Azure ACR 任务无法从 Azure 容器注册表中提取 docker 镜像

Question

我正在关注this文章。我有一个 Azure 容器注册表，如下图所示，并且我已定义如下任务。

az acr task create \
--name krushnaTask \
--registry krushna \
--cmd python-hello \
--schedule "1 10 * * *" \
--context /dev/null

当 Azure 运行任务时，它给出以下错误:

2020/06/02 11:02:03 Alias support enabled for version >= 1.1.0, please see https://aka.ms/acr/tasks/task-aliases for more information.

如何才能让 ACR 任务访问 docker 镜像？

Answer 1

我很确定问题是您需要将图像输入为 krushna.azurecr.io/python-hello:tag 因为该图像位于您的 ACR 中。当你输入的镜像为 python-hello 时，意味着它是 Docker hub 中的公共(public) docker 镜像，因此会因为在 Docker hub 中找不到该镜像而导致错误。像下面这样更改命令，它会正常工作:

az acr task create \
--name krushnaTask \
--registry krushna \
--cmd krushna.azurecr.io/python-hello \
--schedule "1 10 * * *" \
--context /dev/null
