Harbor升级（从v1.3升级到最新v1.8）

harbor安装

Harbor是k8s常用的私有仓库，属于企业级私有Registry服务器，Harbor提供了更好的性能和安全。提升用户使用Registry构建和运行环境传输镜像的效率。Harbor支持安装在多个Registry节点的镜像资源复制，镜像全部保存在私有Registry中， 确保数据和知识产权在公司内部网络中管控。另外，Harbor也提供了高级的安全特性，诸如用户管理，访问控制和活动审计等，而且Harbor支持中文，方便国人使用。

本文在生产环境的harbor实操，harbor从v1.3版本升级到v1.8。harbor数据库在v1.6版本做了很大的升级。数据库从原来的MySQL升级为postgresql数据库。根据官方文档的解释（https://github.com/goharbor/harbor/blob/master/docs/migration_guide.md），旧版本的harbor升级到最新的v1.8,需先将harbor升级到v1.6,再升级到更高的版本。

准备工作

配置epel源和docker-ce源，安装最新的docker-compse和docker

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum install -y yum-utils
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install docker-compose -y
yum install docker-ce –y
systemctl enable docker
systemctl start docker

下载Harbor1.6和1.8版本的离线安装包

https://storage.googleapis.com/harbor-releases/release-1.6.0/harbor-offline-installer-v1.6.0.tgz

https://storage.googleapis.com/harbor-releases/release-1.6.0/harbor-offline-installer-v1.8.0.tgz

harbor1.3升级到harbor1.6

关闭harbor

cd harbor
docker-compose down

备份harbor以及整个数据库

hharbor1.3安装时，数据库的数据都放在/data/harbor/data里，所以直接备份整个目录即可

mv harbor /backup/harbor

从docker hub拉取1.6和1.8的数据迁移镜像

docker pull goharbor/harbor-migrator:v1.6.0
docker pull goharbor/harbor-migrator:v1.8.0

备份mysql数据库和harbor.cfg到/path/to/backup（安全起见备份mysql的数据库和配置文件）

docker run -it --rm -e DB_USR=root -e DB_PWD=root123 -v /backup/harbor/data/database/:/var/lib/mysql -v /backup/harbor/harbor.cfg:/harbor-migration/harbor-cfg/harbor.cfg -v /path/to/backup:/harbor-migration/backup goharbor/harbor-migrator:v1.6.0 backup

升级数据库框架（将MySQL框架升级为postgresql）

docker run -it --rm -e DB_USR=root -e DB_PWD=root123 -v /backup/harbor/data/database/:/var/lib/mysql -v /backup/harbor/harbor.cfg:/harbor-migration/harbor-cfg/harbor.cfg -v /path/to/backup:/harbor-migration/backup goharbor/harbor-migrator:v1.6.0 up

框架升级后的目录如下图

升级harbor配置文件

docker run -it --rm -v /backup/harbor/harbor.cfg:/harbor-migration/harbor-cfg/harbor.cfg goharbor/harbor-migrator:v1.6.0 --cfg up
将1.6版本的harbor解压到/data目录下
tar zxvf harbor-offline-installer-v1.8.0.tgz -C /data/
cd /data/harbor

复制升级后的数据框架和数据到当前目录

cp -r /backup/harbor/data/ ./
cp /backup/harbor/harbor.cfg ./

新版本的docker-compose.yml需要手动修改，将harbor所需的容器的目录执行到/data/harbor/data下

在当前目录下启动harbor实例

./install.sh

页面访问https://devops.reg.io

没做dns的话可直接访问ip

查看原镜像是否丢失，测试上传下载镜像是否能成功

Harbor1.6升级到harbor1.8

备份harbor1.6

cd /data/
docker-compose down
mv harbor /backup1/

解压harbor1.8到/data/目录下

tar zxvf harbor-offline-installer-v1.8.0.tgz -C /data/

升级harbor.cfg到harbor.yml

docker run -it --rm -v /backup1/harbor/harbor.cfg:/harbor-migration/harbor-cfg/harbor.cfg -v /data/harbor/harbor.yml:/harbor-migration/harbor-cfg-out/harbor.yml goharbor/harbor-migrator:v1.8.0 --cfg up

由于1.8版本的docker-compse已交由harbor.yml控制，在./install.sh时加载harbor.yml文件生成docker-compose.yml（注：数据目录必须使用绝对路径）故还需要对新的harbor.yml进行修改

修改数据目录和日志目录

data_volume: /data/harbor/data
location: /data/harbor/data/log

将数据拷贝到harbor1.8的软件目录下

cp -r /backup1/harbor/data/ /data/harbor/

修改证书期限（10年）

cd /data/harbor/data/cert/
find . -type f | xargs rm –f
$ openssl req -newkey rsa:4096 -nodes -sha256 -keyout ca.key -x509 -days 3650 -out ca.crt
$ openssl req -newkey rsa:4096 -nodes -sha256 -keyout devops-reg.io.key -out devops-reg.io.csr
$ echo 'subjectAltName = DNS: devops-reg.io, IP:192.168.2.112' > extfile.cnf
$ openssl x509 -req -days 3650 -in devops-reg.io.csr -CA ca.crt -CAkey ca.key -CAcreateserial -extfile extfile.cnf -out devops-reg.io.crt
$ openssl x509 -noout -text -in devops-reg.io.crt
启动harbor1.8
cd /data/harbor
./install.sh

登陆https://devops-reg.io（图为升级测试的结果）

完成测试上传下载镜像（注：稳定运行一段时间，将旧版本的备份数据清理！）
