我想使用docker来部署rails应用程序.
我按照官方教程做了：
https://docs.docker.com/compose/rails/
但似乎我不幸运.
我的Dockerfile
FROM ruby:2.2.2
RUN apt-get update -qq && apt-get install -y build-essential
# for MysqL
RUN apt-get install -y MysqL-client libMysqLclient-dev
# for a JS runtime
RUN apt-get install -y nodejs
ENV APP_HOME /myapp
RUN mkdir $APP_HOME
WORKDIR $APP_HOME
ADD Gemfile $APP_HOME/Gemfile
ADD Gemfile.lock $APP_HOME/Gemfile.lock
RUN bundle install
ADD . $APP_HOME
我的docker-compose.yml
db:
image: MysqL
ports:
- "3306:3306"
web:
build: .
command: bundle exec rails s -p 3000 -b '0.0.0.0'
volumes:
- .:/myapp
ports:
- "3000:3000"
links:
- db
运行docker-compose build后,它显示：
...

怎么了？
最佳答案
查看“bundle install error “invalid byte sequence in US-ASCII (ArgumentError)””中的类似错误,一个选项是广告到Dockerfile：
原文链接：https://www.f2er.com/docker/435732.htmlexport LANG=C.UTF-8
例如,见this Dockerfile.
# Install required packages
# LANG=C.UTF-8 line is needed for ondrej/PHP5 repository
RUN \
export LANG=C.UTF-8 && \
...
