Wonder if they have an idle/spin up time. Only their one instance plan is $5, but I know I have to buy more than one on heroku to get no idle/spin up time - that or use hacks like constant pingers, etc.. This is important for when I'm doing experiments/UI tests/alpha tests/submitting apps for reviews before they have any consistent traffic, but I don't want them to occasionally get stuck on 15 second spin up times on requests.

There are some websites that will ping your heroku instance every few minutes for free. Works great for me.

I love this idea, and want to try it but I have no experience with Docker (on the todo list). I wanted to spin up an instance of Sphinx Search but no idea how to go about doing it. Maybe creating a set of tutorials will help with this. I can think of two advantages. The first being customers like myself will love it. Second, similar to Linode and their tutorials it will drives a lot of traffic and establishes your re…

Absolutely. Along similar lines, DigitalOcean has done a great job of encouraging the community to write tutorial and articles, and as a result there are tons of resources to get you started with all kinds of ways to use a VPS. Doing the same would be tremendously beneficial for Stackdock.

Great initiative! One thing to be aware is that Docker is using LXC for containers and LXC relies on kernel isolation and cgroup limits. The concern is about the vulnerabilities. It is comforting that Heroku is also using LXC for dynos. Would be interesting to know how much in-house adjustments to the kernel and LXC has been made to ensure the hardening.

I work at ActiveState on Stackato, which is a private Platform as a service. Similar to Heroku, only for private hosting (e.g. you host it on your own hardware or hypervisor). We use Docker as of our v3 beta release today (http://beta.stackato.com/). Our use of docker in 3.0+ means that we bring their tuned security along with us (they integrate with apparmor really well, in fact they require it to start up a container). Here's a really good overview of LXC (and docker) security in general: http://blog.docker.io/2013/08/containers-docker-how-secure-a...

Earlier quoted context omitted.

Perhaps http://aws.amazon.com/dedicated-instances/

building a virtualization infrastructure on top of another, black box virtualization infrastructure… What could possibly go wrong?

Hey, it worked for Heroku.

Just curious, how are people building Docker images these days? Doesn't it only run on 64-bit Linux? I have a 32 bit Linux desktop and a Mac and haven't gotten around to installing Docker. At work I have a 64 bit Linux desktop and it seemed to be extremely picky about the kernel version so I gave up.

Are people running Linux VMs on their Macs to build containers?

I like the idea of this service. But both the client side and the server side have to be easy. Unless I'm missing something it seems like they made the server side really easy, but the client side is still annoying.

Sounds like you took the best parts of digital ocean and are trying to push it as a platform with docker baked in. I like. It seems like you're also trying to simplify using docker. I like even more.

Hey - thanks a million - that's the plan!

Speaking of digitalocean, are you guys affiliated at all? Because I get a digitalocean vibe from your pricing/terminology/etc. for some reason.
