Container Image Building

Overview

isula-build is a container image build tool developed by the iSula container team. It allows you to quickly build container images using Dockerfiles.

The isula-build uses the server/client mode. The isula-build functions as a client and provides a group of command line tools for image build and management. The isula-builder functions as the server to process client management requests, and runs as a daemon process in the background.

Note:

Currently, isula-build supports OCI image format (OCI Image Format Specification) and Docker image format (Image Manifest Version 2, Schema 2). Use the export ISULABUILD_CLI_EXPERIMENTAL=enabled command to enable the experimental feature for supporting OCI image format. When the experimental feature is disabled, isula-build will take Docker image format as the default image format. Otherwise, isula-build will take OCI image format as the default image format.
