我有以下docker-compose.yml：

db:
    image: postgres
search:
    image: elasticsearch
web:
    build: .
    working_dir: /code
    environment:
        CATALYST_CONFIG_LOCAL_SUFFIX: development
    volumes:
        - .:/code
    ports:
        - "8000:8000"
    links:
        - db
        - search
    command: carton exec plackup -E development bicycleevents_web.psgi -p 8000

编辑：和以下Dockerfile：

FROM ubuntu:latest

RUN apt-get update
RUN apt-get install -y --force-yes build-essential curl libssl-dev postgresql-client libpq-dev perl-doc
RUN apt-get clean

RUN curl -L https://cpanmin.us | perl - --sudo App::cpanminus
RUN cpanm Carton
RUN mkdir /code
WORKDIR /code
ADD . /code/
RUN rm -rf /code/local/
RUN carton install

如果我运行docker-compose up carton exec …命令失败：

$docker-compose up
...
Starting bicycleeventsweb_web_1

但是,如果我在容器上手动运行相同的命令,它会成功：

$docker run -i -t -e "CATALYST_CONFIG_LOCAL_SUFFIX=development" bicycleeventsweb_web carton exec plackup -E development bicycleevents_web.psgi -p 8000
...
HTTP::Server::PSGI: Accepting connections at http://0:8000/

有关这两个命令之间有什么不同的想法吗？

作为参考,carton就像Bundler for Perl.使用carton exec应该设置Perl环境,以便包含包含所有特定于应用程序的依赖项的相应库路径 – 与docker run命令一起使用.
