Steps to reproduce

Hello,
I'm using Minikube (Kubernetes dev environment).
So my vue application run in a container (pod).
My Minikube version is v1.9.2

What is expected?

After an upgrade to minikube v1.9.2
I noticed that the checkInContainer return false instead of true !

https://github.com/vuejs/vue-cli/blob/dev/packages/%40vue/cli-service/lib/commands/serve.js#L344

Indeed with my old version of Minikube (v1.4.0) the output of /proc/1/cgroup was:

bash-5.0# cat /proc/1/cgroup
11:hugetlb:/kubepods/besteffort/pode62a77e6-9d4b-4974-8376-8bb98df015bb/2e26a995b0f0108a688b6b30b24bc424cc95efc20c1a59827ef0bad5e66f9c67
10:perf_event:/kubepods/besteffort/pode62a77e6-9d4b-4974-8376-8bb98df015bb/2e26a995b0f0108a688b6b30b24bc424cc95efc20c1a59827ef0bad5e66f9c67

So it's was good, and checkInContainer return true.

But now with minikube v1.9.2:

bash-5.0# cat /proc/1/cgroup

11:perf_event:/kubepods.slice/kubepods-besteffort.slice/kubepods-besteffort-pod4877e3c2_9915_4991_aa79_cd978f8b89e9.slice/docker-605ec9359d21c5b9fe4e5d511b1edb496e9f53f631a6a48a4798c08021e8b4d9.scope
10:freezer:/kubepods.slice/kubepods-besteffort.slice/kubepods-besteffort-pod4877e3c2_9915_4991_aa79_cd978f8b89e9.slice/docker-605ec9359d21c5b9fe4e5d511b1edb496e9f53f631a6a48a4798c08021e8b4d9.scope

What is actually happening?

It's return false instead of true, the regex need to be upgraded to support the new output of the /proc/1/cgroup
and need to grep "kubepods.slice" ?

[sraillard]

The current regex used in the function checkInContainer is searching for patterns like /docker/, /kubepods/ and /lxc/. The cgroup names are changing a lot with the different Kuebernetes or Docker versions used. Maybe a less restrictive regex can be used, only searching for the keywords without the /?

[sraillard]

A quick contribution: replacing return /:\/(lxc|docker|kubepods)\//.test(content) by return /(lxc|docker|kubepods)/.test(content) in serve.js is fixing the issue (tested with Kubernetes version 1.18.2).

Anyone can contribute? This would be my first contribution to OSS
