Google 将 rasa 部署到 App Engine 时出现云构建权限错误

Question

我正在尝试将描述为 here 的 rasa 项目部署到 google 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"]

我已将以下权限添加到 google 云构建。

从云端 gcloud app deploy 时也面临同样的问题 shell

my repo的源代码， 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，已通过添加 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"]
