Did you ever wish 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 obtainable regionally? What about integrating CML right into a CI/CD pipeline, which incorporates the creation and destruction of your entire pipeline, together with CML?
You would possibly assume one reply to those issues can be to make use of CML within the cloud. And also you’d be proper. Nonetheless, up till just lately, the one supported platforms to run CML had been both on naked steel servers or on VMware vSphere.
We’ve got heard requests to have CML Software program-as-a-Service (SaaS), and we’re working laborious to make this a actuality sooner or later. Our first step on this path is to offer tooling and automation so you may deploy your CML occasion into Amazon Net Companies (AWS)! This tooling is on the market as of at this time on GitHub.
Setting expectations
With this primary step of automation and tooling comes a couple of limitations, together with:
- Tooling is at the moment solely supported on AWS. We’re engaged on making this additionally obtainable on Azure in a subsequent launch.
- It solely helps an all-in-one deployment. Subsequent releases may embrace deployment of a number of cases to kind a CML cluster.
- This strategy wants a bare-metal taste to help all node varieties. Metallic flavors are dearer than virtualized cases; nonetheless, AWS doesn’t help virtualization extensions on their non-bare-metal flavors. That is totally different from Azure.
- It’s worthwhile to carry your personal AWS occasion AND your personal CML license. No pay-as-you-go consumption mannequin is on the market as of at this time.
- CML software program and reference platform recordsdata from the “refplat ISO” must be made obtainable in a bucket.
- Automation should run regionally in your pc, significantly a Linux machine with Terraform.
Because of the nature of CML’s operate, the flexibility to run it within the cloud won’t ever be low cost (as in free-tier). CML requires quite a lot of assets, reminiscence, disk, and CPU, which comes at a price, no matter whether or not you run it regionally in your laptop computer, in your knowledge heart, or within the cloud. The concept 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 (also needs to work on a Mac with the identical packages put in by way of Homebrew)
- a Bash shell (in case you utilize the add device, which is a Bash script)
- a Terraform set up
- the AWS CLI bundle (awscli with the aws command)
- the CML software program bundle (.pkg) and the CML reference platform ISO from CCO/cisco.com
An present 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 recordsdata obtainable to repeat to an AWS S3 bucket. You additionally should obtain the CML distribution bundle from the Cisco help web site and replica it to the AWS S3 bucket.
For extra element, seek advice from 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 recordsdata, you’ll discover the precise process straight ahead and meticulously documented within the README.md.
Listed below are the elemental steps:
-
- Configure the required S3 bucket, person, insurance policies, secrets and techniques, and guidelines by way of AWS console (as soon as).
- Add the binary recordsdata (photos and software program) into the created bucket (as soon as or each time new software program is on the market).
- Configure the tooling by modifying 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 tackle of the controller is supplied consequently (“output” from Terraform)
- Use CML within the cloud and revenue!
When you’re achieved, tear down the cloud infrastructure by executing terraform destroy.
Word: Whereas no price is incurred if you end up not working CML cases, you’ll nonetheless have to pay for storing the recordsdata 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 price for bare-metal cases or the present dependency on AWS. Or you may want a pay-as-you-go service or one thing else. Tell us!
Simply bear in mind subsequent steps are forward! Keep tuned, and inform us what you assume within the meantime. We’re extraordinarily excited about 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 difficulty tracker venture.
