HTTPS SSL Task 0-world_wide_web Configure your domain zone so that the subdomain www points to your load-balancer IP (lb-01). Let’s also add other subdomains to make our life easier, and write a Bash script that will display information about subdomains.

Requirements:

Add the subdomain www to your domain, point it to your lb-01 IP (your domain name might be configured with default subdomains, feel free to remove them) Add the subdomain lb-01 to your domain, point it to your lb-01 IP Add the subdomain web-01 to your domain, point it to your web-01 IP Add the subdomain web-02 to your domain, point it to your web-02 IP Your Bash script must accept 2 arguments: domain: type: string what: domain name to audit mandatory: yes subdomain: type: string what: specific subdomain to audit mandatory: no Output: The subdomain [SUB_DOMAIN] is a [RECORD_TYPE] record and points to [DESTINATION] When only the parameter domain is provided, display information for its subdomains www, lb-01, web-01 and web-02 - in this specific order When passing domain and subdomain parameters, display information for the specified subdomain Ignore shellcheck case SC2086 Must use: awk at least one Bash function

Task 1-haproxy_ssl_termination “Terminating SSL on HAproxy” means that HAproxy is configured to handle encrypted traffic, unencrypt it and pass it on to its destination.

Create a certificate using certbot and configure HAproxy to accept encrypted traffic for your subdomain www..

Requirements:

HAproxy must be listening on port TCP 443 HAproxy must be accepting SSL traffic HAproxy must serve encrypted traffic that will return the / of your web server When querying the root of your domain name, the page returned must contain Holberton School Share your HAproxy config as an answer file (/etc/haproxy/haproxy.cfg) The file 1-haproxy_ssl_termination must be your HAproxy configuration file

Make sure to install HAproxy 1.5 or higher, SSL termination is not available before v1.5.

Task 100-redirect_http_to_http A good habit is to enforce HTTPS traffic so that no unencrypted traffic is possible. Configure HAproxy to automatically redirect HTTP traffic to HTTPS.

Requirements:

This should be transparent to the user HAproxy should return a 301 HAproxy should redirect HTTP traffic to HTTPS Share your HAproxy config as an answer file (/etc/haproxy/haproxy.cfg)
