docker - Traefik的ProxyPass/ProxyPassReverse

Question

我想在Docker Swarm中将apache / tomcat ProxyPass配置更改为traefik / tomcat配置。我尝试了一些在这里解释的https://docs.traefik.io/basics/#frontends，但是它不起作用:

Apache配置:

ProxyPass       /sso ajp://server_host:8080/app
ProxyPassReverse    /sso ajp://server_host:8080/app

Docker Swarm配置:

Traefik config in my docker-compose file:
traefik.frontend.rule=Host:external_dns;PathPrefix:/sso;ReplacePath:/app

和Tomcat中具有 war 应用程序的Tomcat图像(上下文为“app”)

但这不起作用， /sso被重定向(302)到 /app
谁可以做从fontend到后端的重定向？

谢谢

编辑param ReplacePathRegex后解决了问题:

traefik.frontend.rule=Host:external_dns;PathPrefix:/sso;ReplacePathRegex:^/sso/(.*) /app/$$1
