Buildout is a pretty useful tool, but the documentation is somewhat lacking. I needed to have specialized buildouts for dev and staging that extend a more general buildout. I couldn’t find this in the buildout docs, but I found it here.
In my case, I needed a buildout for staging that omits software that we already have installed via RPMs. Luckily it’s possible:
$ cat staging.cfg [buildout] extends = buildout.cfg eggs -= pyodbc==2.1.8 psycopg2==2.4 coverage>=3.4
As you might guess,
= also work and do what you’d expect.
