Chapter 10: Provisioning of Rails app fails

[c3er]

If I try the example Vagrantfile of the Rails deployment example, it fails at the task "geerlingguy.passenger : Add Phusion apt repo." with the message "apt cache update failed".

Below, an excerpt of the Vagrant/Ansible output. vagrant up failed with the same error before. This excerpt also includes a deprecation warning for the task "geerlingguy.nodejs : Add npm_config_prefix bin directory to global $PATH".

$ vagrant provision

[...]

TASK [geerlingguy.nodejs : Add npm_config_prefix bin directory to global $PATH.] ***
[DEPRECATION WARNING]: evaluating 'nodejs_generate_etc_profile' as a bare 
variable, this behaviour will go away and you might need to add |bool to the 
expression in the future. Also see CONDITIONAL_BARE_VARS configuration toggle. 
This feature will be removed in version 2.12. Deprecation warnings can be 
disabled by setting deprecation_warnings=False in ansible.cfg.

I had the same problem.

See also the issue Keyserver Timeout for the Ansible role geerlingguy.passenger.

I have therefore made the following local changes to the geerlingguy.passenger role:

# Passenger repository setup.
- name: Add Passenger apt key.
  apt_key:
    keyserver: hkp://keyserver.ubuntu.com:80
    id: 561F9B9CAC40B2F7
    state: present

- name: Update ca-certificates package.
  apt: name=ca-certificates state=latest update_cache=yes

- name: Add apt HTTPS capabilities.
  apt: name=apt-transport-https state=present

After modifying the keyserver and adding the task to update the ca-certificates package, it worked again.

I'm going to be working on this example a little bit today, too...

Gah... fix one thing, two others break.

I'm going to have to work on revamping the entire https://github.com/geerlingguy/demo-rails-app setup again, for Ruby 2.7.x (or maybe redo it entirely for the latest versions of Ruby and Rails...), because trying to get the dependency chain working with a demo app that has multiple versions and each version has a Gemfile.lock tied to a specific Ruby/Bundler version... it's definitely a new form of dependency hell :P

For now I'm going to leave the example mostly intact, but still bump the Ruby version I install in the example. I'll have to revisit this example so CI can pass again, but for now I'm going to pause the CI testing for this playbook example :(
