Building container images
You can use Dagger to build container images. Here's a simple example of a Dockerfile build:
Building with CUE
Dockerfile files are easy to start, but you can also build images entirely in CUE. The following example produces the same image as above:
Automation
Building images in CUE gives you greater flexibility. For example, you can automate building multiple versions of an image, and deploy, all in Dagger:
Now you can deploy all versions:
dagger do versions
Or just build a specific version, without pushing:
dagger do versions 8.0 build
Multi-stage build
Another common pattern is multi-stage builds. This allows you to have heavier build images during the build process, and copy the built artifacts into a cleaner and lighter image to run in production.
