使用 CLI 导出和导入仪表板的超级集（用于版本控制）

Question

目标：我的目标是从超集中导出所有仪表板，以便我可以将它们保存为备份，并确保我可以导入它们。

现有设置：我从 git 克隆超集并用于docker-compose -f docker-compose-non-dev.yml up 设置和运行超集（遵循本文档）

问题：使用 superset CLI：我使用此文档 连接到正在运行 superset 的现有 docker 映像，然后运行它，superset export-dashboards但它会引发以下错误：

请帮我调试，我还更改了“VERSIONED_EXPORT”：True

如果您使用 Docker 部署了 Apache Superset，这就是成功导出仪表板的方法。

先决条件：我假设您正确部署了 Superset。这是一个简单的例子

git clone https://github.com/apache/superset.git
cd superset
git checkout 3.0.0
TAG=3.0.0 docker compose -f docker-compose-non-dev.yml up

如果您没有修改部署，您正在运行的服务应如下所示：

docker compose ps

NAME                   IMAGE                                                  SERVICE
superset_app           apachesuperset.docker.scarf.sh/apache/superset:3.0.0   superset
superset_cache         redis:7                                                redis
superset_db            postgres:14                                            db
superset_worker        apachesuperset.docker.scarf.sh/apache/superset:3.0.0   superset-worker
superset_worker_beat   apachesuperset.docker.scarf.sh/apache/superset:3.0.0   superset-worker-beat

superset_app容器的服务名称是superset。

出口

创建导出 zip：

docker compose exec superset superset export-dashboards

查找导出 zip 的文件名dashboard_export_20230922T132800.zip：

docker compose exec superset ls -l

-rw-r--r-- 1 root     root     238373 Sep 22 13:28 dashboard_export_20230922T132800.zip

将导出 zip 从容器复制到您的主机：

docker compose cp superset:/app/dashboard_export_20230922T132800.zip .
