Kubernetes Ubuntu Deployment

Planning Nodes

Install ubuntu 14.04 LTS

Prepare password-less SSH login

Establish Ssh-key certificate, switch to root account, use command ssh-keygen-t RSA

Generating public/private RSA key pair.

Enter file in which to save the key (/ROOT/.SSH/ID_RSA):

Enter passphrase (empty for no passphrase):

Enter same Passphrase again:

Your identification has been saved In/root/.ssh/id_rsa.

Your public key has been saved in/root/.ssh/id_rsa.pub.

Distribute Id_rsa.pub to authorized_keys inside The root directory of all nodes

Cat/root/.ssh/id_rsa.pub >>/root/.ssh/authorized_keys

or use the Ssh-copy-id command, such as Ssh-copy-id-i/root/.ssh/id_rsa.pub node_ip

Installing, configuring k8s

Download Kubernetes 1.4 official version, address https://github.com/kubernetes/kubernetes/releases/download/v1.4.0/kubernetes.tar.gz

Unzip Kubernetes to/opt/kubernetes

Because the k8s v1.4.0 release does not have a saltbase package, it downloads saltbase content to GitHub, copies it to the/opt/kubernetes/cluster directory, and Saltbase/salt/genera Te-cert/make-ca-cert.sh is set to executable.

Adjust the ubuntu/config-default.conf configuration,

Export nodes=${nodes:-"[email protected]"} modified to node list, node list [email protected] [email protected [email protected] [email protected] separated by a space

roles=${roles:-"AI"} modifies the corresponding rolein the order of the nodes, a means master,i means node, ai means that both Master and node areseparated by spaces

Export Num_nodes=${num_nodes:-1} modified to the number of node lists

under the cluster directory, run the command kubernetes_provider=ubuntu/kube-up.sh start k8s cluster;

Kubernetes_provider=ubuntu./kube-down.sh Stop k8s Cluster

Note:

Run Command Debug=true kubernetes_provider=ubuntu./kube-up.sh Start Debug mode, start the cluster
