webapp/WEB-INF/jboss-config.xml

<jboss-web xmlns="http://www.jboss.com/xml/ns/javaee" version="8.0">
    <context-root>/</context-root>
</jboss-web>

If I deploy by my own hands to wildfly on host machine, everything runs as expected and on root page I see my index.xhtml. But when I deploy it to docker, localhost:8080/ shows default wildfly welcome page. In logs in docker I see Registered web context: '/' for server 'default-server', but still nothing changes
