Kubernetes
Improvements to Cluster API provider for GCP (CAPG)
- Description: The Cluster API is a Kubernetes project to bring declarative, Kubernetes-style APIs to cluster creation, configuration, and management. CAPG provides this Kubernetes-native declarative infrastructure for GCP. The project would start with some help wanted issues around quick start and documentation, this will help with understanding mentee with CAPI/CAPG concepts and current implementation. Then we will move on to some long pending improvements documented in the issues link below.
- Recommended Skills: Golang, unit and feature testing.
- Mentor(s): Davanum Srinivas (@dims), Carlos Tadeu Panato Junior (@cpanato)
- Issue: https://github.com/kubernetes-sigs/cluster-api-provider-gcp/issues
Improve SIG-Node testing using Kubetest2
- Description: Kubernetes currently uses Kubetest as the interface for launching and running e2e tests. There is a new kubetest2 that is in the process of being developed and will need to be rolled out to various CI harnesses and jobs. As part of this project we will focus on SIG-Node related CI jobs. Here’s how we currently test SIG-Node related code – e2e-node-tests.md. There will be a lot of interesting problems to solve and this work is critical to how we test kubernetes not just in GCP, but also across all the other cloud providers going forward.
- Recommended Skills: Golang, python, bash, unit and feature testing.
- Mentor(s): Davanum Srinivas (@dims), Amit Watve (@amwat)
- Enhancement : https://github.com/kubernetes/enhancements/tree/master/keps/sig-testing/2464-kubetest2-ci-migration
Kubernetes Policy Working Group (WG)
The Kubernetes policy working group focuses on developing tools and solutions that make Kubernetes secure and easier to use.
KubeArmor support for Policy Report CRD
- Description: This project will periodically generate or update a Policy Report Custom Resource (CR) based on events collected from KubeArmor. This could be implemented as a feature in KubeArmor or developed as an external adapter. The candidate will learn about Kubernetes controllers and various security topics.
- Recommended Skills: Linux, Golang, CLI, Kubernetes

Vitess
Add complete parsing support for MySQL constructs
- Description: Vitess is a database clustering system for horizontal scaling of MySQL. One of the key goals of Vitess is to emulate MySQL behavior even while running multiple MySQL instances so that ORMs and frameworks work seamlessly. Vitess has its own in-built SQL-parser which it uses to understand the query and represent as structs for further processing. As of now, a lot of MySQL constructs are not parsed and result in syntax errors. For example, we do not have complete support to parse partition constructs. Parsing for a lot of the newer features in MySQL 8.0 is also missing. The task of the mentee would be to add parsing support for such constructs.
- Recommended Skills: go, SQL, yacc, compilers and lexers
- Mentor(s): Manan Gupta (@GuptaManan100)
- Issue: https://github.com/vitessio/vitess/issues/8604
Add support for comparing strings using collations and character-sets
- Description: Vitess does not yet have support for collations and character-sets. So, to compare varchar strings Vitess needs to rely on WEIGHT_STRING function for now. As per MySQL documentation, WEIGHT_STRING is a debugging function, meant only for internal use. Having the ability to compare strings using collation and character set support we will be able to better implement ORDER BY, GROUP BY, JOIN. It will also allow us to leverage more advanced join techniques than what we currently implement.
- Recommended Skills: go, SQL
- Mentor(s): Vicent Marti (@vmg)
- Issue: https://github.com/vitessio/vitess/issues/8606
Add support for Upgrade/Downgrade Testing
- Description: Currently Vitess has a rich set of functional tests that are run as part of every commit to catch regressions early. However, they are not sufficient to assess the quality of the product for production rollout. We currently do not test for incompatibilities introduced via upgrade, and ensuring that users can downgrade one level if they need to backout of a failed upgrade. The scenarios will need to be written down, and then tests can be written using GitHub actions:
- Document Supported Upgrade/Downgrade Scenario
- Author GitHub actions tests to checkout 2 versions, test scenarios.
- Recommended Skills: go, GitHub Actions, docker

WasmEdge
Support WASI-Crypto proposal
- Description: After WasmEdge provides an experimental API, WASI Socket, for supporting Berkeley Sockets API in Wasm. WasmEdge enabled a new way to open a new socket, listen to an existed socket, and send and receive data. Moreover, it will be nice if we can do more things in the related features such as SSL support. To achieve this feature, one possible way is to compile the OpenSSL library to Wasm and link it as a library. However, the performance may be not good, because all the computation jobs are done at the wasm level. Here is an alternative way, instead of the previous one, we can wrap the OpenSSL library to Wasm external functions. For example, binding ssl_connect to (import “openssl” “ssl_connect” … ). Unfortunately, this is not an easy way to do it. To simply the workload, we decide to implement the WASI-crypto proposal first, and then use this proposal to make the above things happen.
- Recommended Skills: C++, Rust
- Mentor(s): Hung-Ying Tai (@hydai), Shen-Ta Hsieh (@ibmibmibm)
- Upstream Issue (URL): https://github.com/WasmEdge/WasmEdge/issues/345
Support Wasm-Signature proposal
- Description: The wasm-Signature proposal is specifically about embedded digital signatures in WebAssembly modules, not about package/OCI signatures. When distributing WebAssembly modules, it will be nice if we can have a way to verify. To achieve this target, we choose a Wasm-Signature proposal as our implementation standard. With this proposal, WasmEdge can provide sign and verify features.
- Recommended Skills: C++, Rust
- Mentor(s): Hung-Ying Tai (@hydai), Shen-Ta Hsieh (@ibmibmibm)
- Upstream Issue (URL): https://github.com/WasmEdge/WasmEdge/issues/344
Support WASI-NN proposal
- Description: Machine Learning is a big topic nowadays. WasmEdge already provides a set of TensorFlow host functions to enable the ML inference in WebAssembly. However, these TensorFlow host functions are defined by us and they are just a Wasm function binding from the TensorFlow C API. Here comes a standard, the WASI-NN proposal provides a new way to perform neural network inferencing by using a runtime-provided implementation that can leverage host native optimizations, CPU multi-threading, or powerful hardware devices such as GPUs or TPUs.
- Recommended Skills: C++, Rust
- Mentor(s): Hung-Ying Tai (@hydai), Yi-Ying He (@q82419)
- Upstream Issue (URL): https://github.com/WasmEdge/WasmEdge/issues/343
Support Wasm-C-API proposal
- Description: The wasm-c-api proposal provides the C and C++ API for WASM runtimes. Even though WasmEdge already provided the C API, it’s proper to implement the wasm-c-API proposal for the general C/C++ API. In the current status, we’ve already implemented the non-runtime data structures on the branch. Then, we need to finish the runtime implementation.

Tremor
Solidify and generalize error handling code in the runtime
- Description: The runtimes error handling code stems from ancient times where rust was younger, and we were more naive. As such, it is more grown than designed in many places. With the knowledge of the past three years and stabilization of the codebase, now is a good time to polish it and make errors an exciting user experience.
- Recommended Skills: rust

Thanos
Add groupcache (and improve) backend for the caching bucket in Thanos Store
- Description: This project is about implementing the groupcache back-end for the caching bucket. Caching bucket is a generic mechanism for caching requests to remote object storage. All of the other caching mechanisms currently suffer from the cache stampede problem and it is impossible to “properly” solve this problem with them. This is where groupcache comes in. Some work has already been done so you will have to something work off of. Groupcache also needs some improvements with regards to fetching multiple keys at once to improve the performance even more. In the end your work will make not just Thanos faster but also cheaper because less requests will need to be made to the remote object storage.

Migrate Thanos to the New Protocol Buffers v2 API
- Description: This project is about updating and optimizing the protocol buffers implementation used for communication throughout the Thanos project. Thanos relies heavily on gRPC and protocol buffers for communication between its many components, and now with the release of the new Golang API for protocol buffers and the deprecation of the old API, Thanos should be updated to benefit from the improvements in the ecosystem. As part of this project, the protocol buffers generator used in Thanos will be migrated to one that supports the new API and brings other improvements, such as reducing memory allocations. This project will help make Thanos faster and ensure that we stay up to date with the latest libraries.
- Recommended Skills: Go, protocol buffers
- Mentor(s): Lucas Servén Marín (@squat), Kemal Akkoyun (@kakkoyun), Giedrius Statkevičius (@GiedriusS)
- Upstream Issue (URL): https://github.com/thanos-io/thanos/issues/4557
Add metrics to track the progress for compaction and downsampling
- Description: This project is about improving the observability of the Thanos compactor component to help user track the current progress. Thanos compactor usually has to deal with large TSDB blocks for compaction and downsampling. When the data are large, it takes a long time to finish the compaction or downsampling. Now users have to check the bucket UI manually to see whether the work is done. It would be better to have a more fine-grained way to tell the progress of compaction and downsampling. We can have some metrics to track the work and even integrate the stats into the UI.

Buildpacks
Update Builder implementation to 0.1 Builder Spec
- Description: In Cloud Native Buildpacks, Builders are distributed OCI images that act as the complete context for the building of an application. They came into existance by necessity and have risen to be an essential concept that now needs a specification. As part of this project, you will help us make the necessary changes to pack to adhere to the specification as well as finalize the specification itself. This will have to be done with consideration to existing implementations in efforts to prevent unintentionally breaking anyone’s existing workflow.

OpenEBS
A Kubernetes operator to remove stale PVs of failed statefulset replicas
- Description: When using StatefulSets with Local Volumes on Ephemeral Nodes – the StatefulSet Pods will get stuck in pending state when the Node is taken out of the cluster. In such cases, manual steps are required to verify that Node is out of the cluster, remove the PV and PVC and delete the failed StatefulSet replica to trigger the re-creation of a new replica with a new PVC/PV on a new node. This enhancement request is to build a generic operator that is driven by a configuration to automate the manual steps.
