## About The Project | ||
|
||
Pod Disruption Budgets (PDBs) help limit the number of concurrent disruptions your application experiences. | ||
This enhances availability while allowing the cluster administrator to manage the cluster nodes. | ||
Unfortunately, kubectl provides limited tooling to interact with PDBs. | ||
|
||
This plugin aims to address this issue with the following key features: | ||
|
||
- Lists all PDBs matching a given workload. | ||
- Lists all workload pods matching a given PDB. | ||
- Creates new PDBs from the command line. | ||
|
||
## Getting Started | ||
|
||
To get a local copy up and running follow these simple example steps. | ||
|
||
### Installation | ||
|
||

``` | ||
brew install dhenkel92/homebrew-tap/kubectl-pdb | ||
``` | ||
|
||
In order to get a newer version, just upgrade via Homebrew | ||
``` | ||
brew upgrade kubectl-pdb | ||
``` | ||
|
||
### Other distributions | ||

## Usage | ||
|
||
``` | ||
Utility to work with pod disruption budgets | ||
Usage: | ||

Available Commands: | ||
completion Generate the autocompletion script for the specified shell | ||
cover Shows which PDBs are covering the given workload. | ||
create | ||
help Help about any command | ||
pods List pods | ||
Flags: | ||
--as string Username to impersonate for the operation. User could be a regular user or a service account in a namespace. | ||
--as-group stringArray Group to impersonate for the operation, this flag can be repeated to specify multiple groups. | ||

--disable-compression If true, opt-out of response compression for all requests to the server | ||
-h, --help help for pdb | ||
--insecure-skip-tls-verify If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure | ||
--kubeconfig string Path to the kubeconfig file to use for CLI requests. | ||
-n, --namespace string If present, the namespace scope for this CLI request | ||
--request-timeout string The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests. (default "0") | ||
-s, --server string The address and port of the Kubernetes API server | ||

--token string Bearer token for authentication to the API server | ||
--user string The name of the kubeconfig user to use | ||
Use "pdb [command] --help" for more information about a command. | ||
``` | ||
|
||
List all pods for a given PDB: | ||
``` | ||
kubectl pdb pods <pdb_name> | ||
``` | ||
|
||
List all PDBs for all pods of a namespace: | ||
``` | ||
kubectl pdb cover -n <namespace> | ||
``` | ||
