Complete!

因为我们要使用单机模式,所以我们直接忽略掉认证相关设置,把置文件中的 KUBE_ADMISSION_CONTROL 整行注释掉

[root@localhost ~]# vi /etc/kubernetes/apiserver
#KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota"

然后启动 kubernetes 需要用到的服务

[root@localhost ~]# systemctl enable docker etcd kube-apiserver kube-controller-manager kubelet kube-proxy kube-scheduler
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

Created symlink from /etc/systemd/system/multi-user.target.wants/kube-scheduler.service to /usr/lib/systemd/system/kube-scheduler.service.
[root@localhost ~]# systemctl start docker etcd kube-apiserver kube-controller-manager kubelet kube-proxy kube-scheduler

服务器启动后,我们提前把需要用到的镜象拽回来,否则因为各种网络问题,容器可能一直无法启动,你又不知道卡在哪里,提前拽回来可以让你更好地测试:

[root@localhost ~]# docker pull registry.access.redhat.com/rhel7/pod-infrastructure:latest
Trying to pull repository registry.access.redhat.com/rhel7/pod-infrastructure ... 
latest: Pulling from registry.access.redhat.com/rhel7/pod-infrastructure

[root@localhost ~]# docker pull nginx:alpine
Trying to pull repository docker.io/library/nginx ... 
alpine: Pulling from docker.io/library/nginx
Digest: sha256:33eb1ed1e802d4f71e52421f56af028cdf12bb3bfff5affeaf5bf0e328ffa1bc

然后启动 nginx:alpine 容器

[root@localhost ~]# kubectl run nginx --image=nginx:alpine
deployment "nginx" created
[root@localhost ~]# kubectl get pods
NAME                    READY     STATUS    RESTARTS   AGE
nginx-738041155-jqbcz   1/1       Running   0          1m

再让 nginx 服务对外暴露

[root@localhost ~]# kubectl expose deployment nginx --type=NodePort --port=80
service "nginx" exposed
[root@localhost ~]# kubectl get services
NAME         CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
kubernetes   10.254.0.1             443/TCP        1h
nginx        10.254.199.2          80:30837/TCP   2m

可以看到分配到的集群 IP 是 10.254.199.2

[root@localhost ~]# curl http://10.254.199.2
