set -e, -u, -o, -x pipefail explanation

set -e, -u, -o, -x pipefail

The set lines

  • These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
  • With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.
  • set -euxo pipefail is short for:
set -e
set -u

How to Setting Up a Comodo SSL Cert

How to Setting Up a Comodo SSL Cert

  • I advice you to buy SSL Certs from officially Comodo only , or some SSL reseller whose you trust.

These are the steps I went through to set up an SSL cert. Purchase the cert

Prior to purchasing a cert, you need to generate a private key, and a CSR file (Certificate Signing Request). You’ll be asked for the content of the CSR file when ordering the certificate:

openssl req -new -newkey rsa:2048 -nodes -keyout example_com.key -out example_com.csr
