I am new to Wildly and Docker
I am trying to build a test cluster of wildfly.
I am using docker compose for orchestration. Following is my docker-compose.yml file
node:
image: wildfly-mgmt
links:
- lb:lb
lb:
image: wildfly-cluster-httpd
ports:
- "9090:80"
After running docker-compose up I can not see the nodes in the mod cluster Management page. http://localhost:9090/mod_cluster_manager It is blank, somehow mod_cluster manager not able to see the nodes...
Docker file for mod cluster:
FROM fedora:latest
RUN yum -y update
RUN yum -y install httpd mod_cluster
RUN yum clean all
RUN sed -i 's|LoadModule proxy_balancer_module|# LoadModule proxy_balancer_module|' /etc/httpd/conf.modules.d/00-proxy.conf
ADD mod_cluster.conf /etc/httpd/conf.d/mod_cluster.conf
EXPOSE 80
CMD ["/sbin/httpd", "-DFOREGROUND"]
Mod_cluster.conf
LoadModule slotmem_module modules/mod_slotmem.so
LoadModule proxy_cluster_module modules/mod_proxy_cluster.so
LoadModule advertise_module modules/mod_advertise.so
LoadModule manager_module modules/mod_manager.so
<IfModule manager_module>
Maxhost 100
ServerName localhost
<VirtualHost *:80>
<Directory />
Require all granted
</Directory>
<Location /mod_cluster_manager>
SetHandler mod_cluster-manager
Require all granted
</Location>
KeepAliveTimeout 60
ManagerBalancerName mycluster
EnableMCPMReceive On
ServerAdvertise On
</VirtualHost>
</IfModule>
I can see the servers running.
> Docker ps
command shows the two containers

I can see the servers running from the console log
node_1 | 19:43:23,828 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0060: Http management interface listening on http://0.0.0.0:9990/management

But the Mod-CLuster_manager is not able to see the nodes. Can anyone please point out what is wrong here? I am really new to this.
