docker - Should Swarm Master Join As Node in a Single Node Cluster? -


we building small cluster, , (strange) requirement setup in 1 machine, other machines can join in future.

i set consul with:

docker run -d -p 8500:8500 --name=consul progrium/consul -server -bootstrap

and master with:

docker run -d -p 4000:4000 swarm manage -h :4000 --advertise <ip_here>:4000 consul://<ip_here>:8500

where docker run with:

sudo docker daemon -h tcp://0.0.0.0:2375 -h unix:///var/run/docker.sock

and docker -h :4000 info lists nodes 0 @ stage, cannot run images docker -h :4000 run <image> because no healthy node available in cluster.

when join master node cluster with:

docker run -d swarm join --advertise=<ip_here>:2375 consul://<ip_here>:8500

then docker -h :4000 info lists nodes 1, , can run containers.

please note <ip_here> refers same ip of machine.

is intended behaviour? if not, doing wrong?

after seeing docker machine's way of creating swarm cluster, using swarm integrated docker v1.12.0, wanted post update. swarm master join swarm cluster, running 2 containers, agent , master.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
