Helm - zsh: no matches found: imagePullSecrets[0].name=regcred

Really waste me minutes to resolve this problem, as I'm not familar with zsh. [] syntax has its meaning in zsh. So there are two simple ways to step aside.

Change to bash

Well, switch to bash by just entering `bash`. And then run you helm install again.

noglob

Or you can use noglob.

noglob helm install --generate-name ./mychart \
  --set imagePullSecrets[0].name=regcred
