Enable SSH section not appear on version 2.0

I’d like to use ssh to build VM, and follow with this instruction:
https://circleci.com/docs/2.0/ssh-access-jobs/

But “Enable SSH” section not appear.
Is there anything other setting required?

I set .circleci/config.yml as following.

version: 2
jobs:
build:
working_directory: ~/data/***/current
docker:
- image: circleci/php:5.6.30-fpm-browsers
environment:
PHP_ENV: test
steps:
- checkout
- run:
name: Composer Install
command: |
php -r "copy(‘https://getcomposer.org/installer’, ‘composer-setup.php’);"
php -r "if (hash_file(‘SHA384’, ‘composer-setup.php’) === ‘669656bab3166a7aff8a7506b8cb2d1c292f042046c5a994c43155c0be6190fa0355160742ab2e1c88d40d5be660b410’) { echo ‘Installer verified’; } else { echo ‘Installer corrupt’; unlink(‘composer-setup.php’); } echo PHP_EOL;"
php composer-setup.php
php -r “unlink(‘composer-setup.php’);”
./composer.phar self-update
- run:
name: Install PHP package
command: |
./composer.phar install -n
- run: echo “hello world2”

Regards,
