[Blog] Use long options in examples

[ElijahLynn]

Thanks for this write up, I am enjoying going through it!

Since this is a post that is intended to teach may I suggest you use long options instead of short options. This would also save some explaining on what the short options are. It is self documenting to use long options (most of the time).

e.g.

docker run --name db -e MYSQL_ROOT_PASSWORD=123 -p 3306:3306 mysql:latest  

docker run --name db --env=[MYSQL_ROOT_PASSWORD=123] --publish=3306:3306 mysql:latest  

Also, step #3 for the command above discusses the --detach command but it isn't in the example.

I've fixed step #3, for now I've left the short examples but documented the long form below them. This is because it's much more common to see the short values, WDYT?

[ElijahLynn]

That is a happy balance, thanks.

I know it would be a lot of work but adding clarification throughout what the long options are would make it a better teaching tool, not just the one example above.

e.g. docker run -it ubuntu, if it were docker run --interactive --tty it would make more sense.

I am not suggesting to replace that just do what you did in #3 (comment) after the first usage of it and clarify what those options do and/or state the long options.

Good idea, will change this when I get a little time!
