Note
We have to follow the Run List condition,i.e we need to take one one recipe from both cookbook.
Now,I am taking ktexperts-apache-recipe.rb from ktexperts-apache-cookbook and ktexperts-sample-recipe.rb from ktexperts-apache-cookbook.
Modify the recipe”ktexperts-apache-recipe.rb”

As of now we have seen Run List and include_recipe
Run List —–> one recipe from one cookbook
include_recipe —–> All recipes must be same cookbook.
Combine Run List and include-_recipe ——–> All recipes from from different cookbook.
we can run any number of recipes from any number of cookbook.
Note
Here,I am modifying the recipe.
we can modify if required.
Execute the multiple recipes from multiple cookbook
I didn’t do any changes in the all recipes that’s why it’s showing 0/5 resources.
