Build tool to containerize cloud applications.

Requirements

Setup

Usage

 USAGE
     ctz = ctz help
     ctz <filename> <options> = builds images of all modules and pushes them to remote repository
    
 OPTIONS
     -l |  --log       logs the standard output in the console
     -p |  --push      pushes the images to specified repository
     -h |  --help      get detailed usage information
     -v |  --version   get version of the package

 EXAMPLES
    ctz build.yaml
    ctz build.yaml --log
    ctz build.yaml -l
    ctz build.yaml --push
    ctz build.yaml -p --log

Configuration

The following fields are allowed in the YAML file.

Field Description Mandatory
_schema-version schema version of the containerize yaml file.
repository registry where your images/modules will be pushed. ☑️
tag global tag used for all images/modules.
before-all list of commands to execute before building images/modules.
modules list of modules. ☑️

Configuration of modules

There are three ways to configure how to containerize a module:

  1. buildpack: Cloud Native buildpacks to containerize a module.

    Example:

    modules:
    - name: bookshop-srv
      build-parameters:
        buildpack:
          type: nodejs
          builder: builder-jammy-base
          path: gen/srv
          env:
            BP_NODE_RUN_SCRIPTS: ""

    type (optional): Mention the buildpack(s) (comma-separated if multiple).
    There are certain keywords which when mentioned in type key of buildpack which are parsed as:


    Keyword Parsed to
    nodejs gcr.io/paketo-buildpacks/nodejs
    java gcr.io/paketo-buildpacks/java
    sap-machine gcr.io/paketo-buildpacks/sap-machine
    executable-jar gcr.io/paketo-buildpacks/executable-jar
    spring-boot gcr.io/paketo-buildpacks/spring-boot
    syft gcr.io/paketo-buildpacks/syft

    builder: Specify the builder type.
    There are certain keywords which when mentioned in builder key of buildpack which are parsed as:


    Keyword Parsed to
    builder-jammy-base paketobuildpacks/builder-jammy-base
    builder-jammy-buildpackless-base paketobuildpacks/builder-jammy-buildpackless-base
    builder-jammy-full paketobuildpacks/builder-jammy-full
    builder-jammy-buildpackless-full paketobuildpacks/builder-jammy-buildpackless-full

    path : Path of the module to be containerized.

    env: Environment variables (key-value pairs).

    Note: pack CLI tool is required for this option.

  2. dockerfile: Dockerfile provided by the user is used.

    Example:

    modules:
    - name: bookshop-srv
      build-parameters:
        dockerfile: <path to a docker file>
  3. commands: List of commands provided by the user are executed to build the image.

    Example:

    modules:
    - name: bookshop-srv
      build-parameters:
        commands:
        - command 1
        - command 2
        - command 3

    Note: These commands are executed as is without any validation.
