'table': Print output in table format with column headers (default)
'table TEMPLATE': Print output in table format using the given Go template
'json': Print in JSON format
'TEMPLATE': Print output using the given Go template.
Refer to https://docs.docker.com/go/formatting/ for more information about formatting output with templates

## Description
Lists the services that are running as part of the specified stack.
> **Note**
>
> This is a cluster management command, and must be executed on a swarm
> manager node. To learn about managers and workers, refer to the
> [Swarm mode section](https://docs.docker.com/engine/swarm/) in the
> documentation.
## Examples
The following command shows all services in the `myapp` stack:
```console
$ docker stack services myapp
ID NAME REPLICAS IMAGE COMMAND
7be5ei6sqeye myapp_web 1/1 nginx@sha256:23f809e7fd5952e7d5be065b4d3643fbbceccd349d537b62a123ef2201bc886f
dn7m7nhhfb9y myapp_db 1/1 mysql@sha256:a9a5b559f8821fe73d58c3606c812d1c044868d42c63817fa5125fd9d8b7b539
```
### Filtering
The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
Multiple filter flags are combined as an `OR` filter.
The following command shows both the `web` and `db` services:
```console
$ docker stack services --filter name=myapp_web --filter name=myapp_db myapp
ID NAME REPLICAS IMAGE COMMAND
7be5ei6sqeye myapp_web 1/1 nginx@sha256:23f809e7fd5952e7d5be065b4d3643fbbceccd349d537b62a123ef2201bc886f
dn7m7nhhfb9y myapp_db 1/1 mysql@sha256:a9a5b559f8821fe73d58c3606c812d1c044868d42c63817fa5125fd9d8b7b539
```
The currently supported filters are:
* id / ID (`--filter id=7be5ei6sqeye`, or `--filter ID=7be5ei6sqeye`)
* label (`--filter label=key=value`)
* mode (`--filter mode=replicated`, or `--filter mode=global`)
* Swarm: not supported
* name (`--filter name=myapp_web`)
* node (`--filter node=mynode`)
* Swarm: not supported
* service (`--filter service=web`)
* Swarm: not supported
### Formatting
The formatting options (`--format`) pretty-prints services output
using a Go template.
Valid placeholders for the Go template are listed below:
| Placeholder | Description |
|-------------|-----------------------------------|
| `.ID` | Service ID |
| `.Name` | Service name |
| `.Mode` | Service mode (replicated, global) |
| `.Replicas` | Service replicas |
| `.Image` | Service image |
When using the `--format` option, the `stack services` command will either
output the data exactly as the template declares or, when using the
`table` directive, includes column headers as well.
The following example uses a template without headers and outputs the
`ID`, `Mode`, and `Replicas` entries separated by a colon (`:`) for all services:
```console
$ docker stack services --format "{{.ID}}: {{.Mode}} {{.Replicas}}"
0zmvwuiu3vue: replicated 10/10
fm6uf97exkul: global 5/5
```
To list all services in JSON format, use the `json` directive:
```console
$ docker stack services ls --format json
{"ID":"0axqbl293vwm","Image":"localstack/localstack:latest","Mode":"replicated","Name":"myapp_localstack","Ports":"*:4566-\u003e4566/tcp, *:8080-\u003e8080/tcp","Replicas":"0/1"}
{"ID":"384xvtzigz3p","Image":"redis:6.0.9-alpine3.12","Mode":"replicated","Name":"myapp_redis","Ports":"*:6379-\u003e6379/tcp","Replicas":"1/1"}
{"ID":"hyujct8cnjkk","Image":"postgres:13.2-alpine","Mode":"replicated","Name":"myapp_repos-db","Ports":"*:5432-\u003e5432/tcp","Replicas":"0/1"}
```
