K8s! K8s!

Why are we here? - Show a solutions-based way to code, build and ship applications - New tools are constantly introduced, it is hard to judge the impact on developers teams - Teams suffer from slow feedback loop cycles due fragmentation in tools ecosystem and complex environments - It is hard to create consistent experiences when glueing tools that were conceived with different use cases in mind

Core idea Remember how it felt when you were able to have a good understanding of the system mostly by mostly checking at the code

Marcos Lilljedahl (@marcosnils) Software engineer @Dagger Mauricio Salatino (@salaboy) Software engineer @Diagrid @Knative @Dapr @Keptn - Distributed systems - Developer tools - Platform engineering (before it was cool) - OSS maintainer & contributor

Let’s look at this “simple" system Forked from : https://github.com/dockersamples/example-voting-app 41 Yaml # File changes 2019 - 2024: 40 Yaml 30 CS 17 Dockerfile

- Containers, configurations and Environments - Services are tied to the provided infrastructure - Different delivery pipeline and practices with very little reuse, small difference can cause slowdowns and issues Challenges

Let’s zoom in a bit more

How could we improve this?

Databases KV Stores Message Brokers Secret Stores A unified programming model exposing application-level APIs for building distributed apps using best practice software patterns and practices with complete code portability across cloud and edge. Distributed Application Runtime

Dapr Building Blocks

Dagger is CI as code (and much more)! Transform your messy scripts into code pipelines that run the same way locally and in CI

Dagger ● Your team's "designated devops person", hoping to replace a pile of artisanal scripts with something more powerful. ● A platform engineer writing custom tooling, with the goal of unifying application delivery across organizational silos. ● A cloud-native developer advocate or solutions engineer, looking to demonstrate a complex integration on short notice.

27 Dagger API https://docs.dagger.io/api/reference/ ● Container ● Directory ● File ● Secret ● Service ● Socket

Dagger + Dapr

Dagger Module for Dapr (Ecosystem) - Anyone can now create consistent experiences to work across environments for teams to leverage tools like Dapr or any other - We can rely on an a vibrant ecosystem of integrations to build API based solutions independently of the underlying language

Bringing the experience closer to developers

Takeaways - Hide complexity behind APIs - Build beautiful experiences for your teams - Always aim to reduce your teams’ cognitive load
