Docker 错误“无法连接到网络<name> : 超出上下文最后期限。”</name>

Question

I'm trying to run a container that connects to an overlay network in my docker swarm, but I get the following error:

$ docker run --rm --network mystack_default alpine
docker: Error response from daemon: Could not attach to network mystack_default : context deadline exceeded.

The error context deadline exceeded is a go timeout - so it seems like something must be locking / blocking my container from joining this network. How can I figure out what it is?

The swarm cluster is a dev cluster that consists of a single node, the issue appears intermittent but lasts many minutes when it happens. The docker version is 18.09.2 - if it matters?

Answer 1

try to set the node to active:

docker node update --availability active MYNODE

and then try again
