Simple kubectl plugin for rendering and applying Kubernetes manifests

kubectl-deploy

kubectl + render + crypt family

kubectl-deploy it's a really simple kubectl plugin which renders Kubernetes manifests (go-template) and applies them.

The way it works is similar to tiller-less Helm 3, but:

• follows the standard go-template API
• adds custom render functions
• provides Secret Management via crypt
• uses native Kubernetes authorization mechanism (everything is done via kubectl)

Installation

Place kubectl-deploy in your PATH:

curl -#L \
    --url "https://raw.githubusercontent.com/VirtusLab/kubectl-deploy/master/kubectl-deploy" \
    --output "/usr/local/bin/kubectl-deploy"
chmod +x "/usr/local/bin/kubectl-deploy"

More info at Extend kubectl with plugins.

Usage

Ensure kubectl-deploy plugin is recognized by kubectl:

kubectl plugin list

Usage:
  kubectl deploy [flags]

Flags:
      --config string      config.yaml (required)
  -c, --context string     k8s context (optional)
  -d, --debug              enable debug logging level output (optional)
      --dry-run            If true, only print the object that would be sent, without sending it
  -f, --file string        k8s manifest or directory
  -h, --help               help for kubectl
  -n, --namespace string   k8s namespace (optional)
  -t, --trace              enable trace logging level output (optional)

For more advanced templates and rendering please take a look at render#usage.

Examples

Kubernetes manifests

kubectl deploy --file examples/manifests --config examples/config.yaml

Helm Charts

Currently rendering and applying the Helm chart is not supported. Mostly because Helm does not follow the standard go-template API.

As a workaround please use helm template command first.
