HOWTO Re-Enact Inception with Vagrant and LXC

martinkenny — 2013-06-08T17:40:00+00:00

This is an update to an item originally published on Wednesday, May 29th 2013.After fooling around with Vagrant and LXC for a few days (thanks to Fabio Rehm’s awesome plug-in) , I decided to pull everything together into a working, reproducible setup that allows me to develop and test on four different Linux distributions, as well as prepare Puppet scripts for production deployments — and all without the hassle of running multiple VirtualBox instances. By using LXC inside one “host” VM, this setup uses far less resources — and with a few tweaks, it also lets me access my Mac’s file system from both inside the parent VM and from the Vagrant environments running as containers inside that VM: In a nutshell, the advantages are: Run everything on a single VM — as many different Linux distros as you want Run multiple machines simultaneously with nearly zero overhead Significantly less clutter on your hard disk (boxes stay inside the VM) No need to install Vagrant directly on your Mac Your Mac’s filesystem is transparently mounted inside each environment with zero hassle Assuming you have VirtualBox set up already, here’s how to go about reproducing this: Set up a suitable “parasite” host The first step is to set up an Ubuntu 64-bit VM with an extra host-only network interface: This uses VirtualBox’s built-in DHCP server and will be the interface through which you’ll connect to the VM. The reason I prefer setting up a second interface is that I’d rather use this than fool around with port mapping in the default interface (which I use to NAT out of my laptop), and it mirrors around 99% of my production setups (i.e., a dedicated network interface for management) Now grab the Ubuntu 12.04.2 server ISO and do a bare minimum install, setting the host name to something like containers and skipping everything else — i.e., Choose only OpenSSH Server near the end). (For the purposes of this HOWTO, I’m going to assume you created a local user called… user — replace as applicable) I recommend that you don’t set up LVM (it’s somewhat pointless in a VM, really), don’t mess with the defaults and go with LTS rather than bleeding edge here — I had to trash a similar 13.04 install already after a kernel update. Finally, after you’re done Required Packages Once you’re done installing, it’s package setup time: sudo apt-get update sudo apt-get dist-upgrade # grab the basics we need to get stuff done sudo apt-get install vim tmux htop ufw denyhosts build-essential # grab vagrant-lxc dependencies sudo apt-get install lxc redir # the easy way to ssh in sudo apt-get install avahi-daemon Once that’s done, install the VirtualBox Guest Extensions in the usual way (i.e., use the relevant menu option to mount the CD image, run the installer as root, reboot the VM, etc.) Networking tweaks Now for a few networking changes that make it simpler (and faster) to access your new VM. First off, disable DNS reverse lookups in sshd by adding the following line to /etc/ssh/sshd_config (they’re pointless in a local VM and cause unnecessary connection delay): UseDNS=no Then set up eth1 by editing /etc/network/interfaces to look like so: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet dhcp The Easy Way In Now we’ll set up avahi so that your VM announces its SSH service to your Mac using Bonjour — to do that, create /etc/avahi/services/ssh.service and toss in this bit of XML: %h _ssh._tcp 22 To get avahi to start in a headless machine, you need to disable dbus support in /etc/avahi/avahi-daemon.conf — which, incidentally, is also the right place to ensure Bonjour advertisements only go out via eth1. So you need to add these two lines to that file: allow-interfaces=eth1 enable-dbus=no Now you’re ready to enable the network interface: sudo ifup eth1 sudo service avahi restart If you use ufw, you must open all traffic to lxcbr0: sudo ufw allow in on lxcbr0 sudo ufw allow out on lxcbr0 …and change DEFAULT_FORWARD_POLICY to "ACCEPT" in /etc/default/ufw - otherwise your host system won’t be able to talk to your containers, and they won’t be able to reach the outside. The First Neat Bit You now have a nice, clean way to login to the machine — you can always connect via ssh containers.local, regardless of which address VirtualBox’s DHCP server grants the VM, and in case you ever have to put the VM on a LAN to work from another machine, you can bridge eth1 and things will just work™. Housekeeping If you’re going to be using the VM for development alone, it’s rather convenient to set up password-less sudo by tweaking /etc/sudoers to read: %sudo ALL=(ALL:ALL) NOPASSWD: ALL Also, and since we’re going to rely on VirtualBox’s shared folders, we need to change the vboxsf group’s GID to 1000 and add your user (user in this example) to it in /etc/group: vboxsf:x:1000:user This is key to getting shared folders working nicely with Vagrant, because VirtualBox adds the vboxsf as the next available GID on the VM (which is 1001 under Ubuntu on a fresh install) but the vagrant UID/GID is typically 1000 (since it’s the first user created in a guest system). So you need to make sure these match, or else you’ll have all sorts of problems with file permissions on shared filesystems. You should also tweak /etc/hosts and /etc/hostname accordingly: $ cat /etc/hosts | head -2 127.0.0.1 localhost 127.0.1.1 containers.yourdomain.com containers $ cat /etc/hostname containers …and, finally, placing your SSH key into the user‘s authorized_keys file (manually, since the Mac, alas, doesn’t ship with ssh-copy-id: me@mac:~$ cat ~/.ssh/id_rsa.pub | pbcopy me@mac:~$ ssh containers.local Password: Last login: Tue May 28 17:28:32 2013 from 192.168.56.1 user@containers:~$ mkdir .ssh; tee .ssh/authorized_keys # Cmd+V - Ctrl+D user@containers:~$ chmod 400 .ssh/* Installing Vagrant with LXC support After this is done, you should be able to fire up your VM and SSH to it by typing: ssh containers.local And be magically there. So now you can install Vagrant and Fabio Rehm’s awesome plug-in by doing something like: wget http://files.vagrantup.com/packages/7e400d00a3c5a0fdf2809c8b5001a035415a607b/vagrant_1.2.2_x86_64.deb sudo dpkg -i vagrant_1.2.2_x86_64.deb vagrant plugin install vagrant-lxc …which is all you need to get started. To get suitable boxes and start working, check out the plug-in README. The Second Neat Bit Now set up a VirtualBox shared folder pointing to your home directory — it will show up as a /media/sf_username mount inside the VM. The really neat bit is that if you cd into that, set up a Vagrantfile, do a vagrant up --provider=lxc and then vagrant ssh into the LXC container, you’ll be able to access your Mac’s file system via /vagrant from inside the container. Wrap your head around that for a second — you can develop on your Mac and test your code on a set of different Linux environments without ferrying copies across. And, of course, you can use Puppet to provision those environments automatically for you. Port Forwarding Finally, a small fix - to be able to access forwarded ports from your containers on version 0.3.4 of the plug-in, you need to tweak it a bit: cd ~/.vagrant.d/gems/gems/vagrant-lxc-0.3.4/lib/vagrant-lxc/action vi forward_ports.rb # now edit the redirect_port function to remove the 127.0.0.1 binding like so: def redirect_port(host, guest) #redir_cmd = "sudo redir --laddr=127.0.0.1 --lport=#{host} --cport=#{guest} --caddr=#{@container_ip} 2>/dev/null" redir_cmd = "sudo redir --lport=#{host} --cport=#{guest} --caddr=#{@container_ip} 2>/dev/null" @logger.debug "Forwarding port with `#{redir_cmd}`" spawn redir_cmd end Here Be Dragons Another thing I’m experimenting with is using btrfs - Ubuntu 13.04 ships with a version of LXC that is btrfs-aware and significantly further reduces the amount of disk space required (lxc-clone actually performs a filesystem snapshot, which is terrific), but that’s a bit beyond the scope of this piece. Setting up Ubuntu with btrfs If you want to try that, here’s a short list of the steps I’ve followed so far: Create a new VirtualBox VM with 512MB or RAM, two network interfaces (as above) and three separate VDI volumes: 2GB for / 512MB for swap 8GB for /var Install from the Ubuntu 13.04 Server ISO Set up the partitions using btrfs for both data volumes (/ and /var), with noatime set (that’s about the only useful flag you can set inside the installer) Once the partitioner sets up your volumes, switch to a new console and remount them with: mount -o remount,compress=lzo /target mount -o remount,compress=lzo /target/var Once you’ve installed the system and before rebooting, go back to the alternate console and edit /etc/fstab to have noatime,ssd,compress=lzo,space_cache,autodefrag as options to (you can use compress-force=lzo if you want everything to be compressed). To get rid of the “Sparse file not allowed” message upon booting, comment out the following line in /etc/grub.d/00_header and run update-grub: if [ -n "\${have_grubenv}" ]; then if [ -z "\${boot_once}" ]; then save_env \ recordfail; fi; fi Proceed as above, and hike up the RAM on the VM to your liking. If all goes well, you’ll have a much smaller VM footprint due to the use of lzo compression, a relatively small swapfile and copy-on-write support. There are only three caveats: You need to do this for the moment (should be fixed in updated boxes after 0.3.4) The VM will be a little more CPU-intensive when doing disk-intensive tasks (I find it a sensible trade-off) The usual tricks for shrinking VDI files no longer apply to btrfs volumes (so far even GParted Live hasn’t really worked for me), so it’s probably best to save a copy of the VM somewhere. ☯ "HOWTO Re-Enact Inception with Vagrant and LXC" was written by Rui Carmo for The Tao of Mac and was originally posted on Wednesday, May 29th 2013.

Operational Transforms And Core Data, In The Wild

martinkenny — 2013-05-31T15:09:00+00:00

I love this. Milen Dzhumerov of Clear walks through their clever use of operational transforms to sync changes to a Core Data database over iCloud: It should be noted that the system described above is probabilistic, stemming from the distributed nature of iCloud – a peer only ever has a local snapshot of the global state. For example, a device cannot know whether there is some other device that has not synced yet or whether a device has gone offline forever. Consequently, all algorithms employed must be designed to take these scenarios into account. In Clear, the system handles any such cases by simply never losing data – i.e., taking a union defined on the object graph. In very rare cases, it might end up with the undesirable behaviour of a deleted object re-appearing but that is preferable to losing data. Back at CocoaConf San Jose, Kevin Kim and I were talking about doing this exact thing—recording and playing back transforms to the Core Data object graph and sending those individual transactions over the wire (iCloud in this case). It’s the same way that Google Wave worked. I miss Wave. :( I’m curious how this technique holds up across different model versions. One of the biggest drawbacks to treating Core Data as an object storage and syncing framework is what to do when two apps of different versions try to access the same store. If models could be migrated through these operational transforms, but done in a backward compatible way, then older clients wouldn’t have to break. But now we’re glossing over the specific data architecture decisions that affect this resiliency. I like Clear’s approach overall, but I suspect that mixing object persistence and data syncing is not a very good general purpose solution. You’d have to craft your app around the limitations, like Clear did. (via Drew McCormack) ✦ Permalink
