Did you ever need to run Cisco Modeling Labs however didn’t have the {hardware} or software program to take action? Or have you ever wished to run a topology in your native deployment—however couldn’t since you didn’t have sufficient reminiscence out there domestically? What about integrating CML right into a CI/CD pipeline, which incorporates the creation and destruction of all the pipeline, together with CML?
You would possibly suppose one reply to those issues can be to make use of CML within the cloud. And also you’d be proper. Nonetheless, up till not too long ago, the one supported platforms to run CML had been both on naked steel servers or on VMware vSphere.
Now we have heard requests to have CML Software program-as-a-Service (SaaS), and we’re working arduous to make this a actuality sooner or later. Our first step on this path is to supply tooling and automation so you may deploy your CML occasion into Amazon Net Providers (AWS)! This tooling is accessible as of at this time on GitHub.
Setting expectations
With this primary step of automation and tooling comes just a few limitations, together with:
- Tooling is presently solely supported on AWS. We’re engaged on making this additionally out there on Azure in a subsequent launch.
- It solely helps an all-in-one deployment. Subsequent releases might embrace deployment of a number of situations to kind a CML cluster.
- This method wants a bare-metal taste to help all node sorts. Steel flavors are dearer than virtualized situations; nonetheless, AWS doesn’t help virtualization extensions on their non-bare-metal flavors. That is totally different from Azure.
- You should carry your personal AWS occasion AND your personal CML license. No pay-as-you-go consumption mannequin is accessible as of at this time.
- CML software program and reference platform information from the “refplat ISO” should be made out there in a bucket.
- Automation should run domestically in your laptop, significantly a Linux machine with Terraform.
Because of the nature of CML’s perform, the power to run it within the cloud won’t ever be low-cost (as in free-tier). CML requires numerous assets, reminiscence, disk, and CPU, which comes at a price, no matter whether or not you run it domestically in your laptop computer, in your knowledge middle, or within the cloud. The thought behind the cloud is to simplify operation and supply elasticity however not essentially to save cash.
Assembly software program necessities
The software program necessities you’ll have to efficiently use the tooling embrace:
- a Linux machine (must also work on a Mac with the identical packages put in through Homebrew)
- a Bash shell (in case you utilize the add software, which is a Bash script)
- a Terraform set up
- the AWS CLI package deal (awscli with the aws command)
- the CML software program package deal (.pkg) and the CML reference platform ISO from CCO/cisco.com
An current CML controller satisfies the primary two necessities, and you need to use that to put in Terraform and the AWS CLI. It additionally has the reference platform information out there to repeat to an AWS S3 bucket. You additionally should obtain the CML distribution package deal from the Cisco help web site and duplicate it to the AWS S3 bucket.
For extra element, confer with the “Add script” part of the README.md that’s included within the cml-cloud repository.
Getting up and working
When you’ve put in the necessities and copied the information, you’ll discover the precise process straight ahead and meticulously documented within the README.md.
Listed here are the elemental steps:
-
- Configure the required S3 bucket, person, insurance policies, secrets and techniques, and guidelines through AWS console (as soon as).
- Add the binary information (pictures and software program) into the created bucket (as soon as or at any time when new software program is accessible).
- Configure the tooling by enhancing the config.json file (as soon as).
- Run terraform plan adopted by terraform apply to carry up an occasion
- Wait 5-10 minutes for the system to change into prepared; the deal with of the controller is offered consequently (“output” from Terraform)
- Use CML within the cloud and revenue!
When you’re accomplished, tear down the cloud infrastructure by executing terraform destroy.
Word: Whereas no value is incurred if you end up not working CML situations, you’ll nonetheless have to pay for storing the information contained in the created S3 bucket.
Taking the subsequent steps
Whereas CML AWS automation tooling is a primary step towards CML SaaS, the tooling in its present kind may not suit your wants precisely due to value for bare-metal situations or the present dependency on AWS. Or you may want a pay-as-you-go service or one thing else. Tell us!
Simply keep in mind subsequent steps are forward! Keep tuned, and inform us what you suppose within the meantime. We’re extraordinarily fascinated with how helpful (or not) this primary iteration of cloud tooling is to you and your group and, going ahead, what your particular necessities are. Please attain out to us on the GitHub concern tracker challenge.
