Thanks. Was wondering if there is a utility method which already does that.

That's a good point. Searching the internet I did not find any lib that does this. I was also supprised the slice type has no internal method since this is such a common task. Searching the skaffold source code for for i, j and for for .*,.*:=.*,len does not give any results.
The golang completion on the other side provides a slice.reverse! method which automatically creates the for loop. Maybe that's why there is no lib or function.
I can put such a function somewhere in the skaffold source code if you wish. I need help finding the location where such a function would be placed best.

You can write this function here:

Looking into this now.

@gsquared94 I tried adding a function to the file you suggested. However when I did this, I created a dependency lopp between util.go and deploy.go.
I also tried creating a generic slice reverse function in utils but since the go.mod file says to use at least go 1.17, I could not use generics.
In the end I added it to DeployMux since this is the only place using this function for now.

Sorry for pushing again. I've rebased to main, fixed the linting erros and added a file to the gitignore for asdf. |
