i've got a kubernetes node, control-plane, which is untainted for deploying pods to. i've got a docker image sdmay23-42.ece.iastate.edu:5000/canvas-lti-frontend:v2 .
i'm signed into docker cli. the daemon.json is set with insecure registry and i can verify with docker info :

Docker Root Dir: /var/lib/docker
 Debug Mode: false
 Username: sdmay2342
 Registry: https://index.docker.io/v1/
 Labels:
 Experimental: false
 Insecure Registries:
  sdmay23-42.ece.iastate.edu:5000
  127.0.0.0/8
 Live Restore Enabled: false

i can pull the image:

Status: Image is up to date for sdmay23-42.ece.iastate.edu:5000/canvas-lti-frontend:v2
sdmay23-42.ece.iastate.edu:5000/canvas-lti-frontend:v2

i can build a container from the image:

CONTAINER ID   IMAGE                                                    COMMAND                  CREATED         STATUS          PORTS                                       NAMES
ad582a4d514b   sdmay23-42.ece.iastate.edu:5000/canvas-lti-frontend:v2   "docker-entrypoint.s…"   6 seconds ago   Up 6 seconds    3000/tcp                                    test-frontend

when i deploy it to the node from yaml manifest, i get an error. basic manifest:
