Docker实战：部署JAR应用并连接数据库，集成Jira服务

mkdir /home/bak_jira/
cd /home/bak_jira/
# 将备份文件拷贝到宿主机内,这里的路径仅供参考，实际路径请拷贝自己页面中的备份文件输出路径
# 拷贝命令 docker cp <容器名>:<文件完整路径> <宿主机路径>
docker cp jira:/var/atlassian/jira/export/jira.bak.zip /home/bak_jira

# 将头像喝附件也拷贝出来，备份文件是不含附件和用户头像的，需要单独拷贝
# attachments是附件文件夹，avatars是用户头像文件夹
docker cp jira:/var/atlassian/jira/data/ /home/bak_jira
# 拷贝出来之后对其进行打包
cd /home/bak_jira/
tar -zcvf attachments.tar.gz attachments/
tar -zcvf avatars.tar.gz avatars/

# 打包命令 docker commit <容器名> <新镜像名>
docker commit jira bak_jira

# 查看新的镜像是否创建成功
docker images

# 将新的镜像打包成tar压缩包
# 压缩命令 docker save -o <压缩包名称> <镜像名称>
docker save -o bak_jira.tar bak_jira

#将所有的压缩包传到B服务器,这里的方法比较多,可以使用sz命令或scp命令
scp /home/bak_jira/bak_jira.tar root@192.168.1.3:/home/
scp /home/bak_jira/jira.bak.zip root@192.168.1.3:/home/
scp /home/bak_jira/attachments.tar.gz root@192.168.1.3:/home
scp /home/bak_jira/avatars.tar.gz root@192.168.1.3:/home

# cd到压缩文件目录，我这里是/home
cd /home

# 加载镜像命令 docker load -i <压缩包名称>
docker load -i bak_jira.tar

# 查看镜像是否加载成功
docker images

# 此时镜像已经拉进来了，但是启动还需要数据库，这里要尽量保持与原数据库一致，比如jira连接的用户如果是非root用户的话需要在新的数据库中也创建一样的数据库用户并赋予权限。这里请参考上面的链接里面有详细安装步骤

# 接下来启动镜像
docker run -d --name jira  --restart always -p 18009:8080   -e TZ="Asia/Shanghai"   -m 4096M   -v /home/data/jira:/var/atlassian/jira bak_jira
# 参数接释:
# -d 后台运行
# --name 容器名称
# --restart 自启动
# -p 宿主机映射容器内端口,18009是宿主机端口,8080是容器内的服务端口
# -e 时区
# -m 给JIRA分配的最大内存，根据自己的机器配置来，一般2G就够
# -v 将容器内的/var/atlassian/jira文件夹挂载到宿主机的/home/data/jira 方便修改配置文件以及查看日志

# 由于我这里挂载了文件夹，所以直接把压缩包mv到宿主机的/home/data/jira/import即可
mv jira.bak.zip /home/data/jira/import
# 没有挂载也可以使用拷贝命令将备份文件打到容器内的import文件夹，这里的import文件夹路径仅供参考
docker cp jira.bak.zip jira:/var/atlassian/jira/import

# 不知道import文件夹的位置可以使用下面的方法，进入容器内部找
docker exec -it jira bash

# 进入到jira容器中查看server.xml
docker exec -it jira bash
cd /opt/atlassian/jira/conf/
cat server.xml
# 复制打印的内容，exit到宿主机中使用vim命令创建server.xml文件并粘贴刚刚复制的内容，进行修改
