Add documentation for WORDPRESS_DB_HOST

[md5]

This goes with docker-library/wordpress#55

I just noticed there should probably be a comma at the end of this line (after "container"). Should I amend this commit?

LGTM

LGTM, although we'll want to get a PR to the official-images repo open before we push this up 👍

@md5 want the honor of making the PR? It's as easy as cloning both the official-images repo and the wordpress repo somewhere, then running "./generate-stackbrew-library.sh > ../official-images/library/wordpress" and making a PR out of it. 😉

Sure. I was actually playing around with that last night for the Jetty image.

Should it be showing docker-library/wordpress@dc184cf?

It looks like docker-library/wordpress@aac1d2e is the tip of master.

[md5]

It looks like git log -1 -- . doesn't include the merge commit because it didn't touch any files in ..

[md5]

Perhaps git show --format='format:%H' would be appropriate instead of git log -1 --format='format:%H' -- .?

Naw, the commit it's showing is correct. We don't care about the merge commit for the purposes of the official-images repo, since it didn't actually change the contents.
