| SSL Certificate Option | |
| There are many ways to obtain an SSL certificate. An easy and cheap way is to use LetsEncrypt. Setting up LetsEncrypt for a server that uses port 80 for a webserver is extremely easy. Since the Coturn server does use port 80, a manual request with a DNS challenge is easiest: | |
| Install CertBot | |
| sudo snap install core; sudo snap refresh core | |
| sudo snap install --classic certbot | |
| sudo ln -s /snap/bin/certbot /usr/bin/certbot | |
| Request the certificate |

Deploy a web app on a dedicated server with Kamal
This gist is still a draft. At the moment it is not functional: see basecamp/kamal#257
Kamal was designed with 1 service = 1 droplet/VPS in mind.
But I'm cheap and I want to be able to deploy multiple demo/poc apps apps on my $20/month dedicated server.
What the hell, I'll even host my private container registry on it.

Ubuntu: Bash history search, partial + up-arrow
Both methods below are almost equivalent, it just depends on which file you want to edit. I'd recommend .bashrc myself, as it doesn't involve editing a local copy of a system file.
If you experience any problems with this, please comment below so that it can be fixed.
- Edit
~/.bashrcwith this command:
gedit ~/.bashrc
