Swarm overlay networking not working with 18.06 and r4.large instances #174

Open gary-cowell opened 5 years ago

gary-cowell commented 5 years ago

Expected behavior

Deploy Docker For AWS CE 18.06 with Worker Instance type r4.large

Actual behavior

Swarm collapses because new workers don't have access to overlay

Information

We can deploy against r3.large and the services start but r3.large is obsolete.

Trying

Full output of the diagnostics from "docker-diagnose" ran from one of the instance

docker-diagnose produces no output

Steps to reproduce the behavior

... deploy Docker For AWS 18.06 with r4.large workers
... there is no 2

Have confirmed that when deploying with Docker for AWS 18.03 , the r4.large workers will operate correctly.

So either upgrading to 18.06, or a fresh deployment of Docker for AWS 18.06 makes no difference - the r4.large instance type fails to correctly operate its networking and make the swarm overlay networks available.
