Laravel sail using yarn

Currently laravel sail only supports npm command on the docs.

I already publish the Dockerfile php artisan sail:publish.

And then customize the Dockerfile as follows

FROM ubuntu:20.04

LABEL maintainer="Taylor Otwell"

ARG WWWGROUP

WORKDIR /var/www/html

ENV DEBIAN_FRONTEND noninteractive

Notice I'm adding yarn installation command at

&& curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - \
&& echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list \
...
&& apt-get install -y nodejs yarn \

After re-building sail sail build --no-cache, it successfully built.

But when I'm running sail yarn install. I got a result

No such command: yarn

Having much curiosity, I'm digging deeper through vendor/laravel/sail/bin/sail file and found that when I'm running sail npm install it just proxying npm command to the npm binary on the application container.

Do you have any solution beside turning down sail then run yarn install locally then turning up sail?
