无法设置流量 - gcloud

Question

所以，

我更新了 gcloud 组件。我一直在使用以下内容，但现在失败了：

gcloud app modules set-default default --version my-version --project my-proj

所以我尝试了：

gcloud app services set-traffic --project my-proj --splits my-version=1 --migrate

但我得到以下输出：

Setting the following traffic allocations:
 - my-proj/default/my-version: 1.0
Any other versions on the specified services will receive zero traffic.
ERROR: (gcloud.app.services.set-traffic) Issue setting traffic on service(s): default

INVALID_ARGUMENT: Invalid request.

有什么想法会出错吗？

提前致谢， 呵呵

Answer 1

您是否正在尝试将流量迁移到您的 gcp app engine 的新版本？

gclouddocumentation

此命令将立即将流量迁移到指定的版本：

gcloud app services set-traffic MY_SERVICE --splits MY_VERSION=1

或者您可以按百分比（verion1=30% 和 version2=70%）拆分：

gcloud app services set-traffic MY_SERVICE --splits MY_VERSION_V1=0.3,MY_VERSION_V2=0.7

Answer 2

引用GAE documentation：

不支持在柔性环境中运行的版本之间的渐进式流量迁移流量。您必须立即将流量迁移到在柔性环境中运行的版本。
