How to resolve permission denied @ rb_sysopen

Question

I am writing a simple recipe to create file like:

file '/myfile' do
  content 'Welcome to Technical Guftgu'
  action :create
end

but on chef-client -zr "recipe[test::recipe1]" i am getting the following error:

[2022-03-08T10:54:16+00:00] ERROR: Running exception handlers
Running handlers complete
[2022-03-08T10:54:16+00:00] ERROR: Exception handlers complete

As the answer(s) point out, its a permissions issue. You are trying to create a file in root (`/`) directory. Does the user with which you are running `chef-client` have permission to create file in this path? — seshadri_c, Mar 09 '22 at 06:05

It seems that your app does not have access to the file /myfile.

Try this, to allow access to all: sudo chmod a+rw /myfile

it seems you are not executing this as a root user, change it to root by typing sudo su then rerun the command, hopefully this will help.

I was facing the same issue and stuck for an hour, just did it and succeeded.

Errno::EACCES Means "Permission Denied"

The Errno class is mapped to your system call errors at runtime. You can find this (confusingly) documented in:

In particular:

Errno.constants.include? :EACCES
#=> true

on most *nix sytems Errno::EACCES maps to the libc error code for "permission denied". Specifically:

Macro: int EACCES

    "Permission denied." The file permissions do not allow the attempted operation.

That generally means your #create action doesn't have permissions to read, write, or traverse the path to the file you are trying to manage, so you need to change your implementation (which you don't show in your original post) to ensure that your Ruby process has the needed file or filesystem permissions to perform the requested operations.
