Swarm Issues
Raw
gistfile1.txt
#### Known issues & lessons learned in Swarm:
1. When joining nodes to the cluster (using docker run -d swarm join --addr...), the = between addr is optional.
2. When joining nodes to the cluster (using docker run -d swarm join --addr...), do NOT use tcp:// after --addr.
3. When joining nodes to the cluster (using docker run -d swarm join --addr...), on AWS at least use only the DNS name after --addr.
4. tcp:// is required in the DOCKER_HOST env variable. [ e.g.: export DOCKER_HOST=tcp://<DNS-of-host>:9999 ]
5. In AWS at least, while setting environment variable DOCKER_HOST, use only the DNS hostname and not localhost even if you are on the swarm manager.

    • localhost instead of DNS-of-host may work, but is problematic at least in AWS
