dkavanagh / create_users.sh

Last active June 7, 2016 12:46

This script creates test users that are the same as created by eucalyptus ui tests. So, if you're setting up a test cloud by some other means (like kickstarting a package-built cloud), you can run this after getting the admin credentials.

	echo "{ \"Statement\": [ { \"Effect\": \"Allow\", \"Action\": \"\", \"Resource\": \"\" } ] }" >all.policy
	k=0
	ADMIN=`cat .euca/euca-admin.ini \|grep "^user" \|awk '{ print $3; }'`
	HOST=`cat .euca/euca-admin.ini \|grep "^default-region" \|awk '{ print $3; }'`
	REGION=$ADMIN@$HOST
	for i in ui-test-acct-00 ui-test-acct-01 ui-test-acct-02 ui-test-acct-03
	do
	echo "creating users for "$i
	euare-accountcreate --region $REGION -a $i

dkavanagh / switchbranch.sh

Created February 5, 2013 20:48

This script is called by passing in a new branch name. It is used by eucalyptus where we have sub-modules that require updating as well as the top level refs. Errors will cause things to stop (like changes not checked in).

	git submodule foreach git checkout $1
	git submodule foreach git pull origin $1
	git checkout $1
	git pull origin $1

dkavanagh / pushtoremote.sh

Last active July 15, 2016 15:28

pushtoremote.sh - I revised this to work with the current branch because I never ended up passing in anything other than that.

	branch=`git rev-parse --abbrev-ref HEAD`
	if [ "$branch" = "master" ] \|\| [ "$branch" = "maint-4.1" ]
	then
	echo "Pushing to "$branch" is no bueno."
	exit -1
	fi
	echo "pushing to "$branch
	git submodule foreach git push origin $branch
	git push origin $branch

dkavanagh / shareimages.sh

Created May 22, 2013 13:03

make all images public (ec2, eucalyptus)

	for i in `euca-describe-images \| awk '{ print $2; }'`
	do
	echo $i
	euca-modify-image-attribute -l -a all $i
	done

dkavanagh / http redirect example

Last active December 18, 2015 09:18

http redirector that works with tornado. start_redirector (in my code) gets called in a background thread.. ignore the callback arg, which is None, but kwargs is passed in containing use_ssl and port as values for the redirect handler.

	def start_redirector(kwargs, callback):
	# can't use tornado for this (not threadsafe). Must use something else, something simpler!
	http_port = 8888
	if eucaconsole.config.has_option('server', 'http.port'):
	http_port = eucaconsole.config.getint('server', 'http.port')
	server = BaseHTTPServer.HTTPServer(('localhost', http_port),
	lambda args: RedirectHandler(kwargs, args))
	server.serve_forever()

	class RedirectHandler(BaseHTTPRequestHandler):
