Assignment

for https://vkb.udemy.com/course/learn-ansible-advanced/

Requirement

4 hosts in virtualboxes with centos 8 (image from osboxes.org)
3 targethosts with IP in inventory.txt, grouped to two http hosts and one db host

Usage

# shell on ansible-controller
# install ssh-key to all target
ssh-keygen
ssh-copy-id {ip-target1}
ssh-copy-id {ip-target2}
ssh-copy-id {ip-target3}

# install ansible
dnf install -y epel-release git
dnf install -y ansible

# clone repo
git clone git@github.com:cyper85/advanced-ansible-course.git

Change the IP-Addresses in inventory.txt to the correct ones Change the DB-IP-Address in /vars/http_server.yml

cd ~/advanced-ansible-course
ansible-playbook install-playbook.yml -i inventory.txt --extra-vars "ansible_sudo_pass=osboxes.org" --ask-vault-pass

vault-password is osboxes.org

Server are started on both http-targets.

Loadbalancer

I installed the loadbalancer on the ansible-controller-host

ansible-playbook setup-loadbalancer.yml --extra-vars "ansible_sudo_pass=osboxes.org  --ask-vault-pass"

At the end, you can call http://{ansible-controller-host-ip}:80 and see on of the http_server.

TODO And under http://{ansible-controller-host-ip}:8080 you'll find the haproxy-stats-page.
