# Nginx + Certbot
基于官方 `nginx:latest`,内置 `certbot`,用于在容器内执行证书申请与续期。
## 基础镜像
- `nginx:latest`
## 包含组件
| 组件 | 说明 |
|------|------|
| nginx | 官方镜像默认版本 |
| certbot | Let's Encrypt 客户端 |
## 构建
```bash
# 使用构建脚本
./rebuild.sh nginx
# 或直接使用 docker build
docker build -t timi/nginx-certbot:latest ./nginx
```
## 使用
### 运行 Nginx
```bash
docker run -d --name nginx \
-p 80:80 \
-p 443:443 \
-v $(pwd)/nginx.conf:/etc/nginx/nginx.conf:ro \
-v $(pwd)/conf.d:/etc/nginx/conf.d:ro \
-v $(pwd)/certs:/etc/letsencrypt \
timi/nginx-certbot:latest
```
### 申请/续期证书
```bash
docker exec -it nginx certbot certonly --nginx -d example.com
```
### 申请/续期泛解析证书
需要添加 TEXT 解析记录支持
```bash
docker exec -it nginx bash
certbot certonly --server https://acme-v02.api.letsencrypt.org/directory --manual --preferred-challenges dns -d *.example.com
```
### 查看证书有效期
```bash
docker exec -it nginx bash
certbot certificates | awk '/Certificate Name:/ {name=$3} /Expiry Date:/ {printf "%s: %s %s\n", name, $3, $4}'
```
证书会写入 `/etc/letsencrypt`,请持久化该目录。
