Docker 0.7 is here – welcome RPM distros (and anyone else that lacks AUFS)

The Docker project has continued its mostly-monthly releases with the long anticipated 0.7 release, this time making the storage backend pluggable, so fedora/redhat based users can use it without building a custom kernel.

I’m curious to see the performance differences between the 3 storage backends we have now – but I need to assimilate the wonders of Linking containers for adhoc scaling first.

Try it out – I’m even more convinced that Docker containers have an interesting future :)

Open source Private Cloud SaaS: VDI made simple

Tag: devops,enterprise,new,openstack,saas,vdiSven Dowideit @ 10:54 pm

I just acquired some ‘new’ computers with 2 Dual Xeons, 32GB and 16GB RAM, and assorted disks.

My first thought was to use the 32GB one as my openstack testbed, and the other as a desktop, but soon after setting them both up with debian testing, I changed my mind.

Dell 690′s are much too noisy to be anywhere near me.

So I tossed my original desktop’s disk into the second one, and then put both of them downstairs, into the ‘server room’, and then set up xpra for rootless persistent X11 sessions. One session per app (browser, irc, email) and one session per project I work on.

Now, I have quiet up here…

Combining this with the rex Box work I was doing last month, and I’m going to have a really nice Software-as-a-Service setup,

for example:

  • rex SaaS:connect –name=”firefox”

would either connect to an existing xpra session by that name, or create a new vm, provision it, and connect to that.

but that code will have to wait, I’m working on the Foswiki 1.2.0 Wiki Applications wizard right now :)
