Can I create a windows based docker swarm?


(Ralph Kincade) #1

can I used %100 docker running on windows 2016 for a swarm , will this work or is it still unsupported ?

You can currently create or join a swarm-mode cluster on Windows with v1.13 or v1.14/master, but overlay networking will need a future Windows update before it will work. Both Linux & Windows nodes can be in the same swarm.

@stefanscherer posted a working setup in Vagrant on GitHub https://github.com/StefanScherer/docker-windows-box/tree/master/swarm-mode . Check out the scripts for the basics but it works essentially the same way as on Linux - docker swarm init, docker swarm join

I am a litte confused about this , the new swarm the one that works with just a “swarm intit” I think this is called “swarm mode” , so this cluster here I did a docker info should work right ?

this is what I a currently looking at


(Patrick Lang) #5

can you try docker node ls? The new swarm mode in v1.13+ doesn’t show all nodes with docker info, only the current one.


(Ralph Kincade) #6

right on. I can see the nodes with “docker node ls” and they do not appear
correctly with UCP , this is expected behavior . I was looking only at UCP
and thinking it was not working
thanks !

I am revising this issue with a vengeance what is the official way to do this ?

I am attempting to run in Azure a Swarm cluster that can run both Linux and Windows containers
