I do like having the tools. I think they make cloudstack installs more
robust and repeatable. The setup instructions are already pretty involved,
adding another 15-20 steps/commands is going to create that many more
support questions. It seems easy for those of us already familiar, but if a
newbie misses or doesn't understand one thing they're totally lost.


The current shape the scripts are in is horrible, they have all kinds of 
dead code in them and a bunch of Python dependencies. It could easily be 
rewritten in BASH to make it all easier.

I do like the idea of documenting what each script should do, so ad mins
can adjust their config management if they wish. If we remove the scripts,
we have to maintain the documentation anyway, which is really just the
scripts spelled out on an HTML page.

True, but that should be the goal. These scripts should not be 
mandatory, since a lot of admins will use Puppet or Chef to provision 
their systems (mainly hypervisors).

------------------------------------------------

The current state of these tools is horrible. So if we intend to keep
them, they have to be rewritten anyways.

cloud-setup-* should be removed

                 Key: CLOUDSTACK-1147
                 URL:
https://issues.apache.org/jira/browse/CLOUDSTACK-1147
             Project: CloudStack
          Issue Type: Improvement
      Security Level: Public(Anyone can view this level - this is the
default.)
          Components: Install and Setup
    Affects Versions: 4.0.0
            Reporter: Wido den Hollander
             Fix For: 4.2.0


The tools like cloud-setup-databases, cloud-setup-management and
cloud-setup-agent seem to come from the vmops/cloud.com time where
CloudStack used to be a black box appliance.
Now more and more people start using CloudStack I'm seeing all kinds of
criticism on these tools:
- They change files without telling the admin
- They punch wholes through firewalls
Those are two things which make sysadmins cry, especially if they want
to manage their systems with Puppet or Chef.
The steps for setting up an Agent are actually not that big and most of
them are actually already documented.
When a host is added through the GUI we shouldn't run cloud-setup-agent,
but we should just check if the host is ready to be added and bail out if
not. (And tell why)
The same goes for the management server and databases.
The databases is just a matter of importing the correct SQL files into
the databases and populating db.properties with the correct credentials.
Setting up the management server is also just a matter of creating the
correct configuration files, firewalling ports and setting sudo permissions.
We should tell system administrators what it is that he/she has to
configure, not just do things without telling.
Documentation is key here I think.
