In this lesson, we will create a table of all the commands we have used in this section. This will provide a faster reference to the commands. Let's create a table of commands then below.

|   Command  | Options    |  Explanation   |
| --- | --- | --- |
|  `docker swarm init`   |     |  *Makes the current machine a swarm node*   |
|  `docker swarm leave`   |   `-f`  | *Removes the current node from a swarm cluster. The `-f` is used to force a manager node to leave a swarm cluster*    |
|   `docker service create <image name>` |  `-p`, `--env_file`, `--name`, `mount`  |  *Creates a service from an image. `-p` is used to map a host port to a service's tasks ports.*   |
|    `docker network create <name>` |  `--driver`   | *Creates a new network. `--driver` specifies which driver to use for the network*    |
|    `docker service update [Options] <service ID>` |  `--network-add`   | *Updates existing service. You can attach a new network using the `--network-add` option.*    |
|    `docker service [Command] --help` |     | *A quick documentation of every command*    |
|    `docker service ls` |     |  *Lists all the services running on the current node*   |
|    `docker service scale <service Id>=<replica number>` |     |  *Scales services up and down using the replica numbers*   |
|   `docker stack deploy <stack name>`  |  `--compose-file`   |  *Deploys a new stack of services using a compose file. `--compose-file` specifies the compose-file to be used.*   |
|    `docker stack ls` |     |  *Provides information about the current stack*   |
|   `docker stack ps <stack_name>`  |     |  *Lists all the tasks or containers of a stack*   |
|  `docker stack services <stack name>`   |     |  *Lists all the services in the stack*   |
|  `docker stack rm <stack name>`   |     |  *Removes specified stack from swarm*   |
