root@ird-6-0:~# docker swarm init
Error response from daemon: could not choose an IP address to advertise since this system has multiple addresses on interface eth0 (159.203.67.250 and 10.17.0.46) - specify one with --advertise-addr
root@ird-6-0:~# docker swarm init -h
Flag shorthand -h has been deprecated, please use --help
Usage: docker swarm init [OPTIONS]
Initialize a swarm
Options:
--advertise-addr string Advertised address (format: <ip|interface>[:port])
--autolock Enable manager autolocking (requiring an unlock key to start a stopped manager)
--availability string Availability of the node ("active"|"pause"|"drain") (default "active")
--cert-expiry duration Validity period for node certificates (ns|us|ms|s|m|h) (default 2160h0m0s)
--dispatcher-heartbeat duration Dispatcher heartbeat period (ns|us|ms|s|m|h) (default 5s)
--external-ca external-ca Specifications of one or more certificate signing endpoints
--force-new-cluster Force create a new cluster from current state
--help Print usage
--listen-addr node-addr Listen address (format: <ip|interface>[:port]) (default 0.0.0.0:2377)
--max-snapshots uint Number of additional Raft snapshots to retain
--snapshot-interval uint Number of log entries between Raft snapshots (default 10000)
--task-history-limit int Task history retention limit (default 5)
root@ird-6-0:~# docker swarm init --advertise-addr 159.203.67.250
Swarm initialized: current node (4xu1niz6wea3cwzpdlhc0n1x3) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join \
--token SWMTKN-1-66z98vcwsxo48u2jm1d4fuxm59ygi0mszmvfkl704e49sq4cpp-dcxsx140imu7xcf7z2lyddf2i \
159.203.67.250:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

Run a container with terminal docker run -i -t

-ito connect to STDIN on the container -
-tto get a pseudo-terminal - Note: You need to run a terminal process as your command (e.g. bash)

7. Run a container from the image and specify a bash terminal as your process
8. Check the /data/myvol folder and verify that your file is present- Docker comes with three networks automatically setup
- The bridge network is the docker0 bridge
- By default all containers are connected to the bridge network

Signing and pushing trust metadata
You are about to create a new root signing key passphrase. This passphrase
will be used to protect the most sensitive key in your signing system. Please
choose a long, complex passphrase and be careful to keep the password and the
key file itself secure and backed up. It is highly recommended that you use a
password manager to generate the passphrase and keep it safe. There will be no
way to recover this key. You can find the key in your config directory.
Enter passphrase for new root key with ID 6e95bc8:
Repeat passphrase for new root key with ID 6e95bc8:
