NEW: We are working to make it possible to run Linux and Windows containers side-by-side without the Moby Linux VM. Currently the following workaround can be used to ensure IPv6 is enabled on your host machine: C:\> reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters /v DisabledComponents /f We're working on platform changes to automatically detect/prevent this issue.

docker: Error response from daemon: container e15d99c06e312302f4d23747f2dfda4b11b92d488e8c5b53ab5e4331fd80636d encountered an error during CreateContainer: failure in a Windows system call: Element not found. If you're running into an error such as the one below, there's a chance that IPv6 is disabled on your host machine. HNS requires that IPv6 is enabled on container host machinesĪs part of KB4015217 HNS requires that IPv6 is enabled on Windows container hosts. Here's a list of handy tips and insights, inspired by common questions on Windows container networking that we hear from the community. For example, you might use the following command to set the DNS suffix of a network to "" and the DNS servers of a network to 4.4.4.4 and 8.8.8.8: C:\> docker network create -d transparent -o .dnssuffix=abc.com -o .dnsservers=4.4.4.4,8.8.8.8 MyTransparentNetwork Use the option, -o .dnssuffix= to specify the DNS suffix of a network, and the option, -o .dnsservers= to specify the DNS servers of a network. Specify the DNS Suffix and/or the DNS Servers of a Network Note: The value for .interface is the network adapter's Name, which can be found with: PS C:\> Get-NetAdapter For instance, you might use the following command to create a transparent network which is attached to the "Ethernet 2" network interface: C:\> docker network create -d transparent -o .interface="Ethernet 2" TransparentNet2 To bind a network (attached through the Hyper-V virtual switch) to a specific network interface, use the option, -o .interface= to the docker network create command.

For instance, you might use the following command to create a transparent network with a name that is specified to the HNS service: C:\> docker network create -d transparent -o .networkname=MyTransparentNetwork MyTransparentNetworkīind a Network to a Specific Network InterfaceĪpplies to all network drivers except 'nat' If you are creating a network, you can specify the name that it is given by the HNS service using the option, -o .networkname= to the docker network create command. Ordinarily, when you create a container network using docker network create, the network name that you provide is used by the Docker service but not by the HNS service. Specify the Name of a Network to the HNS Service container to container connectivity is needed) for where we don't want NAT'ing to occur, we also need to specify an ExceptionList: C:\> docker network create -d l2bridge -o .enable_outboundnat=true -o .outboundnat_exceptions=10.244.10.0/24 If you are creating a network, you can use the -o .enable_outboundnat= option to apply the OutboundNAT HNS policy to give containers access to the outside world: C:\> docker network create -d l2bridge -o .enable_outboundnat=true MyL2BridgeNetwork

Ordinarily, when you create a l2bridge container network using docker network create, container endpoints do not have an HNS OutboundNAT policy applied, resulting in containers being unable to reach the outside world. When you set the VLAN ID for a network, you are setting VLAN isolation for any container endpoints that will be attached to that network.Įnsure that your host network adapter (physical) is in trunk mode to enable all tagged traffic to be processed by the vSwitch with the vNIC (container endpoint) port in access mode on the correct VLAN. For instance, you might use the following command to create a transparent network with a VLAN ID of 11: C:\> docker network create -d transparent -o .vlanid=11 MyTransparentNetwork To set a VLAN ID for a network, use the option, -o .vlanid= to the docker network create command. C:\> docker network create -d transparent -o .interface="Ethernet 2", "Ethernet 3" TeamedNetĪpplies to transparent and l2bridge network drivers You can take advantage of Switch Embedded Teaming when creating container host networks for use by Docker by specifying multiple network adapters (separated by commas) with the -o .interface option.
