|
## 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
|
||||||
|
```

```
|
||||||
|
|
||||||
|
### 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
|
||||||
|
```
