Enterprise Grade Minecraft On Kubernetes - Casey West, Google
Speakers: Casey West
Minecraft runs in a multi-client, single-server architecture. State and configuration are stored on disk. Minecraft servers are network sensitive, CPU and memory intensive, and can only operate as a single instance. It's a great example of Commercial Off-The-Shelf (COTS) software. In this talk we'll take a look at some of the key capabilities in Kubernetes we can leverage to run a high-performance, reliable, and disaster-proof Minecraft server, which you can apply to many other stateful applications your team has to manage. Or just use these techniques to run your own Minecraft server! By the end of this talk you'll understand how to configure high performance storage, manage on-disk configuration, run custom Pod initializations, back-up your state on a regular basis, expose custom service endpoints, and more. We'll take advantage of the flexibility of Kubernetes to increase reliability of software developed by others, not initially meant for a container runtime.
A
A
Alternatively,
did
you
come
here
because
you
have
important
customers
who
play
Minecraft
yeah
I'm,
both
I
have
some
kids
who
are
massively
obsessed
with
Minecraft
and
then
I
also
like
to
play
it
and
for
me
it's
a
resource
management
game.
I
collect
all
the
resources
and
my
children
consume
them
on
the
game
and
then
I
also
use
it
as
a
three-dimensional
programming
model.
So
I
get
to
automate
things
and
that's
super
dope.
A
So
if
you
do
Minecraft,
that's
great
how
many
of
you
came
here
because
you
have
to
manage
commercial
off-the-shelf
software?
That's
provided
you
by
others
with
strange
constraints,
you
don't
always
know
right,
cool,
good,
everyone's
going
to
be
happy,
there's
going
to
be
a
lot
more
of
the
kubernetes
than
the
Minecraft
I
hope.
That's
all
right!
Okay!
A
This
is
my
first
talk
in
in
an
actual
conference
in
more
than
two
years
for
undisclosed
reasons,
but
I'm
pretty
excited
you
can
reach
out
to
me
I'm
at
Casey,
West
everywhere.
I
recently
bought
the
Instagram
handle
from
the
other
person
you
know
and
if
you
do
go
and
follow
me,
you're,
probably
gonna
see
like
hiking
and
rock
climbing
and
stuff
more
than
computery
nerd
stuff,
but
if
you're
into
that,
that's
where
I'm
at
let's
start
with
the
Minecraft
architecture
diagram.
A
A
Obviously,
the
title
of
this
talk
is
Enterprise
grade
Minecraft
on
kubernetes
and
so
I
got
to
to
thinking
you
know.
Is
it
possible
to
run
this
server
on
kubernetes
in
a
way
that's
resilient,
and
we
can
also
do
things
like
you
know,
data
backup
so
that
if
we,
if
we
need
to
recover
the
world
from
a
previous
snapshot,
we
could
do
something
like
that
and
it
turns
out
you
can
so
I
work
for
a
cloud
company.
So
my
my
kubernetes
live
in
in
one
place,
yours
can
live
wherever
they
want.
It
doesn't
matter.
A
This
isn't
a
a
specific
talk
in
any
way,
but
this
is
roughly
what
the
architecture
is
going
to.
Look
like.
You
know
you
so
you've
got
your
client
there
on
the
left,
there's
going
to
be
a
load
balancer
just
in
front
of
an
instance,
so
that's
fun
an
instance
of
This
Server.
If
you're
running
commercial
grade
software,
that's
provided
you
by
others,
the
one
that
I
love
for
work
is
like
s4hana
from
sap
incredible
massive
database
super
performant,
and
there
are
a
couple
of
different
ways
to
scale
it.
A
A
So
another
thing
about
this
piece
of
software
is
that
you
can
do
modifications
right,
so
you
can
install
modifications
on
the
server
and
and
that's
pretty
fun,
how
many
of
you
play
or
know
about
modded
Minecraft.
Yes,
we
really
do
have
a
room
full
of
nerds.
This
is
great
yeah,
so
you
know
I,
like
you
know,
Fabric
and
some
vanilla,
tweaks
data
packs
and
things
like
that
and
I
figure.
I
shouldn't
just
go
and
you
know
curl
them
from
the
web.
A
I
should
do
that,
but
then
put
them
in
a
storage
solution
that
I
control
right
and
that
I
can
also
do
things
like
Version
Control
and
then
I
can
get
them
into
my
into
my
Minecraft
instance.
So
that's
one
thing
we're
going
to
do
with
customizations
and
then
of
course
the
other
big
thing
is
backups
right.
So
how
do
we
do
backups?
A
Well
I'm
going
to
choose
to
to
do
storage
like
super
cold,
like
version
controlled
storage,
it's
pretty
inexpensive
and
I
can
always
pull
out
a
version
from
the
past
and
I
can
configure
that.
However,
I
want
so
so
that's
kind
of
the
plan,
but
it's
a
little
bit.
There
are
a
couple
of
other
little
things
to
point
out.
One
of
them
is,
you
know,
being
able
to
consistently
know
the
address
of
your
Minecraft
server
is
handy,
so
we
need
like
a
static
IP.
We
can
throw
DNS
in
front
of
that.
A
A
A
lot
with
commercial
software,
that's
given
to
us
is
is
that
you
know
usually
we're
required
to
log
into
the
machine
it's
running
on
or
the
the
VM
it's
running
on
and
do
stuff
right,
and
we
we
don't
really
want
to
do
that
for
obvious
reasons,
I
think
for
for
probably
most
of
us
in
the
in
the
kubernetes
world,
in
a
containerized
landscape.
We
don't
want
to
be
logging
on
and
messing
around,
so
we
need
some
sort
of
remote
admin.
A
So
we're
going
to
install
that
as
a
client
and,
of
course,
that
that
requires
a
service
and
a
protocol
so
that
our
clients
can
interact
with
the
the
server-side
voice
chat
system
and
then
for
backups
we're
going
to
use
a
good
old
cron,
but
we're
going
to
do
it
the
kubernetes
way.
So
you
know
that's
going
to
be
the
fun
and
I
have
let's
see
about
a
maximum
of
30
minutes
to
get
into
it.
So,
just
to
give
you
a
heads
up,
I'm
gonna,
I'm
gonna,
go
ahead
and
create
a
cluster.
A
A
So,
let's
start
with
State
Management.
There
are
some
requirements
for
this
particular
piece
of
commercial
off-the-shelf.
Software
I
didn't
write
them
down
because
I'm
a
bad
product
manager,
but
I
am
an
all
right
engineer.
So
you
know
it
worked
out
for
me,
but
one
of
the
requirements
of
Minecraft,
one
of
the
things
to
know
about
this
application
is
that
it
keeps
its
state
on
disk.
So
when
you
create
a
new
world,
a
new
world
is
a
bunch
of
files
on
disk
in
a
directory.
Furthermore,
you
can
configure
your
Minecraft
server.
A
You
can
set
a
bunch
of
parameters
like
am
I
playing
in
creative
mode
or
survival
am
I
playing
on
hard
mode
who's
allowed
to
connect
to
this
server.
What
is
my
white
list
of
those
individuals
who
can
be
an
operator
right?
These
sorts
of
things
that
that
are
important
to
know
and
the
devs
for
Minecraft
have
decided
that
the
the
way
to
do
that
is
on
disk
right.
So
that's
also
on
disk.
All
of
this
is
inside
of
a
data
directory,
so
we
obviously
need
to
keep
that
data
directory.
A
A
If
your
disk
is
fast,
it's
going
to
perform
a
little
better,
it's
also
going
to
perform.
If
you
have
more
CPU
and
memory
or
the
most,
you
can
have
right
so
up
to
a
point
because
Java,
but
but
it's
going
to
perform
pretty
well.
If
you
have
a
lot
of
resources
and
so
I'm
going
to
use
solid
state
disks
and
in
order
to
do
that,
I
just
need
to
set
up
a
storage
class
first
I'm
going
to
call
it
fast
disk
here,
and
there
are
a
couple
of
things
I'm
going
to
do.
A
The
thing
I
want
to
point
out
is
the
reclaim
policy
here
which
is
to
retain
so
if
something
happens
where
this
gets
heated
from
your
kubernetes
state
for
your
cluster,
we
can
retain
this.
The
actual
disk
underneath
so
and
the
other
thing
is,
of
course,
volume,
expansion
and
you're
going
to
see
right
now
that
I'm
going
to
start
with
about
50
gigs
of
data.
That's
a
pretty
sizable
world,
but
if
you
play
the
game
for
a
while,
you
know
that
you
can.
A
You
can
outpace
that
50
gigs
pretty
easily
and-
and
you
want
to
be
able
to
to
expand
that,
but
you
don't
want
to
have
to
pay
for
an
over
provision.
You
know
300
or
500
gigs,
or
something
like
that.
So
that's
one
of
the
things
we're
going
to
do.
The
other
thing
we're
going
to
do
is
set
this
access
mode.
A
So,
like
a
lot
of
again
commercial
upgrade
software
off-the-shelf
software
that
wasn't
designed
to
work
in
a
kubernetes
world
and
sort
of
scale
in
a
in
a
cloud
first
manner.
This
application
runs
one
instance
against
one
set
of
data
right,
so
you
can't
run
multiple
instances
against
the
same
set
of
data.
We
would
run
into
all
the
classic
problems
that
we're
familiar
with
from
the
last
30
or
40
years,
with
disk
based
State
and
multiple
instances
of
our
applications
like
file,
locking
and
reading
and
writing
is,
is
an
issue.
A
So
we
want
to
avoid
all
that
issue
and
we're
just
going
to
say,
read:
write
one's
pod,
so
only
one
pod
can
have
access
to
read
or
write
on
our
cluster
to
this
disk
right.
That's
one
of
the
the
key
things
here
and,
of
course,
we're
specifying
that
we're
going
to
use
the
fast
fast
disk
storage
class,
so
that
allows
us
to
get
away
with
having
our
solid
state
disk
and
we
also
happen
to
have
a
secret
and
the
secret
is
actually
for
that
archon
tool.
A
So
I
mentioned
that
we're
going
to
create
we're
going
to
set
up
the
protocol
for
doing
Remote
Management
of
this
application
and
we're
using
the
archon
protocol
again
valve
open
sourced
the
the
protocol
and
it's
an
open
standard
and
we
need
a
secret
password
to
to
connect
to
it
so
it
this
is
not
a
secure,
password.
I,
don't
recommend
you
using
it!
It
isn't
my
real
password,
yeah
use
it
if
you
want.
Actually
it
doesn't
matter
to
me
all
right
application
deployment.
So,
let's
get
into
this
a
little
bit.
A
This
is
actually
good.
This
is,
of
course,
going
to
be
a
bit
longer,
so
one
of
the
things
here
is
our
recreate
strategy,
so
by
default,
many
of
us
may
know
that
when
we
go
to
update
a
deployment,
it's
going
to
do
a
rolling
deployer.
It's
going
to
attempt
to
do
a
rolling,
deploy,
that's
not
going
to
work
out
so
well
for
us
if
we
have
multiple
things
trying
to
access
this
state
on
disk
right.
A
Here,
here's
a
little
bit
more
of
the
deployment
under
the
specification
here
so
for
our
container
I'm,
actually
standing
on
the
shoulders
of
giants,
this
user
here
who's,
that's
also
his
username
on
on
GitHub
created
a
Minecraft
server
Docker
container
for
us,
which
is
really
handy
and
I'm,
going
to
pretend
that
you
know
in
the
world
of
Enterprise
grade
work.
This
person
is
on
my
team
and
built
me
a
kick
in
Docker
container
and
in
fact
that
is
what
happens
so.
A
A
Hopefully
everybody
knows:
yeah
I
saw
a
lot
of
head
nods.
We
should
we
should
pick
our
versions,
okay,
cool
yep.
So
then
we're
going
to
request
some
resources,
so
in
this
case,
I'm
going
to
request
as
much
CPU
as
I
can
get
and
about
five
gigs
of
memory,
and
this
particular
machine
type
class
I
think
has
six
gigs
of
memory,
so
I'm
leaving
a
little
bit
of
room
for
the
overhead,
but
basically
consuming
it
all
with
this
application
and
I
already
know.
A
You
know,
because
I've
I've
designed
this
solution
that
I'm
going
to
run
one
instance
on
one
machine
right.
One
node
will
run
one
pod
and
that's
it
and
in
fact,
because
again
the
way
that
Minecraft
works,
it's
it's
going
to
be
a
Noisy
Neighbor.
It's
going
to
consume
and
aggressively
use
the
resources
that
you
try
and
offer
it
I,
wouldn't
necessarily
want
to
run
more
than
one
on
a
node.
A
You
know
your
mileage
may
vary,
but
I
would
probably
choose
one
per
node
going
forward
and
then
I'm
going
to
set
up
these
volume
mounts
so
I
mentioned
state
is
managed
on
disk.
In
this
container
image
configuration
that
state
is
at
slash
data
from
root,
so
we're
going
to
mount
our
fast
disk,
our
persistent
volume
claim
into
that
location.
So
that's
going
to
be
how
we,
how
we
keep
our
state
inside
of
this
pod.
So
that's
a
state,
our
stateful
container.
A
The
dev
that
built
our
image
provided
through
environment
variables,
a
bunch
of
ways
to
configure
the
server
I
mentioned
that
we
have
all
kinds
of
configuration
settings
that
we
can
use.
You
can
see
here,
and
this
is
actually
pretty
important
for
Minecraft.
If
you
want
to
tune
its
actual
execution,
is
to
supply
a
bunch
of
jvm
arguments,
I've
I've,
for
the
sake
of
this
slide
and
just
space
I've
cut
out
a
bunch
of.
What's
actually
in
my
configuration
and
I.
Would
you
know
that's
something
you
can
Google
for
yourself?
A
If,
if
you
haven't
when
it
comes
to
running
Java
version
of
of
Minecraft,
but
you
can
see
I'm
going
to
set
the
memory
at
four
gigs
now.
This
is
interesting
because
I'm
I've
provisioned,
five
gigs
for
the
or
I've
requested
five
gigs
for
the
Pod
and
I'm,
using
four
I'm,
giving
myself
a
little
bit
Headroom
here,
just
in
case,
because
I
really
want
things
to
run
smoothly.
A
I
accept
the
end
user
license
agreement
I'm,
enabling
Arcon
and
I'm
also
setting
the
password
through
this
environment
State
as
well
from
a
secret
right.
So
we
set
up
that
secret
earlier
cool.
Okay.
So
our
server
exposes
multiple
protocols
on
multiple
ports
or
multiple
Services,
I
should
say:
Network
Services
on
multiple
ports
and
using
a
couple
of
different
protocols.
So
we
need
to
expose
those
as
well.
A
So
I
already
have
to
do.
Custom
things
with
disk
and
state
I
have
to
do
custom
things
with
ports.
I
can
do
that
with
kubernetes.
It's
really
not
not
that
big
of
a
deal
right.
It's
designed
to
allow
for
that
and
that's
why
I
think
we
can
get
away
with
this
doing
stateful
and
caught
Solutions
on
on
kubernetes
in
a
pretty
pretty
easy
to
manage
way.
A
So
we've
got
voice
chat,
that's
UDP!
We've
got
archon,
we've
got
Minecraft
itself.
These
ports
are
all
default
from
from
the
configuration
of
the
software
directly
and
then
finally,
I'm
going
to
set
up
some
probes
right.
So
I
want
to
know
when
the
server
is
ready.
I
also
want
to
know
if
it's
alive,
so
we're
just
going
to
do
some
probes
to
check
that
sort
of
thing
doesn't
hurt
to
do
it.
It's
a
it's
a
decent
idea,
and
this
is
where
I
had
some
fun.
So
how
do
I
get
my
mods
on
disk
right?
A
How
do
I
get
my
mods
into
the
server
instance
before
it
spins
up,
so
that
it
knows
that
it
has
mods,
and
this
is
a
solution
that
I
came
up
with,
is
is
using
initialization
containers
and
this
is
pretty
pretty
dope
and
you
can
actually
have
an
array
of
them.
So
I
just
have
one
here,
but
you
can
do
another
Dash
args,
Down
Below
and
you
can
have
a
whole
list
and
they
run
an
order
and-
and
so
that's
pretty
neat
because
then
you
can
separate
them
out.
A
So
this
is
the
one
to
install
voice,
chat
and
I've
got
one
for
fabric
and
one
for
the
vanilla,
tweaks
data
pack
and
and
so
on
and
so
forth.
But
you
can
see
here
that
I
am
storing
the
mods
as
jars
in
a
bucket
that
I
can
access
and
I
can
pull
from
and
I'm
just
using
curl
I'm
using
the
curl
image
here
for
this
initialization
container,
so
I,
don't
have
to
initialize
using
the
Minecraft
container.
A
All
I
have
to
do
is
make
sure
I
mount
the
data
directory
and
I,
make
it
readable
or
writable
rather
right.
So
as
long
as
I
do
that,
I
can
actually
write
the
state
into
it
and
I
do
that
before
the
game
ever
starts
up
and
that's
how
I
can
get
my
mods
in
there
now
it
does
this
every
single
time,
I
restart
the
server,
but
I
don't
restart
the
server.
That
often-
and
it's
pretty
fast
and
I-
think
I
think
that's.
A
Okay
and
I
could
optimize
this
with
additional
checks
to
like
bail
out
early
to
you
know,
freshness
or
whatever,
but
but
it's
good
enough
cool,
so
initializing
containers
pretty
neat
all
right
now
service
availability,
so
we
obviously
have
the
Minecraft
service
itself.
So
if
I
have
a
client
and
I
want
to
connect
to
the
server
I'd
have
to
connect
to
some
IP
address
or
if
I
set
up
DNS
it
would
be
DNS.
A
We
also
have
the
voice
chat
which
connects
through
the
client
as
well.
If
the
client
has
that
plugin
enabled
or
that
mod-
and
we
have
the
archon
remote
control
API,
so
we
have
to
set
up
these
services.
So
the
first
thing
that
I
need
to
do
is
is
have
an
IP
address.
This
is
how
I
get
my
IP
address
and
how
I
make
it
static.
You
can
do
it.
A
So
we
have
three
services,
so
the
first
one
is
is
Minecraft.
This
is
relatively
straightforward.
We're
going
to
set
up
the
load
balancer
give
it
the
IP
address
that
we
have
that's
static
and
in
this
case
I
set
external
traffic
policy
to
Cluster
I,
set
it
to
Cluster,
because
I
didn't
mind,
the
Hop
I
think
we
could
do
local
and
honestly
I
didn't
check
it.
So
you
could
do
local
or
cluster
that's
up
to
you,
but
it
is
nice
to
have
the
load
balancer
in
there.
A
So
I
like
to
I
like
to
have
it
and
we're
going
to
do
the
same
for
archon
here,
it's
again,
it's
TCP
same
IP
address
we're
going
to
do
the
load,
balancer
and
finally
voice
chat
so
for
voice
chat.
It's
UDP
which,
of
course,
we
can
do
through
the
load
balancer.
So
no
big
deal
and
same
IP
address
at
services.
So
now
we've
got
the
services
exposed,
but
here's
the
here's,
the
big
one
right.
A
I
just
wanted
to
take
a
snapshot
right,
take
a
snapshot,
throw
it
into
a
storage
bucket.
It's
versioned
and
I
keep
a
certain
number
of
versions.
I
think
I
chose
to
keep
five.
So
that's
about
two
and
a
half
days
of
of
play.
So
essentially,
if,
like
one
of
my
children,
you
know
TNT
griefs,
the
heck
out
of
one
of
my
other
kids
builds
I
I
have
two
and
a
half
days
to
like
make
it
right
right.
So
that's
you
know
my
that's
my
concern.
There.
A
You
know
just
a
backup
Runner,
then
I
had
to
create
a
role
to
interact
with
kubernetes
right,
so
the
kubernetes
API,
so
essentially
I
need
to
be
able
to
get
information
out
of
this
pod.
The
data
is
in
the
Pod,
the
Pod
gets
us
generated.
You
know,
name
with
a
Shaw
and
I
need
to
be
able
to
access
it
in
order
to
run
some
commands
and
you'll
see
why,
in
a
second
and
then
I
have
to
bind
this
role.
These
are
all
pretty
straightforward.
A
There's
no
like
sort
of
fancy
thing
here:
no,
no
magic
necessarily,
but
then
because
I
want
to
store
this
on
cloud
storage.
In
my
you
know,
infrastructure
provider
of
choice
I
have
to
manage
that
as
well.
So
I
have
to
create
an
an
IAM
service,
account
to
interact
with
my
service
or
my
infrastructure
provider,
and
then
I
have
to
add
that
service
account
to
a
policy
that
can
manage
storage
objects.
So
that's
this
right
here
like
be
a
storage
admin.
A
Let
me
do
stuff
with
storage
and
do
it
in
my
project
alrighty.
So
now
we're
at
this
policy
which
allows
you
know
kubernetes
workload
to
do
to
to
have
an
identity
right,
so
we're
going
to
run
a
Cron
job
on
kubernetes
and
that's
going
to
initialize
a
pod
that
pod's
going
to
log
on
to
this
other
pod,
get
the
data
out
of
it
and
put
it
into
the
GCS
object
or
Google
Cloud
Storage
object,
and
in
order
to
do
that,
we
have
to
be
some
some
identity
right.
This.
A
This
application
has
to
has
to
take
on
an
identity
and
I
wanted
to
take
on
the
service
account
for
gcp
in
this
case.
So
that's
a
workload,
identity,
user
here
and
I'm
setting
this
member,
the
Minecraft
backup,
Runner
essay.
So
essentially
it
can.
It
can
be
this
other
service
account
which
leads
us
to
the
Cron
job,
which
I
was
relatively
new
to
when
I
first
set.
A
This
up
I
set
this
up
initially
about
a
year
ago,
I
think
but
I
was
initially
new
to
it,
and-
and
this
is
super
cool,
so
it's
just
like
cron
jobs
of
old.
You
say
you
want
to
run
it
twice
a
day.
I'm
going
to
say
specifically
like
I.
Do
not
want
to
run
this
concurrently
right,
so
I
just
only
want
to
ever
run
one
instance
of
this
thing
at
a
time,
so
I
can,
if
I,
if
my
world
was
massive
and
or
I
was
taking
snapshots
very
frequently.
A
A
Is
the
cloud
SDK
because
I
need
some
tools
to
interact
with
my
infrastructure
provider
and
it
turns
out
you
know:
I
can
just
get
this
super
lightweight,
Cloud
SDK,
it's
running
Alpine
or
it's
on
Alpine
and
then
I'm
going
to
install
these
components
on
gcloud,
because
I
get
gcloud
from
the
cloud
SDK.
So
I
can
get
my
kubernetes
API
interaction
and
I
can
get
my
storage
object
management.
A
A
You
can
also
use
the
CLI
just
like
you'd,
you
know,
use
the
the
kubernetes
API
controller,
API,
directly
or
you'd
use
the
command
line,
and
so
I'm
going
to
turn
off
saving
in
the
game
and
then
I'm
going
to
save
everything.
That's
currently
in
memory
right
get
our
snapshot
snapshot.
It
turn
saving
back
on.
So
there's
a
little
blip
here
where
you
know,
maybe
something
would
glitch
out
and
we
would
actually
lose
some
state
if
people
were
playing
while
it
was
happening.
I
haven't
seen
that
happen,
but
it
could
happen.
A
You
know
it's
it's
a
race
and
then
we're
going
to
use
gsutil
to
copy
that
new
snapshot
into
the
bucket
and
again,
this
bucket
is
just
called
like
archive
storage
that
that
gets
versioned
and
so
old
versions
just
go
away
automatically.
It
cost
me
a
little
bit
extra
in
you
know,
because
I'm
using
a
cloudy
provider
here,
it
cost
me
a
little
extra
to
yank
it
back
out.
A
A
This
is
what
the
backup
configuration
roughly
looks
like
this
is
the
important
bits
that
you
would
need
to
know
again.
I
think
you
can
do
this
on
any
provider
that
provides
this
kind
of
storage
solution.
It's
not
it's
not
unique,
but
the
idea
is,
you
know,
turn
on
versioning
and
you
can
set
retention
policy
to
be
a
certain
number
of
days
or
a
certain
number
of
revisions
right.
So
you
can
do
that
sort
of
thing
all
right,
so
does
it
run
okay?
A
A
So
that's
pretty
cool
by
the
way
I
I
was
here
earlier
than
most
because
I
was
prepping
to
give
this
talk
and
it
felt
like
we
should
have
music
and
I.
Don't
know
how
many
of
you
know
this,
but
if
you
do
play
Minecraft
and
if
some
of
your
constituents
are
are
small
or
fun
there's
a
parody
of
Katy
Perry's,
Last,
Friday,
Night
I
know
it's
on
Spotify,
because
that's
what
I
use,
but
it's
called
Don't
Mind
at
Night,
and
it
is
very
funny.
A
It's
like
I
know,
you're
feeling
kind
of
Brave
and
I
know
you're.
Looking
at
that
cave
and
you're
feeling
kind
of
Brave,
you
know
don't
mind
at
night:
it's
it's
pretty
good,
so
highly
recommended
it's
a
Bop
all
right.
So
what?
If
you
want
to
do
this
for
yourself?
But
you
don't
want
to
go,
find
my
slides
on
sketch
and-
and
you
know,
piece
this
together.
A
Yourself
by
hand
turns
out
the
same
person
who
wrote
the
the
awesome
or
put
together
the
awesome
image
from
Minecraft,
also
put
together
these
server
charts
and
threw
it
on
GitHub
and
that's
actually
what
I
do
use
to
manage
my
instances
and
they
are
great
and
he
has
in
fact
also
done
like
the
backup
management
and
all
that
stuff
for
you.
So
if
you
want
specifically
to
run
Minecraft
and
do
it
in
a
decent
way,
this
is
a
pretty
cool
way
to
do
it.
I
think
and
it
works
on.
A
You
know
on
kubernetes,
it's
it's
not
provider
specific,
but
he
does
have
some
notes
here
and
there,
if
you're,
using
a
particular
provider
and
then
I
did
a
couple
of
things
custom
most,
notably
like
the
storage
class
for
persistent
disks,
because
it's
a
certain
configuration
that
works
with
with
my
chosen
infrastructure
location.
So
so
that's
pretty
cool,
and
hopefully,
through
this,
my
goal
was
to
explain
some
of
the
things
that
kubernetes
has
on
hand
that
I
use
to
run
an
off-the-shelf
piece
of
software.
A
That
I
also
recommend
when
I
talk
to
big
companies
and
and
people
who
are
trying
to
figure
out
how
to
containerize
their
stuff.
You
know
when
it
comes
to
off-the-shelf
software.
The
first
question
is
like:
are
you
really
sure
that's
what
you
need
to
do
and
if
they
are
really
really
sure
that's
what
they
need
to
do?
A
lot
of
these
tips
and
tricks
are
quite
useful
for
a
lot
of
solutions
that
you
have
to
manage.
That
could
go
into
a
kubernetes
cluster
but
need
a
little
finessing
of
the
configuration.
A
A
Now,
just
because
I
I
honestly
was
like
I
can
solve
that
problem.
If
I
have
it
at
least
I
have
the
backups
the
snapshots,
I,
trust
them
and
I
believe
that
I
know
that
my
customer
would
alert
me
to
an
issue
with
this
application
immediately
and
I
would
have
time
to
fix
it.
That's
my
circumstances
may
not
be
everybody's.
That's
a
good
question,
one
last
question:
oh,
we
have
a
question
right
here:
yep
go
for
it
totally.
A
Yeah
now
Minecraft
is
really
important
to
my
family
yeah,
so
yeah.
No
doubt
you
don't
have
to
run
a
four
gig
server
instance
and
again
like
getting
nerdy
about
Minecraft.
Specifically
for
a
moment,
there
are
a
lot
of
mods
that
hyper
optimize.
Both
memory
and
CPU
consumption
there's
also
mods,
that
optimize
network
traffic
and
you
can
get
a
really
high
quality
experience
with
reduced
resource
claims.
A
A
Yeah
totally
awesome
question.
So
the
question
is
this:
is
this
running
24
7,
or
can
you
optimize
it
I
do
not
run
it
24
7.,
because
sometimes
my
children
get
grounded,
which
is
basically
the
same
as
hey
you
know.
Maybe
you
only
need
this
during
business
hours,
like
you
know,
in
in
one
one
time
zone
yeah
you
can
you
can
shut
this
down,
so
I
shut
it
down
just
by
I'm
I'm
super
I.
A
Don't
have
it
automated
I
just
go
and
and
run
replicas
to
zero
scale
right
so
I
just
say:
run
zero,
replicas
or
run
one
run,
one
replica
and
when
it
when
I
run
one
because
I
have
the
persistent
volume
claim
and
it's
and
it
is
persistent,
it
just
pulls
the
world
back
up
and
everything
is
good
to
go
yeah.
That
is
an
excellent
question
yeah.
So
in
this
particular
case
it's
it's
pretty
easy
and
you
could
throw
that
into
a
Cron
job.
A
Yeah,
so
the
backup,
still
it's
still
try
and
they
fail
yeah,
that's
a
good
question
too
yeah,
so
they
fail
because
they
can't
get
the
Pod
ID
and
then
and
then
there's
an
error,
yeah
totally
yeah.
That's
a
good
question.
All
right!
I
really
appreciate
it.
Everybody
it's
a
long,
walk
back
to
whatever
talk
you're
going
to
next.
So
thank
you
very
much
for
coming
down
here.
