Library Charts New to Helm 3 Martin Hickey, IBM
A
Good
morning,
everybody
welcome
to
day
two
as
matt
said
earlier.
My
name
is
Martin
Hickey
and
I'm,
a
developer
at
IBM
and
I'm,
also
a
core
maintain
or
in
in
the
helm
project.
So
I'd
like
to
talk
to
you
today
about
library
charts,
which
is
a
new
capability
we
introduced
in
helm
tree
so
you're,
probably
all
looking
forward
to
hell
tree.
A
So
it's
good
to
we're
being
able
to
talk
about
some
of
the
capabilities
leading
into
it
before
it
goes
GA,
so
just
brief
kind
of
agenda
and
what
we're
going
to
look
at
we're
going
to.
First
of
all,
talk
about
common
charts
which
are
already
available
in
hell,
m2
and
then
we're
going
to
start
talking
about
library,
charts
and
hell
tree
I'll
do
a
demo
to
to
show
the
capability
and
then
we'll
just
wrap
up
on
it.
A
So
in
this
situation,
what
normally
happens
is
we
basically
create
the
different
sub
charts
and
we
have
duplication
across
some
of
the
sub
charts?
Now,
why
would
you
of
situation
like
this?
Oh
I,
don't
know
maybe
so
chart
one
is
possibly
a
sub
chart
defined
in
a
database.
Such
a
tree
might
be
for
a
web
server
or
something
like
that
and
you're
you're.
Looking
at
it
saying
right.
This
is
great.
You
divide
it
up
into
different
components:
you're
using
your
umbrella
chart
to
deploy
it.
A
But
when
you
look
at
this,
you
say:
wouldn't
it
be
great
if
we
could
avoid
this
duplication,
if
we
could
implement
a
draw
principle
so
that
at
least
we'd
have
an
in
one
central
point
and
we
may
change
is
then
and
when
we
include
afterwards,
then
we're
not
doing
it
in
more
than
one
location
in
hellim.
We
have
such
a
situation
with
such
capability
to
do
this,
and
this
is
the
common
chart.
A
So
the
common
charts
concept
came
from
a
chart
developed
by
Mac
butcher
and
probably
other
people
as
well
in
it,
and
he
made
this
available
in
the
incubator,
repo
in
the
helm,
repository
and
what
it
does
is.
It
gives
you
some
basic
capabilities
of
kubernetes
resources
like
your
deployment,
your
service,
your
ingress,
etc,
and
what
it
does
is
it
allows
you
to
pick
up
those
capabilities
and
then
override
or
extend
the
differences
that
you
may
have
from
the
base
capability.
A
So
you
can
see
here
in
the
diagram
that
no,
the
sub
charts
no
extend
also
from
the
common
chart
here
at
the
bottom
in
yellow,
and
you
can
see
here
that
I've
highlighted
two
things
on
us.
First,
one
is
common
deployment
and
you
common
service,
and
in
this
situation
these
are
keys
so
they're
an
example
of
a
key
where
you
define
the
particular
capability
in
this
situation
for
common
deployment.
A
What
you're
doing
here
is
you're
you're,
basically
defining
a
basic
deployment
resource
object,
a
manifest
and
the
same
for
the
service
and
what
you're
doing
in
in
sub
chart
one.
You
can
see
no
you're,
basically
including
this
and
then
all
what
you're
doing
is
adding
the
volume,
because
this
is
the
extra
capability
you
want
and
then
you
can
see
in
sub-tree
the
same
thing
again
you're,
including
the
key
for
common
deployment
and
comment
that
service.
So
what
you're
doing
here
is
you're
centralizing,
you're
doing
reuse
and
you're
also
enabling
the
Detroit
pattern.
A
A
So
when
we
looked
at
this
capability
in
the
commune
in
the
community,
we
said
a
couple
of
issues
kept
coming
up.
One
of
them
was
and
you'd
see
from
time
to
time
is
that
somebody
forgot
he
was
a
laborer
chart
and
decided
to
install
it
okay
and
because
we
had
no
capability
to
distinguish
between
a
common
chart.
The
only
way
we
distinguished
between
a
common
chart
and
an
application
chart
was
if
there
was
release
artifacts
in
it.
Okay,
so
if
it
had
to
release
artifact,
then
yeah
you
could
install
it.
A
If
not,
it
was
a
common
and
it
should
all
be
included,
but
we
had
no
check
in
a
verification
of
that.
So
so
that
was
one
issue
that
came
up
also,
probably
an
ugly
side
effect
is
when
you
install
the
chart
each,
he
tried
to
deploy
it
and
failed.
So
people
come
back
and
say:
look:
why
did
this
try
to
install?
It
came
back
with
a
message
which
are
showing
a
while
around
I
think
no
objects
available
which
wasn't
very
explanatory
and
then
your
stock
would
it
deployed.
A
And
then,
when
you
uninstall,
it
actually
puts
put
it
quite
a
kind
of
a
side-effect
ugly
message
back
again.
So
all
in
all
it
was,
it
was
bit.
Untidy
wasn't
very
good
for
UX
and
also,
if
you
had
a
chart
with
seriously
definitions
in
it,
and
you
only
wanted
to
use
them
as
definitions
or,
for
example,
you'd.
An
application
chart
with
noise
definitions
in
it.
But
you
didn't
want
to
deploy
the
artifacts.
You
couldn't
do
that
either,
because
once
the
release
artifacts
are
in
the
chart,
they
would
get
deployed.
A
A
A
What
this
means,
then,
is
it
gives
you
it
gives
you
these
capabilities,
then
that
also,
if
you
have
an
application
chart
with
nice
definitions
in
it,
that
you
just
want
to
use.
But
you
don't
want
to
deploy,
you
can
set
its
type
to
library
and
then
basically
the
artifacts
won't
be
deployed,
and
this
is
the
same
with
dependencies
as
well
and
also
obviously
it's
staying
backwards
compatible.
A
Obviously
I
trying
have
to
put
something
out
in
a
hat.
But
for
the
moment
we'd
say
what
and
we'd
probably
have
a
talk
today
on
in.
Please
come
along
to
talk
today
about
the
hen
community
and
getting
involved
in
Helen
community
as
a
contributor
or
and
if
your
contributor
already
to
extend
an
act
later
on
in
the
day,
we
tailor
myself
because
we're
going
to
talk
about
this
and
some
of
the
tools
and
stuff
and
ways
to
get
going.
Okay,
so
scaffold
charts,
is
always
great
way
to
get
going
and
kicks
them.
To
note.
A
So
we're
going
to
do
forces
I'm,
going
to
show
you
what
the
templates
look
like,
if
you
haven't
seen
it
before
for
a
scaffold
chart,
so
the
scaffold
Sharpe
basically
is
a
simple
engine.
X
Server,
that's
deployed
and
it's
a
nice
way
to
test,
often
and
charts.
So
you
can
see
here.
This
is
yeah.
Okay.
We
can
see
here
that
it's
pretty
standard
you
can
see
here
that
the
image
here
it
includes
an
image
that
image
is
defined
as
as
an
engine
X
image
inside
and
their
values
file,
and
basically
it
just
deploys.
A
A
That
might
be
the
same,
have
the
same
type
of
code
that
you
have
in
the
manifest,
and
what
we
want
to
show
here
is
that
if
you
take
the
common
chart
and
the
base
chart-
and
you
define
your
own
common
charts,
how
you
can
simplify
your
knees.
So
what
I'm
going
to
do
is
rather
than
see
me
miserably
typing
in
front
of
you,
I'm
going
to
pull
across.
A
B
A
Okay,
now,
when
I
look
at
the
files
again,
you
can
see
now
in
this
situation.
What
I've
done
here
is
I've
included
the
template
from
the
common
from
the
common
chart.
Okay,
so
if
you
get
a
chance
quote
today,
the
incubator
repo
and
have
a
look
at
it,
so
I've
included
its
common
service
and
what
it
means
is
then
all
I
have
to
do
is
define
its
service
and
basically
I
pick
up
all
the
default
code
like
I
had
in
there
earlier
and
when
I
do
the
deployment
I.
A
Okay
and
again,
I
include
what
I
talked
about
the
key
that's
defined.
So
this
is
the
key
that's
defined
in
the
base
definition
template
for
common
dock
deployment.
There
is
the
key
and
that
that
I
included
here
by
calling
templates
or
you
can
also
call
it
include
as
well-
and
you
can
see
here
that
basically
I
pick
up
all
the
common
chord
and
then
all
that
I
change
here
as
I
decide
to
change
the
replica
set
and
use
the
value
of
my
own
replica
set
okay.
A
We
made
a
few
changes
around
the
charts
and
Andy,
and
that's
why
we
bumped
the
API
version.
So
one
of
these
things
remembers
what
I
mentioned
earlier:
the
type
field.
Okay,
you
can
see
it's
application
here
and
the
API
version
has
bumped
up
to
v2
one
other
thing
we
did
was
we
removed
a
no,
it's
still
backwards,
compatible
boo
in
from
V
tree
going
on.
We,
you
can
now
define
your
your
dependencies
inside
in
the
chart,
yeah
milfoil
and
we're
pretty
much
deprecated
in
the
requirements
file.
A
A
Okay,
so
what
we've
done
here
is
you've
seen
this
before
this
is
this?
Is
your
pendants,
your
include
in
here?
If
you
haven't
seen
it,
you
give
it
the
name
of
the
particular
chart
that
you
want
to
include
and
then
where
it's
coming
from
in
this
situation,
it's
coming
from
the
Henri
PO,
the
hellim,
repo
incubator,
repo
and
then
the
version
that
I
want
okay.
So
this
means
no
one
going
to
use
the
the
common
library
and
gonna
include
it
and
pick
up
the
capabilities
of
the
definitions,
then
as
well.
A
One
last
thing
I
have
to
do,
and
this
is
just
something
big
in
the
scaffolds
which
art
envy
tree.
We
just
changed
how
you
include
the
image,
so
it
now
uses
the
app
version
for
the
image
for
the
engine
X,
as
opposed
to
the
tag
for
before.
Unfortunately,
the
common
chart
is
only
it's
still
using
the
old
tag
and
I
haven't
got
around
to
change
it.
So
it's
something
we
probably
do
for
v3,
but
so
I
have
to
just
do
one
work
around
a
minute,
so
I
just
need
to
add
the
tag
here.
A
And
I,
instead
of
calling
it
stable
and
I
was
one
of
the
reasons
why
we
came
away
from
it
as
well
that
just
a
constant
is
stable,
wasn't
a
great
idea:
we've
gone
specific
under
type
on
and
so
I'm
going
to
use
one
16.0
and
that's
off
the
top
of
my
head.
So
if
it
doesn't
work,
obviously
we
should
have
used
stable
board
and
I
will
see
how
we
go
on
that
okay.
So
where
am
I
no
so
right
we
have
the
chart.
A
We
have
included
a
common
library,
we've
used
its
definitions
and
know
what
we're
going
to
do
is
we're
going
to
render
it
and
see.
Does
it
actually
work?
Okay,
and
if
it
works
great,
if
it
doesn't
we'll
just
say:
look
you
know
you
could
have
bought,
but
we're
going
to
go
with
that.
It
works.
Ok,
yeah!
You
do.
Please
clap
you.
A
We'll
go
dry
run,
so
if
you
haven't
used
dry
run
for
it's
a
nice
way,
it
doesn't
deploy
or
install
a
load
into
your
cluster
or
does
the
render
and
write
true.
So
you
can
tell
if
there's
any
errors
in
it
or
not?
Okay,
it's
a
nice
way
of
debugging,
okay.
So
all
right,
brilliant,
so
I've
included
the
dependency
but
I
forgot
to
to
update
the
dependency.
A
A
C
A
A
Okay,
so
you
can
see
here
that
the
service
manifest
has
been
rendered
out,
so
it's
picked
up
all
the
definitions
that
were
inside
in
the
the
common
service
file
and
and
then
when
we
go
to
the
deployment,
the
same
thing
has
happened
as
well,
so
you
can
see
here
that
it's
pulling
this
capability
and
a
whole
lot.
So
this
capability,
as
you
know,
is
already
in
v2,
so
you
can
use
it
away.
A
B
A
Yay,
so
there's
your
landing
page
for
engine
X,
so
that
just
shows
we've
deployed
it
or
whatever.
So
what
we
want
to
have
a
quick
look
at
now
is
around
the
common
chart.
So
what
I
did
was
I
pull
down
the
common
chart,
the
way
to
go
and
extracted
it
out
and
what
I'm
going
to
do
is
I'm
gonna
show
you
when
you
try
to
install
it
at
the
moment,
what
happens?
Okay
so
and
just
make
sure
that
we
have
we
ever
demoed
area?
Okay.
A
So
what
I'm
gonna
do
is
I'm
gonna,
install
comma,
no
you'll
notice
to
inhale
tree?
You
don't
need
to
use
name
anymore.
You
can
just
give
us
helm,
install
the
name.
We're
aware
of
your
chart
is
okay,
also
on
top
of
that
as
well,
and
you
have
to
specify
your
name
or
specify
generate
name,
so
it
doesn't
generate
a
name
on
the
fly
anymore
and
the
reasons
for
the
change
in
this
is
for
standardization,
with
the
the
other
cue
commands,
basically
so
yeah.
A
So
if
you
see
that-
and
you
come
up
with
something
go,
why
doesn't
that
work
anymore?
There
you
go
probably
mostly
in
production
anyway,
when
you're
in
production
you're,
now
really
gonna
give
it
at
hoc
names
like
whatever
it
was
funny
cat
or
whatever
the
different
ones,
where
I
can't
remember,
there's
some
good
ones,
stuff.
Okay,
all
right.
B
A
As
you
can
see,
this
isn't
fabricated.
Obviously,
because
you
know,
if
you
really
had
this
down
to
tea,
you
wouldn't
be
making
these
little
mistakes.
So
there
we
go
all
right.
So
when
you
try
to
install
it,
you
get.
This
lovely
met,
oh
shoot
here
we
go.
This
is
what
happens
when
you
go
test
in
the
night
before
I
have
to
reverse
everyone
cause
Roy.
Is
there
for
a
minute.
B
A
A
A
You
can
see
here
that
an
its
definition
and
that,
basically,
it's
defined
defined
in
the
deployment
it's
also
including
another
ID
here
coming
up
metadata,
such
as
metadata
file
out
there
that
defines
the
different
metadata,
the
labels
and
the
name
etc
like
that
and
even
foiled
in
goes
into
an
order
foil
for
the
specific
name
and
like
you'd
have
on
in
under
helpers.
You
know,
looking
at
the
link
to
the
foil,
full
name
or
whatever,
like
that.
A
You
also
see
here
that
you
have
yeah
come
in,
am
down
here
for
the
name
in
and
then
you
also
have
a
container
or
no
I'm
not
going
to
go
into
all
of
them.
Please
have
a
look
at
yourself,
but
you
get
the
idea
that
the
definitions
are
and
there's
a
lot
of
mod
realization
here
and
including
basic
give
the
different
definitions.
Okay,
so
let's
jump.
A
Okay,
so
hands
up
here.
Who
knows
what
that
message
means
besides
Matt
Fisher,
obviously
at
the
back
yeah
I
swear.
If,
if
you
know
what
I
mean,
if
you
disloyal
after
a
nice
weekend,
you
would
not
know
what
what's
going
on
there.
So
that's
that
I
call
that
the
message
of
debt
really
sometimes
you
know
cuz
people
come
back
here.
What's
that,
do
you
know
what
it's
crying
when
you
know
what
it
is?
But
when
you
don't
know
what
it
is
its
job,
it's
not
friendly!
Okay,
also
what
it
was
lovely
for.
You.
A
Yeah,
it
deployed
it.
No
sorry
failed
there
we
go
all
right
now,
very
useful,
so,
let's
take
it
out.
Okay,
so
in
in
helm
tree
the
helm,
delete
command
has
now
become
hello,
moans
uninstall,
and
what
I
like
about
it
is
is,
and
madness
is.
It
also
removes
everything,
so
it
doesn't
leave
the
metadata
hanging
around
everything
goes
by
default.
There
is
a
flag
in
there
for
the
people
who
loved
hanging
around
for
you
to
hang
on
to
it.
If
you
want
okay,
but
by
default
it
goes
out.
A
A
A
Right
so
I
think
that's
a
lot
better,
but
it
loads
sixteen
going
forward
as
well,
because
we
know
have
basically
a
type
or
an
object
or
concept
of
what
our
charts
are
if
their
application
are
common
or
if
someone
comes
up
with
a
an
order.
Type
again,
don't
draw
it
because
everyone
has
great
imaginations
out
there,
so
we're
going
to
find
an
order
type
at
some
say
it
so
yeah,
please
go
with
it.
So
right,
let's
jump
back
to
finish
off
because
we're
nearly
there
are.
We.
A
Okay,
right
to
summarize,
the
main
thing
here
is:
what
we
want
to
do
is
because
we
see
the
value
of
library,
charts
and
even
daughter
started
orders
an
initial
I
suppose
concept
from
from
a
poacher
and
putting
it
out
there
and
saying
right.
This
is
a
nice
wait
where
you
can
basically
defining
things
and
reuse
afterwards
and
basically
respect
the
droid
principle,
and
we
saw
that
in
helm
too.
A
A
You
can
have
library
or
you
can
have
application
by
default,
its
application,
and
also
to
that,
your
your
common
charts
are
includable
and
all
installable
and
that
you
use
them
like
you
want
to
use
any
type
of
chart
pie
in
order
chart
you
you,
you
include
it
in
its
dependency,
so
so
that's
all
from
me
tanks.
So
you
can
contact
me
there.
A
If
you
have
any
questions
around,
we
still
have
time
for
questions
is
the
5/2
or
okay,
so
just
reach
out
to
me
come
up
and
talk
to
me
I'll
be
around,
and
if
you
have
any
questions
like
I've
shown
a
few
things
around
helm
tree
in
this
as
well.
So
if
any
questions
around
home
tree
come
around
and
talk
to
any
of
us
and
yeah,
thank
you.
