Dev Setup

What are some of the setups I need when working with Cloud?

  • Setup ssh to compute/ec2 instance (this could be limited to Ubuntu machines)
  • Setup FTP client to connect your local machine to compute/ec2, using your private ssh key created in step before, in case you want to push/pull files. I use FileZilla.

Cloud GCP Setup

Compute Engines

  • [Imp] If you're like to setup SSH keys globally, navigate to compute -> metadata to add your key there instead.
  • Make sure to always have a right sized machine. Try using micro for small work
  • Always have a default script while setting up a compute engine
Basic Script
sudo apt-get update
sudo apt-get upgrade
Adding dependencies
# more information about processes. Refer: https://hisham.hm/htop/
sudo apt-get install htop
Compute Shell Commands
$ cat /etc/os-release    - Find operating system installed
$ free                   - display free system resources
