企业级——容器反向代理利器之traefik

nanyue 2025-03-04 13:23:25 技术文章 8 ℃

traefik

Tr?f?k 是一个云原生的新型的 HTTP 反向代理、负载均衡软件，能轻易的部署微服务。它支持多种后端 (Docker, Swarm, Mesos/Marathon, Consul, Etcd, Zookeeper, BoltDB, Rest API, file...) , 可以对配置进行自动化、动态的管理。

证书

证书生成，采用acme.sh自动生成，推荐neilpang/acme.sh镜像，支持aliyun dns api直接操作dns的创建和修改。

version: "3"
services:
  acme.sh:
    image: neilpang/acme.sh
    container_name: acme.sh
    restart: always
    network_mode: host
    environment:
      - TZ=Asia/Shanghai
      - Ali_Key='替换aliyun的 key'
      - Ali_Secret='替换aliyun的 secret'
      - ACCOUNT_THUMBPRINT='acme.sh 日志中 可以看到 账号信息'

    volumes:
      - ./ssl:/acme.sh
      - ./html:/webroot
    command: daemon

生成泛域名证书

acme.sh --issue --dns dns_ali --force --log -d clibing.com -d \*.clibing.com
