Ubuntu 14.04主机上部署K8S集群

部署结构

1. 3台虚拟机，其中1台作为master，2台作为minion，都安装了最新版本的docker engine（目前是1.11.2)
2. k8s版本是1.3.0

部署步骤

1. 在部署机上下载k8s，并编译。

部署机需要安装docker engine(1.11.2)和go(1.6.2)

$git clone https://github.com/kubernetes/kubernetes.git
$cd kubernetes
$make release-skip-tests
$mv _output/release-stage/full/kubernetes/server/kubernetes-server-linux-amd64.tar.gz cluster//

Note

除了linux/amd64，默认还会为其他平台做交叉编译。为了减少编译时间，可以修改hack/lib/golang.sh，把KUBE_SERVER_PLATFORMS， KUBE_CLIENT_PLATFORMS和KUBE_TEST_PLATFORMS中除linux/amd64以外的其他平台注释掉。

2. 下载etcd,flannel安装包

$ETCD_VERSION=${ETCD_VERSION:-"2.3.1"}
$ETCD="etcd-v${ETCD_VERSION}-linux-amd64"
$curl -L https://github.com/coreos/etcd/releases/download/v${ETCD_VERSION}/${ETCD}.tar.gz -o cluster/ubuntu/etcd.tar.gz
 
$FLANNEL_VERSION=${FLANNEL_VERSION:-"0.5.5"}
$curl -L  https://github.com/coreos/flannel/releases/download/v${FLANNEL_VERSION}/flannel-${FLANNEL_VERSION}-linux-amd64.tar.gz -o cluster/ubuntu/flannel.tar.gz

 3. 解压缩安装包

$cd cluster/ubuntu
$mkdir -p binaries/master
$mkdir -p binaries/minion
 
$ tar xzf etcd.tar.gz
$ cp ${ETCD}/etcd ${ETCD}/etcdctl binaries/master
$ echo ${ETCD_VERSION} > binaries/.etcd
 
$tar xzf flannel.tar.gz
$cp flannel-${FLANNEL_VERSION}/flanneld binaries/master
$cp flannel-${FLANNEL_VERSION}/flanneld binaries/minion
$echo ${FLANNEL_VERSION} > binaries/.flannel
 
$KUBE_VERSION=1.3.0
$tar xzf kubernetes-server-linux-amd64.tar.gz
$cp kubernetes/server/bin/kube-apiserver kubernetes/server/bin/kube-controller-manager kubernetes/server/bin/kube-scheduler binaries/master
$cp kubernetes/server/bin/kubelet kubernetes/server/bin/kube-proxy binaries/minion
$cp kubernetes/server/bin/kubectl binaries/
$echo ${KUBE_VERSION} > binaries/.kubernetes

4. 安装

$ cd ../
 
$export nodes="[email protected] [email protected] [email protected]"
$export role="ai i i"
$export NUM_NODES=${NUM_NODES:-3}
$export SERVICE_CLUSTER_IP_RANGE=192.168.3.0/24
$export FLANNEL_NET=172.16.0.0/16
 
$KUBERNETES_PROVIDER=ubuntu ./kube-up.sh
