This is tested with Traefik 1.7
This is how to redirect the root or base path to a sub path in Traefik using Docker labels:
Goals
https://example.com
->https://example.com/abc/xyz/
https://example.com/
->https://example.com/abc/xyz/
https://example.com/something
-> no redirect
We will match <begin of line>https://<any chars but not slash AS group1><slash or nothing><end of line>
and replace it with https://<group1>/abc/xyz/
.
In regex we have to escape a /
character by \/
. In docker-compose labels we need to escape again, so that it becomes \\\\/
.
We also need to escape $
to $$
because of docker-compose.
labels:
- "traefik.frontend.rule=Host:example.com"
- "traefik.frontend.redirect.regex=^https:\\\\/\\\\/([^\\\\/]+)\\\\/?$$"
- "traefik.frontend.redirect.replacement=https://$$1/abc/xyz/"
- "traefik.port=80"
- "traefik.enable=true"
steffres, first all, thank you for you help.
In the end I made it work with:
The
addprefix
middleware could be a alternative but:.prefix=
part on label;HTTP 504
again... then after carefully look the log, I figured out that docker swarm keeps some dirt config for traefik and traefik had theaddprefix
andreplacepathregex
, then after adocker service update --force
It worked for some time but traefik stopped after some seconds loggin499 Client Closed Request' caused by: context canceled
.
