UnicodeDecodeError: 'utf-8' codec can't decode byte 0xba in position 109

[Z02X]

What happened?

When I try to add k3s>extraArgs># with arg: --bind-address I get:

[DEBUG] Traceback (most recent call last):

I thought it was something in my file but that doesn't look to be so.

What did you expect to happen?

It passes the command without error.

How can we reproduce it (as minimally and precisely as possible)?

What is the content of the Deckfile you are using?

Anything else we need to know?

I am still trying to see if it's something wrong with my input. My goal is to set the IP to be different then the host IP but on the same subnet. I think it's quite possible that the error is just not being caught and crashing here, something like the IP I set is wrong but that output is getting lost.

I wonder how you managed to bypass the Deckfile validation for the cluster.name attribute. It is missing in your Deckfile.
When running your Deckfile with a recent version of deck I see the following error:

> deck get deck.yaml 
[INFO] Reading Deckfile: deck.yaml
[CRITICAL] There was an error running deck: 1 validation error for Deckfile_1_0
cluster -> name
  field required (type=value_error.missing)

@buschNT any idea?

@buschNT any idea?

@Schille No, currently not. It should always throw the validation error from above when the cluster name is missing.

---

The UnicodeDecodeError is raised by the following part in the code:

            if print_output:
                for stdout_line in iter(process.stdout.readline, ""):
                    print(stdout_line, end="", flush=True)

This is "only" some output printing which is coupled to the logging.DEBUG level (print_output=True if logger.level == logging.DEBUG else False,). @Z02X I guess you used the "-d" flag when running the get command. Maybe it works without the debug output? Nevertheless, even without knowing the exact cause of the UnicodeDecodeError, this part of the code should not raise an error.

@Schille #112 this is a small fix which should prevent getdeck from crashing at this point.

Sorry I think I cut down the deck file a little to much. I will run a test on a less striped down one.

The fix #112 got me to a state where I can see what's going on now instead of crashing so I consider this fixed. Thank you!
