buildbot from start

Question

should be dumb as everybody seems to installed it without trouble. I spent hours within a fresh squeeze and tried different configurations (easy_install, aptitude and from source 0.81p.tar.gz) the best I got is a page from the localhost:9989 without any slave started.

Knowing that I made the 2 accounts : buildmaster and buildslave how to clean and reinstall it to have server and 1 slave for git ?

thanks in advance

Added :

You are right some details are missing:

I use buildbot from virtualBox with a Debian squeeze 6.0 in 32bits The both accounts : buildmaster and buildslave are running within this same Virtual environment.

I just tried the little example (this seems really interesting) : easy_install buildbot buildbot create-master /tmp/experimental_buildmaster buildbot start /tmp/experimental_buildmaster

1. as root the jinja2 was missing whereas from buildmaster there were no complain (??)
2. commented the Git calls that created errors to try to start the simplest demo
3. buildslave create-slave /tmp/experimental_buildslave 127.0.0.1:9989 slave-name mypasswd
4. in the log something appear allways : "No address associated with hostname"

it seems I'm closer with this no ?

Answer 1

for people like kamal this may be usefull :

The little demo works now: - I did all as root with no build accounts. - easy_install buildbot - buildbot create-master /tmp/experimental_buildmaster

most important is here

cp /tmp/experimental_buildmaster/master.cfg.example xperimental_buildmaster/master.cfg edit it 

and pay attention to : slavePortnum default is :9989 and git confs : buildmaster will give errors with bad params

then

buildbot start /tmp/experimental_buildmaster

wait for the "started sucessfully"

easy_install buildbot-slave

buildslave create-slave /tmp/experimental_buildslave localhost:9989 example-slave Password

I strongly disagree with the proposed ".. .. .."

buildslave start /tmp/experimental_buildslave

and now for something completely different : open browser to localhost:8010

the welcome page is here, click buildslave to see your slave: rock'n roll !

If you're having trouble with the configuration, the doc is pretty comprehensive. I only had a few problems with stuff more obscure than the doc can answer, at which point I turned to the nice folks - a number of their developers - on their IRC channel (#buildbot on freenode), who were very helpful.

Some additional information about configuring abd running buildslave after it's creation.

After installing buildbot package int.d script /etc/init.d/buildbot is added to enable running buildbot as a service (starting automatically after system restart and so on).

For this script to run successfully you need to edit conf file for this script. File name is specified inside the script, typically it is /etc/default/buildbot. Options in this file are pretty clear. One interesting thing you can tune here - the user from which buildbot will be running (default is buildbot). Small example of when it is useful:

I had to write a buildbot task, one part of which was managing virtual machines running on builslave machine (starting, stopping, managing snapshots). But rights for doing this had only vbox user (I used Virtual Box VMs). So I simply changed the user field in /etc/buildbot/default to accomplish this.

I hope this information will be useful to you.

Have you looked at the first run tutorial?

• There is no reason to run buildbot as root (and reasons not to, as there have been a few security issues with buildbot). Depending on how you installed buildbot, the jinja2 dependency will be installed in different places. In particular, if you installed it using pip/easy_install not as root, then it is probably installed in your users directory, which root won't access by default.
• The slave will try to figure out its hostname. That might be causing the error you get about no hostname for address.
