为什么端口不暴露？

Question

我在https://hub.docker.com/r/jboss/keycloak之上构建了一个docker映像，如下所示：

FROM jboss/keycloak:10.0.1

ARG DEPLOYMENT

ADD k8s/standalone-ha.xml /opt/jboss/keycloak/standalone/configuration/standalone-ha.xml
COPY k8s/$DEPLOYMENT /opt/jboss/keycloak/import-dir/
COPY ./theme/target/theme-0.0.0.jar /opt/jboss/keycloak/standalone/deployments/databaker-theme.jar
COPY ./spi-profile-registration/target/spi-profile-registration-0.0.0.jar /opt/jboss/keycloak/standalone/deployments/spi-profile-registration.jar

然后我尝试通过docker-compose启动它：

version: '3.7'

services:

  postgres:
    image: postgres:12.2
    container_name: postgres
    environment:
      POSTGRES_DB: keycloak
      POSTGRES_USER: admin
      POSTGRES_PASSWORD: test123

  keycloak:
    image: hub.svc.databaker.io/service/keycloak:0.1.7
    container_name: keycloak
    ports:
      - "8080:8080"
    environment:
      DB_VENDOR: postgres
      DB_ADDR: postgres
      DB_DATABASE: keycloak
      DB_USER: admin
      DB_PASSWORD: test123
      KEYCLOAK_USER: admin
      KEYCLOAK_PASSWORD: test123
      #PROXY_ADDRESS_FORWARDING: "true"
      TZ: UTC
      #KEYCLOAK_DEFAULT_THEME: theme-minimal
      KEYCLOAK_LOGLEVEL: DEBUG
    depends_on:
      - postgres

容器启动并运行后：

CONTAINER ID        IMAGE                                         COMMAND                  CREATED             STATUS              PORTS                NAMES
d9344049e70e        hub.svc.databaker.io/service/keycloak:0.1.6   "/opt/jboss/tools/do…"   22 minutes ago      Up 21 minutes       8080/tcp, 8443/tcp   keycloak
d7a070c41f5c        postgres:12.2                                 "docker-entrypoint.s…"   22 minutes ago      Up 21 minutes       5432/tcp             postgres

端口8080不会在Keycloak容器上暴露-因此无法访问Keycloak。我在做什么错？

码头检查显示：

从我的角度来看，泊坞窗部分很好。我不知道您正在使用dockerfile中的修改来修改什么
