I am using zsh with oh-my-zsh and I put an entry into my ~/.zshrc to have a shortcut for the option --dry-run=client -o yaml
as a variable and be faster for generating yaml files with imperative commands
when I enter for example kubectl run test-pod --image=nginx $do
I get the error error: Invalid dry-run value (client -o yaml). Must be "none", "server", or "client".
as if the equal operator has not been read.
it works fine with bash
I am using kubectl plugin for auto-completion
my zshrc:
plugins=(git docker kubectl docker-compose ansible zsh-autosuggestions zsh-syntax-highlighting sudo terraform zsh-completions)
alias ls="exa --icons --group-directories-first"
alias ls -l="exa --icons --group-directories-first -lg"
alias ll="exa --icons --group-directories-first -lg"
alias cat="ccat --bg=dark -G Plaintext=brown -G Punctuation=white"
export PATH=$PATH:/usr/local/go/bin
# create yaml on-the-fly faster
export do='--dry-run=client -o yaml'
my bashrc:
# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if ! shopt -oq posix; then
if [ -f /usr/share/bash-completion/bash_completion ]; then
. /usr/share/bash-completion/bash_completion
elif [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
fi
export do='--dry-run=client -o yaml'
and when I execute the command it works fine
$ kubectl run test-pod --image=nginx $do
apiVersion: v1
kind: Pod
metadata:
creationTimestamp: null

run: test-pod
name: test-pod

As @Gairfowl metioned The distinction is that word splitting for unquoted parameter expansions is not performed by zsh (by default).
By enabling the SH WORD SPLIT option or by using the = flag on a specific expansion, you can enable "regular" word splitting same as bash. To do that you need to follow this syntax
kubectl run test-pod --image=nginx ${=do}
or
kubectl run test-pod --image=nginx ${do}
In case if these two dont work try to use the setopt
setopt SH_WORD_SPLIT
kubectl run test-pod --image=nginx $do
