builder-tool

A utility to control the imaginator image building service.

The builder-tool utility may be used to build images from manifests, either locally (for advanced debugging) or by sending a build request to the imaginator image building service.

Usage

Builder-tool supports several sub-commands. There are many command-line flags which provide parameters for these sub-commands. The most commonly used parameter is -imaginatorHostname which specifies which host the imaginator is running on. The -alwaysShowBuildLog parameter is also commonly used. The basic usage pattern is:

builder-tool [flags...] command [args...]

Built-in help is available with the command:

builder-tool -h

Some of the sub-commands available are:

• build-from-manifest: build an image locally from the specified manifest directory and upload a new datestamped image for the specified image stream name. The source image will be fetched from the imageserver
• build-image: request the imaginator to build and upload an image for the specified image stream (this is the most commonly-used sub-command)
• build-raw-from-manifest: build an image locally from the specified manifest and write a RAW image file which can be copied/uploaded for launching VMs. The source image will be fetched from the imageserver
• build-tree-from-manifest: build an image file-system tree locally from the specified manifest directory. The root directory for the tree is created and written to stdout. The source image will be fetched from the imageserver
• get-dependencies: get the dependencies for all the imaginator image streams and write a JSON representation to stdout
• get-digraph: get the image stream dependencies represented as a directed graph suitable for passing to the dot command from the Graphviz tools
• process-manifest: process a manifest locally in the specified root directory containing an already unpacked source image

Security

Imaginator restricts RPC access using TLS client authentication. Builder-tool will load certificate and key files from the ~/.ssl directory. Builder-tool will present these certificates to the imaginator. If one of the certificates is signed by a certificate authority that the imaginator trusts, the imaginator will grant access.
