Traefik 日志在哪里？

Question

您是否知道 Traefik 日志的位置？我阅读了有关 Traefik 的文档，它说它会输出到标准输出，但是当我使用 docker-compose up -d 启动 docker 容器时，在我尝试域名并拉出多个链接的 docker 容器后，标准输出中没有显示任何内容。

我也尝试指定这些：

[traefikLog]
  filePath = "./traefik.log" #<--Tried this but It doesn't work, file empty and permissions set to 777

[accessLog]
  filePath = "./access.log" #<--Tried this but doesn't work, file empty and permissions set to 777

我很困惑，我错过了什么吗？还是 Traefik 应该这么安静？

当我运行它时，我看到的就是这些，之后什么都没有。

# docker-compose up
Creating traefik ... done
Attaching to traefik

附上我的配置。谢谢。

traefik/traefik.toml:

logLevel = "DEBUG"
defaultEntryPoints = ["http","https"]

[api]
  address = ":8080"

[traefikLog]
  filePath = "./traefik.log" #<--Tried this but It doesn't work

[accessLog]
  filePath = "./access.log" #<--Tried this but doesn't work

[entryPoints]
  [entryPoints.http]
    #redirect ALL http traffic to https 443
    address = ":80"
    [entryPoints.http.redirect]
      entryPoint = "https"
  [entryPoints.https]
    address = ":443"
    [entryPoints.https.tls]

#Let's encrypt setup
[acme]
  email = "email@email.com"
  storage = "acme.json"
  entryPoint = "https"
  acmeLogging = true
  #When new host is created, request certificate.
  onHostRule = true
  onDemand = false
  [acme.httpChallenge]
    entryPoint = "http"

#Watch Docker, when new containers are created with label create mapping.
[docker]
  endpoint = "unix:///var/run/docker.sock"
  domain = "exampledomain.net"
  watch = true
  exposedbydefault = false

docker-compose.yml:

version: '3'
services:
  traefik:
    hostname: traefik
    domainname: exampledomain.net
    image: traefik:alpine
    command: --api --docker
    container_name: traefik
    networks:
      - nginx-proxy
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
      - "./traefik/traefik.toml:/traefik.toml"
      - "./traefik/acme.json:/acme.json"
    labels:
      - "traefik.enable=true"
      - "traefik.port=8080"
      - "traefik.frontend.rule=Host:monitor.exampledomain.net"
      - "traefik.docker.network=nginx-proxy"

networks:

Answer 1

如果您运行docker-compose up -d，要查看标准输出事件中的日志：

docker-compose log -f

https://docs.docker.com/compose/reference/logs/

仅供参考，路径 ./traefik.log 在 Traefik 容器内。

[traefikLog]
  filePath = "./traefik.log" 

通过您的文件（没有[traefikLog] 部分），我看到了日志。

但是，您的配置存在一些问题：

version: '3'
services:
  traefik:
    hostname: traefik
    domainname: exampledomain.net
    image: traefik:v1.7.9-alpine
    # command: --api --docker # <-- don't define the same configuration with CLI and TOML https://docs.traefik.io/basics/#static-traefik-configuration
    container_name: traefik
    networks:
      - nginx-proxy
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
      - "./traefik/traefik.toml:/traefik.toml"
      - "./traefik/acme.json:/acme.json"
    labels:
      - "traefik.enable=true"
      - "traefik.port=8080"
      - "traefik.frontend.rule=Host:monitor.exampledomain.net"
      - "traefik.docker.network=nginx-proxy"

networks:
  nginx-proxy:
    external:
      name: nginx-proxy

logLevel = "DEBUG"
defaultEntryPoints = ["http","https"]

[api]
  # address = ":8080" <- this options doesn't exist. https://docs.traefik.io/v1.7/configuration/api/

# [traefikLog] # <-- remove because not needed
#   filePath = "./traefik.log"

# [accessLog] # <-- remove because not needed
#   filePath = "./access.log"

[entryPoints]
  [entryPoints.http]
    address = ":80"
    [entryPoints.http.redirect]
      entryPoint = "https"
  [entryPoints.https]
    address = ":443"
    [entryPoints.https.tls]

# Let's encrypt setup
[acme]
  email = "email@email.com"
  storage = "acme.json"
  entryPoint = "https"
  acmeLogging = true
  onHostRule = true
  onDemand = false
  [acme.httpChallenge]
    entryPoint = "http"

[docker]
  endpoint = "unix:///var/run/docker.sock"
  domain = "exampledomain.net"
  # watch = true # <---- useful only for swarm
  exposedbydefault = false

我正在共享一个 docker-compose 文件，该文件将为访问日志和服务日志创建一个卷：

"networks":
  "network":
    "external":
      "name": "appliance"
"services":
  "container":
    "container_name": "traefik"
    "image": "traefik:1.7.4"
    "networks":
    - "network"
    "ports":
    - "80:80"
    - "443:443"
    - "8099:8099"
    "restart": "always"
    "volumes":
    - "/var/run/docker.sock:/var/run/docker.sock"
    - "{pwd}/traefik.toml:/traefik.toml"
    - "{pwd}/acme.json:/acme.json"
    - "logs:/var/log/traefik"
"version": "3.4"
"volumes":
  "logs":
    "name": "traefik_logs"

在traefik.toml中添加日志位置如下：

[accessLog]
filePath = "/var/log/traefik/access.log"

Answer 3

只需将[accessLog] 添加到您的traefik.toml 文件中即可。
