TBH, I've never downloaded a Docker image. I rely on Debian; I trust packages from the Debian repository (hell, I'm running their OS, so I already trust them).

TBH, I've never downloaded a Docker image. I rely on Debian; I trust packages from the Debian repository (hell, I'm running their OS, so I already trust them). Software from other sources: not so much. Maybe run it in a VM. Look, I've used such commands myself - once upon a time that was the recommended way to install LetsEncrypt, I think. But I look at the script first.
