A fast and intuitive Kubernetes context and namespace switcher for Fish shell.

• 🚀 Fast context switching with interactive selection using fzf
• 🎯 Namespace management with fuzzy search
• 📁 Multiple kubeconfig support - automatically discovers configs in ~/.kube/config and ~/.kube/configs/
• 🔍 Context info display - shows current context, namespace, and kubeconfig path
• ⚡ Tab completion for contexts and namespaces
• 🎨 Syntax highlighting in fzf previews using bat

Install using Fisher:

fisher install aohoyd/kswitch

This plugin requires the following tools to be installed:

• kubectl - Kubernetes command-line tool
• fzf - Fuzzy finder for interactive selection
• yq - YAML processor for parsing kubeconfig files
• fd - Fast file finder for discovering kubeconfig files
• bat - Syntax highlighter for fzf previews (optional but recommended)

Switch between Kubernetes contexts with optional namespace specification.

# Interactive context selection with fzf
ks

# Switch to specific context
ks my-context

# Switch to context and set namespace
ks my-context my-namespace

# Launch interactive context selector
ks

# Switch to production context
ks prod-cluster

# Switch to staging context and set namespace to monitoring
ks staging-cluster monitoring

Switch namespaces within the current context.

# Interactive namespace selection with fzf
kns

# Switch to specific namespace
kns my-namespace

# Launch interactive namespace selector
kns

# Switch to kube-system namespace
kns kube-system

# Switch to default namespace
kns default

Display current Kubernetes context information.

ksi

Current KUBECONFIG: /home/user/.kube/configs/prod-cluster.yaml
Current context: prod-cluster
Current namespace: monitoring

The plugin automatically discovers kubeconfig files from:

1. ~/.kube/config (default kubectl config)
2. All files in ~/.kube/configs/ directory

~/.kube/
├── config                    # Default kubectl config
└── configs/
    ├── prod-cluster.yaml
    ├── staging-cluster.yaml
    └── dev-cluster.yaml

The plugin provides intelligent tab completion:

• ks: Completes with available contexts, then namespaces
• kns: Completes with available namespaces

Both ks and kns support interactive mode when called without arguments:

• Context selection: Shows all available contexts from all kubeconfig files with file preview
• Namespace selection: Shows all namespaces in the current context
• Use arrow keys or type to filter results
• Press Enter to select, Escape to cancel

The plugin sets the following environment variable:

• KUBECONFIG: Points to the currently active kubeconfig file

If you see "No contexts found in kubeconfig files":

1. Ensure you have kubeconfig files in ~/.kube/config or ~/.kube/configs/
2. Verify your kubeconfig files are valid YAML
3. Check that contexts are properly defined in your kubeconfig files

Ensure all prerequisites are installed:

# Check if required tools are available
which kubectl fzf yq fd bat

Ensure your kubeconfig files have proper read permissions:

chmod 600 ~/.kube/config ~/.kube/configs/*
