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 a docker and docker-compose which were already working on Centos. I did the following changes to make it work on windows server 2016:

1. Stop the docker service, remove nat, start the docker service.

   ps>stop-service docker
   ps>Get-ContainerNetwork | Remove-ContainerNetwork -Force -ea SilentlyContinue
   ps>start-service docker   
   

2. Configure network in your docker-compose.yml

   version: '3.7'
   networks:
     default:
       external:
         name: nat    
   

That's It!
