CI/CD today
…aka the pain we all know
Day 1…
…how it starts 😃
Day 101…
…760 lines of YAML & Bash 😟
# Foobar pipeline
# Include the Common CI pipeline parameters.
include:

#- /force-app/ui-tests/pipeline.yml
stages:
- build-metadata-package
- run-js-tests

We are still dealing with drift in 2025?!
All is well until you need to make changes
- Upgrades (eg. new version of Go)
- New tooling (eg. new security scanner)
- Moving to a new platform
Lessons learned
YAML…
- is not reusable 1
- is not composable
- provides poor flow control
- is not portable
YAML is a poor choice of “language” for software development workflows.
CI/CD is just an interface
- Developer and CI environments overlap
- Drift between them is annoying
- Time wasted due to “push and pray”
- CI/CD is no longer a dev or platform only domain
Dev + CI = Software development workflows
No more YAML
- Use a general-purpose programming language
- One that developers/platform engineers already know
- Reusable components
Workflows that run anywhere
- Run CI locally
- No more push and pray
- No more drift between dev and CI
- Bridge between developers and platform engineers
Workshop
Let’s get our hands dirty!
Workshop environment
- Use your own machine
- Use the online playground
Prerequisites
- Make sure Docker is installed and running.
- Make sure Go is installed.
- Install the latest Dagger CLI.
- Make sure you have a GitHub account set up with SSH keys.
- Last, but not least: you’ll need your favorite text editor or IDE.
