAME'],
        os.environ['CERISE_GT_PASSWORD'])
cc.start_managed_service(srv)

results in the following error

Hmm, interesting. That suggests that the WebDAV is not running, or that there's some connection/network issue. The GT specialisation is a bit stale at the moment, so perhaps it just needs to be updated to work with the latest Cerise base image. Let's have a look on Wednesday.

[LourensVeen]

The configuration file is definitely stale, which doesn't explain why it can't connect to the WebDAV though.

[LourensVeen]

Ah, the configuration had been updated, but there's a typo resulting in invalid YAML. Cerise should print an error on stdout in that case, so you can get to it via docker log. Or it can use the normal log file at least if the problem is in the API config, because it can still get the logging configuration from the main config.

[LourensVeen]

Log output has been added to Cerise, it ends up in /var/log/cerise/cerise_backend.err in the standard Docker configuration.
