错误：运行docker容器时无法访问jarfile [英] Error: Unable to access jarfile when running docker container

问题描述

尝试运行docker容器时出现以下错误：

I am getting the following error when trying to run a docker container:

Error: Unable to access jarfile

我的Dockerfile是这样的：

My Dockerfile is like this:

FROM ubuntu:16.04

# Install Updates
RUN apt-get update -y && \
     apt-get upgrade -y && \
     apt-get install -y software-properties-common && \
     apt-add-repository -y ppa:openjdk-r/ppa && \
     apt-get update -y && \
     rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /var/cache/*

# Install Packages
RUN apt-get -qq update -y && \
    apt-get -q install -y \
        wget \
        openssh-server \
        openjdk-8-jdk \
        && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /var/cache/*

# Add the config files
ADD /apps/ /home/smartling/

# Adding the jar application
ADD /apps/flagship/repo-connector-1.5.4/repo-connector-1.5.4.jar /home/smartling/flagship/repo-connector-1.5.4/

# Making sure the files are there
RUN ls -la /home/smartling/flagship/repo-connector-1.5.4/

# Start the jar file when container launches
CMD ["java","-jar","/home/smartling/flagship/repo-connector-1.5.4/repo-connector-1.5.4.jar -start&"]

然后我建立

docker build -t smartlingflagship .

一切都恢复成功

我运行容器

docker run --rm --name smartlingconn smartlingflagship

它返回时出现以下错误：

And it comes back with the following error:

Error: Unable to access jarfile /home/smartling/flagship/repo-connector-1.5.4/repo-connector-1.5.4.jar -start&

我错过了什么吗？

推荐答案

我能够通过将其添加到底部 ENTRYPOINT [java， - jar，repo-connector-1.5.4.jar]来解决这个问题。
CMD [-start]

I was able to resolve this by adding this to the bottom ENTRYPOINT ["java","-jar","repo-connector-1.5.4.jar"] CMD ["-start"]
