docs: add reference for "docker config" commands
This is mostly a copy of the equivalent `docker secret` commands, which uses the same mechanisms behind the hood (hence, are 90% the same). We can make further refinements to these docs, but this gives us a starting point. Adding these documents, because there were some links pointing to these pages in the docs, but there was no markdown file to link to on GitHub. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

|

Options:

-f, --format string Format the output using the given Go template
|

```
|
||||
|
||||
## Description
|
||||
|
||||
Inspects the specified config.
|
||||
|
||||
By default, this renders all results in a JSON array. If a format is specified,
|
||||
the given template will be executed for each result.
|
||||
|
||||
Go's [text/template](http://golang.org/pkg/text/template/) package
|
||||
describes all the details of the format.
|
||||
|
||||
For detailed information about using configs, refer to [store configuration data using Docker Configs](https://docs.docker.com/engine/swarm/configs/).

|
||||
|
||||
## Examples
|
||||
|
||||
### Inspect a config by name or ID
|
||||
|
||||
You can inspect a config, either by its *name*, or *ID*
|
||||
|
||||
For example, given the following config:
|
||||
|
||||
```bash
|
||||
$ docker config ls
|
||||
|
||||
ID NAME CREATED UPDATED
|
||||
eo7jnzguqgtpdah3cm5srfb97 my_config 3 minutes ago 3 minutes ago
|
||||
```
|
||||
|
||||
```bash
|
||||
$ docker config inspect config.json
|
||||
```
|
||||
|
||||
The output is in JSON format, for example:
|
||||
|
||||
```json
|
||||
[
|
||||
{
|
||||
"ID": "eo7jnzguqgtpdah3cm5srfb97",
|
||||
"Version": {
|
||||
"Index": 17
|
||||
},
|
||||
"CreatedAt": "2017-03-24T08:15:09.735271783Z",
|
||||
"UpdatedAt": "2017-03-24T08:15:09.735271783Z",
|
||||
"Spec": {
|
||||
"Name": "my_config",
|
||||
"Labels": {
|
||||
"env": "dev",
|
||||
"rev": "20170324"
|
||||
},
|
||||
"Data": "aGVsbG8K"
|
||||
}
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
### Formatting
|
||||
|
||||
You can use the --format option to obtain specific information about a
|
||||
config. The following example command outputs the creation time of the
|
||||
config.
|
||||
|
||||
```bash
|
||||
$ docker config inspect --format='{{.CreatedAt}}' eo7jnzguqgtpdah3cm5srfb97
|
||||
|
||||
2017-03-24 08:15:09.735271783 +0000 UTC
|
||||
```

|
||||
mem02h8n73mybpgqjf0kfi1n0 test_config 3 seconds ago 3 seconds ago
|
||||
```
|
||||
|
||||
### 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"`)
|
||||
|
||||
The currently supported filters are:
|
||||
|
||||
- [id](#id) (config's ID)
|
||||
- [label](#label) (`label=<key>` or `label=<key>=<value>`)
|
||||
- [name](#name) (config's name)
|
||||
|
||||
#### id
|
||||
|
||||
The `id` filter matches all or prefix of a config's id.
|
||||
|
||||
```bash
|
||||
$ docker config ls -f "id=6697bflskwj1998km1gnnjr38"
|
||||
|
||||
ID NAME CREATED UPDATED
|
||||
6697bflskwj1998km1gnnjr38 q5s5570vtvnimefos1fyeo2u2 6 weeks ago 6 weeks ago
|
||||
```
|
||||
|
||||
#### label
|
||||
|
||||
The `label` filter matches configs based on the presence of a `label` alone or
|
||||
a `label` and a value.
|
||||
|
||||
The following filter matches all configs with a `project` label regardless of
|
||||
its value:
|
||||
|
||||
```bash
|
||||
$ docker config ls --filter label=project
|
||||
|
||||
ID NAME CREATED UPDATED
|
||||
mem02h8n73mybpgqjf0kfi1n0 test_config About an hour ago About an hour ago
|
||||
```
|
||||
|
||||
The following filter matches only services with the `project` label with the
|
||||
`project-a` value.
|
||||
|
||||
```bash
|
||||
$ docker service ls --filter label=project=test
|
||||
|
||||
ID NAME CREATED UPDATED
|
||||
mem02h8n73mybpgqjf0kfi1n0 test_config About an hour ago About an hour ago
|
||||
```
|
||||
|
||||
#### name
|
||||
|
||||
The `name` filter matches on all or prefix of a config's name.
|
||||
|
||||
The following filter matches config with a name containing a prefix of `test`.
|
||||
|
||||
```bash
|
||||
$ docker config ls --filter name=test_config
|
||||
|
||||
ID NAME CREATED UPDATED
|
||||
mem02h8n73mybpgqjf0kfi1n0 test_config About an hour ago About an hour ago
|
||||
```
|
||||
|
||||
### Format the output
|
||||
|
||||
The formatting option (`--format`) pretty prints configs output
|
||||
using a Go template.
|
||||
|
||||
Valid placeholders for the Go template are listed below:
|
||||
|
||||
| Placeholder | Description |
|
||||
| ------------ | ------------------------------------------------------------------------------------ |
|
||||
| `.ID` | Config ID |
|
||||
| `.Name` | Config name |
|
||||
| `.CreatedAt` | Time when the config was created |
|
||||
| `.UpdatedAt` | Time when the config was updated |
|
||||
| `.Labels` | All labels assigned to the config |
|
||||
| `.Label` | Value of a specific label for this config. For example `{{.Label "my-label"}}` |
|
||||
|
||||
When using the `--format` option, the `config ls` command will either
|
||||
output the data exactly as the template declares or, when using the
|
||||
`table` directive, will include column headers as well.
|
||||
|
||||
The following example uses a template without headers and outputs the
|
||||
`ID` and `Name` entries separated by a colon (`:`) for all images:
|
||||
|
||||
```bash
|
||||
$ docker config ls --format "{{.ID}}: {{.Name}}"
|
||||
|
||||
77af4d6b9913: config-1
|
||||
b6fa739cedf5: config-2
|
||||
78a85c484f71: config-3
|
||||
```
|
||||
|
||||
To list all configs with their name and created date in a table format you
|
||||
can use:
|
||||
|
||||
```bash
|
||||
$ docker config ls --format "table {{.ID}}\t{{.Name}}\t{{.CreatedAt}}"
|
||||
|
||||
ID NAME CREATED
|
||||
77af4d6b9913 config-1 5 minutes ago
|
||||
b6fa739cedf5 config-2 3 hours ago
|
||||
78a85c484f71 config-3 10 days ago
|
||||
```
