我使用gcr.io/cloud-builders/bazel在Google容器构建上构建我的图像。如何加快谷歌云平台上的bazel构建
从日志看来，它似乎花费大部分时间为bazel设置工作区。这个工作空间不会因构建而改变，所以我认为可以预先计算并存储在一个新的图像中。
如何加快Google云端平台上的这些bazel版本？

编辑：添加cloudbuild文件
cloudbuild.yaml：
steps:
- name: gcr.io/cloud-builders/bazel
args: ['run', '//:docker']
- name: gcr.io/cloud-builders/docker
args: ['tag', 'bazel:docker', '${_IMAGE_TAG}']
images: ['${_IMAGE_TAG}']
你如何运行它？发布完整的命令？ –
添加了我正在使用的cloudbuild文件 – fabrizioM
从最初查看所有可用文档的信息可以看出，在这种情况下，缓存或卷没有任何功能可以帮助您。所以最好的是要求Google支持 –
