docker-jq

A tiny ~2.5MB* statically linked jq docker image. Since jq only supports writing to stdout a separate image tag is provided that comes packaged alongside busybox.

* The busybox image variant adds an additional ~1MB to the image size.

Supports all upstream alpine docker platforms:

• linux/amd64
• linux/arm64
• linux/arm/v7
• linux/arm/v6
• linux/386
• linux/ppc64le
• linux/s390x
• linux/riscv64

Why

This is a purpose-built image that works great as a Kubernetes init container.
