Docker Cloud Swarm mode - Unable to query docker version

(Space01couk) #1

Have recently setup Docker Cloud swarm mode on Azure. My local Mac shows Docker Version 17.12.0-ce-mac55 (23011). I am logged in with the same account i use on docker cloud

I setup my swarms on azure

docker-machine create -d azure
–azure-subscription-id $AZURE_SUBSCRIPTION_ID
–azure-resource-group my-resource-group
–azure-availability-set my-availability-set
–azure-docker-port 2376
–azure-vnet my-vnet
–azure-subnet my-subnet
–azure-location UKSouth
–azure-ssh-user myuser
–azure-open-port 80
–azure-size “Standard_B1s”

Initialised my swarm using eth0

docker swarm init --listen-addr 192.168.0.X:2377

joined workers to the swarm

docker swarm join --token XXX 192.168.0.X:2377

used docker login to login on the nodes

deployed my private repo on the manager node

docker service create --with-registry-auth --replicas 1 -p 80:80 --name myapp --update-delay 10s --update-parallelism 1 myuser/myprviaterepo

everything fine

docker-manager ls showed

mynode-1 - azure Running tcp://XXX.XXX.XXX.XXX:2376 v18.02.0-ce

port 2376 is open on azure

service all deployed and working

i then wanted to connect my swarm to the Bring your own swarm feature on Docker Cloud.

ran the command it suggested on docker cloud on the manager node

docker run -ti --rm -v /var/run/docker.sock:/var/run/docker.sock dockercloud/registration

it downloaded the server proxy repo and prompted to login to my cloud account

docker service ls shows the proxy service deployed

XXX dockercloud-server-proxy global 1/1 dockercloud/server-proxy *:2376->2376/tcp

and i can now see my swarm on docker cloud with a green light and it offers that others can connect to it using

docker run --rm -ti -v /var/run/docker.sock:/var/run/docker.sock -e DOCKER_HOST dockercloud/client myuser/myswarm

however when i do a docker-machine ls on my mac i now see

mynode-1 - azure Running tcp://XXX.XXX.XXX.XXX:2376 Unknown Unable to query docker version: Get https://XXX.XXX.XXX.XXXX:2376/v1.15/version: x509: cannot validate certificate for XXX.XXX.XXX.XXX because it doesn’t contain any IP SANs

was displaying version fine right up to the point i used the BYOS feature on docker cloud

any suggestions?
