Did you ever wish to run Cisco Modeling Labs however didn’t have the {hardware} or instrument to take action? Or have you ever sought after to run a topology in your native deployment—however couldn’t as a result of you didn’t have sufficient reminiscence to be had in the neighborhood? What about integrating CML right into a CI/CD pipeline, which contains the introduction and destruction of all the pipeline, together with CML?

It’s possible you’ll suppose one solution to those issues can be to make use of CML within the cloud. And also you’d be proper. On the other hand, up till just lately, the one supported platforms to run CML have been both on naked steel servers or on VMware vSphere.

We’ve got heard requests to have CML Tool-as-a-Provider (SaaS), and we’re operating onerous to make this a fact at some point. Our first step on this course is to supply tooling and automation so you’ll deploy your CML example into Amazon Internet Products and services (AWS)! This tooling is to be had as of nowadays on GitHub.

Environment expectancies

With this primary step of automation and tooling comes a couple of obstacles, together with:

• Tooling is recently simplest supported on AWS. We’re operating on making this additionally to be had on Azure in a next free up.
• It simplest helps an all-in-one deployment. Next releases may just come with deployment of a couple of cases to shape a CML cluster.
• This method wishes a bare-metal taste to make stronger all node sorts. Steel flavors are costlier than virtualized cases; then again, AWS does now not make stronger virtualization extensions on their non-bare-metal flavors. That is other from Azure.
• You want to convey your individual AWS example AND your individual CML license. No pay-as-you-go intake type is to be had as of nowadays.
• CML instrument and reference platform information from the “refplat ISO” want to be made to be had in a bucket.
• Automation will have to run in the neighborhood in your laptop, specifically a Linux gadget with Terraform.

Because of the character of CML’s serve as, the power to run it within the cloud won’t ever be affordable (as in free-tier). CML calls for numerous sources, reminiscence, disk, and CPU, which comes at a price, without reference to whether or not you run it in the neighborhood in your computer, for your information heart, or within the cloud. The theory at the back of the cloud is to simplify operation and supply elasticity however now not essentially to economize.

Assembly instrument necessities

The instrument necessities you’ll want to effectively use the tooling come with:

• a Linux gadget (will have to additionally paintings on a Mac with the similar applications put in by means of Homebrew)
• a Bash shell (when you use the add instrument, which is a Bash script)
• a Terraform set up
• the AWS CLI package deal (awscli with the aws command)
• the CML instrument package deal (.pkg) and the CML reference platform ISO from CCO/cisco.com

An current CML controller satisfies the primary two necessities, and you’ll use that to put in Terraform and the AWS CLI. It additionally has the reference platform information to be had to replicate to an AWS S3 bucket. You additionally will have to obtain the CML distribution package deal from the Cisco make stronger website online and replica it to the AWS S3 bucket.

For extra element, seek advice from the “Add script” segment of the README.md this is integrated within the cml-cloud repository.

Getting up and working

If you’ve put in the necessities and copied the information, you’ll in finding the real process directly ahead and meticulously documented within the README.md.

Listed here are the elemental steps:

1. 1. Configure the specified S3 bucket, consumer, insurance policies, secrets and techniques, and laws by means of AWS console (as soon as).
   2. Add the binary information (pictures and instrument) into the created bucket (as soon as or on every occasion new instrument is to be had).
   3. Configure the tooling by means of enhancing the config.json record (as soon as).
   4. Run terraform plan adopted by means of terraform practice to convey up an example
   5. Wait 5-10 mins for the device to transform in a position; the cope with of the controller is supplied in consequence (“output” from Terraform)
   6. Use CML within the cloud and benefit!

If you’re finished, tear down the cloud infrastructure by means of executing terraform ruin.

Word: Whilst no price is incurred while you aren’t working CML cases, you’ll nonetheless want to pay for storing the information throughout the created S3 bucket.

Taking the following steps

Whilst CML AWS automation tooling is a primary step towards CML SaaS, the tooling in its present shape would possibly now not suit your wishes precisely on account of price for bare-metal cases or the present dependency on AWS. Or you may want a pay-as-you-go provider or one thing else. Tell us!

Simply take into account next steps are forward! Keep tuned, and let us know what you suppose within the interim. We’re extraordinarily excited about how helpful (or now not) this primary iteration of cloud tooling is to you and your company and, going ahead, what your explicit necessities are. Please succeed in out to us at the GitHub factor tracker undertaking.
