我是一個完整的 docker noob。剛剛按照教程安裝了 docker 和 docker-compose 以及 portainer。
現在我想在 portainer 上設定 traefik 反向代理。
這是 /etc/traefik 中的 traefik.yml 檔案
global:
checkNewVersion: true
sendAnonymousUsage: false # true by default
# (Optional) Log information
# ---
# log:
# level: ERROR # DEBUG, INFO, WARNING, ERROR, CRITICAL
# format: common # common, json, logfmt
# filePath: /var/log/traefik/traefik.log
# (Optional) Accesslog
# ---
# accesslog:
# format: common # common, json, logfmt
# filePath: /var/log/traefik/access.log
# (Optional) Enable API and Dashboard
# ---
api:
dashboard: true # true by default
insecure: true # Don't do this in production!
# Entry Points configuration
# ---
entryPoints:
web:
address: :80
# (Optional) Redirect to HTTPS
# ---
# http:
# redirections:
# entryPoint:
# to: websecure
# scheme: https
websecure:
address: :443
# Certificates configuration
# ---
# TODO: Custmoize your Cert Resolvers and Domain settings
#
這是 docker-compose 檔案：
version: '3'
volumes:
traefik-ssl-certs:
driver: local
services:
traefik:
image: "traefik:v2.5"
container_name: "traefik"
ports:
- "80:80"
- "443:443"
# (Optional) Expose Dashboard
- "8080:8080" # Don't do this in production!
volumes:
- /etc/traefik:/etc/traefik
- traefik-ssl-certs:/ssl-certs
- /var/run/docker.sock:/var/run/docker.sock:ro
但是當我嘗試啟動容器時，出現此錯誤：
2021/12/08 18:08:07 命令 traefik 錯誤：yaml：第 19 行：未找到預期的密鑰
當我從 docker-compose 檔案中洗掉“服務”下的整個“卷”部分時，我可以讓容器運行，但我需要它來設定我的 traefik。我不知道我做錯了什么，因為我正在關注這個 1:1 的視頻教程
uj5u.com熱心網友回復：
你能分享整個終端日志嗎？這是容器內部的錯誤嗎？
無論如何，我認為您應該檢查您的 traefik.yml 縮進。有一些不同級別的鍵，YAML 對此非常敏感。我特別講：
- 全球的
- 檢查新版本
- 發送匿名使用
- 介面
檢查它們之前的空格數。
uj5u.com熱心網友回復：
我無法重新創建您的確切錯誤訊息，但是在使用您的確切traefik.yml組態檔（如問題中發布的）時出現錯誤，因為語法無效（如另一個答案中指出的）。
我將撰寫檔案減少到最低限度：
version: '3'
services:
traefik:
image: "traefik:v2.5"
container_name: "traefik"
volumes:
- 'c:\temp\traefik\etc\traefik.yml:/etc/traefik/traefik.yml'
traefik.yml如您所見，僅將檔案安裝到容器中。該檔案如下所示，洗掉了注釋掉的行：
global:
checkNewVersion: true
sendAnonymousUsage: false # true by default
api:
dashboard: true # true by default
insecure: true # Don't do this in production!
entryPoints:
web:
address: :80
websecure:
address: :443
docker-compose up對此運行 a會出現以下錯誤：
c:\Temp\traefik>docker-compose up
[ ] Running 1/0
- Container traefik Created 0.0s
Attaching to traefik
traefik | 2021/12/09 08:44:36 command traefik error: no valid configuration found in file: /etc/traefik/traefik.yml
traefik exited with code 1
當我修復traefik.yml檔案中的縮進（并打開除錯日志記錄）時，我有這個：
global:
checkNewVersion: true
sendAnonymousUsage: false # true by default
api:
dashboard: true # true by default
insecure: true # Don't do this in production!
entryPoints:
web:
address: :80
websecure:
address: :443
log:
level: DEBUG
docker-compose up再次運行我現在得到這個：
c:\Temp\traefik>docker-compose up
[ ] Running 2/2
- Network traefik_default Created 0.2s
- Container traefik Created 29.5s

所以可以看到traefik啟動了。這不一定與您遇到的問題相同，但它顯示了如何解決問題。一旦你知道你的 traefik 配置是好的，你可以添加 DEBUG 日志，然后嘗試添加其他卷和配置，看看它們是否也正常。
