NodeBalancer Auto-Renew SSL Lets Encrypt?

I have passed along this feature request on your behalf, but you can always submit feedback using this form if you have other requests in the future.

While I hope we can roll out a more direct way to do this or create a custom guide in the future, I did find some third-party resources that can help you with this, though I haven't tested them:

• GitHub - Let's Encrypt Linode - A user has created this Docker container to help with using Let's Encrypt with NodeBalancers.

• Let’s Encrypt HTTPS + Linode NodeBalancer - This source is a bit old, so you may need to update some commands using our Certbot Guides.

I created an implementation using DNS-01, this doesn't require proxying to the Linode as defined in the "GitHub - Let's Encrypt Linode" link and it's basically just a script that needs to be run on a nanode.

Here's the link if anyone is looking for this in the future

https://github.com/benlabbeus/nodebalancer-ssl

1. Install linode-cli

2. Generate Access Token

3. Setting linode-cli
   $ linode-cli configure

4. Find nodeBalancerId
   $ linode-cli nodebalancers list
   id label
   12345 myNB

5. Find configId of nodeBalancerId
   $ linode-cli nodebalancers configs-list 12345
   id port protocol
   4567 443 https

6. Update certificate of NodeBalancer
   $ linode-cli nodebalancers config-update 12345 4567 --ssl_cert /etc/letsencrypt/live/{your_domain}/fullchain.pem --ssl_key /etc/letsencrypt/live/{your_domain}/privkey.pem

7. Edit crontab to update NodeBalancer after renew Let's Encrypt certifiate

I have written a note in Chinese here:
