Use https://traefik.me SSL certificates for local HTTPS without having to touch your /etc/hosts or your certificate CA.

Very convenient! It works perfectly !

I just have a problem with CURL inside a php container.

in app1 curl to app2
=> SSL certificate problem: unable to get local issuer certificate

adding curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
works but I would like to avoid having to modify the code inside my app.

I tried a lot of things without success. My knowledge of security certificates is poor...
Any ideas ?

@scaudace download the fullchain.pem and use it as the certFile instead of the cert.pem

  reverse-proxy-https-helper:
    image: alpine
    command: sh -c "cd /etc/ssl/traefik
      && wget traefik.me/fullchain.pem -O cert.pem
      && wget traefik.me/privkey.pem -O privkey.pem"
    volumes:
      - certs:/etc/ssl/traefik

For traefik v3.1.2:

-    defaultRule: "HostRegexp(`{{ index .Labels \"com.docker.compose.service\"}}.traefik.me`,`{{ index .Labels \"com.docker.compose.service\"}}-{dashed-ip:.*}.traefik.me`)"
+    defaultRule: "HostRegexp(`{{ index .Labels \"com.docker.compose.service\"}}-.+.traefik.me`) || HostRegexp(`{{ index .Labels \"com.docker.compose.service\"}}.traefik.me`)"

I was using `defaultRule: 'HostRegexp(`{{ index .Labels "com.docker.compose.service"}}.traefik.me`,`{{ index .Labels "com.docker.compose.service"}}-{dashed-ip:.*}.traefik.me`)'` seams working.
