建立專案

1.建立一個springboot專案 pas。隨便寫一個Controller類：

	@RequestMapping(value = "/oauth")
	public void authentication(HttpServletRequest request,
			HttpServletResponse response) {

     。。。。。
 }

2.打包部署pas。部署到linux 。目錄結構如下：

[[email protected] pas]# ll
total 80
drwxr-xr-x 2 root root  4096 Sep  3 16:41 config
drwxr-xr-x 2 root root  4096 Sep  2 18:59 lib
-rw-r--r-- 1 root root 67926 Aug 28 10:59 pas-1.0.0.jar
 

java -jar pas-1.0.0.jar  &
[1] 10390
[[email protected] pas]# 2017-09-03 17:15:22.066 [main] INFO  com.wtsd.pas.PasApplication - Starting PasApplication v1.0.0 on localhost with PID 10390 (/scss/pas/pas-1.0.0.jar started by root in /scss/pas)

[[email protected] pas]# tar -zcvf pas.tar.gz pas/

建立映象

1.首先建立並進入/opt/pas 資料夾。建立Dockerfile 檔案：

# This is  my first web project with Docker.
FROM openjdk:8-jdk-alpine
#將專案包複製到映象/usr/local目錄下
ADD pas.tar.gz /usr/local/
ENV JAVA_OPTS=""
#暴露84埠
EXPOSE 84
#切換工作目錄
WORKDIR  /usr/local/pas/
ENTRYPOINT ["sh","-c","java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar  pas-1.0.0.jar"]
 

[[email protected] pas]# ll
total 24244
-rw-r--r-- 1 root root      273 Sep  3 17:43 Dockerfile
drwxr-xr-x 2 root root     4096 Sep  3 15:57 config
drwxr-xr-x 2 root root     4096 Sep  3 18:09 logs
-rw-r--r-- 1 root root 24784743 Sep  3 16:41 pas.tar.gz

3. docker build -t chenyaochn/pas .構建映象  如下顯示：

部署

部署zookeeper

1.從docker hub上下載最新zookeeper映象。

[[email protected] ~]# docker pull zookeeper 
Using default tag: latest

可以將，zookeeper conf/目錄掛載到宿主伺服器，容器和宿主伺服器共享zoo.cfg配置檔案，方便對zookeeper配置的修改。

2.執行

[[email protected] ~]# docker run  -d -p 2181:2181 --name zookeeper zookeeper

部署springboot專案

#釋出84埠， 建立兩個卷，一個是配置檔案目錄，一個是日誌檔案目錄
[[email protected] pas]# docker run -p 84:84 -v /opt/pas/config/:/usr/local/pas/config  -v  /opt/pas/logs/:/usr/local/pas/logs/ --name pas chenyaochn/pas
