Haggai Philip Zagury
My Solution driven approach is
based on hands-on and deep
understanding of Operating
Systems, applications stacks
software languages and
frameworks, Networking, Cloud
and Cloud Native solutions.
Open thinking and open
techniques ideology - driven by
Open Source technologies

3.
Tend to take our
roadmap / work
pretty seriously
(i hope 😉)

DevEx | N🚫 place like 🏠 k3s
k8s.local with cloud-native tooling

5.
DevEx
A Cloud-Native
Another touchpoint
In our
Development Journey

6.
What does that mean for developers ?
What is Cloud-Native thinking?

7.
Developer Journey
● Define the workload “gestimation”
● Define the sw language

8.
Developer Journey
● Define the workload
● Define the scale
● Define the architecture
● Define the sw language
● The cloud will take care of the rest …
● We will declaratively tell it how

9.
Developer Self-Service
Cloud Native | like ordering on amazon …

10.
Self-Service Cloud Resources
cpu, ram, [ disk, network ]

11.
Self-Service Kubernetes Resources
cpu, ram, [ disk, network ]

12.
Use the Best Arch to get the job done
What is it ?

13.
🏠 ? 127.0.0.1 ?
A Cloud-native desktop :)

● Develop Operations is by design
● Treat your laptop as the 1st cloud
○ Run your code inside a container
○ Run your container inside a pod
○ Portable & Scalable application

● Sounds 2 good 2B true …

The laptop it A Cloud, kubernetes is the
Generic API
- K3D is a cloud provider ! …
- ContainerD is the “image provider”
- Kubectl / Kubernetes API / SDK is
your cloud native interface ….

16.
Kubernetes built for dev’s
K3d vs k3s vs Kind vs Microk8s vs Minikube
● They all have their advantages / disadvantages
● They all provide an “all-in-one” kubernetes distro

17.
K3S
● Lightweight certified Kubernetes distro
● 40MB binary, 512MB memory consumption
● Single process integrated Kubernetes master,
Kubelet, and containerd
● SQLite in addition to etcd
● Simultaneously released for x86_64, ARM64,
and ARMv7

18.
K3D
● hot-reloading of code
● Full cluster lifecycle
○ create nodes (servers|agents)
○ single / multi-server clusters
● You can test scaling up / down (HPA /
Other)
● Integrated LoadBlancer Container
Development booster

● hot-reloading of code
● full cluster lifecycle
○ create nodes (servers|agents)
○ single / multi-server clusters
● You can test scaling up / down (HPA / Other)
● Integrated LoadBlancer Container
● Run a local container registry
Like A managed service

Local registry (mirror)

○ create nodes (servers|agents)
○ single / multi-server clusters
● You can test scaling up / down (HPA / Other)

● Run a local container registry
mirrors:
docker.io:
endpoint:
- "http://mycustomreg.com:5000"
configs:
"mycustomreg:5000":
auth:
username: xxxxxx # this is the registry username
password: xxxxxx # this is the registry password

PUT IMAGE HERE
AND CROP AS CIRCLE
127.0.0.1 | Logging workloads
tail -f “cluster-logs”
- Log standard kubernetes workload definition
- Automatically categorize workload based on
our labels
P.S you can run both locally log like in prod

28.
PUT IMAGE HERE
AND CROP AS CIRCLE
127.0.0.1 | Monitoring workloads
Modern monitoring
- Metrics, metrics, metrics - standard kubernetes
workload definition
- Automatically analyze workload based on our labels
P.S you can run both locally monitor like in prod

29.
PUT IMAGE HERE
AND CROP AS CIRCLE
127.0.0.1 | Scaling workloads
Event Driven (Reactive) Architecture
- Utilize standard kubernetes workload
definition
P.S you can run both locally
- App
- Queue
BTW: & this is also OLD NEWS ;) …

30.
PUT IMAGE HERE
AND CROP AS CIRCLE
127.0.0.1 | GitOps
git -repo - app-sync
- Changes are scm based
- Automatically categorize workload based on
our labels
P.S you can run both locally deploy like in prod

Reduce Frustration | Micro Feedback loops ++
● Helper-tools / Utilities
● Make (my personal favorite)
● Kubectx / kubens
● Common functions
○ Set cloud provider project / profile
○ Get a secret from credentials store
● IDE -plugins
● IDE - the obvious
○ Auto lint / build / deploy

32.
Shorter ! Feedback Loops
DOD - Definition of Done
- How do I know it’s done ?
- How does the team know it’s done ?
- How does management know it’s done ?
- How does NOC know it’s functional ?

33.
Adopt Capabilities & Best Practices
DRY principles
- Challenge the controller pattern
- Custom types - standard api
- Cloud Native workflows
- Opinionated workflows

34.
Operator Pattern
- Frameworks
- Reusable Architecture
styles
- GitOps
- FaaS
- ArgoCD
- …
- Data pipelines
- Streaming

35.
Crossplane
- A native way of provisioning cloud
resources
- Think of a helm chart which can create
an managed database (e.g. RDS) from
snapshot …
