az containerapp CLI misinterprets container arguments with leading dashes (--args "--config=..." fails)

[jewelmas]

Describe the bug

When attempting to pass runtime arguments to a container using the az containerapp CLI, arguments that begin with double dashes (e.g., --config=...) are incorrectly parsed as CLI flags rather than container arguments.

Related command

az containerapp update
--name my-containerapp
--resource-group my-resourcegroup
--args "--config=/etc/otel/config.yaml"

Errors

Issue script & Debug output

Expected behavior

The container should receive --config=/etc/otel-contrib/config.yaml as a runtime argument.

Environment Summary

Additional context

Please note when run via terraform the above works, only via cli it fails

Hi @jewelmas

Can you try with workaround, use = : --args='--config=/etc/otel/config.yaml'
and check if it work for your case?

az containerapp create -n {} -g {} --args='--config=/etc/otel/config.yaml' --environment {} --image {}

This is a known issue that it will recognize value like --somevalue as a command argument and throw error:

cli.azure.cli.core.azclierror: unrecognized arguments: --config=/etc/otel/config.yaml

Thanks
