Initial setup for mediawiki

This has php-fpm from alpine, with needed modules.
This has nginx from alpine, with more_headers.
This uses redis and postgres - alpine images.

+The pg_data -- needs to be whatever it wants to be (in order to initialize correctly).
+
+Once it is setup, you can chown -R 1000:100 pg_data and use the user: "1000:1000" in 
+docker-compose.
+
+
+Ok, and nginx, php, they all just work as 1000:1000.  :D  Even the socket work.

+;   max children reached - number of times, the process limit has been reached,
+;                          when pm tries to start more children (works only for

+;   content length       - the content length of the request (only with POST);
+;   user                 - the user (PHP_AUTH_USER) (or '-' if not set);
+;   script               - the main script called (or '-' if not set);
+;   last request cpu     - the %cpu the last request consumed
+;                          it's always 0 if the process is not in Idle state
+;                          because CPU calculation is done when the request

+;   last request memory  - the max amount of memory the last request consumed
+;                          it's always 0 if the process is not in Idle state
+;                          because memory calculation is done when the request
+;                          processing has terminated;
+; If the process is in Idle state, then informations are related to the
+; last request the process has served. Otherwise informations are related to

+;       It's available in: /usr/local/share/php/fpm/status.html
+;
+; Note: The value must start with a leading slash (/). The value can be

+ 
+; The ping URI to call the monitoring page of FPM. If this value is not set, no

+; The log file for slow requests
+; Default Value: not set
+; Note: slowlog is mandatory if request_slowlog_timeout is set
+;slowlog = log/$pool.log.slow
+ 
+; The timeout for serving a single request after which a PHP backtrace will be
+; dumped to the 'slowlog' file. A value of '0s' means 'off'.
+; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
+; Default Value: 0
+;request_slowlog_timeout = 0
+ 
+; The timeout for serving a single request after which the worker process will
+; be killed. This option should be used when the 'max_execution_time' ini option
+; does not stop script execution for some reason. A value of '0' means 'off'.
+; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
+; Default Value: 0
+;request_terminate_timeout = 0
+ 
+; Set open file descriptor rlimit.
+; Default Value: system defined value
+;rlimit_files = 1024
+ 
+; Set max core size rlimit.
+; Possible Values: 'unlimited' or an integer greater or equal to 0
+; Default Value: system defined value
+;rlimit_core = 0
+ 
+; Chroot to this directory at the start. This value must be defined as an
+; absolute path. When this value is not set, chroot is not used.
+; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
+; of its subdirectories. If the pool prefix is not set, the global prefix
+; will be used instead.
+; Note: chrooting is a great security feature and should be used whenever 
+;       possible. However, all PHP paths will be relative to the chroot
+;       (error_log, sessions.save_path, ...).
+; Default Value: not set
+;chroot = 
+ 
+; Chdir to this directory at the start.
+; Note: relative path can be used.
+; Default Value: current directory or / when chroot
+;chdir = /var/www
+ 
+; Redirect worker stdout and stderr into main error log. If not set, stdout and
+; stderr will be redirected to /dev/null according to FastCGI specs.
+; Note: on highloaded environement, this can cause some delay in the page
+; process time (several ms).
+; Default Value: no
+;catch_workers_output = yes
+
+; Clear environment in FPM workers
+; Prevents arbitrary environment variables from reaching FPM worker processes
+; by clearing the environment in workers before env vars specified in this
+; pool configuration are added.
+; Setting to "no" will make all environment variables available to PHP code
+; via getenv(), $_ENV and $_SERVER.
+; Default Value: yes
+;clear_env = no
+
+; Limits the extensions of the main script FPM will allow to parse. This can
+; prevent configuration mistakes on the web server side. You should only limit
+; FPM to .php extensions to prevent malicious users to use other extensions to
+; exectute php code.
+; Note: set an empty value to allow all extensions.
+; Default Value: .php
+;security.limit_extensions = .php .php3 .php4 .php5
+ 
+; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
+; the current environment.
+; Default Value: clean env
+;env[HOSTNAME] = $HOSTNAME
+;env[PATH] = /usr/local/bin:/usr/bin:/bin
+;env[TMP] = /tmp
+;env[TMPDIR] = /tmp
+;env[TEMP] = /tmp
+
+; Additional php.ini defines, specific to this pool of workers. These settings
+; overwrite the values previously defined in the php.ini. The directives are the
+; same as the PHP SAPI:
+;   php_value/php_flag             - you can set classic ini defines which can
+;                                    be overwritten from PHP call 'ini_set'. 
+;   php_admin_value/php_admin_flag - these directives won't be overwritten by
+;                                     PHP call 'ini_set'
+; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
+
+; Defining 'extension' will load the corresponding shared extension from
+; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
+; overwrite previously defined php.ini values, but will append the new value
+; instead.
+
+; Note: path INI options can be relative and will be expanded with the prefix
+; (pool, global or /usr/local)
+
+; Default Value: nothing is defined by default except the values in php.ini and
+;                specified at startup with the -d argument
+;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f [email protected]
+;php_flag[display_errors] = off
+;php_admin_value[error_log] = /var/log/fpm-php.www.log
+;php_admin_flag[log_errors] = on
+;php_admin_value[memory_limit] = 32M
