Where are the files downloaded by Thunder in docker?

With the development of cloud computing and container technology, Docker has become a very popular containerization technology. The wide application of Docker has brought many convenient operations and services, such as using Thunder to download in docker. However, for many users who use docker to download Thunder, they will encounter the problem that the downloaded file cannot be found after the download is completed. Even if the docker cp command is used, the file cannot be copied to the host machine. So, where are the files downloaded by Thunder in docker stored? This article will introduce to you the storage location of Thunder download files in docker.

After using Thunder to download in Docker, we can see that the downloaded file does not appear in the host folder, but the downloaded file can still be seen in the container. This is because in Docker, downloaded files are stored in a directory named "/root/Download" or "/root/downloads" by default. However, this directory is not the directory mounted to the host machine, so we cannot copy the files through the docker cp command.

So, how to get these downloaded files in docker? Among them, one way is to mount through docker volumes. Specifically, when using the docker run command, we can specify a local directory (that is, the mounting directory) through the parameter "-v" to map the files in the container to the host machine, so that we can directly The downloaded file is obtained from the host machine.

For example, if we want to use the Thunder client in the container to download files and store the downloaded files in the download directory under the host's home directory, we can use the following command:

docker run -it -v /Users/username/download:/root/Download  xujinkai/thunder:latest

In this command, "-v /Users/username/download:/root/Download" means that the "/root/Download" directory is mounted in the container to "/Users/username/ in the host machine download" directory, file mapping is implemented.

It is worth mentioning that we need to create the mounting directory in the host in advance, otherwise the error "no such file or directory" will be reported. At the same time, if you want to automatically mount the directory every time you start the container, you can add the following mapping rules in the docker-compose file:

volumes:
  - /Users/username/download:/root/Download

Through the above method, we can quickly obtain the Thunder in the container Downloaded file.

In addition to the above methods, we can also use the docker commit command to package the downloaded file into a new image, and then use the docker save command to export the image to the local to obtain the downloaded file. However, this method requires more steps and is not intuitive enough. Relatively speaking, using docker volumes to mount is simpler and more convenient.

In summary, files downloaded using Thunder in docker are stored in the "/root/Download" or "/root/downloads" directory and will not be mounted on the host machine. If you need to obtain the downloaded file, you can mount it through docker volumes, or you can use the docker commit and docker save commands. I hope this article can help you solve the problem of the storage location of Thunder download files in docker.
