The problem and solution of using docker storage and causing Exit to cause files to fail to upload to the server

1. Problem description

The storage installed in the docker container has been in the exit state, resulting in the inability to store files.

2. Solution

View the containers installed in Docker

docker ps -a

Try starting the container

docker start storage (or docker start "container ID")

If the container is still in the exited state after trying to start it, delete the container

docker container rm storage (or docker container rm "container ID")

Enter the /var/fdfs folder and delete the storage file

cd /var/fdfs
sodo rm -r storage

Reinstall the storage container

sudo docker run -dti --network=host --name storage -e TRACKER_SERVER=10.0.2.15(intranet ip):22122 -v /var/fdfs/storage:/var/fdfs delron/fastdfs storage

Check whether the container is started successfully

3. Test whether the container can be used normally

Note: To test in Python's Django module, you need to install the fdfs_client module

pip3 install fdfs_client

Enter the Django shell environment

python manage.py shell

Write in the shell environment

from fdfs_client.client import Fdfs_client

# client.conf is the configuration file fdfs = Fdfs_client('utils/fastdfs/client.conf')

# Upload the file by file name fdfs.upload_by_filename('media/2018.png')

Get the response back

Test whether the path is successful
