In my previous for Nginx and Nginx Proxy Manager (NPM), I wrote on how to install NPM, but didn’t configure any certificates.

Out of the box Nginx Proxy Manager supports Let’s Encrypt SSL auto creation and renewal.

There is one limitation – you can create certificates only for specific domains/subdomains directly. If you want to create wildcard certificate you will need to use DNS Challenge.

What does that mean? You need to use some DNS server that allows API …

Lately I have started playing with Kubernetes and wanted to expose some of the locally hosted services on internet. The situation is that I want to expose multiple clusters running on separate machines through the same IP address and port. Checking around it seems nginx is the the best option. Keep in mind that even you want to expose just one service it is still good idea to do it through nginx.

I have installed Ubuntu 20.04.3 on Raspberry Pi …

One of the disks got bad sectors and the other one lost it’s superblock. So the array was degradated and the only one “good” disk was with bad sectors. I added a new disk and tried to sync the data but it stucked on 36%. Using tools like “dd” or “ddrescue” didn’t help neither. The “dd” just kept stopping and the “ddrescue” was recovering with 364Bytes/second so …
