Docker 沒有安裝紗線

Question

我正在嘗試像下面這樣運行 docker。 但是即使我安裝了紗線它仍然不起作用。 錯誤運行 rails: yarn not installed 。

Dockerfile ：

FROM rails:on-build
EXPOSE 3000
CMD [ "rails" , "s" , "-b" , "0.0.0.0" , "-p", "3000" ]

rails/Dockerfile ：

FROM ruby:2.6.2
RUN apt-get update -y && apt-get install -y build-essential libpq-dev nodejs sqlite3
ONBUILD COPY app /opt/app
ONBUILD WORKDIR /opt/app
ONBUILD EXPOSE 3000
ONBUILD RUN bundle install
ONBUILD RUN rake db:migrate
ONBUILD RUN rake db:seed

run.sh ：

docker-machine create -d virtualbox Char
eval $(docker-machine env Char)
docker build -t rails:on-build . #this runs ok
docker build -t "thisdir:Dockerfile" . #this command triggers the error

錯誤：

Sending build context to Docker daemon  3.584kB
Step 1/4 : FROM rails:on-build
# Executing 6 build triggers

The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

我嘗試通過在兩個 Dockerfile 的頂部添加以下兩行來安裝紗線，但它仍然無法工作，它有相同的錯誤。

FROM node:6.7.0
RUN npm install -g yarn

Answer 1

使用此更新您的 docker 文件，這將安裝最新版本的 nodejs 和 yarn

RUN curl https://deb.nodesource.com/setup_12.x | bash
RUN curl https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list

RUN apt-get update && apt-get install -y nodejs yarn

Answer 2

嘗試通過apt-get install yarn install yarn 在你的鏡像中apt-get install yarn並在安裝 gems 之前運行yarn install

Answer 3

如果單線不適合你......

RUN curl https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -

你可以把它分成兩步

ADD https://dl.yarnpkg.com/debian/pubkey.gpg /tmp/yarn-pubkey.gpg
RUN apt-key add /tmp/yarn-pubkey.gpg && rm /tmp/yarn-pubkey.gpg
