I think I've got this working, but I just want to confirm I'm doing this
correctly or if there's a better way to do this.
Basic premise is, want to be able to compile ( once ), then parallel the
push/install. Also want to use roles to be able to selectively decide
which environment to push to at runtime.
Also, is there a better way to test directory existence that I'm
missing?
Would be run with something like:
fab deploy:1.73 -roles prd
from __future__ import with_statement
from fabric.api import *
from fabric.contrib.console import confirm
env.roledefs = {
'prd' : ['host1','host2'],
'qa' : ['qahost1','qahost2'],
'dev' : ['devhost1']
}
def _package():
# eventually will be a compile, but testing with tar.
local("tar -cvf %s.tar %s" % (env.tarball, env.codedir))
@parallel
def _push():
# smarter way to test directory existence?
with settings(warn_only=True):
result = run("ls /opt/ldad/proserv")
if result.failed and not confirm("Directory does not exist.
Continue?"):
abort("Aborting at user request")
put(env.tarball, "/opt/ldad/proserv")
@task
@runs_once
def deploy(ver):
env.pkgver = ver
env.workdir = "/Users/steve/work/ldadscript"
env.codedir = "%s/LdadIntegration-%s" % (env.workdir, env.pkgver)
env.tarball = "%s.tar" % (env.codedir)
_package()
execute(_push)
