Update Snipe-IT running on Docker container

[mirktmirkt]

Hello,

I am new to Snipe-IT (and Docker:)). Just updated Snipe-IT v6.0.14 to v6.1.0 Docker installation as documented here:
https://snipe-it.readme.io/docs/docker

Is everything OK with this step?

After that, you may need to run migrations using docker run snipeit php artisan migrate.

If I run
# docker run snipeit php artisan migrate
as documented I get:
Unable to find image 'snipeit:latest' locally
docker: Error response from daemon: pull access denied for snipeit, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.

So I just executed this command:
# docker exec -it snipeit php artisan migrate

What am I doing wrong? Or is there a mistake in documentation?

Regards,
mirkt
