一、准备Dockerfile文件。

FROM hub.c.163.com/library/centos:latest

RUN echo "Asia/shanghai" > /etc/timezone;
RUN cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

COPY nginx-1.8.1.sh /usr/local/
COPY run.sh /usr/local

二、创建 nginx-1.8.1.sh 安装脚本。

#!/bin/bash
#install nginx-1.8.1

#安装目录
INSTALL_DIR=/opt/
SRC_DIR=/opt/software

[ ! -d ${INSTALL_DIR} ] && mkdir -p ${INSTALL_DIR}
[ ! -d ${SRC_DIR} ] && mkdir -p ${SRC_DIR}

# Check if user is root
if [ $(id -u) != "0" ]; then
    echo "Error: You must be root to run this script!!"
    exit 1
fi

#安装依赖包
for Package in unzip wget gcc gcc-c++ autoconf automake zlib zlib-devel openssl openssl-devel pcre pcre-devel
do
    yum -y install $Package
done

Install_Nginx()
{
#更新版本信息
NGINX="nginx-1.8.1"
PCRE="pcre-8.35"
ZLIB="zlib1211"
OPENSSL="openssl-1.0.1i"

NGINXFEATURES="--prefix=${INSTALL_DIR}nginx \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_gzip_static_module \
--with-http_stub_status_module \
--with-http_realip_module \
--pid-path=/var/run/nginx.pid \
--with-pcre=${SRC_DIR}/${PCRE} \
--with-zlib=${SRC_DIR}/zlib-1.2.11 \
--with-openssl=${SRC_DIR}/${OPENSSL}
"

cd ${SRC_DIR}
#下载所需安装包
echo 'Downloading NGINX'
if [ ! -f ${NGINX}.tar.gz ]
then
  wget -c https://nginx.org/download/${NGINX}.tar.gz
else
  echo 'Skipping: NGINX already downloaded'
fi

echo 'Downloading PCRE'
if [ ! -f ${PCRE}.tar.gz ]
then
  wget -c https://sourceforge.net/projects/pcre/files/pcre/8.35/${PCRE}.tar.gz
else
  echo 'Skipping: PCRE already downloaded'
fi

echo 'Downloading ZLIB'
if [ ! -f ${ZLIB}.zip ]
then
  wget -c https://zlib.net/${ZLIB}.zip
else
  echo 'Skipping: ZLIB already downloaded'
fi

echo 'Downloading OPENSSL'
if [ ! -f ${OPENSSL}.tar.gz ]
then
  wget -c https://www.openssl.org/source/${OPENSSL}.tar.gz
else
  echo 'Skipping: OPENSSL already downloaded'
fi

echo '----------Unpacking downloaded archives. This process may take serveral minutes---------'

echo "Extracting ${NGINX}..."
tar xzf ${NGINX}.tar.gz
echo 'Done.'

echo "Extracting ${PCRE}..."
tar xzf ${PCRE}.tar.gz
echo 'Done.'

echo "Extracting ${ZLIB}..."
unzip ${ZLIB}.zip
echo 'Done.'

echo "Extracting ${OPENSSL}..."
tar xzf ${OPENSSL}.tar.gz
echo 'Done.'

#添加用户
groupadd -r nginx
useradd -r -g nginx nginx

#编译
echo '###################'
echo 'Compile NGINX'
echo '###################'
cd ${SRC_DIR}/${NGINX}
./configure ${NGINXFEATURES}
make
make install
cd ../

mkdir -p ${INSTALL_DIR}/nginx/conf/vhosts

}

Install_Nginx

三、创建运行脚本 run.sh

#!/bin/bash
source /etc/profile

echo `pwd`

sh /usr/local/nginx1.8.sh

/usr/local/nginx/sbin/nginx

while true; do sleep 1; done

四、构建

docker build -t nginx:0.1 .

五、准备yaml文件 nginx.yaml

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  minReadySeconds: 10
  template:
    metadata:
      labels:
        app: nginx
        version: V20170907134852
    spec:
      volumes:
        - name: logs
          hostPath:
            path: /data/log
        - name: jdk
          hostPath:
            path: /usr/local/java/jdk1.8.0_102
        - name: project
          hostPath:
            path: /data/appdeploy
      containers:
        - name: nginx
          image: nginx:0.1
          ports:
            - containerPort: 80
          volumeMounts:
          - mountPath: /data/log
            name: logs
          - mountPath: /usr/local/java/jdk1.8.0_102
            name: jdk
            readOnly: true
          - mountPath: /data/appdeploy
            name: project
          env:
            - name: DEPLOYMENT_DEMO_VER
              value: V20170907134852
          command:
            - /usr/local/run.sh
---
apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    app: nginx
spec:
  type: NodePort
  selector:
    app: nginx
  ports:
  - name: http
    port: 80
    nodePort: 80
    targetPort: 80
    protocol: TCP
  selector:
    app: nginx

六、启动yaml

kubectl create -f y nginx.yaml

大功告成!
