I'm running into a bit of a snag with my Dagger setup and hoping someone can help me out quickly. I have both Docker and nerdctl installed, and I'd like to configure the Dagger engine to always try using nerdctl first for my CI/CD pipelines and workflows. If, and only if, nerdctl isn't available or fails, I want it to fall back to Docker. I've been searching the docs and community, but haven't found a clear solution. This is blocking my progress, so any insights or pointers would be hugely appreciated! Thanks in advance!
#Dagger Engine: Prioritizing nerdctl over Docker (with fallback) - Need ASAP!

👋 @verbal vector I took a quick look at the code base and it looks like docker is hardcoded (could be wrong). One thing you could potentially do is solve this with a function and alias in your shell.
- Add the your shell profile
dockercmd() { command -v nerdctl >/dev/null && nerdctl "$@" || command docker "$@"; }
- Create your alias
alias docker=dockercmd
Can you try that and let me know it that works for you?
