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

 

Docker实践2:安装Docker及weblogic镜像_第1张图片

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 status
docker (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 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。

[weblogic@k8s-node-1 dockerfiles]$ sudo sh buildDockerImage.sh -g
Checking if required packages are present and valid...
fmw_12.1.3.0.0_wls.jar: OK

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 .

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 | grep "IPAddress"

 

然后运行http://172.17.0.1:8001/console,进入weblogic管理控制台(weblogic/welcome1)
