制作自己的javaweb镜像

1.制作自己的基于tomcat、mysql的镜像

 1.拉取tomcat镜像并基于tomcat构造自己的镜像

 　　tomcat镜像的运行需要用到java，所以tomcat的镜像包含了JDK，我们不用单独拉取JDK。

(1)到网站 https://c.163.com/hub#/library/search?keyword=tomcat  查找tomca镜像

 

(2)拉取tomcat镜像

Administrator@MicroWin10-1535 MINGW64 /e/docker/dockerTest/dockertest3
$ docker pull hub.c.163.com/library/tomcat:latest

查看tomcat镜像：

Administrator@MicroWin10-1535 MINGW64 /e/docker/dockerTest/dockertest3
$ docker images|grep tomcat
hub.c.163.com/library/tomcat   latest              72d2be374029        2 years ago         292MB

 

 (3)准备一个war包(JavaWeb项目)：

Administrator@MicroWin10-1535 MINGW64 /e/docker/dockerTest/dockertest3
$ pwd
/e/docker/dockerTest/dockertest3

Administrator@MicroWin10-1535 MINGW64 /e/docker/dockerTest/dockertest3
$ ls
Dockerfile  ssm.war

　　ssm.war是一个SSM项目。用到mysql数据库。

 

(4)编写Dockerfile

我们到tomcat查看镜像说明文档：文档中给了镜像中默认的一些环境变量。

 

编写Dockerfile，位置与ssm.war在同一目录。内容如下：

复制代码
Administrator@MicroWin10-1535 MINGW64 /e/docker/dockerTest/dockertest3
$ ls
Dockerfile  SSM.war

Administrator@MicroWin10-1535 MINGW64 /e/docker/dockerTest/dockertest3
$ cat Dockerfile
FROM hub.c.163.com/library/tomcat
MAINTAINER qlq
COPY ssm.war /usr/local/tomcat/webapps
复制代码

 　　Dockerfile中指定镜像基于tomcat镜像，将ssm.war拷贝到tomcat/webapps/目录下，也就是部署目录。

 

(5)build镜像

复制代码
Administrator@MicroWin10-1535 MINGW64 /e/docker/dockerTest/dockertest3
$ docker build -t ssm:latest .
Sending build context to Docker daemon  57.06MB
Step 1/3 : FROM hub.c.163.com/library/tomcat

复制代码

 

(6)查看自己制作的镜像

复制代码
$ docker images
REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE
ssm                            latest              e8b3d5931a30        11 minutes ago      350MB
hello_dockerfile               latest              779eab29d6dc        3 days ago          5.59MB
alpine                         latest              e7d92cdc71fe        4 weeks ago         5.59MB
ubuntu                         latest              ccc6e87d482b        4 weeks ago         64.2MB
hello-world                    latest              fce289e99eb9        13 months ago       1.84kB
hub.c.163.com/library/tomcat   latest              72d2be374029        2 years ago         292MB
hub.c.163.com/library/nginx    latest              46102226f2fd        2 years ago         109MB
复制代码

 

2. 启动自己制作的镜像

$ docker run -d -p 8080:8080 ssm
a6dc2ffbfa1d81c883a47031a39fb31ab689378c3415bcfabd75db8acec28505

浏览器访问：可以看到tomcat已经启动成功

 

 3.拉取mysql镜像并启动

1.拉取mysql镜像

 docker pull hub.c.163.com/library/mysql:latest

 

2.查看mysql镜像使用手册

查看官方文档支持的变量如下：

 

3.启动mysql

$ docker run --name mysql-ssm -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=ssm -d hub.c.163.com/library/mysql
87dac70556a4466fbf452436cb0a3bf19c9915fa6201b6b9b28680f922cb9823

-e MYSQL_ROOT_PASSWORD 指定root的密码。-e MYSQL_DATABASE=ssm指定创建的数据库实例。

 

4.进入mysql容器查看信息(需要从虚拟linux主机进入)

复制代码
Administrator@MicroWin10-1535 MINGW64 /e/docker/dockerTest/dockertest3
$ docker-machine ssh #进入虚拟linux机器

复制代码

　　发现mysql的编码集用的不是UTF8，如果修改可以按照linux修改mysql编码集的方式进行修改，但是mysql镜像制作者应该考虑到这个问题。

 

5.查看官方文档

 

 可以看到官方有默认启动是u8的语法，如下：(指定root的密码是123456，指定创建的数据库实例是ssm，向外部暴露端口是3306。并且指定编码集。)

docker run --name mysql-ssm -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=ssm -d -p 3306:3306 hub.c.163.com/library/mysql --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci 

接下来进入到容器之后查看mysql状态：

复制代码
docker@default:~$ docker exec -it 4f bash #进入容器
root@4fb26410b8b8:/# mysql -uroot -p #登录mysql
Enter password:

6.重启上面ssm镜像并且浏览器访问服务

复制代码
docker@default:~$ docker ps -a
CONTAINER ID        IMAGE                         COMMAND                  CREATED              STATUS              PORTS                    NAMES

复制代码

浏览器访问：(可以正常登录，并且数据库也正常，可以插入中文)

 

2.上面的SSM镜像发布到阿里云镜像仓库

1.登录阿里云创建仓库 

 2.命令行操作推送到仓库

1.登录阿里云 Docker Registry

docker@default:~$ docker login --username={username} registry.cn-hangzhou.aliyuncs.com
Password:
WARNING! Your password will be stored unencrypted in /home/docker/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

用于登录的用户名为阿里云账号全名，密码为开通服务时设置的密码。

 

2.将镜像推送到Registry

(1)给镜像打tag

sudo docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/qlq_repository/ssm_tomcat:[镜像版本号]

例如：

docker tag fbc765e38da8 registry.cn-hangzhou.aliyuncs.com/qlq_repository/ssm_tomcat:latest

 

(2)推送到阿里云仓库

docker push registry.cn-hangzhou.aliyuncs.com/qlq_repository/ssm_tomcat:[镜像版本号]

例如：

复制代码
docker@default:~$ docker push registry.cn-hangzhou.aliyuncs.com/qlq_repository/ssm_tomcat:latest
The push refers to repository [registry.cn-hangzhou.aliyuncs.com/qlq_repository/ssm_tomcat]
2a0a100e3652: Pushed
f79699072473: Pushed
8cb01d738d7e: Pushed

复制代码

 

3.从阿里云镜像仓库查看版本信息：

补充： 用utf8mb4编码集建的数据库报错 Specified key was too long; max key length is 767 bytes， 解决采用数据库编码集采用utf8、数据库校对规则采用utf8_general_ci。如下：

docker run --name mysql-ssm -e MYSQL_ROOT_PASSWORD=123456 -e MYSQL_DATABASE=rtecm -d -p 3306:3306 hub.c.163.com/library/mysql --character-set-server=utf8 --collation-server=utf8_general_ci

 

补充：拉取oracle镜像 

(1)在https://c.163.com/hub#/library/search?keyword=oracle上面搜索oracle相关镜像，或者直接docker search搜索镜像。我习惯在网上搜索。

 (2)拉取该镜像

docker pull hub.c.163.com/springwen/oracle-xe-11g:latest

(3)运行该镜像

docker run -d -p 1521:1521 hub.c.163.com/springwen/oracle-xe-11g:latest

(4)接下来进入该容器sqlplus链接查看，账户信息系如下：
