Forgot to mention that I collocated consul_agent with api_worker and also enabled it in server mode and removed it as a separate vm.
Even after this, the consul_agent process was not coming up in router..

Hi Amit

Pls let me know if consul as a separate vm is necessary for cf-231 deployment, though we collocate consul_agent in every other job of cf-231

Regards

Your first job has consul services, so you'll need to colocate the consul_agent there too. You also don't have any consul servers running anywhere.

Hi Amit
I am using cf-231 release.
In the spiff generated yml, I could combine api_worker and cloud_controller jobs into one, dea-spare with router.
But when I remove consul as a separate VM and combine it with api_worker and cloud_controller . The consul process is not starting in router and haproxy.
If I have a separate consul vm, this problem doesn’t occur.

Following is the consul process error in router.

error during start: timeout exceeded

++ logger -p user.info<http://user.info> -t vcap.consul-agent

Pls let me know how can I fix this.
