Configurable Cloud VM is a small command line tool for automatically creating development and demo environments for complex projects. The tool sets up these development environments inside a virtual machine which it automatically creates on the user’s host computer. This avoids polluting the user’s host machine with components from the chosen development environment and provides a clean, predictable and repeatable environment in which this development environment can run.

Create 'stack' user for devstack workload #84

Closed ganeshmaharaj closed 6 years ago

ganeshmaharaj commented 6 years ago

Devstack assumes the user starting stack and all the follow-on services is 'stack' and has hardcoded that in a few locations. This change creates a user with that name for devstack workload and stacks under that user.

@ganeshmaharaj I'm unable to connect to the VM using this workload. Not sure why. Perhaps the user account created by the xenial workload is failing. This might happen if the stack account got created first and took the UUID of 1000. Does it work for you?

Yes, I was able to login into the VM and stack the system. I was on a fedora machine. Let me try this out on a Ubuntu host.

@ganeshmaharaj Try it a few times. Sometimes it works for me sometimes it doesn't work. When it fails I can still log into the instance using netcat. I see that there is only one user, stack, and it has the uid the xenial workload assigns to the default account, which is presumably why the user account did not get created. It seems as though cloud-init on ubuntu is processing the user accounts in random order, or perhaps in parallel.

Aaah.. just thinking out loud, any reason we wish to specify the primary user's uid and gid against letting the system choose it? That might overcome this issue.

because 9p file sharing doesn't work if the uid of the user on the host and the guest differ.

markdryan commented 6 years ago

Options are:

  1. Don't inherit from xenial.
  2. Hardcode the uid for the stack user.
  3. Add a template function that will return a UID that is not the UID of the host user.
  4. See if there's a bug in cloud-init about this and whether it's fixed.
