How do I upgrade the runner size from micro to medium?

[thiagovilla]

I need curl and the first time act prompted I went for the micro image (node:16-buster-slim), but now need to upgrade to medium (catthehacker/act-node:latest). Any kind soul?

You can update the .actrc file in your home directory (or remove the file).
Or to play around with the options define your runner image like this:
