Unable to start UI .. permission denied

[7thstorm]

I installed using the instructions.
When I verify:
$sudo docker pull robmarkcole/deepstack-ui:latest latest: Pulling from robmarkcole/deepstack-ui Digest: sha256:864ea8a9812ca9e917147e75c8d22a0824a2111f3f5c6aa15312c5b3d43607b5 Status: Image is up to date for robmarkcole/deepstack-ui:latest docker.io/robmarkcole/deepstack-ui:latest

However, when I try to run it, I'm getting permission denied

$sudo docker run -p 8501:8501 -e DEEPSTACK_IP='172.16.41.253' -e DEEPSTACK_PORT=777 deepstack-ui Unable to find image 'deepstack-ui:latest' locally docker: Error response from daemon: pull access denied for deepstack-ui, repository does not exist or may require 'docker login': denied: requested access to the resource is denied. See 'docker run --help'.

what am I missing

this is docker question that can be resolved using google, see repository does not exist or may require 'docker login'
