配置运行镜像和工具链

适用场景

当托管 Runner 的预装工具链不符合项目需求——需要特定语言版本、专用依赖、或完整构建环境——可通过 container 字段指定自定义 Docker 镜像。

配置说明

container 字段基本用法

# 配置运行镜像和工具链
stages:
  - name: build
    jobs:
      - name: maven-build
        runs-on: {ubuntu-24,x64,medium}
        container:
          image: maven:3.9-eclipse-temurin-21     # 使用 Maven + JDK21 镜像
        steps:
          - run: mvn clean package

container 字段完整配置

jobs:
  - name: custom-env
    runs-on: {ubuntu-24,x64,medium}
    container:
      image: myregistry.example.com/myapp-builder:2.0
      credentials:
        username: ${{ secrets.REGISTRY_USERNAME }}
        password: ${{ secrets.REGISTRY_PASSWORD }}
      env:
        BUILD_MODE: release
        JAVA_HOME: /usr/lib/jvm/java-21
      volumes:
        - /data/cache:/cache
      options: --hostname builder-node --memory 12g
    steps:
      - run: make release

字段	说明
image	Docker 镜像全称（含标签）
credentials	私有镜像仓库认证，引用 Secret
env	容器内环境变量
volumes	挂载卷（Host → Container）
options	Docker run 附加参数

自定义镜像构建

若公共镜像无法满足需求，可自建镜像并推送至镜像仓库：

# Dockerfile.ci
FROM ubuntu:24.04

RUN apt-get update && apt-get install -y \
    build-essential cmake git \
    python3.12 python3-pip \
    nodejs npm \
    && rm -rf /var/lib/apt/lists/*

RUN pip3 install pytest black mypy

WORKDIR /workspace

docker build -t myregistry.example.com/ci-builder:1.0 -f Dockerfile.ci .
docker push myregistry.example.com/ci-builder:1.0

# .gitcode/workflows/custom.yml
jobs:
  - name: full-build
    runs-on: {ubuntu-24,x64,medium}
    container:
      image: myregistry.example.com/ci-builder:1.0
      credentials:
        username: ${{ secrets.REGISTRY_USERNAME }}
        password: ${{ secrets.REGISTRY_PASSWORD }}
    steps:
      - run: pytest
      - run: make build
