the tosca automates the creation of your runtime
more like an installer
 
Hakase
Hakase
I come from windows background, so is it like an .exe or a source code file?
nah I'm still confused
 
Armin
Armin
for example, tosca can create a vm on an openstack instance, installs the os on the vm, installs all needed dependencies, like mongodb and nodejs, gets the program, you want to run, configures everything and starts it
 
Hakase
Hakase
what's openstack?
 
Armin
Armin
a program to manage virtual machines
it can create them, delete them, open ports of them, close them, associate ips or urls with them and so on
 
Hakase
Hakase
oh ok this is clear now
so basically simulating a clean install on a brand new computer?
 
Armin
Armin
4:03 PM
not only simulating
it really does all of this
afterwards you can go to your vm and everything is there...
 
Hakase
Hakase
but it's inside a vm, so it's not as realistic as automated installation on an actual dedicated desktop
aren't there any problems with that approach?
 
Armin
Armin
well, many things aren't run on a physical machine but rather vms
here is some information about tosca: docs.oasis-open.org/tosca/TOSCA/v1.0/TOSCA-v1.0.html
i haven't read it but it is the complete specification

I've been using vmware workstation for my VMs where I can add/remove devices and change quotas on hard drive space and max ram available, is it like that?
 
Armin
Armin
@ton.yeung i don't know whether it is only a container or a real vm... to be honest, i don't really care either...
it works, that's enough for me xD
 
Hakase
Hakase
4:10 PM
ok so how do containers work and how are they different in usage?
and what is the full name of those containers so I could google up the info
just "container" is not gonna work obv
 
HoiHoi-san

@ton.yeung The Wikipedia contains no knowledge of such a thing

Operating-system-level virtualization
Operating-system-level virtualization is a server virtualization method in which the kernel of an operating system allows the existence of multiple isolated user-space instances, instead of just one. Such instances, which are sometimes called containers, software containers, virtualization engines (VEs) or jails (FreeBSD jail or chroot jail), may look and feel like a real server from the point of view of its owners and users. On Unix-like operating systems, this technology can be seen as an advanced implementation of the standard chroot mechanism. In addition to isolation mechanisms, the kernel...
this?
it did work :p
 
Armin
Armin
@Hakase well, a container uses pretty much the same kernel as the enveloping machine and uses also its ram. but the direct interaction between programs run in the container and programs run in the enveloping machine is very limited
 
Hakase
Hakase
oh cool
 
Armin
Armin
@ton.yeung i looked it up, openstack can be used with hyper-v, xen and kvm
i don't think we use hyper-v because i think the server runs some kind of linux
to my previous remark that i don't know what openstack uses and your guess that it is a container and not a vm
oh, vmware can be used as well...
i don't know about routers... but vm and container, yes
ohh, ok
no, openstack does not implement tosca
but iaas platforms can be used with tosca
opentosca implements tosca
i think heat is something different
but the translator is only part of heat
heat is the openstack engine to deploy a container/vm from openstack to openstack easily
with the translator you can also do the same with other deployment methods, like tosca
 
Taisho
Taisho
4:27 PM
 
Armin
Armin
yeah and the only tosca in that article is in autoscaling
like i said, it is used to deploy with openstacks own format
tosca is a different format
the translator can translate tosca to heat
 
Hakase
Hakase
I wonder if documentation.se is gonna have a guide on all of that coz I'd like to read the best practices and figure out what this is best for
among many other things
coz right now this is just theory to me, idk what this is used for specifically
non-playable character or are we talkin about some other mumbo-jubmo?
ok
 
Armin
Armin
except when you run user code...
then you may want to use vms because of added security
 
Hakase
Hakase
how different is it from copypasting a single VM instance that you've installed an OS into and configured everything in?
I think you can run multiple volatile snapshots from a single VM's image
 
Armin
Armin
i think the emulating is far more expensive than copying the disk.
you copy the disk once, but run the emulated os all the time
 
Hakase
Hakase
4:37 PM
so this is for short-term testing primarily?
confusion intensifies
ok so it's basically faster than VMs for your purposes, whatever they are
ok let's stop at this
I don't think I'll be able to understand the game analogy
I have to watch some vids on making actual games tho :p
I'll keep those containers in mind for when I need to do multiple clean tests maybe, but then I'll probably be better off with volatile snapshots if it's just my own computer
 
Armin
Armin
that paper does some comparison between kvm vs vmware
surprisingly (really, i was surprised as well) vmware was in almost all tests better than kvm
well, it shows that at least a kvm container is slower than a vm
i am as well...
but the results are pretty unambiguous.
 
Taisho

Armin
Armin
but kvm utilizes the same kernel as the main os
and vmware sometimes outperforms the main os...
which is pretty weird...
mostly, i only use them as well... but it is still pretty interesting that, with default configuration, a vm might be faster than a container

Q: What is the piano song from Ep 18 13:12 of parasyte?

H.LuffyDoes anyone know the title of that piano song. I have searched a lot and still have not found it.

Q: Amuro Ray in Gundam ZZ why didn't he assist Bright?

LuckyAliWhy didn't Bright ask for Amuro's assistance in Gundam ZZ ,at least in the later parts of the series? What was Amuro doing in the Gundam ZZ time?
