shell - 使用 Docker 部署应用如何执行脚本文件？

Question

我想用 Docker 部署一个 Rails 应用。

Dockerfile 的内容如下：

FROM ruby:2.2.2

ENV APP_HOME /myapp
RUN mkdir $APP_HOME
WORKDIR $APP_HOME

ADD Gemfile $APP_HOME/Gemfile
ADD Gemfile.lock $APP_HOME/Gemfile.lock
ADD init.sh $APP_HOME/

RUN export LANG=C.UTF-8 && bundle install

ADD . $APP_HOME

CMD ["sh", "init.sh"]

init.sh 程序执行脚本内容如下：

#!/bin/sh
bundle exec rake db:setup
bundle exec rake db:seed_fu
bundle exec sidekiq -C config/sidekiq.yml
bundle exec rails server -b 0.0.0.0

当我编译完这个程序镜像：

docker build -t myapp .

运行它时：

docker run --name web -d -p 3000:3000 myapp

从日志中看到：

docker logs web
init.sh: 2: init.sh: bundle: not found
init.sh: 3: init.sh: bundle: not found
init.sh: 4: init.sh: bundle: not found
init.sh: 5: init.sh: bundle: not found

是执行 bundle 的路径问题，怎么指定正确的路径呢？

Answer 1

bundle is not installed. Please install bundle before executing bundle command.

If you are sure and sure that the bundle is installed, it should be a problem with the environment variables, which was not found. Use which bundle to find it and modify the environment variables before executing bundle.
