Shipyard with existing Docker-Swarm

Question

I have a Docker Swarm cluster (master + 2 agents). I'm installing Shipyard to have a UI.

cloud-user@docker-mgt:~/wordpress$ curl -sSL https://shipyard-project.com/deploy | bash -s
Deploying Shipyard
 -> Starting Database
 -> Starting Discovery
 -> Starting Cert Volume
 -> Starting Proxy
 -> Starting Swarm Manager
Error response from daemon: Unable to find a node fulfilling all dependencies: --volumes-from=shipyard-certs --link=shipyard-discovery:discovery

I'm running into above error. Any idea why this is?

Answer 1

Both issue 615 and issue 616 point to the same root cause for that error message:

The problem is the deploy script launches an embedded Swarm container.
We should update it to detect an existing Swarm.

If you want to bring your own Swarm manager, you will need the manual deploy: http://test.shipyard-project.com/docs/deploy/manual/
