Docker Container Backup/Restore

備份正在運行 Docker Container 的語法: docker export <CONTAINER_ID|NAME> > <CONTAINER_ID|NAME>-backup.tar

docker export CentOS6 > /backup/CentOS6-backup.tar

還原已備份的 Docker Container 的語法 : docker import - <USERID/CONTAINER_ID|NAME>-backup < <CONTAINER_ID|NAME>-backup.tar

docker import - tryweb/centos6-backup < /backup/CentOS6-backup.tar
docker images | grep centos6-backup
docker run -i -t --name="CentOS6-01" tryweb/centos6-backup /bin/bash

可以定期自動備份

export NOWDT=`date +%F_%T`
docker export CentOS6 > /backup/CentOS6-backup-$NOWDT.tar
rm -f /backup/CentOS6-backup.tar
ln -s /backup/CentOS6-backup-$NOWDT.tar /backup/CentOS6-backup.tar

定期復原驗證

docker stop CentOS6-01
docker rm CentOS6-01
docker rmi tryweb/centos6-backup
docker import - tryweb/centos6-backup < /backup/CentOS6-backup.tar
docker run -i -t --name="CentOS6-01" tryweb/centos6-backup /bin/bash
