Dockerfile.ci 模板

FROM alpine:latest

# 安装时区数据和证书
RUN apk add --no-cache tzdata ca-certificates

# 设置时区
ENV TZ=Asia/Shanghai

# 复制构建好的二进制文件
# 注意：需要在 docker build 时通过 --build-arg 传递 BINARY_NAME
# 或者直接写死二进制文件名
ARG BINARY_NAME=server
COPY ${BINARY_NAME} /app/server

WORKDIR /app

# 健康检查（按需修改端口和路径）
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
  CMD wget --no-verbose --tries=1 --spider http://localhost:8080/health || exit 1

EXPOSE 8080

ENTRYPOINT ["/app/server"]

缓存配置

缓存路径

path: |
  ~/go/pkg/mod           # Go 模块缓存
  ~/.cache/go-build      # Go 构建缓存

Key 计算

HASH=$(sha256sum go.mod go.sum | sha256sum | awk '{print $1}' | head -c 16)

---

构建参数说明

CGO_ENABLED=0      # 禁用 CGO，生成静态链接二进制
GOOS=linux         # 目标操作系统
GOARCH=amd64       # 目标架构

-ldflags '-s -w'   # 去除符号表和调试信息，减小体积
-X main.GitTag=... # 注入版本信息

---

Secrets 配置

Secret	用途
REGISTRY_PASSWORD	Docker Registry 密码
RELEASE_TOKEN	Gitea API 令牌（创建 Release）

---

常见代码生成工具

根据项目使用的框架，在 Build 步骤中添加相应的生成命令：

框架/工具	命令
Ent (ORM)	go tool ent generate ./schema
Wire (DI)	go tool wire ./...
oapi-codegen	go tool oapi-codegen -config oapi.yaml api.yaml
Stringer	go tool stringer -type=MyType ./...
Protobuf	protoc --go_out=. --go-grpc_out=. *.proto
go generate	go generate ./...

---

使用步骤

1. 复制上方 workflow 模板到 .gitea/workflows/your-service.yml
2. 修改 SERVICE_PREFIX 和 SERVICE_DIR 为实际值
3. 修改 paths 和 tags 触发条件
4. 根据项目需求填充 "用户自定义构建步骤" 部分
5. 创建 Dockerfile.ci 文件
6. 配置 Secrets
7. 推送代码触发 workflow

---

版本发布

# 创建并推送 tag
git tag your-service-1.0.0
git push origin your-service-1.0.0
