反向代理不适用于docker swarm

Question

我使用traefik反向代理。以前，我使用带有反向代理的Docker容器，它可以正常工作。但是，当我切换到docker swarm时，traefik.frontend.rule不会意外运行。只能在Traefik信息中心中使用IP地址和端口。

Docker服务

docker service create 
    --name apiServer 
    --restart-condition=on-failure
    --network="domain-net"
    -p 8889:8889
    --label "traefik.backend=apiServer"
    --label "traefik.frontend.rule=Host:api.domain.com"
    --label "traefik.enable=true"
    --label "traefik.port=8889"
    --label "traefik.docker.network=domain-net"
    --label "traefik.frontend.headers.SSLRedirect=true"
    --label "traefik.frontend.headers.STSSeconds=315360000"
    --label "traefik.frontend.headers.browserXSSFilter=true"
    --label "traefik.frontend.headers.contentTypeNosniff=true"
    --label "traefik.frontend.headers.forceSTSHeader=true"
    --label "traefik.frontend.headers.SSLHost=domain.com"
    --label "traefik.frontend.headers.STSIncludeSubdomains=true"
    --label "traefik.frontend.headers.STSPreload=true"
    --label "traefik.frontend.headers.frameDeny=true"
