Dockerfile permanent FROM location

[akljsnd123]

Hey All,

I use a dockerfile for aws beanstalk to set new instance
with the following:

FROM million12/nginx-php:latest

The issue is that I use this dockerfile for production environment
and I don’t want to use different versions everytime because of the ‘latest’.
Is it possible to state a certain version instead of latest
and how can I know in beanstalk which version is already being used
in running environment.

Thanks.

For the first question:

docker pull

So

$ docker pull million12/nginx-php
