Resource classes favoring higher CPU (not ram)

What:Resource classes that introduce higher CPU without additional memory, balancing the credits required accordingly.Why:Current resource class options all step CPU & RAM in ratio of 1:2. Some use cases are heavily CPU bound, but not memory bound, and for various architectural limitations of these 3rd testing tools are not capable of leveraging GPU class machines. Ideally these classes would ahve a ratio of 1:1 or even 2:1 of CPU:MemExample Libraries/Tools benefiting:Visual regression testing tools like https://github.com/americanexpress/jest-image-snapshot have been cited as examples of CPU intensive needs.

Cache Docker images on Docker executor

Currently, DLC only applies to the actual building of Docker images within jobs. It'd be nice to enable DLC for the actual spin up of environment Docker images, since those tend to vary wildly from just a few seconds to a few minutes. Enabling DLC will allow for consistently fast spinup of environment. CCI-I-1004

MongoDB

add a mongo db service image. as of now I am not really able to run my backend tests. The old convenience images where quite handy in that regard. Or I can choose to run against an old mongodb version, which is against the purpose though.

Windows Docker Layer Caching

The windows environment should have docker layer caching so that its capabilities are in line with the linux environment. This would be particularly useful because windows docker images are substantially larger than their linux counterparts. For our use case, we are pulling a 30gb image with each build and it is taking around 30 minutes. If DLC was available our total build time would go from ~35 minutes to ~5minutes. CCI-I-1182

Chrome/Chromium Support for Arm

Request to support Chrome / Chromium on -browsers variants of Docker images on Arm

Re-introduce "latest" tags for next-gen convenience images

Customers want to always be using the latest versions of a major release (e.g., 12.x) without having to explicitly specify/change the version each time in the configuration.

Terraform Docker Image

Having a CircleCI-customized Terraform Docker image would be super helpful! CCI-I-758

Add Helm Diff plugin to cimg/deploy

The cimg/deploy image has Helm. We heavily use the Helm Diff plugin (listed at https://helm.sh/docs/community/related/ ) to check and record what changes were or are about to be deployed to kubernetes. We currently install the plugin in our CI jobs but would be convenient to have this pre-installed in cimg/deploy

Docker Images hosted in AWS

It would be great to have the cimg/ images hosted in a public registry inside of AWS as well as DockerHub.

Cache convenience images on each host

It is advised to use convenience images. Adoption would grow when these images would be cached to reduce the time needed for everyone to spin up the environment. Right now spinning up the environment takes between 30 and 60 seconds already.
