traefik.yml

Agora vamos criar o nosso ficheiro estático de configuração do Traefik. Utilizem o vaosso editor preferido para adicionar/editar o ficheiro e colar a configuração a baixo. Neste exemplo vou usar o vim. Certifiquem-se que onde virem TEU_DOMINIO.TDL , TUA_REDE_DOCKER ou [email protected], alteram com os vossos dados.

NOTA - IPs Cloudflare

Os IPs da Cloudflare na config a cima podem não estar atualizados. É da vossa responsabilidade garantir que estão corretos.

Para evitar intervenção manual podem utilizar um plugin para gerir os IPs da Cloudflare:

Se quiserem obter os IPs de forma manual, podem tentar executar(créditos salty):

curl https://api.cloudflare.com/client/v4/ips | sed 's/\\//g' | yq '.result.ipv4_cidrs + .result.
