Grafana-sourcemap-less

This is a simple tool to generate Grafana docker images without sourcemap.

Take 8.5.27 as an example, which will reduce the image size by 42MB. (from 248MB to 206MB)

Inspired by rules_oci (using bash, crane and yq).

Usage

Because it is not clear how many people need sourcemap-less images, there is no automation to push the processed images to dockerhub (which may occupy a large public space), so you can make them yourself.

If it helps you, you can star this repo, so I will know how many people need this mirror image.

prepare toolchain (crane and yq)

curl -fl https://github.com/mikefarah/yq/releases/latest/download/yq_linux_amd64 -o /usr/local/bin/yq && chmod +x /usr/local/bin/yq
curl -fL https://github.com/google/go-containerregistry/releases/latest/download/go-containerregistry_Linux_x86_64.tar.gz | tar -C /usr/local/bin -xzf - crane

get this script

wget https://raw.githubusercontent.com/hunshcn/grafana-sourcemap-less/master/handle.sh

pull image

crane pull --format=oci "grafana/grafana:8.5.27" "./image"

run script

bash handle.sh ./image

push image

crane push ./image "yourregistry.com/grafana/grafana:8.5.27-sourcemap-less"
