This is a little trick I use to spin up the packages instalation on Debian/Ubuntu boxes in Vagrant.
I add a simple function that checks if a directory named something similar to ~/.vagrant.d/cache/apt/opscode-ubuntu-12.04/partial
(it may have another path in Windows or MacOS) and create the directory if it doesn't already exist.
def local_cache(box_name)
cache_dir = File.join(File.expand_path(Vagrant::Environment::DEFAULT_HOME),
'cache',
'apt',
box_name)
Locate the section for your github remote in the .git/config
file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = [email protected]:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
# SSL self signed localhost for rails start to finish, no red warnings. | |
# 1) Create your private key (any password will do, we remove it below) | |
$ openssl genrsa -des3 -out server.orig.key 2048 | |
# 2) Remove the password | |
$ openssl rsa -in server.orig.key -out server.key |
This playbook has been removed as it is now very outdated. |
