Horacio Gonzalez with DevOpsSpeakeasy at DevoxxMA 2022

hello everyone here we are at the devops

Speakeasy at devops Morocco and Melissa

McKay I work with jfrog as a developer

Advocate and I’m here with Horatio

Gonzalez today hello would you like to

introduce yourself let the audience know

who you are yeah

living in France so sorry about my

accent it combines the worst traits of

the Spanish and French accent

I am director of different developer

relations at obvious cloud and European

cloud provider

awesome well how was your experience

here so far we’re on day two of the

conference great absolutely great it’s a

wonderful confidence and I am really

happy to be here is this your first time

yeah it’s my first my first one awesome

same same with me this is my first time

in in this continent and at devops

Morocco it’s been a fantastic experience

I really like it a lot so I was looking

at the schedule earlier and I saw you

actually had a workshop on the very

first day yeah tell us a little bit more

about it what was it called it was about

kubernetes operators with Java okay cool

your Java programmer then yeah

since the last century so for me being

able to create things for kubernetes

with Java is very exciting because three

years ago I four years ago I got

interested in kubernetes I began to load

to do a lot of things but the main

language was to always go

and now I have done a lot of talks about

kubernetes and all that but it is the

first time I can do a talk about

kubernetes with Java combining the two

things and it was really nice well

you’re after my heart too because I am a

Java developer as well and

um rarely do I meet a Java developer

today that that’s all we’re doing right

we have our hands in many different

things and doing all these different

things and as a developer we need to

start adding these things to our toolbox

so in your Workshop you were talking

about kubernetes operator specifically

right can you explain to our audience

what what is that what’s an operator

well kubernetes is very interesting for

for developers

because it’s they kubernetes allows

developers to determine to deploy

microservices architectures in an easy

way and to keep doing monitoried and to

be sure that everything is working as it

should so kubernetes is wonderful but

but when you are trying to deploy a lot

of different applications in the in a

kubernetes cluster things can get messy

because you are doing a lot of manual

work

the idea is if you are deploying tens of

microservices application it’s one with

tons of containers in a cluster you will

have to need a system to be there doing

lots of manual day-to-day tasks tasks

that haven’t agreed added value for this

is admin

so as kubernetes philosophy is about

automation the idea of kubernetes

operator is to try to automate the

day-to-day job of the acetamine

instead of having the system hey I’m

going to deploy an application so I need

to deploy 10 ports and deployment

service and some someone summons some

you are going to use the operator a

operator deploy a

Kafka cluster and it will do everything

but not only that it will help you in

all the life cycle of the application uh

doing upgrades rollbacks getting metrics

or even if the operator is if the

equivalent operator is a bit smarter

even things like hey you’re looking at

the space consummation in 10 days you

won’t have any more disk space so I am

going to get a new persistent volume for

you so all those tasks that for a human

operator they are easy but they are

complex because a lot of manual themes

they get automated and the system can

get more time for doing more added value

tasks

we aren’t replacing the human operator

we are we are adding a kubernetes

operator to take care of the useless

day-to-day task and allowing the human

operator to do more interesting things

that makes sense that makes a lot of

sense this is something that I’ve

struggled with early as a you know

developer getting involved in devops in

general I start you know learning more

about deployments and how that actually

works and there’s a lot of work involved

but there’s a lot that can be automated

too so that makes a big difference

um what do you think every now and then

I get some pushback from Developers

that you know deployment and that kind

of stuff is out of our purview we don’t

want to work with that don’t want to do

that what do you what’s your opinion on

that matter well uh I I consider myself

a developer because I’ve begun as a

developer and I have done a lot of java

a lot of front-end development but for

me

it is really interesting for a developer

to have one foot on the system area to

be a bit of a devops

I am never going to be a real Italian

but if you know enough to understand

more or less how things are done you

will be able to do things in a better

way and you will be able to communicate

better with the operations teams and for

me the in an Ideal World developers

should know a bit the basics about

operation deployment and all that and

operations people should know a bit

about the development it makes

communication easier and for me the real

problem it is in a technical one the big

most difficult problems are always

relational one if you understand the

work of your co-worker and they

understand yours Communications will be

far easier for me yeah I 100 agree with

you I’m so happy you had that answer we

I don’t have anything left to say just

agree with you completely

um I I know there’s some

misunderstanding sometime about devops

in general that um you know developers

don’t need to know anything about

operations but just think about how

microservices came about right I mean

the whole purpose of microservices is to

affect deployment to be able to scale

differently right and if a developer

understands

how things are being deployed then it

might make some big differences on how

you design the software to begin with so

it makes a lot of sense for us to know

this have like you said have one foot in

that group

and be able to know a little bit yeah it

really helps it isn’t enough but because

sometimes the problems are

organizational if you have a developers

teams on one side in One Direction an

operations team in other side of the

company there is an organizational wall

between them that make communication

complicated so you must work on the

culture and the idea of knowing better

what the others do and you must also

work on

breaking down that wall in making people

work together and for me that’s a kind

of problem that is really wow wonderful

to

to deal with but it’s not a technical

one it’s a relational cultural

organizational one exactly and it’s all

about communication improving that

communication among the team yes now it

can be pretty overwhelming especially

for someone you know right out of school

as a developer to say okay now learn

kubernetes

but I mean the tools are getting better

so that it’s a little bit easier for us

to work with right

and if you are a developer a junior

developer you don’t need to know

everything about kubernetes you need to

understand the basis because if you

understand the basis of kubernetes you

understand how you must develop in order

to get things to work easy with

kubernetes you don’t need to understand

the low depends and the basis of

kubernetes

the conceptual bases are in complex so

you need to know a bit about containers

that okay you need to know what the

difference of phone number container to

a virtual machine and some details you

need to know

why kubernetes is useful to automate all

these containers

and you need to know how do you write

and manifest for your application it can

be done in one or two weeks

you don’t need to be a kubernetes master

I am I have been working with kubernetes

for five years and I am not a kubernetes

master at all you only need to know

enough to better work with it and for me

it shouldn’t be something it made you

afraid it uh it’s an opportunity to

begin to get that food on the operation

side I we talk about yeah so being in

devops doesn’t mean that you need to be

an expert in all the things I know you

can still be you know maintain your

expertise in development but just you

know be aware of what’s going on in the

operation side so you can communicate

sounds good today if you are a junior

been an expert in everything it’s not

possible but it’s not even a good thing

I prefer to be a generalist always

trained to learn new things and being

able to make relations between things

you can you learn today since you have

learned some time ago it is a travel to

be a developer you are always learning

and you have always lots and lots of

things you don’t know

you don’t if you are a junior you don’t

need to be an expert you don’t need you

need to keep learning and that’s enough

for me yeah same that’s what I love

about this industry too there’s always

something new to learn and even here at

devox Morocco you know I’ve been a

developer for over 20 years now and even

I’m learning brand new things yeah

there’s always new things coming out new

tools so this is never something that

you will finish and be done learning

you’re always going to be coming up with

with new things to learn

well it’s been amazing conversation with

you I’m so glad to have met you here in

devox Morocco

um yes I I missed your Workshop are you

going to be giving one again in the

future I have submitted it to several

call for papers so I hope I will give

you I am giving it with my colleague

Stefan I hope we will we will be giving

it another conferences and we are trying

to record it in a good format to put it

in YouTube awesome I’ll be looking for

that I’ll be looking for your name in

other conferences too are there any

other resources you’d like to share with

our audience if if someone’s interested

in learning kubernetes starting at the

beginning

a real good resources a book written by

my friend orelibash understanding

kubernetes in a visual way

it’s a big book about kubernetes but a

very different book because it is all

the sketch notes already has done when

he was learning kubernetes you have

everything from the beginning to really

deep matters but in an easy way a lot of

drawings a lot of advice and it is

really fun to read so for me right now

it is the better resources for somebody

looking to learn kubernetes awesome all

right well there you have it here we are

at devops Morocco with Horatio Gonzalez

thank you very much thank you very much
