Base definition migration guide (December 2025)
The base configuration syntax using os and tag is deprecated.
Deprecated configuration
Previously, the base layer was configured using an os along with a tag, like this:
base:
os: ubuntu 24.04
tag: 1.2
New configuration
Now, the base layer is configured using an image along with a config.
base:
image: ubuntu:24.04
config: rwx/base 1.1.1
The image property references a container image, so it now contains a colon
where the previous value for os contained a space.
