gitlab-build-images/kaniko

registry.gitlab.com/gitlab-org/gitlab-build-images/kaniko

This is an image that wraps and extends kaniko. It contains the following tools:

• kaniko: A tool to build images in Docker / Kubernetes
• crane: A tool for managing container images (without the need to download them from registries)
• jq: a lightweight and flexible command-line JSON processor

With this image you can build images without the need for Docker-in-Docker. The image is based on alpine:git, so you can utilize apk and git as well.

If you use this image in GitLab CI, it automatically logs in with credentials provided in GitLab CI.

Usage
