Marc and Dre,

I have Ubuntu 16.04 and 18.04 servers up and running and both have python2.7+ and python 3.3 or greater.   Some of that worry may be mitigated for python.

I appreciate you getting back with me.

Marc and Dre,

I will review the several PRs you noted this week.  I used RedHat linux when I worked semiconductor design.   I can easily build a centOS 6.9 or 7.5 server on the cloud service I use (Digital Ocean).  Linux is odd with the number of distribution but for most part they interchangeable once they are setup.

Project requirements
=====================
- calendars
Tournaments
Leagues
Company based
Single shared calendar for organization/event

- Users
Projects will not have individual users (calendar for one organization)
mostly controlled on the backend of a web interface
- Ability to filter shared calendars based on keywords (Leagues for Schools)
Swimming vs Basketball
Baseball vs Track and Field
Simpler answer: have distinct calendar for each sport
- Currently the leagues for my high school and middle school kids do not even offer a calendar 
They switched to an app
I see this as backwards, prefer to see everything in one place

Questions
==========
- What is the expected timeframe to complete the move to python3.x?
Implementation of  a calendar services can wait for now.
- Is there any plans to look at swift instead of python?
I am implementing my php classes in swift for web development.   I think when I get past the learning curve it will be much better than php.

And luckily you can use redhat7 or centos7, that has python 2.7 and will
backport anything serious until their eol

Hi,

Probably the closest thing to setup documentation that exists for
CalendarServer are the Docker integrations contributed in PRs 513
<https://github.com/apple/ccs-calendarserver/pull/513>  and 489
<https://github.com/apple/ccs-calendarserver/pull/489>  (neither are merged so far; see following paragraph):

https://github.com/apple/ccs-calendarserver/pull/513/files

Depending on the scope and nature of your new projects, I would advise
somewhere between "some caution" and "an abundance of caution" as you
consider whether to use CalendarServer. On the plus side, the test
coverage is good (both unit tests and integration tests) and the
existing features are pretty stable. On the not-as-plus side, have a
look at the code frequency graph
<https://github.com/apple/ccs-calendarserver/graphs/code-frequency>  while ruminating on the fact that this project uses Python 2.7, the support lifetime <https://pythonclock.org>  
for which ends in just over one year. The bulk of the dependent modules
(i.e. Twisted) are safe on 3 at this point, however an unknown amount of
work remains to get CalendarServer safe for 3. Someone gave this a quick
shot which is detailed in this PR:
https://github.com/apple/ccs-calendarserver/pull/501 - I don't know if
this produces a functional service, but I do know that the tests don't
pass.

A slightly expanded version of this information:
https://github.com/apple/ccs-calendarserver/issues/488

Developers,

I am interested in creating a calendar and contact server to use in
several new projects.  It would allow me make a better options then
existing sites.  The problem I face is a good set of documentation on
how to get it setup and running.  Development platform for my projects
will be Ubuntu linux of at least 14.04LTS or 16.04LTS.  I am willing to
document precisely how to do it if I can find a better starting point.  
The current documentation is basic and seemingly missing some
information.

Any help would be appreciated.
