我试图使用一个非常"类似lambda"的映像来运行一些测试，但它是如此类似于lambda，以至于用户没有真正的权限(包括安装我的测试引擎所需的权限(。
有没有办法指定图像执行的用户？
pipeline:
test_lambda:
image: lambci/lambda:python3.6
user: root
resources:
limits:
memory: 128M
commands:
- whoami
- pip install pytest
- py.test
输出。请注意，用户名是sbx_user1051，而不是root
$ drone exec
[test_lambda:L0:0s] + whoami
[test_lambda:L1:0s] sbx_user1051

挑战在于 Docker 卷默认是根目录。因此，为了写入工作区卷(代码克隆到的默认工作目录(，容器用户必须是 root。
有一个实验版本的 git 克隆插件，它试图将目录分配给非特权用户。这将允许具有非特权用户的容器访问工作区，但是，肯定存在一些边缘情况。
您可以使用具有以下语法的实验性 git 插件：
clone:
git:
image: plugins/git:next
pipeline:
test_lambda:
image: lambci/lambda:python3.6
commands:
- pip install pytest
- py.test
提醒一下，仍然存在一些边缘情况，并且仍然不支持非根容器(从版本 0.8 开始(，但是，这可能足以使您的示例正常工作。
