| + | |||
| + | Now, it is good idea to ALWAYS add the advertise and listener address to the server: | ||
| + | |||
| + | Manually, workers and manager can be joined to the swarm as follows: | ||
| + | |||
| + | < | ||
| + | docker swarm join --token SWMTKN-1-4mqe4htimsl9wrlzstzx6c18qmibjfjuuihdp3o91pnmssbvml-1h1yrqixgrme7aypq6c4m0npj \ | ||
| + | manager_advertise_ip: | ||
| + | --advertise-addr worker_advert_ip_addr: | ||
| + | --listener-addr worker_listen_ip_addr: | ||
| + | </ | ||
| + | |||
| + | Insert the correct token depending on, if you are adding worker or a manager. The above is for worker. | ||
