HelloWorld Apama Docker应用程序

Question

我正在尝试使用apama-builder构建一个简单的HelloWorld docker镜像。然而，我得到了以下错误：

INFO: copying the project file from /app/HelloWorld to output directory /app/deployed
ERROR: Failed to create correlator initialization list: /app/deployed
The command '/bin/sh -c engine_deploy --outputDeployDir /app/deployed /app/HelloWorld' returned a non-zero code: 100

我的Docker文件如下所示：

# Use the build environment
FROM store/softwareag/apama-builder:10.3 as builder

# Copy project assets into build environment
COPY --chown=1724:1724 . /app/HelloWorld

# Deploy the apama project
RUN engine_deploy --outputDeployDir /app/deployed /app/HelloWorld

# Add any additional build steps you may have, such as building plugins, here
# RUN ...

# Final image is based on the runtime base image
FROM store/softwareag/apama-correlator:10.3

# Copy deployed project from the build environment
COPY --chown=1724:1724 --from=builder /app/deployed /app/deployed

# Add copies for any additional build artifacts created in the build environment
# COPY --from=builder ...

WORKDIR /app

# Run the deployed project
CMD ["correlator", "--config", "Project_deployed", "--logfile", "/dev/stdout"]

注意，我使用的是CentOS，我的HelloWorld应用程序位于/app/HelloWorld，我希望输出位于/app/deployed。

有几个问题，但它源于部署进程不是以root用户身份运行的事实，因此无法创建输出目录。它最初也愚弄了我:)

首先，

# Copy project assets into build environment
COPY --chown=1724:1724 . /app/HelloWorld

工作，但engine_deploy不能，因为它不能访问/app/deployed

因此，如果将engine_deploy行更改为

RUN engine_deploy --outputDeployDir ${APAMA_WORK}/deployed /app/HelloWorld

它将在“工作”目录中创建可运行的应用程序部署，通常为/apama_work

现在，因为它不是您放置它的位置，所以您需要更改构建器中的副本

# Copy deployed project from the build environment
COPY --chown=1724:1724 --from=builder ${APAMA_WORK}/deployed ${APAMA_WORK}/deployed

最后，CMD线需要更改

# Run the deployed project
CMD ["correlator", "--config", "deployed", "--logfile", "/dev/stdout"]

匹配输出目录
