How do I install packages?

As the title says. What's the recommended way to get this running for projects more complex than a single file? Should I install stack? Use the pre-installed nix? What's the expected workflow?

Looks like stack on Alpine Linux is not that simple commercialhaskell/stack#2387

At least cabal can be installed using sudo apk add cabal . I now simply run cabal run in a docker termina. I haven't used that setup yet to develop projects with complicated builds, I can't comment on how good this idea is...

seems like stack for Alpine linux is available now?
https://hub.docker.com/r/fpco/alpine-haskell-stack/tags

I'm not sure if it's possible to build both hie and alpine-haskell-stack into one image, afaik Docker doesn't allow multiple FROM in one Dockerfile (second image will overwrite first)?

Is it easy enough to combine them?

Also tried to install stack inside image manually in VS Code terminal:

curl -sSL https://get.haskellstack.org/ | sh
export PATH=$PATH:/usr/local/bin

it installs just fine however any stack commands give the same error

"no setup information found for ghc-8.6.5 on your platform.
This probably means a GHC bindist has not yet been added for OS key 'linux64-ncurses6'.
Supported versions: ghc-7.10.3, ghc-8.0.1, ghc-8.0.2, ghc-8.2.1, ghc-8.2.2"

GHC 8.6.5 is definitely installed though : ghc --version gives
The Glorious Glasgow Haskell Compilation System, version 8.6.5

I guess the root cause is in the base image?

I got the same issue
