Se você encontrar esse erro:
Failed executing CMD: sudo su - minion -c cd /home/minion/projects/53aeff131770496802ad9313/code && /home/minion/projects/53aeff131770496802ad9313/code/run_script 2>&1

ActiveRecord::StatementInvalid:
Mysql2::Error: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation =:
Isso vai resolver:
# shippable.yml
before_script:
- mysql -e 'create database shippable_test CHARACTER SET utf8 COLLATE utf8_general_ci;'
