Yes indeed, It's possible for me to grow carrots and onions, in a pot, in my hot dry climate in SoCal.
I harvested a sample to check on progress. Grown from seed sown in late spring. Large pot, draped netting over seedlings to protect from birds, basic potting soil, watered gently & throughly, spoke to them a lot to encourage
Also, as carrots gained more leaf, I harvested some of those greens for house rabbit
Cycles and seasons, right?
