Portal — Kubernetes admission, audit, NetworkPolicy and response-action engine

portal completion bash

portal completion bash

Generate the autocompletion script for bash

Synopsis

Generate the autocompletion script for the bash shell.

This script depends on the 'bash-completion' package. If it is not installed already, you can install it via your OS's package manager.

To load completions in your current shell session:

source <(portal completion bash)

To load completions for every new session, execute once:

Linux:

portal completion bash > /etc/bash_completion.d/portal

macOS:

portal completion bash > $(brew --prefix)/etc/bash_completion.d/portal

You will need to start a new shell for this setup to take effect.

portal completion bash

Options

  -h, --help              help for bash
      --no-descriptions   disable completion descriptions

SEE ALSO

portal completion fish

portal completion fish

Generate the autocompletion script for fish

Synopsis

Generate the autocompletion script for the fish shell.

To load completions in your current shell session:

portal completion fish | source

To load completions for every new session, execute once:

portal completion fish > ~/.config/fish/completions/portal.fish

You will need to start a new shell for this setup to take effect.

portal completion fish [flags]

portal completion zsh

portal completion zsh

Generate the autocompletion script for zsh

Synopsis

Generate the autocompletion script for the zsh shell.

If shell completion is not already enabled in your environment you will need to enable it. You can execute the following once:

echo "autoload -U compinit; compinit" >> ~/.zshrc

To load completions in your current shell session:

source <(portal completion zsh)

To load completions for every new session, execute once:

Linux:

portal completion zsh > "${fpath[1]}/_portal"

macOS:

portal completion zsh > $(brew --prefix)/share/zsh/site-functions/_portal

You will need to start a new shell for this setup to take effect.

portal completion zsh [flags]

portal init-certs

portal init-certs

Generate webhook TLS material and inject the CA bundle into the ValidatingWebhookConfiguration

Synopsis

init-certs is the cert-bootstrap step for Portal installs that do not use cert-manager. It is invoked from a Pod-level init-container in the Helm chart.

The command is idempotent: if the named Secret already holds a valid cert that is not within the renewal window, only the ValidatingWebhookConfig's caBundle is patched (a no-op when already correct). Otherwise a fresh self-signed CA + leaf are generated, the Secret is written in place, and the caBundle is patched.

The generated cert is mirrored to --cert-dir so the main container's filesystem mount reads the new material regardless of kubelet's Secret volume refresh timing.

portal init-certs [flags]

Options

      --cert-dir string         local path to mirror cert material to (typically a shared emptyDir) (default "/etc/portal/certs")
      --dns strings             additional DNS SANs to include on the leaf certificate
  -h, --help                    help for init-certs
      --kubeconfig string       kubeconfig path (defaults to in-cluster)
      --namespace string        namespace containing the TLS Secret (default "portal-system")
      --secret string           name of the kubernetes.io/tls Secret to read/upsert (default "portal-webhook-cert")
      --service string          Service name; DNS SANs are derived as <svc>.<ns>.svc, <svc>.<ns>.svc.cluster.local (default "portal")
      --webhook-config string   name of the ValidatingWebhookConfiguration to inject caBundle into (default "portal")

portal migrate-rules

portal migrate-rules

Convert podwatcher-poc SpEL rules into Portal expr-lang rules

Synopsis

Rewrites SpEL→expr-lang differences ({...}.contains(x) → x in [...], .contains('y') → 'y' in ..., filter.namespace → match.namespaces) and emits either one PortalClusterRule manifest per rule (--format=cr, default) or folder-format rule YAML (--format=folder). Idempotent on Portal-format input.

portal migrate-rules [folder] [flags]

Options

      --dry-run         print rewritten content to stdout instead of writing
      --format string   output format: cr | folder (default "cr")
  -h, --help            help for migrate-rules
  -o, --output string   output directory (default: <input>-portal)
