Windows container failed to start with error, “failed to create endpoint on network nat: HNS failed with error : Failed to create endpoint.”

Question

I have been trying Windows Containers on windows server 2016 TP5. Suddenly I started getting error while running a container with port maping option -p 80:80

Answer 1

I had similar error.

$ docker --version
Docker version 1.13.0-rc3, build 4d92237
$ docker-compose -f .\docker-compose.windows.yml up
Starting musicstore_db_1

ERROR: for db  Cannot start service db: {"message":"failed to create endpoint musicstore_db_1 on network nat: HNS failed with error : Unspecified error"}
ERROR: Encountered errors while bringing up the project.

Static mapping removal did not work, only network removal helped:

Get-ContainerNetwork -Name nat | Remove-ContainerNetwork

Execute the command in PowerShell as administrator, then restart Docker.

Update:

Use CleanupContainerHostNetworking.ps1 script to resolve Docker 17 networking issues.

.\CleanupContainerHostNetworking.ps1 -Cleanup -ForceDeleteAllSwitches
