阅读documentation on autoscaling当使用docker + machine作为执行者时,我无法确定[runner.docker]部分的作用:
[runners.docker]
image = "ruby:2.1" # The default image used for builds is 'ruby:2.1'
docker + machine:与docker一样,但使用自动缩放的docker机器 - 这需要[runners.docker]和[runners.machine]
的存在
我得知我必须定义这个[runners.docker]部分才能使用[runners.machine]部分,但这个[runners.docker]的目的是什么? 我找不到如何配置它,因为我不明白为什么要使用它。
我们的gitlab-runner在vSphere VM上运行,并配置为使用docker + machine executor和MachineDriver使用vmwarevsphere进行扩展。一切都很好,但我想完全理解配置文件。
这是我们用“runners.docker”审查的“带星星审查”的config.toml文件我无法理解(请注意,编写它的人离开公司,所以我不能问他):

output_limit = 102400

[runners.machine]
部分定义了如何启动和配置您的跑步机,然后[runners.docker]
部分定义如何配置跑步者机。
Docker-machine本身只执行以下操作(因为您可以阅读here):
“Docker Machine是一个工具,可让您在虚拟主机上安装Docker Engine,并使用docker-machine命令管理主机。”
所以这对Gitlab运行器没有任何作用,你仍然需要在那之后配置运行器以及[runners.docker]
部分发挥作用的地方,因为运行器需要知道要使用的默认映像和要安装的卷等
