Ravinder,
I don't understand Docker and why I would want to use it.
Is Docker for building and deploying web apps in a "Docker" container or something else?
Yes Neo, it is about how we could make our applications/custom solutions dependency FREE(lets say our codes have certain packages for example Python has Flask, Django etc and we are moving from our current box(just taking a scenario only) to new box on which dependencies are NOT installed then SOLUTION for this is Dockerise your codes/solutions. By which we need NOT to worry if our same code will run on other system or NOT, since it may be different from current working system). My intention to learn it for DEVOPS purposes and share in forums here so that new users could come here for these questions and may be we could learn more. I didn't mean that we in forum's backend systems should use it or so.(Who knows if you feel its powerful we could use it in future, but my intention is only learning, sharing and pulling people on forums by sharing it here).
Thanks,
R. Singh

NAME
Web::Simple::Deployment - various deployment options
DESCRIPTION
This file documents common deployment methods for Web::Simple. If you feel one is missing, please ask in the IRC channel and we'll work
with you to add it.
CGI
The most basic deployment option is as a CGI script loading and running your Web::Simple-module:
#!/usr/bin/env perl
use Your::Web::Simple::App;
Your::Web::Simple::App->run_if_script;
Save that as script.cgi and your web server will handle it correctly.
Plack-Server
This works in with exactly the same code as CGI deployment. However instead of letting your web server load script.cgi, you run this on the
command line:
plackup script.cgi
Self-contained CGI
Sometimes your app is so small that you have only one or two tiny classes that you want to run as a CGI script. Web::Simple offers a
helpful mechanism to achieve that.
#!/usr/bin/env perl
use Web::Simple 'HelloWorld'; # enables strictures and warnings for the file
# additionally, HelloWorld is upgraded to a
# Web::Simple application
{
package HelloWorld;
sub dispatch_request {
sub (GET) {
[
200,
[ 'Content-type', 'text/plain' ],
[ 'Hello world! It is a fine ' . HelloWorld::Helper->day ]
]
},
sub () {
[ 405, [ 'Content-type', 'text/plain' ], [ 'Method not allowed' ] ]
}
}
}
{
package HelloWorld::Helper;
use DateTime;
sub day {
return DateTime->now->day_name;
}
}
HelloWorld->run_if_script;
