nanolayer helps keep container layers as small as possible.
It does so by automatically deleting any installation leftovers (such as apt-get update lists, ppas, etc)
pipx install nanolayer
Usage:
nanolayer install gh-release cli/cli gh FROM python:3.10
RUN apt-get -y update && apt-get install -y htop layer size: 22MB
FROM python:3.10
RUN curl -sfL https://github.com/devcontainers-contrib/nanolayer/releases/download/v0.4.0/nanolayer-x86_64-unknown-linux-gnu.tgz | tar fxvz - -C / && \
chmod 755 /tmp/nanolayer && ls /tmp && \
/nanolayer install apt-get htop && \
rm /nanolayerLayer size: 1.6MB
