pull access denied for mypostgres, repository does not exist or may require 'docker login' : how to name 'mypostgres' – Ubuntu

I have Ubuntu 22.04 and run next command:

docker run -d mypostgres -e POSTGRES_PASSWORD=1111 postgres -c shared_buffers=256MB -c max_connections=200

and I got following answer:

Unable to find image ‘mypostgres:latest’ locally
docker: Error response from daemon: pull access denied for mypostgres, repository does not exist or may require ‘docker login’: denied: requested access to the resource is denied.

So what is the correct name for ‘mypostgres’?
Can I write here the occasional name that I want?

    You should use postgres instead if you want to download the image from dockerhub. If you want specific version you can use tags provided on the dockerhub page ie. postgres:14.5

    What you are missing here is --name switch before mypostgres You can use --name switch to name your container

    Full command:

    docker run -d --name mypostgres -e POSTGRES_PASSWORD=1111 postgres -c shared_buffers=256MB -c max_connections=200

    –name before mypostgres , because docker understood that you want an image called mypostgres not a postgres images. and didn’t find an official image with that name.
