cloudfoundry warden安装和配置
warden安装
apt-get install -y linux-image
apt-get install -y build-essential debootstrap
apt-get install -y cgroup-bin
apt-get install -y build-essential debootstrap
apt-get install -y cgroup-bin
gem install bundle
gem sources -a http://ruby.taobao.org/
gem sources --remove http://rubygems.org/
gem install gem-fast
cd warden/warden
bundle
bundle exec rake setup[config/linux.yml]
gem sources -a http://ruby.taobao.org/
gem sources --remove http://rubygems.org/
gem install gem-fast
cd warden/warden
bundle
bundle exec rake setup[config/linux.yml]
在上述配置过程中，rake setup会通过下面的命令在/tmp/warden/rootfs/目录下安装一个基本系统，并作一些简单配置(具体的脚本为root/linux/base/setup.sh)
packages="openssh-server,rsync"suite="precise"mirror=$(grep "^deb" /etc/apt/sources.list | head -n1 | cut -d" " -f2)target="/tmp/warden/rootfs/"$(which debootstrap) --verbose --include $packages $suite $target $mirror
配置容器的默认密码
chroot /tmp/warden/rootfs/passwd设置密码新建vcap用户并设置密码
这两个密码会在create容器的时候用到，也可以用于登陆容器

root@10.254.0.18's password: [此处输入密码]
vcap@10.254.0.18's password: [此处输入密码]
启动warden:
bundle exec rake warden:start[config/linux.yml]
与Warden交互:
bundle exec bin/warden-repl
键入create后就可以创建一个容器了
在创建容器时候可以传入一个grace_time参数，如果不传的话，默认5分钟没有客户连接容器就会自动删除：
If specified, this setting overrides the default time of a container not
being referenced by any client until it is destroyed. The value can
either be the number of seconds as floating point number or integer, or
the `null` value to completely disable the grace time.
