Cloud Deployments


#1

Hey guys,

do you have recommendations for a tool that can spin up new
chef-managed vm instances in AWS and provision them using Chef solo?

My first thought was using the ec2-tools and knife-solo[1], but then I
was looking for a more “integrated” approach. For that mccloud[2] and
vagrant-aws[3] look appealing to me.

Would you recoommend either of them or do you have suggestions for other tools?

Thanks a lot,
Torben

P.S.: from reading the wiki page it appeared to me as knife-ec2 would
be tied to Chef Server usage. True?

We’re looking at the same thing at the moment and we’ve gone with AWS
CloudFormation. There’s a whitepaper on it from Amazon here:
https://s3.amazonaws.com/cloudformation-examples/IntegratingAWSCloudFormationWithOpscodeChef.pdf

That’s from this page:
http://aws.amazon.com/cloudformation/aws-cloudformation-articles-and-tutorials/

Various templates are available here:
http://aws.amazon.com/cloudformation/aws-cloudformation-templates/

That’s not to say the tools you’ve mentioned won’t work, but I’ve not
used them.

Cheers
Nick

We also use CloudFormation with Autoscaler for deploying Hosted Chef
managed instances in AWS. The biggest issues are:

  • Chef bootstrap, since you can’t use any of the knife bootstrap methods
    to launch instances
  • Dealing with the Chef validation key
  • Dealing with encrypted data bag secrets

We use a combination of EC2 instance metadata (user-data), custom bootstrap
scripts and policy-secured S3 buckets to make this all work.

I’d be interested to here how you do ongoing application deployments to
your application servers. We’ve developed our template to the point the
initial deployment works well and scales. Looking at deploying new
versions of our application code to our server we’ve come up with
suspending autoscaling on our app servers, deploying using capistrano
with the capify_cloud plugin (previously capify_ec2), then resuming
scaling. This prevents the race condition where new instances are
started mid deployment and we’d get a mix of code versions deployed.

We’ve looked at a few alternatives such as starting a new stack and
switching DNS entries to that, however we’re using RDS which is part of
the stack, so we’d lose data. We’ve also looked at creating new auto
scaling groups and launch configs within the template and updating the
stack with the new template, but there’s no way to enforce (that I can
see) that the new AS group is up and running and attached to the ELB
before the old one is removed.

The solution we’ve got works, however I don’t think it’s very slick and
I’d like to reduce the moving parts where possible.

Hi Nick, John,

thanks for the responses!

I’m giving Mccloud a try now. I like it because it is just as awesome
as Vagrant is, and supports Chef Solo and Puppet standalone.

CloudFormation is too overkill for my use case (single VM), but
interestingly Mccloud supports the definition of stacks based on
CloudFormation templates as well…

Cheers,
Torben

Not entirely true. Knife bootstraps are all custom templates anyway.
Nothing says you can’t use a custom bootstrap template that just calls
chef-solo instead of chef-client.

Dealing with the Chef validation key
Dealing with encrypted data bag secrets
