+## 在 Travis CI 中使用 Docker
+
+当代码提交到 GitHub 时，[Travis CI](https://travis-ci.com/) 会根据项目根目录 `.travis.yml` 文件设置的指令，执行一系列操作。
+
+本小节介绍如何在 Travis CI 中使用 Docker 进行持续集成/持续部署（CI/CD）。这里以当代码提交到 GitHub 时自动构建 Docker 镜像并推送到 Docker Hub 为例进行介绍。
+
+### 准备
+
+首先登录 https://travis-ci.com/account/repositories 选择 GitHub 仓库，按照指引安装 GitHub App 来启用 GitHub 仓库构建。
+
+在项目根目录新建一个 `Dockerfile` 文件。
+
+```dockerfile
+FROM alpine
+
+RUN echo "Hello World"
+```
+
+新建 Travis CI 配置文件 `.travis.yml` 文件。
+
+```yml
+language: bash
+
+dist: xenial
+
+services:
+  - docker
+
+before_script:
+  # 登录到 docker hub
+  - echo "$DOCKER_PASSWORD" | docker login -u "$DOCKER_USERNAME" --password-stdin
+
+script:
+  # 这里编写测试代码的命令
+  - echo "test code"
+
+after_success:
+  # 当代码测试通过后执行的命令
+  - docker build -t username/alpine .
+  - docker push username/alpine
+```
+
+> 请提前在 Travis CI 仓库设置页面配置 `DOCKER_PASSWORD` `DOCKER_USERNAME` 变量
+
+### 查看结果
+
+将项目推送到 GitHub, 登录 [Travis CI](https://travis-ci.com/) 查看构建详情。
