KB - Configbuilder errors during startup

• Microgateway

The following errors result in an error log message and prevent the container from starting up.

• General errors
• an external file is explicitly referenced but not found

• Errors in config.yaml
• the config.yaml file is not a valid YAML file or does not exist
• invalid attributes are used
• invalid values are used
• structure mismatch, e.g., providing a single value when a list is expected

0. Instruction
1. Check the path of the corresponding DSL attribute with the suffix _file.
2. Check if the file is available in the configbuilder container.
3. Either correct the path in config.yaml or mount the file accordingly.
4. The configbuilder can access the files configured with the DSL attributes _file.

0. Instruction
1. Check if the configuration file is available in the configbuilder container at /config/config.yaml.
2. Check that the DSL attributes are used correctly.
• Correct attribute name
• Correct attribute value
• Correct attribute type


Use the (Microgateway) DSL reference to accomplish this task. The referenced examples might help as well.

3. Check with a YAML syntax checker, whether it is valid YAML.
4. The Configbuilder can successfully read and interpret the config.yaml file.
