Estoy escribiendo un script bash para aprovisionar automáticamente un entorno, pero en la etapa de agregar trabajadores al nodo del administrador, se produce un error.

 #!/bin/bash WORKERSARRAY=(worker1) banner() { figlet SysMonAutogen } create_docker_machine() { docker-machine create \ -d amazonec2 \ --amazonec2-region eu-west-1 \ $1 } create_infrastructure_manager() { echo Generating System Infrastructure... echo creating manager node... create_docker_machine manager echo created manager node... } create_infrastructure_worker() { for i in "${WORKERSARRAY[@]}" do echo creating $i node... create_docker_machine $i echo created $i node... done echo Nodes created... } machine_do() { docker-machine ssh $@ } add_workers() { for i in "${WORKERSARRAY[@]}" do echo adding $i node as worker... machine_do $i docker swarm join --token $WORKER_TOKEN \ $manager_ip:2377 echo added $i node as worker... done echo workers added.. } main() { banner create_infrastructure_manager create_infrastructure_worker manager_ip=$(machine_do manager ifconfig eth0 | grep "inet " | awk F'[: ]+' '{print $4}') machine_do manager sudo docker swarm init --advertise-addr $manager_ip WORKER_TOKEN=$(sudo docker swarm join-token -q worker) add_workers echo infrastructure setup has finished... } main $@

Ejecutar el script produce el siguiente error cuando llega a la etapa de agregar trabajadores:

 remote CA does not match fingerprint

Curiosamente, si accedo manualmente a la máquina y escribo el comando Swarm join, se agrega el nodo.
