Traefik 커맨드 config 파일로 구성하기

왜?

Traefik을 구성하면서 docker-compose.yaml 내부에서 커맨드라인이 너무나 늘어나는 것이다 그러다 보니까 고민이 되었다.

이렇게 작성하면 내가 나중에 잘 알아볼 수 있을까?

그래서 Traefik의 커맨드 설정을 .toml .yaml로 설정하는 방법이 있어서 이 방법으로 커맨드를 옮기려 한다.

Let’s go

Configuration Introduction – Traefik 공식 홈페이지에서 이 부분을 살펴보면 configuration File은 설정파일의 이름이 traefik.toml(.yml, .yaml)으로 설정 되어있고 해당 경로에 있으면 Traefik이 실행되면서 해당 설정을 가져온다.

• /etc/traeifk
• $XDG_CONFIG_HOME/
• $HOME/.config/
• .(the working directory)

처음에는 설정파일로 분리해서 작성할때 매우 만족스러웠다.

하지만 Dynamic conf 에 작성해야하는 것과 static config에 지정해야하는 것을 세세하게 살펴보지 못해서 왜 안되는거지? 하면서 커맨드로 계속 테스트를 해봤다.

traefik의 설정은 모두 끝났고

커맨드로 설정한 것을 /etc/traefik/traefik.yaml로 옮긴다.

그리고 acme 설정을 위해서 /rules/ssl.yaml

certificateResolvers를 tlsChallenge, dnsChallenge 둘다 해봤지만 설정이 안되고 log=DEBUG에서 error와 debug 메세지에서 제대로 설정이 안되는 것을 알게 되었다.

그래서 커맨드로 실행해본 httpChallenge를 토대로 진행해보기로했다.
