How I made space on Digital Ocean droplet

Submitted by uday on April 20, 2022 - 7:30pm

The droplet on Digital Ocean for my Rails project did not have any space left.

Here is how I created space by deleting files.

1. Login using SSH and check available space using $df -h

2. Check disk usage using du command.

$du -h | sort -h

This will list the directories showing the biggest size at the bottom.

I noticed that ./project/shared/log folder was consuming 3.3GB space.

3. In another terminal window, I opened sftp session.

4. sftp>cd project/shared/log

How to add bootstrap 5 to an existing Rails 7 app

Submitted by uday on January 16, 2022 - 2:11pm

I tried to install bootstrap 5 in existing Rails 7 application. The keyword "existing" is very important because for a new application you can try following.

$rails new app-name -j esbuild --css cssbundling-rails (Note: Do NOT miss -j flag to install JavaScript first. In one Youtube video, it was skipped, however it did NOT work for me for a test app I tried to install. Not sure why.)

Recently, I could not boot into my laptop because the laptop ran out of space. No attempt to resize sda was successful. Since the disk was encrypted, I could not even access my data files.

0. Create Ubuntu iso image CD and install Ubuntu 20.04 onto laptop.
