Hi Ian,
Hi Ian,
I worked around this for tomcat by using the "--standalone" option
for certbot. That just requires that you have port 80 and 443
(temporarily) open for all while it does the verification. My
Ansible playbook uses
certbot certonly --noninteractive --agree-tos --standalone --email
{{certbot_admin_email}} -d {{inventory_hostname}}
then
openssl pkcs12 -inkey {{certbot_output_dir}}/privkey.pem -in
{{certbot_output_dir}}/fullchain.pem -export -out
{{tomcat_keystore_dir}}/vlibrary.pfx -password pass:{{key_pwd}}
I agree it would be great to have an auto-install certbot setup for
tomcat, though.
