Docker image from private Docker Hub

Hello, I created a Docker image following the guide, and uploaded it to a private Docker Hub registry account. When I try to send a script via spark-submit, I get an error with the following message. If I try a public image I don't get this problem, so I guess I need to enter my login information somewhere. Is it possible to do this? Or do I need to upload my images somewhere else?   Application report for application_1640081147608_3034 (state: FAILED)   21/12/22 14:22:32 INFO Client:          client token: N/A          diagnostics: Application application_1640081147608_3034 failed 1 times (global limit =2; local limit is =1) due to AM Container for appattempt_1640081147608_3034_000001 exited   with  exitCode: 7   Failing this attempt.Diagnostics: [2021-12-22 14:22:26.758]Exception from container-launch.   Container id: container_e5006_1640081147608_3034_01_000001   Exit code: 7   Exception message: Launch container failed   Shell error output: image: registry.hub.docker.com/flucio/gedap is not trusted.   Disable mount volume for untrusted image   image: registry.hub.docker.com/flucio/gedap is not trusted.   Disable mount volume for untrusted image   image: registry.hub.docker.com/flucio/gedap is not trusted.   Disable cap-add for untrusted image   Docker capability disabled for untrusted image   Unable to find image 'registry.hub.docker.com/flucio/gedap:latest' locally   /usr/bin/docker: Error response from daemon: pull access denied for registry.hub.docker.com/flucio/gedap, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.   See '/usr/bin/docker run --help'.   Shell output: main : command provided 4   main : run as user is luciof   main : requested yarn user is luciof   Creating script paths...   Creating local dirs...   Getting exit code file...   Changing effective user to root...   Wrote the exit code 7 to /data3/hadoop/yarn/local/nmPrivate/application_1640081147608_3034/container_e5006_1640081147608_3034_01_000001   /container_e5006_1640081147608_3034_01_000001.pid.exitcode       [2021-12-22 14:22:26.780]Container exited with a non-zero exit code 7.   [2021-12-22 14:22:26.782]Container exited with a non-zero exit code 7.   For more detailed output, check the application tracking page: https://epod-master2.vgt.vito.be:8090/cluster/app/application_1640081147608_3034 Then click on links to logs of each attempt..
