我正在尝试使用此docker镜像(https://hub.docker.com/r/mozart/grails/(和以下Dockerfile对这个Grails应用程序(https://github.com/continuumsecurity/RopeyTasks(进行Dockerization：
FROM mozart/grails:2
MAINTAINER Manuel Ortiz Bey <ortiz.manuel@mozartanalytics.com>
# Copy App files
COPY . /app
# Run Grails refresh-dependencies command to
# pre-download dependencies but not create
# unnecessary build files or artifacts.
RUN grails refresh-dependencies
# Set Default Behavior
ENTRYPOINT ["grails"]
CMD ["run-app"]
但是当我运行命令docker run -it -p 8080:8080 test/grails-app时，我收到以下错误消息：

感谢您的帮助！
我遇到了完全相同的问题！找不到绕过它的方法，只能使用来自相同图像 mozart/grails 的基本 Dockerfile，并且以某种方式对我有用。
这是经过一些小修改的 dockerfile：
FROM java:8
# Set Grails version (min: 3.0.0; max: 3.2.8).
ENV GRAILS_VERSION 2.4.5
# Install Grails
WORKDIR /usr/lib/jvm
RUN wget https://github.com/grails/grails-core/releases/download/v$GRAILS_VERSION/grails-$GRAILS_VERSION.zip &&
unzip grails-$GRAILS_VERSION.zip && rm -rf grails-$GRAILS_VERSION.zip && ln -s grails-$GRAILS_VERSION grails
# Setup Grails path.
ENV GRAILS_HOME /usr/lib/jvm/grails
ENV PATH $GRAILS_HOME/bin:$PATH
# Create App Directory
RUN mkdir /app
# Copy App files
COPY . /app
# Set Workdir /app and download dependecies
WORKDIR /app
RUN grails refresh-dependencies
# Make port 8080 available to the world outside this container
EXPOSE 8080
# Set Default Behavior
ENTRYPOINT ["grails"]
CMD ["run-app"]
我遇到了同样的问题，请在BuildConfig.groovy中添加此存储库
