how to install on M1 (running in a container) #104

wdiechmann · 2021-12-20T21:04:58Z

Let me start by apologizing for 'fuming in the wrong kitchen' (this is not tailwindcss-rails per se - I actually anticipate it doing exactly what it should! It's much more likely some Docker container "thing" that lures the container into reporting "aarch64-linux" which I -- by now -- have learned repeatedly, is not a supported architecture by tailwindcss-rails !

Reckoning me not being alone on this crusade I risk the barrage and go forth:

Question: Does anyone know how to get Rails 7.0.0 to install with TailwindCSS in containers on the Apple M1 ?

the sordid details

Apple's latest/finest 'sand' - the M1 - is screaming fast but somewhat of a challenge to run Docker containers on;

Like with the sparkling fresh Rails 7.0.0 when doing rails new . --css=tailwind

I have a Dockerfile like this

[ update: 2021-12-20 22:30 CEST: the from image is actually arm64v8/ruby ]

FROM arm64v8/ruby:3.03
#
# I took great inspiration in this work by [Will Schenk](https://willschenk.com/articles/2020/rails_in_docker/)
#

WORKDIR /app

COPY src/Gemfile /app/Gemfile
COPY src/Gemfile.lock /app/Gemfile.lock
RUN gem install bundler && bundle install


# Add a script to be executed every time the container starts.
COPY entrypoint.sh /usr/bin/
RUN chmod +x /usr/bin/entrypoint.sh
ENTRYPOINT ["entrypoint.sh"]
EXPOSE 3000

# Configure the main process to run when running the image
CMD ["rails","server","-b","0.0.0.0"]

and a docker-compose.yml like this (the db part is merely for completeness - it serves no purpose in this trickery

#
# Most if not all of it is a blatant c/p from
# Will Schenk's https://willschenk.com/articles/2020/rails_in_docker/

    depends_on:

When I let it 'rip' -- hoping to install tailwindcss goodness after the fact (it failed during the initial rails new too ) -- I get this sad reply:

√ mindling % x rails tailwindcss:install

Please install tailwindcss following instructions at https://tailwindcss.com/docs/installation

but for some reason the container keeps 'bragging about being' aarch64-linux 😆

So - now my heading (and my bearing for that matter too) is somewhat lost!

How do I get my containers to swallow their (linux) pride and start behaving?

@wdiechmann - Sorry you're having a problem, I'll try to help.

Inside your docker container, what does ruby -v emit? What does gem env emit?

wdiechmann · 2021-12-20T21:25:17Z

oh no - don't be sorry - it's me being sorry not able to offer any help solving this (giving back just something to the community) - but I'll take that help any given (Monday) 🤣

I guess I'm on my way to "the land of containers" -- pulling the finer print on the container underlines that tailwindcss-rails is entirely without fault (I think)

flavorjones · 2021-12-20T21:43:02Z

@wdiechmann OK, since your version of Ruby says it's aarch64-linux that's why it's trying to not installing x86_64-linux platform gems.

Your best bet is to follow the instructions at https://tailwindcss.com/docs/installation to install tailwindcss via npm.

wdiechmann · 2021-12-20T21:52:25Z

well - roger that - but I'm not going down the npm gauntlet again 🤣

not with this beautiful piece of 'ware letting out sirene songs from those cliffs up high 😄

but thx a bunch for holding my hand and administering a cold handkerchief on my forehead ❤️

wdiechmann · 2021-12-20T21:54:34Z

BTW - this docker/for-linux#1170 confirms it and now I just have to find out how to impersonate the correct platform for tailwindcss to ask for

it certainly is xmas all around 😌

wdiechmann · 2021-12-20T22:17:30Z

I'm addressing the issue here - placing all my faith in the "Gods of Container Heaven"

flavorjones · 2021-12-21T19:16:26Z

I think we can close this @dhh

wdiechmann · 2021-12-21T20:53:18Z

For good measure:

SOLVED!

build the container "by hand" - using docker build --platform linux/x86_64 and then stick the same platform argument into the docker-compose.yml (I suspect once there is an image you don't need to build it by hand anymore - how all the finer print reads is sadly beyond me) making the [important parts of the ] docker-compose.yml look like this:

#
# Most if not all of it is a blatant c/p from

paulodeon · 2022-09-05T18:58:55Z

I ran into the same problem and the above didnt work for me (perhaps I didnt follow all the steps)

Specifically I get the error ERROR: tailwindcss-rails does not support the aarch64-linux platform on M1 Mac running tailwind in an alpine docker container using the rails command bin/rails tailwindcss:watch

Digging into this gems code we can see it compares the platform with the matching executable

irb(main):001:0> Gem::Platform.match('aarch64-linux')
=> false
irb(main):002:0> Gem.platforms
=> ["ruby", #<Gem::Platform:0x0000ffff94611888 @cpu="aarch64", @os="linux", @version="musl">]

It seems that the musl causes a mismatch - this is the alpine stdlib and there is a ticket here which purports to fix it but does not: rubygems/rubygems#5852

My fix was to bypass the rails command and run the executable directly using something like this:

/usr/local/bundle/gems/tailwindcss-rails-2.0.12-aarch64-linux/exe/aarch64-linux/tailwindcss -i /app/app/assets/stylesheets/application.tailwind.css -o /app/app/assets/builds/tailwind.css -c /app/config/tailwind.config.js --minify -w

unikitty37 · 2022-11-21T16:51:25Z

I still can't get it working, and I'm very confused by the above. If my architecture is ARM, why do I want to force it to install x86_64 binaries?

Won't that end up running everything more slowly, under Rosetta 2 (and breaking completely when Apple discontinues that)?

flavorjones · 2022-11-21T17:10:40Z

Please make sure you're on the most recent version of Bundler. If you're still having problems, please open a new issue and we can dig in together.
