Question

我正在尝试使用此docker映像（https://github.com/continuumsecurity/RopeyTasks）和以下Dockerfile对该Grails应用程序（https://hub.docker.com/r/mozart/grails/）进行Docker化：

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，出现以下错误消息：

我遇到了完全相同的问题！无法找到解决方法，只能使用来自同一映像mozart / grails的基本Dockerfile，并且以某种方式对我有用。

这里是dockerfile，做了一些小的修改：

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，在 BuildConfig.groovy 中添加此存储库

mavenRepo "http://repository.jboss.com/maven2/"
mavenRepo 'http://repo.spring.io/milestone'
mavenRepo "http://repo.grails.org/grails/core"
mavenRepo "http://repo.grails.org/grails/plugins"

尝试对Grails应用程序进行docker化时出错
