Should I get a credit card now?

Hi all,

I am 21 years old fresh out of college with a shitty part time job at a retail store that unfortunately doesn't give me too many hours. I want to start building credit so i can eventually move out. I only have a bank account with chase with around $1700 saved up. I haven't received my first pay check yet from this current job that I started on July 4th.

I'm not sure what to do and what credit card I should apply for. I only would use the credit card for necessities, such as gas. Would it be okay if I applied for a credit card now and only use it on gas since I don't have consistent hours with my job at the moment? And which card should I apply for?

Thanks
