Description
Kompose: The Docker-Compose of Kubernetes - Sebastien Goasguen, Skippbox
Developers who embrace containers start with Docker on their laptop and quickly build a docker-compose file to describe their multi-container application. To deploy this application in a cluster they can rely on Swarm or systems like Rancher. But until now there was no easy way to go from Compose to Kubernetes. In this talk we will present Kompose, a tool that takes a docker-compose file and automatically converts it into Kubernetes primitives. The tool is highly flexible and provides the same functionality as docker-compose, but it also provides extended functionality to embrace Kubernetes powerful API objects. A community driven open-source tool, kompose meets Docker users where they are and brings them automatically to Kubernetes operations.

A
A
Something
about
us
to
start
so,
as
I
said,
I'm
too
much
Karl,
currently
I
work
for
Red
Hat.
In
my
previous
job,
I
worked
at
system
administrator
for
five
years.
I've
been
managing
large
distributed
cluster,
mainly
for
big
data
like
Hadoop,
and
also
missiles
for
container
deployment
and
right
now,
I
work
for
at
hat
14,
where
our
main
responsibility
is
to
create
tools
for
developers
to
make
it
easier
for
them
to
deploy
to
kubernetes
and
OpenShift.
B
A
Okay,
so
because
we
are
going
to
talk
today,
a
lot
about
docker,
compose
and
kubernetes
I
would
like
to
do
like
a
quick
introduction
to
the
dr.
Campos.
What
is
it
so?
Dr.
Campos
is
tool
for
defining
and
running
until
container
applications,
so
it
uses
Gemma.
So
you
have
one
single
file,
an
email
format.
You
can
see
example
on
the
right
side
of
this
slide.
It's
very
simple
example
with
two
containers
they
find
in
docker
compose
and
then
there
is
docker
compose
utility,
so
you
can
run
just
docker
compose
up
and
it's
going.
A
It
will
start
basically
the
containers
as
they
are
defined
in
the
table.
Format
on
your
machine,
but
probably
this
is
really
great
for
developing,
but
probably
sooner
or
later
you
are
going
to,
you
will
want
to
deploy
your
application
in
some
bigger
scale
on
some
orchestration
engine
and
we
one
we
are
here.
So
we
want
to
be
kubernetes
the
tangi.
A
So
this
is
very
composed.
It's
really
handy
because
Campos
spelled
with
K
kubernetes
Campos
and
it's
come
online
intuitive
that
can
convert
Luke
recompose
files
to
kubernetes.
So
it
takes
us
in
docker,
compose
file
on
input
and
converts
it
to
kubernetes
resources,
like
deployments
application
controllers
and
services,
and
then
you
can
and
that
it
can
even
deploy
those
services
directly
to
kubernetes
cluster.
A
So
why
we?
Why
borrow-
and
why
create
conversion,
to
like
this?
So
dr.
Campos?
Yes,
already
quite
big
user
base,
a
lot
of
developers
who
are
working,
create
containers,
they
are
using
the
compose
and
they
usually
like
it,
because
it's
very
simple
and
easy
to
use.
If
you
know
the
current
command,
you
probably
you
can
very
easily
convert
your
doctrine
command
to
kubernetes,
docker,
compose
file
and
start
it
so
plus
there
is
all
there
already
is
a
lot
of
applications
defined
in
docker
compose
file
in
the
compost
format.
A
So
we
wanted
to
bring
all
those
benefits
and
all
those
existing
applications
to
kubernetes
so
which
tool
that
can
convert
the
compost
to
kubernetes.
We
can
bring
a
lot
of
new
users
to
whole
kubernetes
ecosystem
learning.
Kubernetes
resources
can
be
little
bit
hard
because
yeah
it's
they
have.
They
are
much
more
powerful
than
docker
compose
files,
but
for
someone
who
is
just
starting
with
kubernetes
complexity
of
kubernetes,
resources
might
be
able
to
be
submitted.
Intimidate
impede
intimidating
so
compose
can
convert
the
compost.
Files
to
kubernetes
users
can
see
how
different
definitions
in
the
compose
file.
A
Not
everything
in
dr.
Campos
can
be
mapped
to
burn
at
ease,
so
we
started
using
labels
to
annotate
services.
Do
you
get
a
bit
more
information
for
kubernetes
transformation
and
we
will
show
that
little
bit
more
in
our
demo,
so
a
little
bit
about
compose
history?
How?
Basically
this
project
started
so
project
originally
started
in
skip
box,
and
it
was
a
fork
of
fruit
compose
that
composes,
basically
dr.
library,
for
parsing
machine
to
compose
files
via
turd-head.
We
wanted
to
create
similar
project
and
we
didn't
really
like.
A
A
So
about
month
ago,
compose
was
accepted
to
kubernetes
incubator.
It
was
donated
by
steam
box
to
CN,
CF
foundation
and
so
big
signs
here
to
Sebastian
from
skip
box
for
making
all
this
happen.
So
project
is
now
part
of
the
c-cups
and
incubation
process
is
some
championed
by
Eric
Chang
from
Korres
and
sponsored
by
brain
grant
from
Google.
B
Okay,
so
I
like
to
talk
a
little
bit
about
the
architectures
like
we
are,
we
already
reached
dropped
the
code
base
and
we
have
learned
some
contributor
from
great
hat
and
in
Google,
and
the
code
architecture
is
quite
really
really
clear.
We
we
defy
interface
for
for
input
and
they
interpret
for
output
with
the
loader
interface.
Basically,
we
probably
divide
a
load
file
function
that
you
can
implement
with
multiple
input
like
compo
file
or
bundle
file
or
more
in
future,
and
basically
the
loss.
B
5
function
is
kind
of
read,
input,
file
and
mapping
it
to
the
internal
component.
We
divide
and
then
the
the
internal
computer
output,
with
like
a
couple
of
provider
like
kubernetes
or
open
ship.
That's
why
we
divide
the
transformer
interface
with
three
function
and
transform
it
kind
of
mapping
compo
up
to
a
kubernetes
object
or
open
ship
object
or
more
in
future
and
and
deploy
and
undeploy
is
made
of,
and
and
currently
composed,
support,
deploy,
convert
file,
deploy
to
a
kubernetes
by
default,
other
and
open
ship.
B
B
Currently
we
support
dock
Ocampo
version,
one
and
two,
and
so
the
docker
bundle
format
and
to
provide
is
to
output
in
communities
or
OpenShift.
We
have
a
lot
of
issues
actually
I.
There
are
some
interesting
you
see.
We
live
out
here,
for
example,
we'd
like
to
support
my
as
well,
and
we
try
to
every
place.
B
B
B
Also,
now
we
we
don't
support,
build
strategies
in
in
dhaka,
compo
but
yeah.
Why
not?
We
shall
have
it
in
near
future
and
also
because
the
last
ones
very
interesting
that
in
docker
compo
fight
we
can
defy
the
service
without
figure
out
the
port
name.
The
the
pot
but
increment
is
there
already
support
headless
services
when
no
father
presents-
or
at
this
moment
the
the
poor
require
already
Deborah's
is
I,
get
a
little
bit
problem
with
the
test,
but
he
getting
was
strong
variation.
B
Yeah
actually
I,
don't
know
how
to
how
to
say
this,
like
like.
We
follow
the
traditional
versioning,
it's
kind
of
we,
the
last
day
of
release
of
compo,
is
version
0.1
or
to
that
ethene
in
a
Cuban,
editing,
incubator
project,
a
repository,
and
you
can
like
we're
looking
for
a
contribution
from
other
people,
and
you
can
realize
you
can
seeking
the
the
website,
and
there
are
some
interesting
issues
you
you
may
want
to
a
contribute.
B
Have
the
lastest
combo
version
is
0.1
or
2,
and
basically
we
support
three
mains
of
command
convert
up
and
down.
It
met
to
contrast
and
deploying
and
deploy
interface.
We
support
band
or
format
and
local
compote
I.
By
default,
a
provider
like
kubernetes
you
can
expect
to
open
shape
with
does
not
provide
a
oven-safe
I
have
some
demo
application
here.
First
of
all,
be
the
guestbook
application.
B
Can
this
doc
Ocampo
figure
out
the
file,
and
then
we
can
convert
it,
for
example,
and
we
support
different
output
here
you
can
like
compared
to
the
JSON
file
by
default,
or
you
can
figure
out
the
jumbo
format
and
also
the
I
think
I
can
show
them
to
have
here.
You
can
you
can
deploy
by
as
you
can
convert
you,
the
JSON
or
Yammer
or
or
interesting
it
the
ham
shot,
and
we
did.
B
B
B
B
B
It
cries
to
wait
at
this
state.
We
have
to
use
this
flat
because
by
default
we
will
detect
the
file
if
they
they
declare
the
volume
inside
the
doc
Ocampo
of
under
file
that
we
will
by
default,
generating
the
the
PVC,
but
I
will
skip
the
PVC
and
you
the
empty
dear
option,
and
so
I
have
to
figure
out
the
that's,
not
empty
volume,
but
we
will
change
it.
B
Like
we
can
read
the
doc
Ocampo
fly
in
some
complicated
option
like
environment
with
the
colon
or
environment,
with
equal
separator
or
the
pot
with
hot
water
in
container
port,
or
just
only
single
number,
like
this,
even
the
environment,
without
the
value
and
so
okay
and
interesting.
We
add
the
the
compost
pacific
label
like
by
default.
When
you
compose
up
it
will
deploy
to
kubernetes
with
the
service
by
a
cluster
IP
and
as
you
can,
you
have
the
compose
specific
label
to
figure
out.
Soviet
I,
know
port
or
load
balancer.
B
A
A
A
This
is
how
this
applications
look
like
diagram.
So
there
is
a
front
and
that
is
nginx
communicating
with
back-end
the
second
container.
It's
just
simple
go
application
with
REST
API,
and
it
connects
to
the
database
to
MongoDB
that
is
first
container
and
I
have
set
this
up
with
everything.
There
is
like
even
a
persistent
volume,
as
for
persistent
storage
of
the
MongoDB
and
I
have
created
a
kubernetes
cluster
on
GC
on
Google
Cloud
and
go
out
so
I
can
do
just
a
first.
I
will
show
that
it's
very
worse,
even
with
dr.
A
Campos,
so
I
can
do
the
compost
up
and
it
will
start
whole
application.
I
can
just
look
a
host
port
8080,
and
this
is
my
simple
guestbook
application
running
on
my
laptop
using
just
dr.
daemon,
nothing
more.
You
can
stop
it
and
now
with
I,
don't
have
to
do
any
modification
anything
to
dr.
Campos
file.
I
can
do
just
compose
up
and
because
I
have
I'm
already
connected
to
kubernetes
cluster.
A
It
so
deploy
all
three
containers
to
kubernetes
in
check
services,
and
you
can
see
that
from
10
here
there
is
external
IP
pending,
and
this
is
because
this
is
service
with
all
bound
subtype,
because
in
my
dr.
Campos
file,
I
have
used
the
same
label.
The
inertial
view
here
and
I
said
that
I
want
to
front-end
to
be
the
basically
to
have
both
bounds
of
service,
so
we
should
have
soon
public
IP
for
my
front
end
where
I
can
connect
okay,
it's
like
you
know.
B
A
Okay,
oh,
when
you
get
there,
I
will
show
you
bar
so
I.
Don't
think
that
I
can
do
here.
I
can
do
provide
them
open
shift,
I
can't
able
to
open
shift
and
I
can,
as
I
talked
before,
you
can
use
it
like
basic
to
learn
more
about
kubernetes
for
open
shift,
so
we
can
do
convert
I
will
do
a
CD
out,
and
here
I
have
like
everything
that
a
kubernetes
defined
degenerated.
So
I
have
one
service,
there's
a
second
service
for
my
MongoDB
and
around
there
is
deployment
config.
Let's
open
shift
object.
A
A
A
A
A
Yeah
I
screw
up
again
as
a
matter,
so
you
can
see
that
it's
your
deployed
and
you
can
even
see
that
if
I
go
to
storage,
you
can
see
that
there
is
persistent
volume
claim
created
and
currently
it's
waiting
for
purchased.
For
president
this
is
Paris
tank
volume
crime
and
it's
waiting
for
resistant
volume
to
attach.
A
Okay,
since
this
rebuttal
it'll
be
better,
it's
not
working.
Yes,
it's
supposed
to
I'm,
sorry
about
it,
so
yeah
again.
So
to
sum
this
up
basically
compose,
it
allows
your
easily
to
move
from
dr.
Campos
to
component
East
and
it's
likely
great
for
bringing
in
new
users
to
combine
its
ecosystem
and
especially
for
developers,
because
they
know
them
can
very
easily
start
testing
their
applications
on
kubernetes
and
they.
A
A
No,
okay,
so
you
would
like
you
would
like
really
know
your
input
on
this,
so
reset
its
repositories.
Now,
right
now,
in
kubernetes
incubator,
it
helps
/,
Bernice
incubator
such
compose.
We
have
channel
on
kubernetes
like
compose
so
drop
by,
tell
us
what
we
can
do
better,
what
we
are
doing
wrong
help
us
with
that,
and
we
have
also
community
meeting
every
Wednesday.
We
meet
basically
online
and
discuss
things,
so
you
are
able
to
come
to
join
us
and
have
possibly
that
on
tell
us
how
we
can
help
you
with
this.
C
A
D
C
A
B
B
Have
basically,
you
can
also
take
the
bundle
of
I
you?
Can
it
does
that
EAB
or
the
test
bundle
is
okay,
dr.
compo
bundle
and
convert
it,
and
you
figure
out
that
we
want
to
convert
to
hand
chart
then
again
they
take
the
file
and
generate
in
in
the
doc.
Ocampo
bundle
for
a
folder,
and
you
can
take
okay.
B
A
A
A
A
So
question
was
that
on
our
roadmap
we
have
integration
with
mini
cube
and
how
is
it
working
or
so
right?
The
what
we
are
thinking
about
is
to
make
it
really
easily
for
user
that
are
starting.
So
what
we?
What
we
are
thinking
about
is
to
create
basically
that
if
you
do
compose
up-
and
you
don't
have
any
configurations
for
a
cube
city
or
anything
that
will
automatically
use
mini,
cube
to
start
cluster.
C
A
A
Not
rate
we're
asked
because
yeah
this
is
very
useful
in
two
cases,
if
you
want
to
move
start
moving,
so
basically
you
convert
them,
and
you
forget
your
combos
house
and
then,
like
it
technically
yeah
about
that.
There
is
actually
another
project
that
we
are
thinking
about
and
discussing
with
other
people's.
It
cause
open
Campos
and
we
basically
are
thinking
about
creating
another
format
that
is
very
similar
to
dr.
Campos,
but
it
would
be
targeted
to
kubernetes
ecosystem.
So
this
is
where
it
will
helpful
for
you,
because
this
is,
it
will
be.
A
B
A
Yeah
it's,
it
will
be
also
nice,
but
there
is
like,
with
all
those
like
advance,
kubernetes
stuff.
There
is
also
problem
how
to
map
it
to
your
local
compost,
because
there
are
no
such
things
so
every
we
could
do
it.
We
require
labels,
something
as
we
are
doing
with
service
types,
but
it
will
get
complicated,
so
I
don't
know.
