迁移应用场景

1.迁移部分项目到新的仓库地址

2.迁移组以及子组下所有的项目

3.迁移所有gitlab组

要求

1.基本要求

a 新的git地址和老的git地址都有对应的权限token

b 脚本服务器和老的git服务器以及新的git服务器网络通的（ssh方式拉取代码）

c 配置ssh拉取代码（新旧gitlab，可选择https方式）

0.配置ssh方式拉取代码

步骤一：生成SSH密钥

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"   //换成自己的邮箱

1. 生成成功后，你将在终端或Git Bash中看到一条消息，其中包含公钥的位置，默认为~/.ssh/id_rsa.pub。

步骤二：将SSH公钥添加到GitLab账户

1. 复制SSH公钥的内容。你可以使用以下命令将其打印到终端或Git Bash中：
2. cat ~/.ssh/id_rsa.pub

1.获取项目token

配置添加token（有读写api的相关权限）

将token进行记录

2.迁移组

选择要迁移的组

setting—–>General—->Advanced——->Export group (导出组文件)

再按创健组的顺序在新的进行导入即可

3.迁移组下所有项目（包括子组下的所有项目）

通过python脚本迁移所有仓库代码

注： 请将对应的token修改，git地址修改

import requests
import os
import subprocess


ACCESS_TOKEN = "*****************"  //迁移token老的git地址token


GITLAB_API_URL = "https://*.*.*.*/api/v4"  //gitlab  api地址

def clone_repo(ssh_url, path):
    if not os.path.exists(path):
        os.makedirs(path)
    print(ssh_url,path)
    subprocess.call(["git", "clone", "--mirror", ssh_url, path])

def push_repo(ssh_url, path):
    new_repo_url = ssh_url.replace("gitlab.fosun.com", "gitlab.assistfc.com")
    os.chdir(path)
    subprocess.call(["git", "remote", "set-url", "--push", "origin", new_repo_url])
    subprocess.call(["git", "push", "--mirror"])
    print("push --mirror new_repo_url %s"%new_repo_url)


def get_subgroups_and_projects(group_id, base_path):
    projects = []
    groups_to_check = [(group_id, base_path)]

    while groups_to_check:
        current_group_id, current_path = groups_to_check.pop(0)

        subgroup_response = requests.get(
            f"{GITLAB_API_URL}/groups/{current_group_id}/subgroups",
            headers={"PRIVATE-TOKEN": ACCESS_TOKEN}
        )
        if subgroup_response.status_code == 200:
            subgroups = subgroup_response.json()
            for subgroup in subgroups:
                subgroup_path = os.path.join(current_path, subgroup['path'])
                groups_to_check.append((subgroup['id'], subgroup_path))

        project_response = requests.get(
            f"{GITLAB_API_URL}/groups/{current_group_id}/projects",
            headers={"PRIVATE-TOKEN": ACCESS_TOKEN}
        )
        if project_response.status_code == 200:
            print("project",project_response)
            for project in project_response.json():
                print("project info",project)
                print("project['path']",project['path'])
                project_path = os.path.join(current_path, project['path'])
                print("project_path",project_path)
                clone_repo(project['ssh_url_to_repo'], project_path)
                push_repo(project['ssh_url_to_repo'], project_path)
                projects.append(project)

    return projects



group_id = ***  //迁移的组id注意修改
base_path = "/tmp/test"   //代码存放目录
projects = get_subgroups_and_projects(group_id, base_path)

执行脚本进行脚本迁移（完成）
