Description

Use a shared socket for communication between Buildkit and the Pro Builder containers.

Chart changes:

  • securityContext for buildkit does not need to be set explicitly in the values.yaml file anymore. The appropriate default values are selected based on the value of the buildkit.rootless parameter.

  • BREAKING CHANGE: The buildkit.image parameter is now only used to set the image when buildkit.rootless is false. A new parameter buildkitRootless.image is used to set the image for rootless mode.

Why is this needed?

  • I have raised an issue to propose this change (required)

This simplifies the deployment and removes the need to create and manage mTLS certificates.

Who is this for?

What company is this for? Are you listed in the ADOPTERS.md file?

How Has This Been Tested?

Verified both the root and rootless mode are working on a local k3d cluster.
Verified the builder in rootless mode on an EKS cluster pushing to ECR with IRSA.
