Preparing a Github/Gitlab Development Bastion Server

So you are looking to use github / gitlab to manage your infrastructure and development. To do this effectively you will need to prepare your environment. Here is an example.

This is for our ansible playbook.

Install Required Dependencies

yum update -y
yum install -y vim git ansible tree fail2ban

Add user for repo

useradd -m -G wheel osan
passwd osan

Secure SSH by disabling root login and changing SSH port

sed 's/#PermitRootLogin yes/PermitRootLogin no/g;s/#Port 22/Port 222/g' -i /etc/ssh/sshd_config
firewall-cmd --add-port=666/tcp --permanent
firewall-cmd --reload
systemctl restart sshd.service

Generate key for osan user

su - osan
ssh-keygen -f ~/.ssh/id_rsa -t rsa -N ''

Output the key you generated

cat ~/.ssh/

The next step is adding your SSH key above to the ‘profiles’ section of your gitlab/github user. Find this in my profile, under ‘SSH KEYS’.
