Docker/HNS networks are misconfigured after Windows reboots

[Dariusz Sosnowski]

Due to network handling logic in Docker on Windows, restart of Docker service causes networks assigned to Contrail CNM plugin to change its driver from 'Contrail' to 'transparent. These networks cannot be used to run containers in Contrail.

Steps to reproduce:

1. Deploy Contrail Windows compute node.
2. Create a Docker network with Contrail driver on the compute node.

        PS C:\> docker network create -d Contrail --ipam-driver windows --opt tenant=admin --opt network=mynetwork mynetwork

3. Inspect docker networks"

        PS C:\> docker network ls
        NETWORK ID NAME DRIVER SCOPE
        1974eb1e785f none null local
        a9c68bd1b66d mynetwork Contrail local

3. Restart Docker service.
4. Inspect docker networks:

        PS C:\> docker network ls

What should happen:

1. mynetwork should have Contrail driver assigned.

       a9c68bd1b66d mynetwork Contrail local

What happens:

1. mynetwork is deleted and Docker reports internal HNS network corresponding to mynetwork:

       5e51f3198de0 Contrail:a9c68bd1b66db28dd7177f8dbbe5e7c9027cda1aa7a46c4400f6149988bb51c7:admin:mynetwork:10.0.5.0/24 transparent local

Win: manual start_mode for Agnt, CNMplg and Docker

When Windows compute node is rebooted, service initialization
requires additional steps (e.g. removing old HNS networks)
before services are started. These steps are going to be performed
by separate script (that is also going to start the services). This
change can be merged before the script is created because current
behavior is incorrect (so the change doesn't break anything).

contrail-autostart script

contrail-autostart script is responsible for cleaning up misconfigured
HNS/Docker networks on the compute node. It's configured with schtasks.exe
to run after boot.
