Add Common Expression Language (CEL) #322
Description
Activity
@kazk would an example setup similar to codewars/riscv speed up the process of adding CEL support to Codewars? If so, I might work on one in the coming weeks subject to availability, minus the following deliverables:
- Conversion to Codewars test output format - we can probably refer to the Codewars Go setup afterwards
- CodeMirror syntax highlighting - not too familiar with it
@kazk An example setup is now available at DonaldKellett/codewars-cel and I've invited you as a collaborator to the repository; feel free to take a look and reach out in case of any suggestions or outstanding issues 😄
The example setup demonstrates 3 cases based on rejecting Pods with gitRepo volumes using CEL expressions, motivated by the recent CVE-2024-10220 vulnerability:
- Passing tests
- Failing tests
- Syntax error
Just realized that the current Codewars Go setup uses Ginkgo+Gomega for unit testing, I've migrated the examples over from Testify to Ginkgo+Gomega
The official CEL SVG logo taken from cel.dev:
Perhaps we can use a variant thereof for our Codewars CEL logo?
Motivation
Common Expression Language (CEL) is a domain-specific language with bounded execution time optimized for defining authorization policies, validating API requests and transforming data.
CEL was initially developed by Google and widely adopted within Kubernetes and the wider cloud-native ecosystem, e.g.:
Introducing CEL support on Codewars opens the doors to a new class of policy authoring and data validation challenges tailored to cloud infrastructure and DevOps engineers who may not necessarily be well-versed in programming and software development. Furthermore, Qualified customers can leverage CEL support for interview challenges tailored to DevOps and platform engineering roles.
