Question 1

How do I use Kaniko with a private Git repository?

Accepted Answer

Kaniko supports private Git repos by passing personal access tokens in the URL (e.g., git://TOKEN@github.com/repo) or via environment variables like GIT_TOKEN, as detailed in the README's 'Using Private Git Repository' section.

Question 2

Kaniko vs BuildKit: which is better for Kubernetes builds?

Accepted Answer

Kaniko is daemonless and runs securely in Kubernetes without disabling seccomp, while BuildKit requires nested containers and may need security adjustments. However, BuildKit is actively maintained and supports more features like multi-arch builds with QEMU.

Question 3

Can Kaniko build multi-architecture container images?

Accepted Answer

Kaniko itself doesn't create multi-arch manifests, but you can use external tools like manifest-tool to combine images built separately for different architectures, as outlined in the README's multi-arch section.

Question 4

How to cache layers in Kaniko to speed up builds?

Accepted Answer

Enable caching with --cache=true and specify a cache repository with --cache-repo; layers from RUN and COPY commands can be stored remotely or locally using --cache-dir for faster subsequent builds.

Question 5

Why is Kaniko archived and should I still use it?

Accepted Answer

Kaniko is archived due to lack of ongoing development, so it's not recommended for new projects. Existing users might rely on it, but alternatives like BuildKit or Buildah offer active support and newer features.

Question 6

Does Kaniko support ARM64 architecture?

Accepted Answer

Yes, the official Kaniko executor image supports ARM64 and other architectures like s390x, but you must run it on compatible hardware or in environments that can execute those binaries.
