Hi!
I’m trying to deploy a project to fly.io, and for that I need to create a docker file. However, it seems to fail on phx.digest. The project can be found at: monorepo/solo_leveling_go at master · JulianBuse/monorepo · GitHub
The Dockerfile:
# Find eligible builder and runner images on Docker Hub. We use Ubuntu/Debian instead of
# Alpine to avoid DNS resolution issues in production.
#
# https://hub.docker.com/r/hexpm/elixir/tags?page=1&name=ubuntu
# https://hub.docker.com/_/ubuntu?tab=tags
#
#
# This file is based on these images:
#
# - https://hub.docker.com/r/hexpm/elixir/tags - for the build image
# - https://hub.docker.com/_/debian?tab=tags&page=1&name=bullseye-20210902-slim - for the release image
# - https://pkgs.org/ - resource for finding needed packages
# - Ex: hexpm/elixir:1.12.3-erlang-24.1.4-debian-bullseye-20210902-slim
#
