MetaCall Builder

Advanced builder based on Buildkit for selectively build compact Docker images selecting the only required languages.

go build main.go

Run

Run with buildctl-daemonless

Requirements:

• BuildKit

MacOs :

For MacOs, you can use install buildkit using brew and lima for rootless containers, and run the script after the installation.

$ brew install buildkit
$ brew install lima

./main py node rb | ./hack/buildctl.sh build --output type=docker,name=imagename | docker load

Useful Tools

Dive can be used to analyze each layer of the generated image

dive <your-image-tag>

This opens up a window where in we can see changes in each layer of the image according to preferences.

Ctrl + L : To show only layer changes

Tab : To switch view from layers to current layer contents
