Can't disable debug messages when using Packer as a library

[Pedro Pereira]

Hey list!

So, I'm using Packer as a library for a little Go project and I'm having trouble with controlling the output of the builds as I can't disable the debug messages.

What I did so far was:

• Created a Core Config
• Created a Packer Core based on the Core Config by calling packer.NewCore(config)
  
• Created a Build by calling Packer Core's .Build() function
• Called SetDebug(false) on the build generated on the step above
• Called Prepare() and then Run()
• It doesn't matter which type of UI I pass to Run() the debug messages are still shown.
  

The build process works just fine and an image is created in my GCP account. But I keep seeing multiple debug messages even after calling SetDebug() before calling Prepare(), as instructed by the comments in Packer's source code. For example:

2019/08/08 14:50:01 [DEBUG] Opening new ssh session
2019/08/08 14:50:01 [DEBUG] Starting remote scp process:  scp -vt /tmp
2019/08/08 14:50:01 [DEBUG] Started SCP session, beginning transfers...
2019/08/08 14:50:01 [DEBUG] Copying input data into temporary file so we can read the length
2019/08/08 14:50:01 [DEBUG] scp: Uploading script_7943.sh: perms=C0644 size=61
2019/08/08 14:50:01 [DEBUG] SCP session complete, closing stdin pipe.

Does anybody have any pointers? What am I missing here?

Ah. SetDebug is meant to tell the Packer build to run in debug-mode, which means pausing between steps. It doesn't control the debug logging. The debug logging is handled by setting or not setting PACKER_LOG=1, and the behavior is controlled and can be read in `logOutput()` in log.go.

Megan,

This helped immensely, thank you!

I was trying to understand why that function wasn't working. All I had to do was configure "log" the way I needed.

Cheers,

Pedro Pereira
