Concourse Quickstart Docker权限错误

Question

我尝试按照documentation在本地设置Concourse CI。在我尝试运行示例hello-world管道之前，一切都很顺利。该作业导致此错误...

runc create: exit status 1: container_linux.go:264: starting container process caused "process_linux.go:339: container init caused \"rootfs_linux.go:56: mounting \\\"/worker-state/3.8.0/assets/bin/init\\\" to rootfs \\\"/worker-state/volumes/live/a8d3b403-19e7-4f16-4a8a-40409a9b017f/volume/rootfs\\\" at \\\"/worker-state/volumes/live/a8d3b403-19e7-4f16-4a8a-40409a9b017f/volume/rootfs/tmp/garden-init\\\" caused \\\"open /worker-state/volumes/live/a8d3b403-19e7-4f16-4a8a-40409a9b017f/volume/rootfs/tmp/garden-init: permission denied\\\"\""

看起来我收到了权限错误，但我已经仔细检查了容器是否以特权模式运行。

$ docker inspect --format='{{.HostConfig.Privileged}}' concourse_concourse_1
true

虽然表面上的所有内容看起来都像是最新的。重要的是要注意docker-machine在VM内部运行docker，如果您不定期更新它们，并且Concourse需要内核3.19或更高版本，则可能会过时。

运行docker info可以从Docker服务器的角度阐明这种情况。

对我有用的是......

$ docker-compose down
$ docker-machine upgrade
$ docker-compose up -d
