This container is made for getting real world certificates for your kubernetes cluster.
The assumption is that you can point the DNS name to the container from outside. This is by default given for IPv6 only kubernetes services.
- Set the environment variable DOMAIN to specify the domain for which to get a certificate
- Set the environment variable EMAIL (this is where letsencrypt sends warnings to)
- Set the environment variable STAGING to "no" if you want to have proper certificates - this is to prevent you from asking the real letsencrypt service accidently by default
- By default the container allows world read access to the certificates, so that non-root users can access the certificates. Set the LEAVE_PERMISSIONS_AS_IS environment variable to instruct the container not to change permissions
- If you setup the variable NGINX to any value, the container will start nginx and reload after trying to renew the certificate
docker run -e DOMAIN=example.com \ -e EMAILfirstname.lastname@example.org \ ungleich/ungleich-certbot
docker run -e DOMAIN=example.com \ -e EMAILemail@example.com \ -e NGINX=yes \ -e STAGING=no \ ungleich/ungleich-certbot
you will get a proper, real world usable nginx server. Inject the nginx configuration by meains of a volume to /etc/nginx/conf.d
Exiting after getting the certificate
By default, the container will stay alive and try to renew the
certificate every 86400 seconds. If you set the environment variable
ONLYGETCERT, then it will only get the certificates and exit.
Only renewing the certificate
If you only want to trigger renewing existing certificates and skip
getting the certificates initially, you can set the variable
RENEWCERTSONCE, then it will only renew all certificates and exit.
ONLYRENEWCERTSis set, only the reguler renew loop will run.
ONLYRENEWCERTSONCEis set, renew will be run once and then the container exits
If you want to keep / use your certificates, you are advised to create a volume below /etc/letsencrypt.
