I guess "--allow-unauthenticated" will work but at users own risk.

You can sign up for $300 in free credits, which will be more than sufficient to complete all of the labs in this tutorial.

it is inferred you need funds for the Google Cloud Platform. While you can apply for the free credits, it does not guarantee that it'll be approved. I've tried myself, informing them I wish to learn more about the platform as a new coder and was denied.

I feel that what is needed, such as paid services, should be made a little more clear.

In 02-manual-operations.md the instruction:

glcoud compute instance create

will/may fail with a message to enable "enable Compute Engine API". The error message also gives the fix which is to follow the link and enable the API: https://console.developers.google.com/apis/api/compute.googleapis.com/overview?project=xxxxxxxxxxxx then retry

The current script pulls down the latest version and does not take into account that the Gem file calls for a specific version, and will not compile properly. A tweak to the installation of bundler must be done to get the right version:

replace:

gem install --no-rdoc --no-ri bundler

With:

gem install bundler -v "$(grep -A 1 "BUNDLED WITH" ~/raddit/Gemfile.lock | tail -n 1)"

If I try and run ansible-playbook deploy.yml
It fails with this message

 [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match
'all'

 [WARNING]: Could not match supplied host pattern, ignoring: raddit-app

In 04-packer.md, the step "Create custom machine image", I got the error

googlecompute: google: could not find default credentials.
See https://developers.google.com/accounts/docs/application-default-credentials for more information.

After googling, I found this link https://www.packer.io/docs/builders/googlecompute.html and it help me to fix the above error.

Step to fix :

1. "Compute Engine Service Account" need to be created
2. Export the JSON file
3. Then add a option "account_file" into addit-base-image.json

Please let me know if I am missing any step that causes this error.

Thanks

While running through the Manual Operations section I encountered the following error when trying to run bundle install in the raddit project:

An error occurred while installing tilt (2.0.8), and Bundler cannot continue.
Make sure that `gem install tilt -v '2.0.8' --source 'https://rubygems.org/'` succeeds before
bundling.

running the suggested command gave me this:

Fetching: tilt-2.0.8.gem (100%)
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /var/lib/gems/2.3.0 directory.

This is after following all the previous instructions, and indeed it also occurs when running the 'Scripts' version of the instructions so it seems to be systemic

@Artemmkin I am new to IaaC and I am following your tutorial,
Getting this error while installing mongodb :

==> googlecompute: W: GPG error: http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D68FA50FEA312927
==> googlecompute: W: The repository 'http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 Release' is not signed.

Could you please guide me please ?
