Let's Encrypt wildcard certificates - tutorial

Hey guys I just created one, so ff you still need that …

• Get certbot greater than 0.23 (I used 0.25 from docker-hub official certbot)
• Mount /etc/letsencrypt dir [Only for docker]
• Run certbot certonly --server https://acme-v02.api.letsencrypt.org/directory --agree-tos --manual --preferred-challenges dns -d 'DOMAIN,*.DOMAIN'
• You’ll be asked to agree about public IP
• Certbot will ask you to put TXT dns registries in your DNS. In webroot (for simple domains you have to put a file in your nginx/apache server, but now for wildcards you have to really put TXT dns. like:
• Type | hostname | token | TTL
• TXT | _acme-challenge.DOMAIN |90lOhB2V......wqY | 1
• You have to wait a few seconds (and test with $ nslookup -q=txt _acme-challenge.DOMAIN)
• Then you just hit enter a few times and you will get your cert :D
• Enjoy

I hope that micro-guide can help you =) Cheers
