Kubernetes : नियंत्रण विमान नोड कॉन्फ़िगर करें2023/10/13 |
|
मल्टी नोड्स Kubernetes क्लस्टर को कॉन्फ़िगर करने के लिए Kubeadm स्थापित करें।
यह उदाहरण निम्न प्रकार से पर्यावरण पर आधारित है।
-----------+---------------------------+--------------------------+------------

eth0|10.0.0.30 eth0|10.0.0.51 eth0|10.0.0.52

कंट्रोल प्लेन नोड पर प्रारंभिक सेटअप कॉन्फ़िगर करें।
[control-plane-endpoint] के लिए, होस्टनाम या IP पता निर्दिष्ट करें जिस पर Etcd और Kubernetes API सर्वर चलाए जाते हैं।
[--pod-network-cidr] विकल्प के लिए, वह नेटवर्क निर्दिष्ट करें जिसका उपयोग Pod नेटवर्क करता है।
पॉड नेटवर्क के लिए कुछ प्लगइन्स हैं। (नीचे विवरण देखें)
⇒ https://kubernetes.io/docs/concepts/cluster-administration/networking/
इस उदाहरण पर, यह Calico का चयन करता है।

[root@dlp ~]# kubeadm init --control-plane-endpoint=10.0.0.30 --pod-network-cidr=192.168.0.0/16 --cri-socket=unix:///var/run/crio/crio.sock
[init] Using Kubernetes version: v1.26.4
[preflight] Running pre-flight checks
[preflight] Pulling images required for setting up a Kubernetes cluster
[preflight] This might take a minute or two, depending on the speed of your internet connection
[preflight] You can also perform this action in beforehand using 'kubeadm config images pull'
[certs] Using certificateDir folder "/etc/kubernetes/pki"
[certs] Generating "ca" certificate and key
[certs] Generating "apiserver" certificate and key
[certs] apiserver serving cert is signed for DNS names [dlp.srv.world kubernetes kubernetes.default kubernetes.default.svc kubernetes.default.svc.cluster.local] and IPs [10.96.0.1 10.0.0.30]

Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
You can now join any number of control-plane nodes by copying certificate authorities
and service account keys on each node and then running the following as root:
kubeadm join 10.0.0.30:6443 --token 3wx2wn.0dkhtd9i26gsrc3t \
--discovery-token-ca-cert-hash sha256:b430cc64408d3349fc368c1d611638a0b71bd10c1ef47254afe414ecfaa200ca \
--control-plane
# क्लस्टर व्यवस्थापक उपयोगकर्ता सेट करें # यदि आप सामान्य उपयोगकर्ता को क्लस्टर व्यवस्थापक के रूप में सेट करते हैं, तो इसके साथ लॉगिन करें और [sudo cp/chown ***] चलाएँ [root@dlp ~]# mkdir -p $HOME/.kube [root@dlp ~]# cp -i /etc/kubernetes/admin.conf $HOME/.kube/config [root@dlp ~]# chown $(id -u):$(id -g) $HOME/.kube/config
