Semantic Release 镜像

概述和主要用途

由Renovate Bot维护的基础镜像，用于自动化版本管理和发布流程。基于Semantic Release工具，支持在CI/CD环境中实现版本号自动生成、发布日志创建等功能。镜像源码仓库：[] Release官方文档：[]

核心功能和特性

• 提供Semantic Release运行环境，支持自动化版本控制和发布流程
• 集成GitLab CI，可输出发布环境变量文件（release.env）并作为制品存储
• 支持通过Cosign工具验证镜像签名，确保镜像完整性和安全性
• 提供Cyclonedx格式证明验证，支持供应链安全审计

使用场景和适用范围

适用于需要自动化版本管理的项目，尤其适合集成到GitLab CI/CD流水线中，实现版本号自动管理、发布日志生成、发布包推送等自动化流程。

使用方法和配置说明

GitLab CI配置示例

以下是在GitLab CI中使用该镜像的基础配置：

yaml
semantic-release:
  image: hoppr/semantic-release:latest
  script:
    - semantic-release
  artifacts:
    paths:
      - release.env
    reports:
      dotenv: release.env

镜像验证

可通过Cosign工具验证镜像签名，公钥可在镜像Releases页面获取。签名将通过Rekor透明度日志验证。

验证命令示例

使用crane获取镜像摘要，结合yq提高输出可读性：

bash
$ export DGST=$(crane digest hoppr/semantic-release:latest)
$ export COSIGN_PUB_KEY=$(cat cosign.pub)
$ COSIGN_EXPERIMENTAL=1 cosign verify --key env://COSIGN_PUB_KEY hoppr/semantic-release@$DGST | yq eval -P -

验证输出示例：
