* The `tags:` key in values must be a top level key. Globals and nested `tags:` tables
are not currently supported.
#### Importing Child Values via requirements.yaml
In some cases it is desirable to allow a child chart's values to propagate to the parent chart and be
shared as common defaults. An additional benefit of using the `exports` format is that it will enable future
tooling to introspect user-settable values.
The keys containing the values to be imported can be specified in the parent chart's `requirements.yaml` file
using a YAML list. Each item in the list is a key which is imported from the child chart's `exports` field.
To import values not contained in the `exports` key, use the [child/parent](#using-the-child/parent-format) format.
Examples of both formats are described below.
##### Using the exports format
If a child chart's `values.yaml` file contains an `exports` field at the root, its contents may be imported
directly into the parent's values by specifying the keys to import as in the example below:
```yaml
# parent's requirements.yaml file
...
import-values:
- data
```
```yaml
# child's values.yaml file
...
exports:
data:
myint: 99
```
Since we are specifying the key `data` in our import list, Helm looks in the the `exports` field of the child
chart for `data` key and imports its contents.
The final parent values would contain our exported field:
```yaml
# parent's values file
...
myint: 99
```
Please note the parent key `data` is not contained in the parent's final values. If you need to specify the
parent key, use the 'child/parent' format.
##### Using the child/parent format
To access values that are not contained in the `exports` key of the child chart's values, you will need to
specify the source key of the values to be imported (`child`) and the destination path in the parent chart's
values (`parent`).
The `import-values` in the example below instructs Helm to take any values found at `child:` path and copy them
to the parent's values at the path specified in `parent:`
```yaml
# parent's requirements.yaml file
dependencies:
- name: subchart1
repository: http://localhost:10191
version: 0.1.0
...
import-values:
- child: default.data
parent: myimports
```
In the above example, values found at `default.data` in the subchart1's values will be imported
to the `myimports` key in the parent chart's values as detailed below:
```yaml
# parent's values.yaml file
myimports:
myint: 0
mybool: false
mystring: "helm rocks!"
```
```yaml
# subchart1's values.yaml file
default:
data:
myint: 999
mybool: true
```
The parent chart's resulting values would be:
```yaml
# parent's final values
myimports:
myint: 999
mybool: true
mystring: "helm rocks!"
```
The parent's final values now contains the `myint` and `mybool` fields imported from subchart1.
