mongodb的镜像已生成

2.启动mongodb

终端运行以下命令来创建并启动MongoDB容器

docker run -d -p 27017:27017 --name mongodb -v /path/to/gridfs/data:/data/db mongo

/path/to/gridfs/data替换为你想要将GridFS数据文件存储在本地的目录路径。这将会在本地创建一个目录，在其中存储GridFS的数据文件。

关于GridFS数据文件的本地目录路径

确定要存储GridFS数据文件的本地目录路径。例如，假设你想将GridFS数据文件存储在/Users/yourusername/gridfsdata目录 命令行中使用以下命令来启动MongoDB容器并挂载GridFS数据目录

docker run -d -p 27017:27017 --name mongodb -v /Users/lvwei/gridfsdata:/data/db mongo

启动后，设置mongodb容器连接mynet的网络

docker network connect mynet mongodb
docker restart  mongodb

3.工程更改GridFS的配置

Docker容器之间的连接，通常应该使用Docker的服务名称而不是localhost来指定主机名。在这里，应该将MongoDB服务器地址设为Docker容器的名称，即mongodb，而不是localhost。

由 client = MongoClient(‘mongodb://localhost:27017/’)更换为client = MongoClient(‘mongodb://mongodb:27017/’)

4.fastapi工程重新打包镜像,并启动容器

在工程目录下，使用docker build打包，然后停止并删除fastapi容器，然后重新启动fastapi容器。

在http://127.0.0.1:8081/docs#打开后，在网页上选择文件，并上传

6.其它问题

如果使用mongodb://localhost:27017/连接gridFS，则会出现以下异常

raise ServerSelectionTimeoutError(
pymongo.errors.ServerSelectionTimeoutError: localhost:27017: [Errno 111] Connection refused (configured timeouts: socketTimeoutMS: 20000.0ms, connectTimeoutMS: 20000.0ms), Timeout: 30s, Topology Description: ]>

原因：

FastAPI容器连接到MongoDB GridFS容器时，是Docker容器之间的连接，通常应该使用Docker的服务名称而不是localhost来指定主机名。在这里，应该将MongoDB服务器地址设为Docker容器的名称，即mongodb，而不是localhost。
