### Error handling
|
||||
|
||||
If there is an error parsing the Resource configuration, kustomize will print an error with the file.
|
||||
|
||||
$ kustomize config grep "spec.template.spec.containers[name=\.*].resources.limits.cpu>1.0" ./staging/ | kustomize config tree --name --resources
|
||||
Error: staging/persistent-volume-provisioning/quobyte/quobyte-admin-secret.yaml: [0]: yaml: unmarshal errors:
|
||||
line 13: mapping key "type" already defined at line 9
|
||||
|
||||
Here the ` + "`" + `staging/persistent-volume-provisioning/quobyte/quobyte-admin-secret.yaml` + "`" + ` has a malformed
|
||||
Resource. Remove the malformed Resources:
|
||||
|
||||
rm staging/persistent-volume-provisioning/quobyte/quobyte-admin-secret.yaml
|
||||
rm staging/storage/vitess/etcd-service-template.yaml
|
||||
|
||||
When developing -- to get a stack trace for where an error was encountered,
|
||||
use the ` + "`" + `--stack-trace` + "`" + ` flag:
|
||||
|
||||
$ kustomize config grep "spec.template.spec.containers[name=\.*].resources.limits.cpu>1.0" ./staging/ --stack-trace
|
||||
go/src/sigs.k8s.io/kustomize/kyaml/yaml/types.go:260 (0x4d35c86)

||||

||||

...

||||
|
||||
|
||||
### Combine ` + "`" + `grep` + "`" + ` and ` + "`" + `tree` + "`" + `
|
||||
|
||||
` + "`" + `grep` + "`" + ` and ` + "`" + `tree` + "`" + ` may be combined to perform queries against configuration.
|
||||
|
||||
Query for ` + "`" + `replicas` + "`" + `:

### Inverting ` + "`" + `grep` + "`" + `
|
||||
|
||||
The ` + "`" + `grep` + "`" + ` results may be inverted with the ` + "`" + `-v` + "`" + ` flag and used to find Resources that don't
|
||||
match a query.
|
||||
|
||||
Find Resources that have an image specified, but the image doesn't have a tag:
|
||||
|
||||
$ kustomize config grep "spec.template.spec.containers[name=\.*].name=\.*" ./ | kustomize config grep "spec.template.spec.containers[name=\.*].image=\.*:\.*" -v | kustomize config tree --image --name

## Configuration Basics
|
||||
|
||||
### Synopsis
|
||||
|
||||
`kustomize config` provides tools for working with local configuration directories.
|
||||
|
||||
First fetch a bundle of configuration to your local file system from the
|
||||
Kubernetes examples repository.
|
||||
|
||||
git clone https://github.com/kubernetes/examples/
|
||||
cd examples/
|
||||
|
||||
### `tree` -- view Resources and directory structure
|
||||
|
||||
`tree` can be used to summarize the collection of Resources in a directory:
|
||||
|
||||
$ kustomize config tree mysql-wordpress-pd/
|
||||
mysql-wordpress-pd
|
||||
├── [gce-volumes.yaml] v1.PersistentVolume wordpress-pv-1
|
||||
├── [gce-volumes.yaml] v1.PersistentVolume wordpress-pv-2
|
||||

|
||||

├── [wordpress-deployment.yaml] v1.Service wordpress
|
||||
└── [wordpress-deployment.yaml] v1.PersistentVolumeClaim wp-pv-claim
|
||||
|
||||
`tree` may be provided flags to print the Resource field values. `tree` has a number of built-in
|
||||
supported fields, and may also print arbitrary values using the `--field` flag to specify a field
|
||||
path.
|
||||
|
||||

### `cat` -- view the full collection of Resources
|

|
||||
$ kustomize config cat mysql-wordpress-pd/

`cat` prints the raw package Resources. This may be used to pipe them to other tools
|
||||
such as `kubectl apply -f -`.
|
||||
|
||||
## `fmt` -- format the Resources for a directory (like go fmt for Kubernetes Resources)
|
||||
|
||||
`fmt` formats the Resource Configuration by applying a consistent style, including
|
||||
ordering of fields and indentation.
|
||||
|
||||
$ kustomize config fmt mysql-wordpress-pd/
|
||||
|
||||
Run `git diff` and see the changes that have been applied.
|
||||
|
||||
### `grep` -- search for Resources by field values
|
||||
|
||||
`grep` prints Resources matching some field value. The Resources are annotated with their
|
||||
file source so they can be piped to other commands without losing this information.
|
||||
|
||||
$ kustomize config grep "metadata.name=wordpress" wordpress/
|
||||
apiVersion: v1
|
||||
kind: Service
|
||||

|
||||

- list elements may be indexed by a field value using list[field=value]

$ kustomize config grep "spec.status.spec.containers[name=nginx].image=mysql:5\.6" wordpress/

||||

|

|

`grep` may be used with kubectl to search for Resources in a cluster matching a value.
|
||||
|
||||
kubectl get all -o yaml | kustomize config grep "spec.replicas>0" | kustomize config tree --replicas

### Error handling
|
||||
|
||||
If there is an error parsing the Resource configuration, kustomize will print an error with the file.
|
||||
|
||||
$ kustomize config grep "spec.template.spec.containers[name=\.*].resources.limits.cpu>1.0" ./staging/ | kustomize config tree --name --resources
|
||||
Error: staging/persistent-volume-provisioning/quobyte/quobyte-admin-secret.yaml: [0]: yaml: unmarshal errors:
|
||||
line 13: mapping key "type" already defined at line 9
|
||||
|
||||
Here the `staging/persistent-volume-provisioning/quobyte/quobyte-admin-secret.yaml` has a malformed
|
||||
Resource. Remove the malformed Resources:
|
||||
|
||||
rm staging/persistent-volume-provisioning/quobyte/quobyte-admin-secret.yaml
|
||||
rm staging/storage/vitess/etcd-service-template.yaml
|
||||
|
||||
When developing -- to get a stack trace for where an error was encountered,
|
||||
use the `--stack-trace` flag:
|
||||
|
||||
$ kustomize config grep "spec.template.spec.containers[name=\.*].resources.limits.cpu>1.0" ./staging/ --stack-trace
|
||||
go/src/sigs.k8s.io/kustomize/kyaml/yaml/types.go:260 (0x4d35c86)
|
||||
(*RNode).GetMeta: return m, errors.Wrap(err)
|
||||
go/src/sigs.k8s.io/kustomize/kyaml/kio/byteio_reader.go:130 (0x4d3e099)
|
||||
(*ByteReader).Read: meta, err := node.GetMeta()
|
||||
...
|
||||
|
||||
|
||||
### Combine `grep` and `tree`
|
||||
|
||||
`grep` and `tree` may be combined to perform queries against configuration.
|
||||
|
||||
Query for `replicas`:
|
||||
|
||||
$ kustomize config grep "spec.replicas>5" ./ | kustomize config tree --replicas
|
||||
.
|
||||

└── staging/volumes/vsphere
|
||||
└── [simple-statefulset.yaml] StatefulSet web
|
||||
└── spec.replicas: 14
|
||||
|
||||
Query for `resource.limits`
|
||||
|
||||
$ kustomize config grep "spec.template.spec.containers[name=\.*].resources.limits.memory>0" ./ | kustomize config tree --resources
|
||||

||||
### Inverting `grep`
|
||||
|
||||
The `grep` results may be inverted with the `-v` flag and used to find Resources that don't
|
||||
match a query.
|
||||
|
||||
Find Resources that have an image specified, but the image doesn't have a tag:
|
||||
|
||||
$ kustomize config grep "spec.template.spec.containers[name=\.*].name=\.*" ./ | kustomize config grep "spec.template.spec.containers[name=\.*].image=\.*:\.*" -v | kustomize config tree --image --name
