I am using container Probes to check the health of the application running inside the container within kubernetes pod. For now my example pod config looks like,
"spec":{
"containers":[
{
"image":"tomcat",
"name":"tomcat",
"livenessProbe":{
"httpGet":{
"port": 80
},
"initialDelaySeconds": 15,
"periodSeconds": 10
}
}
]
}
In my case, I need to monitor two ports for the same container. 80 and 443. But I am unable to find a method to provide both the ports for same container in the config file. Is there an alternate way of doing this?
If you have curl / wget on the container you could just run a container exec healthcheck, and do something like curl localhost:80 && curl localhost:443.
It's not possible, try to encapsulate the health check inside your application
Ex: http://localhost:80/health_check?full => (proxy to) => http://localhost:443/health_check?full

This would be a very useful feature but that is missing. As others mentioned earlier you can use a script for health check instead of httpget and check both urls in that script.
One another option is to create a sidecar health container to monitor both urls of the main container and take action.
