A few places on meta and on the blog advise `git pull` before `./launcher rebuild app`. I’ve never done git pull, only the latter, and my Discourse instance seems to update fine. What’s the value of git pull?

The `git pull` brings down new versions of the `discourse_docker` repo, which is the `launcher` program itself (and all its supporting materials). We do, from time to time, make useful improvements there, although it’s far less frequent (and critical) than updating the application itself.

Also, @sam taught the launcher to update itself in March 2015:

[https://github.com/discourse/discourse\_docker/commit/098533cb0b2bbea0e55ead77f7bc1b8c668965c0](https://github.com/discourse/discourse_docker/commit/098533cb0b2bbea0e55ead77f7bc1b8c668965c0)

So you only need to run `git pull` once if you’re still on an older version, a `./launcher rebuild app` will be sufficient after that.

Is this still true @sam? Even our template reply still says `git pull` in it..

`git pull` is needed if you are on an old version of discourse-docker, that is why I always but it in with my instructions.

No idea if people are running 3 year old versions of discourse docker.

Hmm I think we should drop it at this point, two lines is more better than three.
