Docker实践2:安装Docker及weblogic镜像
安装Docker
以root登录，运行
vi /etc/yum.repos.d/public-yum-ol6.repo,添加如下段落
[ol6_addons]
name=Oracle Linux $releasever Add ons ($basearch)
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/addons/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1
运行yum install docker
在运行过程中因为网络缓慢，可能出现退出情况，再运行一遍，如果遇到yum提示
another app is currently holding the yum lock;waiting for it to exit
可能是系统自动升级正在运行，yum在锁定状态中。
可以通过强制关掉yum进程：
#rm -f /var/run/yum.pid
完成后运行service start docker.
# chkconfig docker on
# service docker statusdocker (pid 9044) is running...
添加能直接运行docker权限的用户
# groupadd docker
# service docker restart
# usermod -a -G docker <your_user>
将git构建代码拿到本地
#yum install git
切换回weblogic用户，运行
$ git clone https://github.com/oracle/docker.git
如果网络比较慢的话再来一遍。
Build jre8
docker build -t oracle/serverjre:8 .
|
[weblogic@k8s-node-1 java-8]$ sudo docker build -t oracle/serverjre:8 . |
Build WebLogic Generic
进入../docker/OracleWebLogic/dockerfiles/12.1.3目录
下载相应的文件包括server-jre-8u73-linux-x64.tar.gz,fmw_12.1.3.0.0_wls.jar,wls1213_dev_update3.zip放入
通过xmanager的xftp.
运行$ sudo sh buildDockerImage.sh -g
-d主要采用_dev的包，构件开发环境。
-g采用generic的包，也就是fmw_12.1.3.0.0_wls.jar包，构建生产环境。

如果sudo出错，解决办法：
以root用户修改/etc/sudoer 文件属性为root可修改，并在root ALL 行下添加 weblogic ALL（类似root行）
# chmod u+w sudoers
# vi sudoers
添加 weblogic ALL=（ALL） ALL
通过docker images查看本地的镜像
建立一个空域的weblogic container
进入sample目录下1213-domain目录,修改脚本,让上面的域基于generic来构件,然后运行
docker build -t 1213-domain . 或者是
sudo docker build -t 1213-domain --build-arg ADMIN_PASSWORD=welcome1 .
|
[weblogic@k8s-node-1 1213-domain]$ sudo docker build -t 1213-domain --build-arg ADMIN_PASSWORD=welcome1 . Initializing WebLogic Scripting Tool (WLST) ... Welcome to WebLogic Server Administration Scripting Shell Type help() for help on available commands domain_name : [base_domain]
---> d35626c7b868 |
运行容器
docker run -d 1213-domain
因为当前启动命令为startWebLogic.sh,所以通过logs可以看到weblogic启动日志.
此外还有另外两种启动方式:
docker run -d --name wlsadmin --hostname wlsadmin -p 8001:8001 1213-domain
docker run -d -p 8001:8001 --name=wlsadmin 1213-domain startWebLogic.sh
docker logs $container id
docker inspect <container_id> | grep "IPAddress"
然后运行http://172.17.0.1:8001/console,进入weblogic管理控制台(weblogic/welcome1)
修改容器,部署一个helloworld的应用,修改完commit
| sudo docker commit -m "Added HelloWorld Application" -a "Eric Nie" 1a4f7376802f823ce71015a232b85810db17eec38ed54670d1ca06fb4f0e750e 1213-helloworld:v1 |
