during a big technology that's been
emerging in recent years is docker so in
genus 3 we now support docker containers
could you explain kind of what this is
about versus running let's say a VM or
something and why is it cool to have
that in Janissary so first doggy our
containers are much more lightweight
slam VMs yep so you can add lots of
docker containers to your n3 projects
yeah and it's also much faster yep
and what I really like about it outside
this is when you drag a docker container
into your workspace
it connects automatically to internet
yes I suggest we pour the doc your image
from the internet and install it for you
yeah and it's when you saw you when you
drag and drop the document owner into
your project it will work like you don't
have to install anything configure
anything it just you just start the
doctor container usually boots up in
just a few seconds and it's ready to use
now 2.2 great new feature I've heard a
lot of complaints about this big issue
with docker containers you turn it off
you shut down gns3
you open it up again everything that
you've installed is gone yes it's not
the best isn't persistency so now we
have persistency in in gns3 persistent
if I can spell that persistent yeah
constable today so we have persistent
containers terrico persistency of docker
containers in Janissary 2.2 yes I'll add
another video either below I'll link it
below this or it'll be further in the
course depending where you're watching
this showing you how to make docker
containers persistent I think that's a
huge advantage because I had a lot of
complaints on my Python
courses we were used in a boon to docker
container and then they would install
Python and when they come back tomorrow
yes so the the nerd stands alone again
Oh where's my Python program but now you
buy simply it's a simple edit you just
add like the the folders that you want
to keep your assistant and then it
remains yeah it remains so what's the
advantage of using a VM over doc or
would you recommend doctor always if you
just need a few tools like linux shell
with some tools like paying traceroute
Xterra i will go with the care and if
you want like windows in the system or
any other advanced system you just run
it in a in the VM it's if you want a
full operating system yeah if you want
the GUI like the GUI yes like you run it
in a VM the yeah you don't get a docker
windows no no there's no doctor in the
to get a Linux doc yeah yes I mean doc
is more for Linux these days yeah anyway
so if you want like a simple console no
Gino GUI mm and you want to run Python
scripts and that's the way to go yeah
that's a way to good okay is much more
lightweight but if you want to run it
write a Python application with a fancy
graphical user interface and you get a
VM use a VM and the problem the VM is
it's very resource intensive yes so you
cannot like have an resin a VM in your
gen 3 project on your on your computer
but you could with us you could weave
the Carius very lightweight yeah great
any other comments about docker and BM
no no everything
that's brilliant Jeremy Shalini I she'd
this question if I wanted to host a
Windows VM or something that's part of
my genius tree topology how would I do
that you can either use VMware or of
your toolbox
yeah so you got two options here yes you
create your new VM in VMware use our
windows in it within it and then you can
import that VM in Engine 3 in your
journey through project and use it like
so what's the advantage of one of these
I mean I suppose the one thing I can
think of if you running genus the genus
3vm envy my hoo-hoo you can't start up a
whole bunch of VirtualBox VM because
it'll crash the CPU or something Sara
yes is a conflict between VMware and the
Starbucks it's like we around Nestle via
transition support you cannot activate
Nesta to it via traditional support from
both product at the same time yes so in
other words this is something that I've
come across you know I'm running on a
Mac Genius Rima Mac and I'm using VMware
fusion so I have to do my Windows VMs
VMware fusion yes because otherwise it's
gonna crash yeah
so even you're running a junus tree VM
in VMware you have to use VMware VMs who
if you using VirtualBox and you use
VirtualBox VM yes usually it's a good
idea to be consistent yeah so if you
have if you're using VirtualBox VMs in
your projects and you're only running
the j-3 vm in theater box it's the best
- to use both products wrong
sorry we've got a another member of the
team on our time yeah mark Blackwell
himself
can you just flip that back mark so we
can see ourselves okay so the M way if
you be consistent with VMware yes
VirtualBox be consistent work yeah
exactly so you sure endogenous Trivium
with VMware please use gen 3 VMs in your
projects and the same applies to your
third books okay now what about this
because I know you can run Windows VMs
on cume you
you can but it's going to be extremely
slow of the experience not going to be
great so that's why we recommend VMware
of your Tradeworks okay so this option
is basically where you've got the genius
3 p.m. and then you're running cume you
in genus 3 so actually cumulants guess
and then you're running Windows inside Q
inside Linux within the genus 3 VM
running within a virtualization
technology like VMware yeah so your
nesting nesting nesting yes and is going
to be very slow so then you would
recommend these two options VMware
official box for your Windows host or
micro s our store yeah I mean and that's
been my experience I did Kelly Linux and
try to do it this way even with let's
just Linux yep and it's a bit slow so it
seems to be easier sometimes if you've
got big devices or devices that are
going to be process intensive to use it
this way
yeah that's great I mean would you
recommend one of the other or is it just
depending what you're using VM with I
usually prefer to use VMware because
they have a better product yeah things
is they are slightly faster than theater
books but gesture box would be totally
fine to use and it's free that's that's
one of the big advantage yeah that's
great
so Jeremy thanks very much for sharing
about the different appliances if I've
missed any or if there's any that you
have questions about let me know and
I'll create some videos about that
Jeremy thanks very much
