I've looked at How does one install the kube-dns addon for minikube? but the issue is that in that question, the addon is installed. However when I write

none of which is kube-dns. Can't find instructions anywhere as it's supposed to be there by default, so what have I missed?
编辑，这是在Ubuntu 18.04上运行的minikube v1.0.1.
EDIT This is minikube v1.0.1 running on Ubuntu 18.04.
推荐答案
您所指的StackOverflow案例是在2017年，因此有点过时了.
The StackOverflow case which you are referring to was in 2017 so it's bit outdated.
根据文档建议使用CoreDNS替换了kube-dns的DNS服务器.有一个过渡时期，即同时并行部署KubeDNS和CoreDNS，但是在最新版本中，仅部署了CoreDNS.
According to documentation CoreDNS is recommended DNS server which replaced kube-dns. There was a transitional period when both KubeDNS and CoreDNS were deployed parallel, however in latest version only CoreDNS is deployed.
默认情况下，Minikube使用CoreDNS创建2个容器.验证执行:
As default Minikube is creating 2 pods with CoreDNS. To verify execute:
$ kubectl get pods -n kube-system
NAME READY STATUS RESTARTS AGE
coredns-5c98db65d4-g4vs2 1/1 Running 1 20m
coredns-5c98db65d4-k4s7v 1/1 Running 1 20m
etcd-minikube 1/1 Running 0 19m
kube-addon-manager-minikube 1/1 Running 0 20m
kube-apiserver-minikube 1/1 Running 0 19m
kube-controller-manager-minikube 1/1 Running 0 19m
kube-proxy-thbv5 1/1 Running 0 20m
kube-scheduler-minikube 1/1 Running 0 19m
storage-provisioner 1/1 Running 0 20m
您还可以看到已经部署了CoreDNS.
You can also see that there is CoreDNS deployment.
$ kubectl get deployments coredns -n kube-system
NAME READY UP-TO-DATE AVAILABLE AGE
coredns 2/2 2 2 37m
在这里两个DNS之间的比较.
Here you can find comparison between both DNS.
因此，简而言之，您什么都没错过. minikube start期间默认部署CoreDNS.
So in short, you did not miss anything. CoreDNS is deployed as default during minikube start.
