Build Status

Details

Bash has the programmable completion feature which permits typing a partial command, then pressing the [TAB] key to auto-complete the command sequence.To use the feature, you need to write a completion script and place it in /etc/bash_completion.d folder (docs, tutorial). Fortunately,

kubectl
comes with a command to generate completion script (kubectl completion). The script works extremely well, but slow, because each time you hit [TAB] it sends a request to Kubernetes API Server. If your server is on a different continent you might wait for up to 2 seconds. To reduce the delay,
kubemrr
keeps names of resources locally. See how to make a completion script which talks to
kubemrr
instead of real Kubernetes API server in the example below.

Example

To start watching servers, give context names from your kubeconfig file:

kubemrr watch dev prod

To make completion script that talks to

kubemrr
shell:
alias kus='kubectl --context us'
kubemrr completion bash --kubectl-alias=kus > kus
sudo cp kus /etc/bash_completion.d

Note that you need to have bash completion installed. It shoud be available on a Linux distribution. On a Mac, install with

brew install bash-completion
.

Replace

bash
with
zsh
in the above command to generate completion script for
zsh
shell.

To test it:

source kus
kus get po [TAB][TAB]
kus get svc [TAB][TAB]
kus get deployments [TAB][TAB]
kus get configmaps [TAB][TAB]
kus get namespaces [TAB][TAB]
kus get nodes [TAB][TAB]

To make completion script that talks to

kubemrr
that is running on different host (use IP to save time on name resolution):
kubemrr completion bash --address=10.5.1.6 --kubectl-alias=kus > kus
