How KANIKO Works
Dockerfile Instruction Execution
KANIKO reads the DOCKERFILE and executes instructions inside a container, allowing developers to build images without a Docker daemon.
Userspace Image Building
The tool performs the entire build process in USERSPACE, creating image layers securely while avoiding privileged system access in containerized environments.
Snapshot Layer Creation
KANIKO takes filesystem snapshots after each DOCKERFILE command and converts the changes into container image layers for efficient image construction.
Container Registry Push
After the image is built, KANIKO securely pushes the final container image directly to supported CONTAINER REGISTRIES such as Docker Hub or private registries.
Kubernetes Execution
KANIKO commonly runs inside KUBERNETES pods, allowing image builds to take place safely within cluster-based environments and cloud-native workflows.
Secure CI/CD Integration
KANIKO integrates with modern CI/CD PIPELINES, enabling automated container image builds without granting privileged Docker access to build systems.
