You most likely either:
    use the binary for the wrong platform
    the binary is not statically linked (has not all the necessary libraries)
You can use CGO_ENABLED=0 to build your binary statically.

Docker Swarm

docker service create \
  --name=viz \
  --publish=8000:8080/tcp \
  --constraint=node.role==manager \
  --mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \
  manomarks/visualizer

Docker Network

  • docker network create --driver overlay my_network_name

Docker Remove Network

  • docker network rm my_network_name
Error - response from daemon: network docker_gwbridge id 4231cbbf8269fb3136c75e734a10fb8f20251b369dc26f5bbbde4aedfe4615c8 has active endpoints
Solution - Can you try using --force to disconnect the container?
docker network disconnect --force <network> release_diyaserver_1

Deploying the service

  • docker service ls
  • docker service create --name=service_name --replicas=1 --network=my_network_name -p=6767:6767 someprefix/image_name
