How can I overcome Nokogiri dependency when dockerizing Ruby on Rails APi - ruby-on-rails

Question

I've been working on dockerizing a simple Ruby on Rails API with a SQL database, and I've been encountering the following error:
ERROR: It looks like you're trying to use Nokogiri as a precompiled native gem on a system with glibc < 2.17:
/lib/aarch64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /usr/local/bundle/gems/nokogiri-1.13.3-aarch64-linux/lib/nokogiri/3.0/nokogiri.so) - /usr/local/bundle/gems/nokogiri-1.13.3-aarch64-linux/lib/nokogiri/3.0/nokogiri.so
If that's the case, then please install Nokogiri via the `ruby` platform gem: gem install nokogiri --platform=ruby or: bundle config set force_ruby_platform true
Please visit https://nokogiri.org/tutorials/installing_nokogiri.html for more help.
Here's my dockerfile
FROM ruby:3.0.0
RUN apt-get update && apt-get install -y build-essential
RUN apt-get install default-mysql-client -y
RUN mkdir /task
WORKDIR /task
ADD Gemfile /task/Gemfile
ADD Gemfile.lock /task/Gemfile.lock
RUN bundle install
ADD . /task
And here's my compose file

Note that I am working on a M1 Macbook Machine
I am still new to Ruby so it might be a stupid issue that's causing all this hassle

Answer 1

Looks like this is indeed caused by the fact that you are on an ARM platform (Mac M1 being ARM processors).
This is also somehow shown by that path in your error message:
/usr/local/bundle/gems/nokogiri-1.13.3-aarch64-linux/lib/nokogiri/3.0/nokogiri.so
aarch64 being another name of the ARM 64 bits architecture.
In order to overcome this, you will have to use the same trick you used for your MySQL container: swap it to a linux/x86_64 platform.
So, in your docker-compose.yml, you should have:
## the file above this stays the same
app:
platform: linux/x86_64
## the file below this stays the same
And adapt your Gemfile.lock, the line
nokogiri (1.13.3-arm64-darwin)
Should become
nokogiri (1.13.3-x86_64-linux)
Then, at least rebuild that container:
docker compose down
docker compose up --build
