buildahscript

buildahscript是一种新的容器定义语言，旨在具有命令性和灵活性。

它允许您使用buildargs做更多事情，创建真正可重用的模块，并在一般情况下创建更灵活的容器构建器。

示例

#!/usr/bin/env buildahscript-py
#| pip: requests
#| arg: eula: bool
#| arg: version: str = "latest"
#| arg: type: str = "vanilla"

import tarfile

import requests

    bin = td / 'bin'
    bin.mkdir()
    with Container('rust:buster') as build:
        build.copy_in('cmd', '/tmp/cmd')
        build.copy_in('localmc', '/tmp/localmc')
        build.run(['cargo', 'build', '--release'], pwd='/tmp/cmd')
        build.copy_out('/tmp/cmd/target/release/cmd', bin / 'cmd')

    with Container('rust:buster') as build:
        build.copy_in('status', '/tmp/status')
        build.copy_in('localmc', '/tmp/localmc')
        build.copy_in('mcproto-min-async', '/tmp/mcproto-min-async')
        build.run(['cargo', 'build', '--release'], pwd='/tmp/status')
        build.copy_out('/tmp/status/target/release/status', bin / 'status')

        resp.raise_for_status()
        with tarfile.open(resp, 'r|*') as tf:

        cont.copy_in(bin / 'mc-server-runner', '/mc-server-runner')

        cont.command = ["/mc/launch"]
        cont.healthcheck_cmd = ["status"]
        cont.healthcheck_start_period = "5m"

        return cont.commit()

shpipe

shpipe (#|) 行用于指定buildahscript使用的元数据。基本形式是 #| type: data。

• pip: 从PyPI安装依赖项，作为一个需求指定符
• arg: 定义构建参数，采用Python name:type=default 形式，其中type是类型/解析函数的点形式名称，default是Python字面量。
