bad59cd04f34 add README

parents:
diff changeset
45 To understand the configuration, first a few notes about the
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
46 architecture of TreePackager. The TreePackager consist of one program
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
47 that periodically updates svn working directories and if something has
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
48 changed, builds a new debian package from the working directory. The
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
49 program should run as a normal user. The sample configuration assumes
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
50 that it's the user "builder" with a home directory "/home/builder". The
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
51 default configuration manages a directory tree under
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
52 "/home/builder/enterprise".
bad59cd04f34 add README

parents:
diff changeset
53
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:

54 The binary packages are built with pbuilder. Because pbuilder uses a
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
55 chroot environment to build the packages, it must be run as root. The
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
56 tree packager therefore needs a way to run pbuilder as root even though
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
57 itself runs as a non-root user. By default the tree packager uses sudo,
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
58 so you have to setup sudo to allow the tree packager user to invoke
bad59cd04f34 add README
Bernhard Herzog <bh@intevation.de>
parents:
diff changeset
59 pbuilder without a password. This can be accomplished with the
bad59cd04f34 add README
