Hello All,
We have a requirement where in we have multiple services deployed on our
container and these containers are in a cluster spread across different
hosts.
Below is our Infra design
It has 2 hosts which have fuse software instlled. ssh is not available
between the 2 nor is internet access. all containers created are children of
either host.
Fuse ESB Version 6 and patch 5
• All containers on same version
• seprate profile for web service
• 3 jvms (2 root and one extra on server2) for ensemble cluster. These will
not host any applications. They are purely meant for zookeeper registry.
• Camel/cxf fabs to be deployed in web service profile
• 2 jvms/containers for web services(one on each host)
• Setup custom port for webservice 9001.
We thought of achieving load balancing via a load balancer. ie create a vip
for the 2 service endpoints. CSS being the load balancer.
Services are supposed to be deployed in 2 containers with the following
configs:
Web-Service-1 URL =http://ip1:9001/contexrtoor1
Web-Service-1 URL=http://ip2:9001/contextroot1
Web-Service-2 URL =http://ip1:9001/contexrtoor2
Web-Service-2 URL=http://ip2:9001/contextroot2
The web service would be called by the consumers by using a loadbalancer VIP
http://vip/contexroot1 and
http://vip/contextroot2
We were able to cusmtomize the http ports by installing the cxf feature and
pax web server and we have addded a custom filed in the file
org.ops4j.pax.web.properties as org.osgi.service.http.port=9001 now our
container is binded to 9001 but the issue is our web-service ends points are
only accessible as
Web-Service-1 URL =http://ip1:9001/cxf/contexrtoor1
Web-Service-1 URL=http://ip2:9001/cxf/contextroot1
Web-Service-2 URL =http://ip1:9001/cxf/contexrtoor2
Web-Service-2 URL=http://ip2:9001/cxf/contextroot2
http://vip/cxf/contexroot1 and
http://vip/cxf/contextroot2
if we remove '/cxf' from the context root is trowing a 404 error and this is
not acceptable by the dev because as per the design they want the consumers
to access their services as
http://vip/contexroot1 and
http://vip/contextroot2
I know that one solution will be to
Add org.apache.cxf.osgi.cfg file into $FUSE _ESB/etc/ folder, add an
entry
org.apache.cxf.servlet.context=/mycontext
but my doing that it is always explicitly set to only one service , and for
the consumers to access other service again they should have to go through
Web-Service-2 URL =http://ip1:9001/contestroot1/contexrtoor2 , which is not
desired by our architecture team since in future they could be many services
running on this container and each service should have to be independently
accessed.
Please kindly guide me on how to achieve this.
Thanks
