How are you uploading the file? Where does the error message come from? — Marte Valerio Falcone, Apr 16 '21 at 07:26
Does [this](https://stackoverflow.com/questions/40622162/docker-load-and-save-archive-tar-invalid-tar-header) answer to your question? — Marte Valerio Falcone, Apr 16 '21 at 09:44
Remember that anyone who can reach the Docker socket can pretty trivially root the host; if you're allowing unencrypted connections to the Docker socket on port 2375, that means anyone on your local network can take over your machine. I'd disable the relevant Docker daemon option _immediately_, and use only the Unix socket file to talk to Docker (still speaks HTTP but not over TCP). — David Maze, Apr 16 '21 at 10:23
@DavidMaze then how can I send my files to a container? For my project I need to send some files to the container using docker api. So how can I do it? — Manoj M, Apr 16 '21 at 11:22
@MarteValerioFalcone the error was same, Here i did this via docker api. — Manoj M, Apr 16 '21 at 11:23
Typically you'd run something like an HTTP service in your container, publish its port with a `docker run -p` option, and make an HTTP POST request to the service. Unless you're specifically trying to manage containers, I'd avoid the (high-risk, less-portable) Docker API. — David Maze, Apr 16 '21 at 11:23

seem you need to download manually the specific docker image file then:

// 1- extract file

// 2- then run this command in its folder

// in my case neo4j docker image

use this:

docker load -i .\neo4j

instead of this

docker load -i .\neo4j.7z

// Error processing tar file(exit status 1): archive/tar: invalid tar header
