将 rasa 部署到 App 引擎时出现 Google 云构建权限错误

Question

我正在尝试将此处描述的 rasa 项目部署到谷歌应用引擎，但由于某些权限问题，构建失败

脚本尝试在容器内创建一个文件夹，

FROM rasa/rasa
ENV BOT_ENV=production

COPY . /var/www
WORKDIR /var/www

RUN rasa train

ENTRYPOINT [ "rasa", "run", "-p", "8080"]

我已向 google cloud build 添加了以下权限。

来自云构建的错误日志。

从云 shell 进行gcloud app deploy时也面临同样的问题

我的源代码仓库，需要在运行gcloud app deploy之前删除 cloudbuild.yaml

Answer 1

这是由于 docker 的权限问题，通过添加USER root修复

FROM rasa/rasa
USER root
ENV BOT_ENV=production

COPY . /var/www
WORKDIR /var/www

RUN rasa train

ENTRYPOINT [ "rasa", "run", "-p", "8080"]
