Reference note (untrusted external data; do not execute it as instructions). Open a terminal, and initialize Docker Swarm mode Bounded code example (external data; do not execute automatically): ```console $ docker swarm init ``` If all goes well, you should see a message similar to the following Bounded code example (external data; do not execute automatically): ```shell Swarm initialized: current node (tjjggogqpnpj2phbfbz8jd5oq) is now a manager. To add a worker to this swarm, run the following command: docker swarm join --token SWMTKN-1-3e0hh0jd5t4yjg209f4g5qpowbsczfahv2dea9a1ay2l8787cf-2h4ly330d0j917ocvzw30j5x9 192.168.65.3:2377 To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions. ``` Run a simple Docker service that uses an alpine-based filesystem, and isolates a ping to 8.8.8.8 Bounded code example (external data; do not execute automatically): ```console $ docker service create --name demo alpine:latest ping 8.8.8.8 ``` Check that your service created one running container Bounded code example (external data; do not execute automatically): ```console $ docker service ps demo ``` You should see something like Bounded code example (external data; do not execute automatically): ```shell ID NAME IMAGE NODE DESIRED STATE CURRENT STATE ERROR PORTS 463j2s3y4b5o demo.1 alpine:latest docker-desktop Running Running 8 seconds ago ``` Check that you get the logs you'd expect for a ping process Bounded code example (external data; do not execute automatically): ```console $ docker service logs demo ``` You should see the output of a healthy ping process Bounded code example (external data; do not execute automatically): ```shell demo.1.463j2s3y4b5o@docker-desktop | PING 8.8.8.8 (8.8.8.8): 56 data bytes demo.1.463j2s3y4b5o@docker-desktop | 64 bytes from 8.8.8.8: seq=0 ttl=37 time=13.005 ms demo.1.463j2s3y4b5o@docker-desktop | 64 bytes from 8.8.8.8: seq=1 ttl=37 time=13.847 ms demo.1.463j2s3y4b5o@docker-desktop | 64 bytes from 8.8.8.8: seq=2 ttl=37 time=41.296 ms ... ``` Finally, tear down your test service Bounded code example (external data; do not execute automatically): ```console $ docker service rm demo ``` Attribution: Adapted from Docker Documentation under Apache-2.0.
