bazel的远程工作者指南(here)解释了如何在本地启动远程工作者,然后对其运行bazel。
我尝试了它确实有效(带有reported in GH)
的错误另一种尝试是在虚拟的独立机器上创建运行远程工作器,方法是在docker容器内运行并运行bazel。但它以不同的方式失败了 - 我想这次我错了。
这是我的泊坞文件:
FROM openjdk:8
# install release bazel from apt
RUN echo "deb [arch=amd64] http://storage.googleapis.com/bazel-apt stable jdk1.8" | tee /etc/apt/sources.list.d/bazel.list
RUN curl https://bazel.build/bazel-release.pub.gpg | apt-key add -
RUN apt-get update && apt-get install -y zip bazel
# compile dev bazel from sources
RUN mkdir -p /usr/src/bazel
# "bazel" has the latest development code of bazel from github
COPY bazel /usr/src/bazel
WORKDIR /usr/src/bazel
RUN bazel build src/bazel
# compile remote_worker using latest development bazel
RUN bazel-bin/src/bazel build //src/tools/remote_worker
# prepare cache folder
RUN mkdir -p /tmp/test
# Run remote-worker
CMD ["bazel-bin/src/tools/remote_worker/remote_worker","--work_path=/tmp/test","--listen_port=3030"]
构建它之后,我只需运行将端口绑定到localhost的docker:
$ docker build -t bazel-worker .
$ docker run -p 3030:3030 bazel-worker
然后运行bazel java test以使用远程worker运行: (可以查看我的测试报告here)
$ bazel --host_jvm_args=-Dbazel.DigestFunction=SHA1 test \
--spawn_strategy=remote \
--remote_executor=localhost:3030 \
--remote_cache=localhost:3030 \
--strategy=Javac=remote \
--remote_local_fallback=false \
--remote_timeout=600 \
//src/main/java/com/example/...
但是我收到了这个奇怪的错误信息:

我做错了吗?在实际(或虚拟)远程计算机上运行远程工作程序时,是否需要以不同方式运行它(而不是仅在本地运行)?
重要提及:我的机器是mac osx sierra
。 ,我相信docker openjdk:8
是基于ubuntu的,我正在运行本地bazel开发版本(sha 956810b6ee24289e457a4b8d0a84ff56eb32c264
)。
答案 0 :(得分:4)
在与Bazel本身不同的架构/操作系统组合上运行远程工作者还没有工作。我们在Bazel还有几个地方,我们检查当地的机器 - 它们是作为临时措施添加的,但尚未修复。
编辑:它可能在某些情况下有效,特别是对于与平台无关的代码(例如,Java或Scala)。
如果你的构建测试很重,你可以尝试只使用--test_strategy = remote远程运行测试;不过,我不确定默认的Jvm配置是否可行。
如果您想远程运行整个构建,那么您需要告诉Bazel它正在执行哪种机器/操作系统。现在,需要设置--host_cpu,并且可能需要--crosstool_top / --host_crosstool_top来为该平台配置C ++编译器。
此外,平台的某些组合更多,而且一些不太可能起作用。特别是,结合MacOS和Linux或不同版本的Linux在任何组合中都比Windows更有效。
