Yesod fails to run on docker

I'm trying to build yesod according to the docs on docker:

# Dockerfile
FROM ubuntu:22.04
RUN apt-get update
RUN apt-get install curl -y
RUN curl -sSL https://get.haskellstack.org/ | sh
RUN stack new my-project yesodweb/sqlite
RUN cd my-project && stack install yesod-bin --install-ghc
RUN cd my-project && stack build

I get until the next to last step, but then fail:

> docker build --tag host_yesod --file Dockerfile .
 => [1/7] FROM docker.io/library/ubuntu:22.04@sha256:6042500cf4b44b  0.0s

 => CACHED [6/7] RUN cd my-project && stack install yesod-bin --install-ghc
 => ERROR [7/7] RUN cd my-project && stack build 100.7s

Here is the error message:

100.6 Error: [S-7282]

100.6        While executing the build plan, Stack encountered the error:

Any ideas how can I fix this?

Solution

  • The line you're looking for is

    92.67 language-javascript
  > happy: src/Language/JavaScript/Parser/Grammar7.y:
  hGetContents: invalid argument (invalid byte sequence)

    Googling "docker" hGetContents: invalid argument (invalid byte sequence) tells us that this means the source code file is not UTF-8 and leads to this StackOverflow answer. So try appending the line en_US.UTF-8 UTF-8 to the /etc/locale.gen file in your docker image.
