From YouTube: pinephone, pocket & pub ready k8s lab environments for the time-poor CKx student Ewan Nisbet 1.1.6
Description
Because friends don't let friends take raspberry pi's into pubs. As the world (hopefully) continues to open up, who wants to be sat at home / in the office / it's all the same thing?! Or if staying home suits you just fine, novelty is a great way to make learning even more fun.
The Pine64 / PostmarketOS / Mobian / Librem communities are doing great stuff bringing mainline linux to smartphones. A k8s cluster in your pocket is now yesterday's reality. All and every free moment can now be spent studying for the CKx exams, if you have a few hundred pounds spare and the desire to do so.
Having explored the art of the possible with k8s/qemu/stock android more recently Ewan has been doing stupid stuff in the Mobian ecosystem on Pinephone & Oneplus6. A portable way to experiment and explore k8s, CNI deps on kernel names, and more! But let us remember what's key: a k8s lab that is pub ready!

Thanks
josh
and
it's
you
know
great
to
introduce
ewing,
although
he's
his
talk,
I
think
he's
been
designed
to
give
me
a
tongue
twister,
so
I'm
gonna
try
and
call
this
out,
so
it's
ppp8s
pine
phone
pocket
and,
most
importantly,
pub
ready,
kate's
lab
environment
for
the
all
time,
communities.
Ckx
student.

A
Whenever
there's
technology
involved,
there's
always
going
to
be
challenges,
so
just
waiting
for
you
to
come
back,
don't
forget
to
join
us
over
on
slack
again
a
shout
out
to
some
of
our
workshop
sponsors
to
have
a
look
on
kcduk.io.
There
are
a
number
of
workshops
running
through
this
week
from
some
of
our
workshop
sponsors.
A
A
We've
got
some
workshops
run
by
workshops
run
by
jet
stack
by
control,
plane
by
souza,
solo,
io,
container
solutions
and
snick,
some
really
good
ones.
These
aren't
sales
pictures.
These
are
one.
These
are.
These
are
workshops
kind
of
designed
to
help.
You
learn
something
new
kind
of
get
get
hands-on
with
this
stuff.
Some
of
them
are,
you
know,
just
a
couple
hours
investment
and
getting
access
to
some
free
cool
kit,
and
some
people
can
help
you
out
with
that.
So
I
love.
A
Just
while
we're
also
still
waiting
for
you
and
to
come
back,
there
are
some
watch
parties
going
on.
I
I
know
that
they're
going
on
at
the
moment,
so
hi
folks
in
manchester
also
there's
a
couple
of
social
events.
Attached
to
these,
we've
got
the
pub
quiz
later
on
being
hosted
out
of
cardiff,
which
will
be,
which
is
promises
to
be
lots
and
lots
of
fun.
A
C
I
guess
again
we'd
like
to
shout
out
our
sponsors
real
quick
again,
while
we
wait
for
you
and
to
come
back,
our
tech
sponsor
today
that
is
helping
us
with
the
live
stream,
is
tram,
shed
tech
and
we've
also
got
sneak
control,
plane
jet
stack,
systig
and
storage
os,
who
have
all
been
instrumental
in
making
this
day
possible.
So
thank
you
again.
A
Yeah,
absolutely
we
wouldn't
be
able
to
do
this
sort
of
things
without
without
without
those
supporters.
So
please
do
give
them
a
bit
of
love
and
attention,
especially
the
tram
tram
shed
folks,
because
without
this
we
wouldn't
be
live.
So
are
you
getting
on
you
and
great
to
see
you
back?
You
managed
to
solve
your
problems.
B
A
B
All
right
so
apologies
for
the
tongue,
twister
that
wasn't
quite
the
the
intent
of
the
title,
though
it's
good
to
get
some
added
bonuses
along
the
way
right.
So
what
I'm
going
to
talk
about
today
is
some
experiences
I
had
basically
going
through
cka
ck
ad
exams
and
also
trying
to
be
a
bit
more
mobile,
a
bit
more
portable
with
how
how
I
do
that
not
being
chained
to
the
to
the
desk
or
to
a
laptop
somewhere.
B
And
a
topic
or
a
question
that
often
comes
up
fairly
promptly
after
suggesting
this
is
a
this
question
or
a
variation
of
it
right.
So
I
thought
about
it.
I
went
back
and
looked
at
sort
of
how
how
I
got
here-
and
it's
probably
worth
taking
us
through
a
bit
of
a
history
of
what's
going
on
so
like
many
many
things,
this
all
started
as
a
rather
stupid
discussion
over
beers
as
a
works,
drink
somewhere
or
whatever
back
in
2020
q1,
not
that
long
afterwards.
B
We
have
this
this
small
pandemic,
that
a
few
of
us
are
familiar
with
breaks
out
and
that
eventually
leads
into
me
having
my
first,
my
first
staycation.
So
I
got
all
the
buzzwords
so
my
first
covid
staycation
and-
and
I
ended
up
using
that
that
week
for
really
my
own
sanity
I'd.
I
pretty
much
had
enough
of
covid
and
lockdowns
around
q3
last
year,
and
so
we
spent
a
week
having
a
look
at
how
to
get
kubernetes
running
on
top
of
android
on
a
on
a
stock
phone.
B
I'm
not
going
to
go
into
much
of
that
today.
If
people
are
interested
to
to
search
for
it,
there's
a
presentation
somewhere
else
on
youtube.
I
think
it's
london
infrastructure's
code
channel,
if
you
search
for
the
k8s
on
android
and
and
or
my
name,
there's
probably
gonna
bring
that
up,
and
so
I
got
to
got
to
present
that,
and
one
of
the
questions
that
came
out
of
that
session
was
what
would
it
take
to
run
kubernetes
natively
on
the
phone,
and
you
know
that
was
a
that
was
an
interesting
one.
B
B
So
I
got
one
of
those
delivered
and
not
too
long
after
I
got
that
delivered.
We
find
ourselves,
at
least
in
london,
I
think
most
of
the
uk
back
in
lockdown
through
january,
and
so
after
various
sort
of
lab
explorations,
some
of
those
with
the
pine
phone
and
some
of
them
not.
I
managed
to
I
managed
to
get
through
the
cka
and
cka
ad
exams,
so
I
guess
a
selling
point
for
this
talk
is
you
you
might
learn
something
possibly
that
will
help
you
with
that.
B
Certainly
I'll
give
you
a
novel
way
to
do
it
a
bit
later
through
the
year,
because
I
started
to
get
interested
in
now:
sort
of
linux
running
natively
on
phones.
I
ended
up
with
a
oneplus
6t
q,
q2
and
q3.
There
were
sort
of
various
various
continuances
of
this
sort
of
exploration
and
obviously
in
q3.
We
find
ourselves
here
today.
B
Another
question
I
get
is:
why
am
I
hating
on
raspberry
pi?
What's
so
wrong
about
raspberry
pi
and
the
honest
answer
is:
there's
nothing
wrong
with
raspberry
pi
right
I
mean
the
portability
is
perhaps
not
quite
as
good
as
having
a
mobile
phone,
but
there's
a
lot
of
great
things
about
about
raspberry
pi.
You
know
if
you
really
want
to
take
one,
a
raspberry
pi
to
a
pub
plug
it
into
a
usb
power
board.
You
can
do
that.
I
think
the
really
the
main
reason
for
me
not
exploring
that
much
more
was.
B
I
was
already
aware
of
other
people
that
have
done
you
know,
frankly,
some
fairly
cool
stuff.
An
example
here
is
a
twitter
link
to
somebody
who's,
sort
of
come
up
with
a
k8,
raspberry,
pi
set
of
of
nodes
and
a
cluster
that
sort
of
you
can
take
anywhere,
maybe
not
something
I
want
to
put
on
the
bar
with
my
pints,
but
you
know
there's
already
prior
art
here
and-
and
so
I
just
decided,
look
let's,
let's
not
go
we're
competing
with
people
that
are
doing
really
cool
stuff.
B
B
Another
question
is:
why
not
kfreeze
this?
This
comes
up
quite
a
bit.
Obviously,
k
frees
being
a
lighter,
lighter
version
of
kubernetes,
but
again
the
way,
at
least
in
my
mind,
I've
justified
some
of
the
time
I've
spent
on
this
is
being
exam
prep
and
so
really
again,
that's
why
my
focus
has
been
around
k-8s
and
and
linux.
B
So
moving
on
to
these
these
devices
pine
what
so,
it's
probably
fairly
well
known,
sort
of
out
there
now,
but
back
when
I
first
sort
of
caught
on
to
it.
I
was
having
to
explain
this
a
lot
more.
It's
basically
a
give
or
take
200
usd
mobile
phone
that
runs
linux,
natively
fairly
small
sort
of
I
guess,
ram
footprint
or
capability
and
depending
on
which
version
you
get
fairly
small
sort
of
built-in
storage
as
well.
B
B
Another
piece
of
hardware
that
came
along
in
the
day
or
along
the
days
was
the
the
oneplus
6t
so
having
sort
of
explored
a
bit
around
pine
phone
and
started
to
look
at
what
was
what
was
possible.
The
mobium
projects,
which
we'll
come
on
to
shortly
announced
in
in
collaboration
with
some
of
the
is
it
the
one
mark
os.
Basically,
there
was
a
working
kernel
that
meant
you
could
you
could
boot
boots
or
linux
on
the
oneplus
6t
and
the
nice
thing
about
this
device?
B
Is
you
know
the
pine
phones
really
great?
It's
a
really
nice
sort
of
device
and
projects
to
play
with,
but
the
oneplus
is
is
newer
hardware.
So
it's
a
newer
system
on
a
chip.
It's
got
a
bit
more
ram.
It's
got
a
bit
more
storage
built
in
downsides
of
no
sd
card,
but
you
know
there's
enough
to
there's
enough
to
play
around
and
experiment
with
another
sort
of
small
downside.
B
B
So
the
lab:
what
does
what
does
this?
This
lab
look
like
to
give
you
a
you
know
a
bit
of
a
it's,
a
nice
nicer
sort
of
presentation
to
do
face
to
face
and
be
able
to
have
people
sort
of
come
and
say:
okay.
Well,
let's,
let's
look
at
this
look
at
how
this
works,
but
just
to
give
you
a
bit
of
a
taster
for
it
really
we're
talking
about
free
phones
that
top
phone
there,
as
it
says,
is:
there's
nothing
special
about
that
samsung
device!
It's
a
pure
stock,
android
device.
B
The
only
thing
it's
really
doing
is
providing
an
internet
gateway
and
and
a
wi-fi
network
for
the
for
the
other
phones
to
connect
to-
and
I
went
that
way,
mostly
just
for
sort
of
interchangeability
and
portability.
It's
trying
to
make
this
trying
to
make
this
modular
trying
to
make
it
something
that's
easy
to
to
not
be
carrying
lots
of
stuff
around
and
then
the
other
two
devices
on
here
are
just
the
oneplus
that
we
spoke
about
and
also
the
pine
phone.
B
As
I
think
we
spoke
about
before,
and
so
at
the
moment,
pine
have
decided
that
they're
shipping,
all
pythons
with
with
manjaro
and
manjaro's
arch-based
now
k8,
has
been
packaged.
I
went
back
and
checked.
It
looks
like
sort
of
mid-december
k8.
It's
got
package
for
manjaro,
but
what
I
was
seeing
when
studying
and
certainly
trying
to
do,
exam
prep
was
that
really
a
lot
of
the
other
materials
are
debian
based,
and
so
I
was
trying
to
align
myself
with
with
what
was
going
to
work
well
for
the
exam.
B
B
B
The
theory
that
these
coming
into
this
was
that
it
would
be
a
completely
self-sufficient
device
that
could
you
know
you
could
run
linux,
do
everything
you
needed
to
flash
different
operating
systems
and
so
that
that's
another
reason.
I
went
down
that
road.
How
you
set
yours
up
if
you
chose
to
go,
that
way
is
really.
I
guess
comes
down
to
how
much
of
a
how
much
of
a
toy
is
the
device
you
sort
of
use
for
it.
B
B
And
I
guess
to
summarize
some
of
the
gotchas,
so
these
are
arm
devices
right,
so
any
any
sort
of
challenges
you
that
you
face
anywhere
on
arm.
If
you
face,
if
you
face
someone,
I'm
somewhere
else,
you're
gonna
face
them
here,
just
a
again
a
novelty
one,
because
it
was
something
I
was
kicking.
The
tires
on
things
like
doing
an
eks
distro
build,
isn't
possible
at
the
moment,
or
at
least
wasn't
possible
a
few
months
back
using
purely
arm.
B
You've
got
to
basically
build
some
of
that
stuff
on
on
intel
and
then
move
it
across
resource
constraints.
Again,
particularly
the
pine
phone
I
mean,
neither
phone
is
a
super
computer,
but
particularly
the
pine
phone
has
sort
of.
I
guess
an
older
system
on
a
chip.
So
it's
a
reasonably
old
processor
or
a
set
of
processor
cores
and
ram
is
particularly
constrained.
B
Mobian's
got
a
few
quirks
at
the
moment
where
there
are
certain
things
they
do
with
their
kernel,
which
means
if
you
want
to
run
docker,
for
example,
and
in
fact,
if
you
want
to
get
cni's
running
properly
or
at
all,
you
end
up
having
to
recompile
the
kernel
for
for
various
either
kernel
flags
that
aren't
in
there
or
in
the
case
of
the
the
cni's.
And
this
was
an
interesting
learning
for
me.
B
I
hadn't
stumbled
across
anywhere
else,
but
if
you're
building
custom
kernels
make
sure
you
you've
got
the
naming
the
naming
standards
correct,
because
it
seems
at
least
the
two
cni's
that
I
tried
were
expecting
a
certain
standard
and
then
just
won't
run
if
they,
if
they
find
a
kernel
of
a
different
naming
and
the
biggest
one.
I
guess
as
well
is
that
you
know
it's
it's
amusing,
to
build
a
linux
kernel
on
a
on
a
mobile
phone.
B
It's
amusing
as
long
as
you
can
put
the
device
down,
walk
away
and
ignore
it
because,
let's
say
it
takes
a
number
of
hours
and
so
particularly
where
I've
been
working
with
the
the
oneplus
I've
for
the
most
part.
I
have
I've
sort
of
cheated
right
and
cross-compiled,
because
I
just
wanted
to
get
stuff
done
in
a
relatively
timely
manner,
particularly
as
you're
exploring
and
sort
of
finding.
You
need
to
rebuild
kernels
a
few
times
because
of
various
settings.
It
starts
to
get
a
little
bit
tedious
and
another
another.
B
This
this
device
can
run
quite
hot
if
you,
if
you
leave
it
compiling
for
a
while,
and
I
have
actually-
I
have
actually
picked
it
up
and
thought
do
I
do.
I
really
want
to
walk
away
and
leave
that
somewhere
and
with
the
the
temperature
it's
getting
to
do.
I
have
I
have.
I
got
the
right
insurance
for
my
house
at
this
point
or
or
do
I
want
to
do
something
else,
so
it's
definitely
something
only
from
a
safety
point
of
view
too.
I
just
keep
in
mind.
B
So
just
coming
back
into
pine
phone
and
some
of
the
things
in
case
folks
are
thinking
and
looking
at
this
one.
One
of
the
things
I
went
into
this
thinking
was
you
know:
can
I
make
this
a
daily
driver
it'd
be
really
nice
to
have
a
native
linux
device,
no
no
sort
of
third-party
things
on
there,
no
sort
of
google
play,
or
things
like
that
can
I
run
just
a
pure
linux
device
and
and
personally
I've
reached
a
conclusion
that
not
yet
it's
a
really
really
great
project.
B
But
personally,
there's
just
a
few
and
they're
quite
small
sort
of
things
that
that
I
think
you
know
could
be
can
be
ignored
depending
on
what
you're
doing
with
it,
but
from
a
daily
driving
point
of
view
and
just
sort
of
silly
little.
Things
like
the
usb
connector
isn't
isn't
the
the
greatest
the
greatest
solution
that
the
port
tends
to
for
most
of
the
either
cables
or
docks
that
I've
got
doesn't
connect
very
well
and
charging
the
battery
doesn't
work
very
well
when
you're
docked.
B
So
for
the
purposes
of
I
guess
sitting
in
the
pub.
That's
not
too
big
a
deal
right.
If
you're
you
take
the
device
out,
you
use
it,
and
then
you
charge
it
when
you're
back
home.
But
if
you
try
to
do
anything
sort
of
with
the
convergence
mode,
then
that's
yeah,
you
start
to
run
into
sort
of
annoyances.
B
And
lastly,
just
as
a
simple
thing,
you
know
one
of
one
of
the
ways
I
have
used.
These
devices
is
to
sit
down
and
sit
somewhere.
I've
got
a
spare,
I
don't
know
anywhere
between
five
and
35
minutes,
where
I'm
somewhere
away
from
my
computer
or
away
from
my
desk.
I
want
to
just
go
and
explore
something
read
up
about
something
experiment
with
it.
Some
of
my
experiences
with
web
browsers
on
pine
phone
has
just
been
a
little
bit
less
than
I've
managed
to
sort
of
work
around.
B
So
if
you
wanted
to
go
this
way,
which
device
would
you
choose
and
of
course
right
it's,
then
it's
depends
answer
that
nobody
ever
gives
you
a
straight
answer
these
days
and
I'm
certainly
not
going
to
break
the
mould
with
that
today.
So,
depending
on
whether
you're
looking
at
cost
depending
on
whether
you're
looking
at
you
know,
small
things
for
a
phone
like
does
phone
crawling
actually
work,
it
really
depends
which
way
you,
which
way
you
would
you
would
go.
B
I
guess
I'm
talking
about
android
operating
system,
development
and
evolution,
and
you
know
you're
you're,
happily,
flashing
phones
as
as,
and
when
then
probably
these
things
don't
matter
for
me.
Coming
to
this
is
a
you
know.
The
real
purpose
is,
I
want
to
study.
I
want
to
learn.
I
want
to
learn,
kubernetes,
internals
or
better
learn,
kubernetes
internals
and
things
like
that.
The
sort
of
barrier
to
entry
on
pine
phone
was
was
a
bit
a
bit
lower.
B
I
felt
and
yeah
I
mean
theoretically,
you
you
could
use,
could
use
the
pine
phone
as
the
as
your
only
device
and
you
know,
run
run
your
kubernetes
cluster
connect
it
to
a
screen
if
you
really
wanted
to
or
and
sort
of
browse
what
you're,
what
you're
reading?
What
you're
studying
that
sort
of
thing
on
one
device.
B
And
that's
all
I'm
going
to
run
through
today.
I
thought
because
I'm
not
doing
a
demo.
The
best
thing
to
do
is
really
sort
of
whizz
through
here
share,
share
some
of
the
highlights
or
highlights
and
learnings
that
I've
had
along
the
way
and
yeah
just
open
things
up
to
answer
questions
as
to
if
people
are
interested,
they'd
like
to
know
more
and
and
yeah
go
from
there.
A
If
anyone's
thanks
like
that,
you
and
that's
what
that's
awesome,
that's
really
interesting
project.
If
there's
anyone's
got
any
questions
feel
free
to
either
ask
in
in
youtube
I'm
pointing
at
my
screen,
which
I
know
you
can't
see
youtube
over
there
slack
over.
There
feel
free
to
ask
a
question:
either
location.
If
we
don't
get
a
chance
to
get
to
it,
live
now,
I'm
sure
you
it'll
be
around
later
on
either
on
slack
or
on
twitter
or
whatever
yeah.
B
So,
generally
speaking,
I've
not
used
any
bluetooth
devices
at
all.
However,
the
the
I
guess,
one
of
the
key
points
about
the
convergence
model
of
the
pine
phone
is
that
it
comes
with
a
dock,
which
means
you
can
connect
a
as
it
happens.
A
raspberry
pi
keyboard
and
a
raspberry
pi
mouse,
and
you
know
you've
then
got
the
choice
of.
Is
your
eyesight
good
enough
and
you
want
to
use
that
tiny
little
screen,
or
are
you
actually
just
going
to
connect
it
up
to
a
real
real
screen?
B
Where
you
can
see
what's
going
on
and
get
things
done?
I
think
for
me,
a
lot
of
the
usage
has
been.
I.
I
typically
find
myself
with
a
little
bit
of
downtime
when
I
suddenly
think
what
about
x
and
it's
really
nice
to
just
go.
Oh
I've
got
this
thing
in
my
pocket
and
I
can
I
cannot
go
and
look
at
the
manual.
B
I
can
go
and
execute
the
command,
and
you
know
within
certain
boundaries
it
will
run
one
and
it
will
tell
me
what
the
output
was
and
why
I
got
it
wrong
and
that's
really
that's.
When
I've
put
up
with
the
the
little
keyboard,
because
yeah
I
mean
that's
fun
right,
it's
a
nice
novelty,
it's
quite
amusing,
but
the
second
or
third
minute
of
that
gets
a
little
bit
frustrating
as
you
go
along.
A
B
Yeah,
so
I
mean,
interestingly,
the
convergence
mode
and
there's,
if
folks
want
to
go
and
look
at
it,
there's
various
sort
of
articles
about
why
it
is
the
way
it
is,
but
the
convergence
mode
prevents
fast
charging.
So
it's
actually,
if
you're
using
the
dock,
that's
when
the
battery
drain
starts
to
happen,
and
it
you
know,
depending
on
what
you're
doing
you
can
mostly
keep
sort
of
a
steady
state
of
battery,
but
I
think
the
challenge
for
most
people,
at
least
for
me,
is
when
you're
when
you're
docked
somewhere.
B
You
expect,
if
it's
charging,
because
you
expect
it
to
then
walk
away
and
work,
and
when
you
get
a
different
experience,
it's
just
a
bit.
Yeah
you've
got
to
factor
that
in
if
you
were
doing
a
lot
with
it
as
a
as
a
sort
of
a
novelty
devoid
a
novelty
and
something
you
use
remotely
and
don't
necessarily
sit
and
use
docs
it
work.
It
charges
perfectly
fine
and
works
really
well.
A
Awesome.
Thank
you
very
much
for
that.
I
know
we're
we're
about
10
minutes
early,
but
but
on
the
flip

community
and
wider.
A
So
it's
not

others
that's
what
stem
stands
for.
So
please
do
come
back
for

One
we'll
be
