roles/nginx: Allow custom resolvers for TLS stapling
Allows to specify custom DNS resolvers for TLS stapling, with a default
of Cloudflare's public DNS servers.

roles/nginx: Default to Cloudflare public DNS for TLS stapling
No need to give Google even more data or free advertising by using
this as the default! In practice I always use the DNS servers from
the VPS provider anyways.

roles/php-fpm: Use set_fact to set packages
Instead of looping over a list of items to install, we can actually
just give a list directly to the apt module. This allows the module
to install all packages in one transaction, which is faster as well
as slightly safer for some dependency resolution scenarios.

roles/php-fpm: Remove "packages" tag
This tag is no longer reachable after switching to the new dynamic
includes in Ansible 2.4 and 2.5. Anyways, I've been questioning my
decision to add the "packages" tag to any task that uses the apt
module.

roles/php-fpm: Use blocks to tag children of dynamic tasks
When using dynamic includes, child tasks do not inherit tags from their
parents. You must tag the parent and each child task separately, or use
a block to group children and then apply a tag to a block.

roles/nginx: Move WordPress tasks to separate file
Because of the shift from static imports to dynamic includes these
tags will never be reached unless they have their own task that is
tagged at the top-level (dynamic includes don't pass their tags to
their children).

roles: Remove unreachable "packages" tags
After reörganizing for dynamic includes these tags will never be reached
because the children of dynamic includes do not inherit tags from their
parents as they did with static imports.

roles/nginx: Use dynamic includes for Let's Encrypt
As of Ansible 2.4 and 2.5 the behavior for importing tasks has changed
to introduce the notion of static imports and dynamic includes. If the
tasks doing the import is using variable interpolation or conditionals
then the task should be dynamic. This results in quicker playbook runs
due to less importing of unneccessary tasks.

One side effect of this is that child tasks of dynamic includes do not
inherit their parents' tags so you must tag them explicitly or a block.

Also, I had to move the letsencrypt tasks to the main task file so the
tags were available (due to dynamic tasks not inheriting tags).

roles/nginx: Use dynamic include_tasks for Let's Encrypt
Use dynamic includes instead of static imports when you are running
tasks conditionally or using variable interpolation. The down side
is that you need to then tag the parent task as well as all child
tasks, as tags only apply to children of statically imported tasks.

roles/nginx: Separate Debian 9 "stretch" Let's Encrypt deps
Instead of iterating over fifteen packages with a loop that does fifteen
separate apt transactions, it is better to give the apt module a list so
it can install them all in one transaction. This is both quicker and te-
chnically more safe for dependency resolution.

roles/common: Use dynamic include_tasks for packages
Basically, when using conditionals or variables in your tasks you should
use include_tasks instead of import_tasks. The down side is that you now
need to tag all included tasks individually or with a block, unlike when
using static imports (tags are applied to all imported child tasks).

I would actually like to reduce this task to a single one that uses the
host's ansible_distribution variable, but Ansible 2.5.1 currently gives
the following error: ansible_distribution is undefined.

roles/common: Always use security.ubuntu.com
Vanilla Ubuntu (and Debian actually) defaults to using the official
mirror for security updates rather than country or regional mirrors.

Also, for what it's worth, Ubuntu mirrors didn't always sync these
security archives. I'd prefer to stay closer to vanilla Ubuntu but
also it kinda makes sense to get security updates from the official
source than a mirror (in case of delay or errors).

Import OS-specific vars from task in common role
We stopped being able to do dynamic includes from the playbooks around
Ansible 2.4.0.0 if I recall correctly. Instead we can create a task to
include the variables and make it always run by using the special tag.

For now the Debian and Ubuntu vars files are the same, but I will keep
them separate so that it is more flexible in the future.

9f3ab01d48 roles/php-fpm: Use include instead of import for tasks
These tasks are conditional and mutually exclusive due to the "when"
clause. Using import_tasks means that these are imported before the
playbook execution and then skipped during evaluation of the test.

It makes sense in this case to use include_tasks so that the tasks
are only imported during playbook execution if the condition is met.

There are currently no nginx.org builds for Debian 9, so we need to

roles/nginx: Make sure to set HSTS headers on WordPress static files
I realized the other day that due to complex logic in the location

didn't get the HTTP Strict Transport Security header set. We need

nginx overwrites headers if you set them again in a child block.

roles/nginx: Decrease gzip_min_length from 860 to 256
There was some knowledge floating around that 860 bytes was the
optimal size, I think it was from an Akamai engineer or something,
but the HTML 5 Boilerplate server configs use 256 bytes, and I
actually have HTML content that is less than 860 bytes, so I guess
I could benefit from compressing it. gzip compression is costly
for the compression side, but very quick for the client, so this
is a good thing.

Set use_letsencrypt to true for nginx role
The variable name is misleading as this really does is install the

always happen. If a host doesn't want it, they can override it in
their host vars.

Perhaps I should rename this variable to "bootstrap_letsencrypt" or
something so it is more accurate.

Turns out this actually breaks initial deployments, because the
cache gets updated in the first task, then you add sources for
nginx and mariadb, but it doesn't update the indexes because the
cache is < 3600 seconds old, so you end up getting the distro's
versions of nginx and mariadb.

I have added cache_valid_time=3600 for the first task in each

the "nginx" tag is also in the "packages" tag, but sometimes you
run the nginx tag by itself (perhaps repeatadely), so you'd want

of running it's only using 64 or so, so it's really just a waste of
memory.

Also, disable opcache for CLI. What the hell do you need opcaching
in the CLI invocation for? It only persists for one process!

roles/nginx: Use Linode DNS servers for OCSP resolvers
I didn't realize Linode had DNS resolvers, but they are much closer
than anything else (obviously).

Here is OpenDNS:

    # mtr --report 208.67.222.222

    HOST: mjanja                    Loss%   Snt   Last   Avg  Best  Wrst StDev

And here is Linode's:

04e453df51 Revert "roles/nginx: Correct HSTS header in https template"
This reverts commit 5c7404d228.

'always' is legal in nginx >= 1.7.5:

If the always parameter is specified (1.7.5), the header field will be added regardless of the response code.

roles/nginx: Add $request_method to nginx fastcgi_cache_key
nginx is caching HEAD requests, then when users come along and do
a GET request they get an HTTP 200 with no request body. It seems
setting fastcgi_request_methods to GET doesn't stop nginx from caching
HEADs, so for now just add the $request_method to the key.

Remove provisioning user management
It's just too tricky to manage this. Ubuntu / RedHat preseeds and
kickstarts can create the user and add it to groups, but only when
we control the initial boot environment (ie not on Linode, Digital
Ocean, etc), so let's just say we assume this user exists and can
get root with sudo by the some we are running ansible on it.
