Because of my lack of experience with Habitat , so I would like to ask if you have any examples of running a simple application using the Habitat CLI for Windows. Like Node.js,Nginx and so on. Please show me. Grateful

Hi @Fishbone

Have you had a look at the learning stream for Windows? https://www.habitat.sh/demo/windows/steps/1/

Let me know if thats what you were looking for, or if you need something else.

Yes.I have tried this. I just followed the steps and copied the codes,but when I was building there were something wrong and I didn’t how to deal with them.(I called ‘hab studio enter -w’ and then ‘build’)

I also have a question.(This question is unrelated to the above)

How to deal with this when it happen:

The red part means "Access denied".

Hi i need some help regarding habitat application deployment, where to define target machine ip address for with out exporting docker manual commands through chef habitat.

plz give some suggestions

It sounds like the build is not finding the app source code. The best thing to do when things go wrong in this tutorial is to clone the finished plan at https://github.com/habitat-sh/contosouniversity and compare that to the directory structure you have been building in the tutorial.

Regarding the “Access denied” errors, I would guess that the current user might not have write access into your hab directory. I’d suggest opening your console as an admin user.

@mwrock I am also facing this access denied error quite frequently when trying to load a service or installing a package. I do have admin access and opened powershell as admin.
Here is the debug trace:

Couple of things I validated:

  • the core/sqlserver and its dependent package dsc both are available in my local cache.
  • the secret key - core-20180119235000 is also available in C:\studio\hab\cache\keys
  • I tried deleting this key and it gets regenerated next time I try to fetch some packaged from builder.
  • I also tried loading the package via hab svc load command which also results in same error.

Thanks,

Hmm. That is strange. This failure would occur after the install process has succesfully downloaded the hart and expanded it to a temporary folder under hab/pkgs/<origin>/<name>/<version>. The error is occuring when renaming that directory to hab/pkgs/<origin>/<name>/<version>/<release>. I would check to see if there is already a release directory present from a interrupted install. If so deleted. This seems unlikely but it is worth looking for.
