If you have fuzzy finder, use the following functions to filter for multiple kubernetes services and port-foward using a stable and unique local port.

Put the code below into your ~/.bashrc (or any place you source from)

kpfz ()
{ 
    local svcs=$(FZF_DEFAULT_COMMAND="command kubectl get svc -o json $_NS | svc-ports" fzf -m --ansi --no-preview -1 --exact --select-1 --query="$@");
    if [ -z "$svcs" ]; then
 return;
