Description
Guest Speakers: Alban Crequy of Kinvolk.io and Ilya Dmitrichenko of Weave.works
In an OpenShift Commons Briefing last May, we demoed a prototype of using Weave Scope on OpenShift to do traffic shaping; limit bandwidth, drop packages, change latency. Since then, Weaveworks and Kinvolk worked together to make this available as a proper Scope plugin (https://github.com/weaveworks-plugins/scope-traffic-control).
This time around, we’ll demonstrate the outcome of that work. Specifically, we’ll introduce Weave Scope and look at its plugin architecture, demo a few of the plugins that are currently available, and see how Scope plugins can be installed on OpenShift.
We’ll use the microservices-dem (https://github.com/microservices-demo/microservices-demo), Sock Shop, to see an example of how traffic shaping is useful for testing. Finally, we will introduce you to some of the katacoda (https://katacoda.com/) guides available on the Weave website
(https://www.weave.works/guides/) where you can test out and learn more about Weave Scope.

Hello,
everybody
and
welcome
again
to
the
open
shift
common
is
briefing
today
we're
having
a
reprise
back
in
May
of
last
year.
I
think
it
was
Alvin
creaky
of
kin
folk
was
here
demoing
a
very
early
version
of
their
integration
for
traffic
control
in
with
leaves
coats
and
from
leave
work
and
he's
back
again,
they've
made
it
an
official
plug-in
and
going
to
demo
it
and
show
some
of
the
new
stuff
you
can
do
with
it.
So
there
are
a
few
folks
from
we've.
A
Also
joining
us
and
the
format
for
this
today
will
be
almond,
mocha,
Zia's
talk
and
it's
demo.
You
can
ask
questions
in
the
chat
and
we'll
try
and
answer
them
and
then
any
of
the
good
questions
we'll
ask
out
loud.
So
they
get
reported
the
answers
and
then
we'll
open
up
for
Q&A
at
the
end.
So
without
any
further
ado
album,
please
take
it
away
from
boring.
A
B
You
I
welcome,
so
we
talked
about
the
second
cohort
in
together
on
I
can
be
used
to
take
this
application
with
a
web
application,
but
I
will
stop
to
present
myself.
I
am
alone
on
my
contributed
to
look
at
another
remark.
I'm
working
on
50
BPS
on
a
few
years
ago.
I
worked
on
a
couple
already,
but
the
thought
defense's
case
it
was
found
it
immediately
kitchen
sink
up
from
the
table
for
you
today
we're
using
forgive
traffic
controller,
I,
deep
as
well.
Our
web
application
for
the
micro
service
and
I
were
casting
fault.
B
B
As
I
said,
it's
camera
do
the
stock,
but
let's
hang
on
an
emoticon,
solid
12
and
click
community
uncle
stage
the
image
of
our
content
plus
night
of
the
lead-
into
it
come
so
I
will
show
we've
got
with
from
the
mode
using
an
application
called
the
function.
It's
a
web
application
developed
by
two
companies,
consolidation
and
we
work
on
user
microservice
GTG.
B
I
will
show
her
to
eat
all
that
are
going
to
cut
whistles
cut
on
her
cheek
and
what
they
are
secure
and
then
I
will
show
the
plug-in
and
the
traffic
control
plug
in
how
to
use
it.
I'm
successful
unhappily
other
shoe
another
beginners
learn
with
Scott
and
had
the
other,
which
shows
among
guys,
that
we've
worked
on
the
website
and
using
liquid
up,
though
we'd
rock
fan
I,
we
stopped
with
showing
anything
from
the
be
quit
my
slide
on
three.
I
will
show
you
my
setup.
B
B
To
the
photo
namespace
that
I
created
in
the
budget
and
I
have
two
new
kernel
space
so
that
created
at
the
bottom
naksh
optimal
allocation
and
risk
of
we
rise
to
the
code
for
home
mom,
showing
you
God
for
that
that's
review
of
other
coconut
running
on
microphone,
and
here
I
am
under
thought
you
for
the
purview.
It's
wicked
empty
spot
is
opening
one
or
not
container
image
on
what
interesting
here
is.
I
can
see
the
communication
between
the
phone
pugna
funny.
B
Webshop
we
are
people
combined
folks
on
a
different
page
and
we
quickly
go
through
them
and
the
home
page
and
the
catalog
can
page
and
each
of
those
is
a
different
continents
online.
When
I'm
clicking
on
firefox
here,
I'm
talking
the
50
feet
talking
to
the
front
and
company
that
the
entity
the
frontal
container
is
talking
to
you
can't
connect.
So
let's
go
back
here
and
since
I
kick
it
kick
a
bit
on
a
web
page.
B
The
finale
established
communication
with
others
of
enough
on
a
seasonal
I
have
a
middle
way
to
see
the
architecture
of
my
application,
but
I
think
easier
to
win
that
way.
10-12
just
released
after
contain
a
street
map.
Another
thing
I,
like
is,
we
can
have
a
higher
value.
So
here
is
a
list
of
pot,
but
we
can
I
see
the
email
Arabella
signal
to
relative
decline
on.
B
B
So
how
high
in
front
of
an
open
seat
to
the
lab
which
are
separated
was
to
create
project
another
cheat
or
communities
near
space
at
the
college?
Visco
I
use
the
blue
ink,
among
whom
credit
with
the
holy
command
line
tool
without
a
new
project,
fiscal
and
then
I
can't
wait.
Some
say
village,
because
I
want
the
container
opening
with
copper
coil
privileged
to
be
able
to
eat
all
the
profit
on
the
north
to
list
other
professional
connections
funny.
B
He
cannot
just
leaving
this
one
Caligula's
need
to
have
access
to
reversing,
to
be
able
to
inspect,
what's
happening,
no
problem,
so
I
need
to
give
the
privilege
capability
to
read
scope,
project
and
exact
without
us
a
comment
and
then
I
what
we've
got
to
have
access
to
the
connectivity
I
so
that
they
can
expect
you
can't
ask
academic
is,
was
after
distance
of
the
distance,
this
undulating.
So
how
do
that
as
well
with
already
increment
and
I,
give
the
white
of
weight
wide
access
to
the
calamitous
ck
all
sigh
product?
B
This
ability
is
no
space.
I
installed
Scott
for
forgot
to
get
the
Yemen
file
and
we
quickly
show
you
other
should
like
go
under
with
works
webpage
on
scope.
There
is
literally,
are
selling
it,
but
what
we
won't
hear
it
the
twist
rate
of
calamities,
but
we
can
get
this
image
file,
which
decides
the
young
coconut
used
in
wisco
and
with
that
become
just
a
solid,
using
fiber
bundle
secret.
B
B
God
has
a
motion
that
capacitor
component
there
is
one
component
called
scope
up:
that's
what
fireworks
images
is
talking
to.
So
let's
provide
the
22
value
of
all
the
containers
to
the
user,
but
we
get
the
shot.
Information
from
the
scope,
agent
and
cottages
is
recommended.
That
means
sediment
onion
one
time
when
every
node
and
that
what
will
fetch
the
rest
of
process
list
of
connection
the
little
parts
etc
on
which
number
under
the
cup
agent
is
also
called
the
pole
by
the
way
and
its
funding
report
to
Europa.
B
B
I
had
it
something
in
the
club
yeah
and
if
you
see
if
I
haiku
page
is
not
going
to
be
strong
management,
it's
not
that
bad
and
it
seems
to
work
fine.
But
actually
there
is
some
UI
problem
that
are
difficult
to
see
for
developers
were
usually
a
good
internet
connection,
but
one
in
the
is
critical
activity
program
is
more
difficult
to
see
the
photos
of
opening,
so
I
wish.
You
were
down
in
the
front
one
now.
Has
it
clicked
it
to
the
catalog?
B
However,
what
a
parish
and
had
a
lot
of
certainty
to
the
category
personnel,
so
here
I
click
on
catalog
for
a
CW
circles.
Well,
and
actually
we
won
in
the
dressing,
11
2012
and
then
the
traffic
also
pegging
in
today's
tolerance
Club.
By
the
way
you
can
see
at
the
bottom
add
my
chicken
with
I
not
forget.
This
was
big
in
the
title
and
heat
added,
some
coals
on
the
UI
to
change
the
latency,
but
he
had
leaked
indeed
and
in
effect
a
superficial,
but
I
suppose,
to
have
to
feed
on
latency
and
is
advocate.
B
B
You
can
see
here
on
the
plug-in,
and
so
that's
why,
when
you
delay,
is
a
packet
by
to
Saddam
making
a
lobster
follow
the
good
what
you
can
do
with
that
is.
When
you
refresh
you
can
see
what
other
me,
you
can
feel
that
the
shopping
cap
appear
to
be
empty
under
the
bed
in
a
riot
of
not
supposed
to
be
like
that
to
life.
Show
that
something
is
in
loading.
B
B
B
Click
on
green
Haskell
hook
up
the
under
part
of
the
main
project
down
additional
capacity.
Here
you
can
see
the
little
treats
on
her
we'd
work,
Costigan
pleasure
of
traffic
control,
and
here
you
can
fetch
the
game.
In
fact
that
you
can
use
to
Toronto
bandages
on
Danny
chemical.
We
are
key
with
OC
or
chips
additional
on
how
it
works.
Can
the
plugins
are
demoted
and
all
that
means,
as
they
were
known
in
one
copy
of
each
node
and
then
the
eject
undeterred.
B
B
Positively,
welcome
and
unique
forget
so
if
plugins
will
create
a
unique
forgetting
that
directory
and
then
the
agent
with
our
European
a
directory
on
tour
20,
a
very
well.
That
means
the
director
is
shared
by
mountain
between
cottages
on
begins
now
to
protocol
seguin
coca-cola
actual
interface
went
to
Hopkins
96
on
want
to
have
a
mark.
He
returns
to
not
report,
and
if
you
want
to
develop
computing,
we
can
do
that.
You
can
follow
the
between
the
sooner
we
show
you
I
choose
back
here
and
hungry
was
website.
B
B
B
B
It
exists
in
a
non
terminal
in
Linux
since
remix
to
that
too,
and
that
network
schedule
all
that
you
can
install
on
a
network
interface
and
then
you
can
configure
different
properties
like
the
point
with
and
then
I
can
see
on
to
fake
a
bunt
on
a
catcher
I
want
to
coat
pocket.
Mr.,
the
lots
of
different
monitor
you
can
play
with
in
this
demo.
I
only
play
with
latency
occur,
want
to
add
to
federal
agency
or
a
to
each
packet
I'm.
B
Not
what
about
using
from,
but
I
don't
want
to
change
the
latency
of
everything
and
my
laptop,
because
I
was
otherwise
todo,
medium,
chronic
or
other
thing.
I
want
to
configure
the
network,
the
network
little
onion
specific
enough
on
each
container
of
general
network
interface.
So
if
you
cook
together
on
doing
the
subpoena
on
specific
30
Dodgers,
then
that's
ok,
only
the
singing
that
container
will
be
affected
by
changes
configuration.
So
in
this
case,
I
was
offended.
Traffic
on
for
dinner,
Scott
actually
configure
the
network
interest
of
specificity.
B
B
So
I
ever
coming
on
here
and
I
are
on
a
shelf.
It
is
a
secret
in
that
loop,
but
connecting
to
this
URL
and
repetitively
connected
fetching
a
web
page.
So
while
I
have
that
running
in
the
background,
I
will
go
back
to
sculpt,
actually
and
I
will
infect
the
front
on
my
comfy
now.
So,
let's
see
from
hong
kong
a
girl
a
shoulder
inside
the
list
or
process.
B
B
B
So
here
are
the
data,
but
three
HTTP
request
a
freedom
I'm
about
the
same
of
a
CPL
response:
amateurs
HTTP
to
android
platform.
That
means
everything
is
ok.
Actually
try.
Look
it
correctly.
So
after
that
I'm
I
have
another
pet.
Have
Republican
mayor
URL.
As
you
complete
a
quest,
you
nt2,
don't
refer
to
anything
each
will
vote
on
over
40
and
whenever
needed,
loop.
It
don't
notified
about
the
commercial
world
is
also
a
rock.
So
let
him-
and
after
the
last
word,
Kakashi.
B
If
you
have
to
equip
with
volume,
we
see
the
different
class
on
the
temp
you're
here
close
the
rigidity
statistics
but
are
in
fact
I
can
show
you
the
view
right
here
at
the
bottom.
Here
you
see
the
difficult
but
I
consider
on
if
you
earn
in
space
I,
consider
the
needs
bed
the
bills
of
a
lot,
because
some
ricotta
nerves
are
samples
from
work
until
condoms
from
with
with
scopes
and
from
Oxford,
an
extra
hitter
on
an
elite
club.
B
Okay
for
to
infer
the
HTTP
design,
a
statistic
come
in,
it's
bracing
it
out
of
the
20
control
one
you
go
to
the
webpage
to
get
the
Yemen
file
economic
image
file
and
then
include
that
will
not
purchase.
It
amounted
to
one
pod
on
each
node.
That
will
give
the
information.
So
how
does
it
actually
work
already?
Keep
the
statistics
as
a
bit
more
complicated.
It
use
the
pair
program
so
for
that
I
need
to
talk
a
bit
about
the
camel
what
apartment
when
I
get
sardines
on
between
process.
B
So
there
is
a
kernel
function
called
skb
copy
that
parameter,
which
is
called
every
time
with
copy
a
buffer
to
to
forget
twisted,
especially
progress
on
what
the
HTTP
HTTPS
exhibitionistic
beginners
is
one
EDD
program
attachment
via
campus
to
this
common
assumption.
That
means
not
difficult
dysfunction
in
the
cannon
to
executing
it
will
trigger
verification
of
diabetes
program
on
the
EBT
fom.
B
We'll
have
a
look
at
the
prefer
to
see
what's
inside
the
packet
and
if
it
looks
like
a
HTTP
request,
that
means
that
the
keyword
get
or
thurs
or
delete
or
similar
or
if
you
took
secure,
HTTP
weapons,
then
it
will
never
get
valuable,
especially
in
Rajab.
It's
a
hash
table
so
that
forgiving
is
torn
between
the
tea.
That's
the
progress
on
the
compressed,
which
is
a
hominid
HTTP
real
cuz.
B
There
is
many
HTTP
response:
ET
peut
etre
in
the
Bible,
which
is
shared
between
the
camel
in
the
negative
column,
invisible
in
HTTP
provision
and
regularly
the
HTTP
begin.
We'll
have
a
look
at
not
come
back
to
know
how
many
requests
on
da
and
then
it
will
be
able
to
from
that
to
the
legend
and
to
install
that
EBV
program.
The
penis
does
that
the
fanatical
c
function
which
is
compiled
on
the
fly
by
resorting
to
a
psi-cop
and
interpreted
in
the
kernel
installed
with
the
caper
bondage
function.
B
B
C
B
B
A
So
while
he's
doing
that
it
from
the
other
folks
who
are
not
on
the
call,
if
any
of
you
have
any
questions,
raise
your
hand
and
the
chat
and
not
on
you
and
you
can
ask
them-
and
it's
quite
a
couple
of
you,
I
recognized
as
having
large
production
deployments
of
open
shifts
and
I'm
curious
to
hear
how
you
manage
monitoring
and
testing
traffic.
Doing
this
sort
of
traffic
control
work
currently.
And
if
any
of
you
are
already
using
these
soap.
A
B
I
can
continue
it
go
so
icky
can
link
are
now.
If
you
work,
I
can,
after
just
a
couple
of
things.
I
can
I
have
academic.
If
you
Sarah
can
type
from
Capitola
man
and
I
can
deploy
thing
by
just
clicking.
We
do
first,
the
truck
shop
demo
on
it
will
be
given
and
I
can
have
a
look
at
this
page
to
see
on
religion
in
October,
Napa
and
I
can
it'll
Scott
checking
account
type
90.
A
A
A
If
anyone
who
are
listening
in
right
now
or
listen
later,
if
you're
already
using
week
so
15
tested
the
traffic
control
plug
in
on
your
production
environment
already
so
I'd
love
to
hear
from
you
either
email
or
the
commons
mailing
list,
and
that
would
be
great
to
get
to
feedback
on
the
plug-in
and
any
insight
you
have
to
share
with
kinfolk
and
levon
on
that
effort.
So
please
do
if
you're,
using
in
production
or
thinking
about
it
or
have
a
few.
The
wii's
cloud,
katakana
stuff
looks
great
