I guess you built you images with nix? You should use fakeNss or shadowSetup. There are many programs out there which will fail without it.

dzmitry-lahoda · 2023-08-04T12:02:41Z

yeah, fixed liked that.

but process compose is ideal with nix as nix already decent isolation, just need some decent process manager working slick out of box.

thenonameguy · 2023-08-04T12:05:46Z

Great response @adrian-gierakowski.

This is not a bug in process-compose, it's fair to assume for the common usecases that nss will be set up.

IMO this should be closed.

dzmitry-lahoda · 2023-08-04T12:29:08Z

@thenonameguy for this exact case, user name is used only to setup logging file name.

func GetLogFilePath() string {
	val, found := os.LookupEnv(LogPathEnvVarName)
	if found {
		return val
	}
	return filepath.Join(os.TempDir(), fmt.Sprintf("process-compose-%s%s.log", mustUser(), mode()))
}

not sure if this is really blocker to not use user and make nix use cases simpler.

if there was more complicated use, like some security setting or like, sure, but in this case it is not needed to be like that.

fix also could be set LogPathEnvVarName as I see.

but seems fix is just if no user than %s for user would be empty string because no user

thenonameguy · 2023-08-04T12:48:18Z

I see, fair point.

I guess a fallback to the stringified PID of the process-compose process itself would be preferable.

Since that would not be a breakage and still keep some form of isolation between concurrently running process-compose instances, it would be a fine relaxation of the runtime environment dependencies.

fix is simple, so it would take me hours to catch up with the thing because i am not go dev. will donate 50 usd in crypto to project for fix. btw another nice use case why nix/guix/(partially will work on win/mac sandboxes so) may be target nieche for product #87

F1bonacc1 · 2023-08-26T12:09:41Z

Hi,

Sorry for the late response. I was away for some time.
What would be the expected fallback in this case?

Not to fail the PC (exit=1).
Return an empty string.
Return a predefined ENV variable and fail if nothing is defined.
Return some arbitrary value UNKNOW or NOBODY.
Something else?

dzmitry-lahoda · 2023-08-26T14:22:38Z

most complex fix to use specific mod to detect user on non posix compliant systems. i guess go has one. so it will detect root in this case.

in docker afaik there is USER env set usually, try it may be too. it seems set without shadow. https://unix.stackexchange.com/questions/76354/who-sets-user-and-username-environment-variables/76356

empty string will work great too.

i guess most automated way will work.

dzmitry-lahoda · 2023-08-26T14:25:19Z

what would happen in case of conflict using same file? new PC will fail to start? can add root process id as suffix for any files created as part of run?

F1bonacc1 · 2023-09-08T14:40:47Z

Will be fixed in the next release.
There will be a warning message, that can be avoided if USER env variable is defined.

F1bonacc1 · 2023-09-11T19:21:01Z

what would happen in case of conflict using same file? new PC will fail to start? can add root process id as suffix for any files created as part of run?

Since Process Compose opens a port, without changing the default one, 2 instances of PC won't run. In other cases where you need to run 2 instances in the same environment, I suggest using the PC_LOG_FILE environment variable.

F1bonacc1 · 2023-09-17T19:34:48Z

Fixed in v0.65.1
