Docker network mode host port mapping
To have the five IPs be accessible from the Azure Load Balancer, enroll the five IPs in the Azure Load Balancer Backend Address Pool as shown below. You can have five service instances listening on the port on each node.
The following example sets up five IP addresses per node for a Windows/Linux Service Fabric cluster. This allows multiple IP addresses to be configured on each node of the cluster. Set up the network profile section of the Virtual Machine Scale Set resource. So you cant expose ports to the host, because it is the host (as far as the network stack is concerned). When you use -nethost it tells the container to use the hosts networking stack. In the fabricSettings section of the Cluster resource, enable the DNS Service and the IP Provider: "fabricSettings": [ I want the docker container to have same ip as the host with ports exposed. Set up the Azure Resource Manager template. Currently up to 50 IPs per node have been tested and proven stable. In addition, other dependencies such as the load balancer will have other limitations to consider. For high-density scenarios, we recommend nat networking mode. The sum of the number of nodes and the number of container service instances (that are using Open mode) can't exceed 65,356 IPs within a virtual network.
Only the Service Fabric Naming Service or the DNS Service should be used for service discovery.Īzure allows a total of 65,356 IPs per virtual network. For this reason, we don't recommend using the dynamically assigned IP address to discover container services. When a container service restarts or moves to another node in the cluster, the IP address changes. The same docker-compose.yml file can also be used with static port mappings to create multiple services. If you have one container service with a static endpoint in your service manifest, you can create and delete new services by using Open mode without deployment errors. In Open mode, each container service has an internal, dynamically assigned IP address that supports multiple services listening on the same port. To support multiple container services listening on the same port, Service Fabric offers Open networking mode (versions 5.7 and later). When more than one container service is listening on the same port and nat mode is being used, deployment errors can occur. An Azure Service Fabric cluster for container services uses nat networking mode by default.
