Seems to be a premission issue. Does anyone know how to fix this error.

The issue is a Prometheus issue with UserID permissions. I found the solution in the Prometheus community.

@lehatdst do you have a reference for that?

I found the link: https://github.com/prometheus/prometheus/issues/5976 which had suggestion on the issue. I used the "--user root" on the sudo docker command when I start prometheus. It appears to work, until a different solution is tested. This works for starting PROMETHEUS: sudo docker run --user root -d -p 9090:9090 --name=prometheus -v /tmp/prometheus-pure.yml:/etc/prometheus/prometheus.yml -v /tmp/prometheus-data:/prometheus prom/prometheus:latest
