PostgreSQL index naming convention to remember

The standard names for indexes in PostgreSQL are:

{tablename}_{columnname(s)}_{suffix}

where the suffix is one of the following:

  • pkey for a Primary Key constraint;
  • key for a Unique constraint;
  • excl for an Exclusion constraint;
  • idx for any other kind of index;

Instructions on signing VirtualBox and VMware modules for Secure Boot

Signing VirtualBox & VMware modules

Source

Creating a key

You can change "MOK".priv/.der to any desired name; "CN=" MUST hold your username, signing the modules may not work otherwise (on shim, possibly due to a bug).

$ openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=John Doe/"

Steps to deploy Route Reflectors

Steps to deploy Route Reflector on UCP 3.0

    curl -O -L https://github.com/projectcalico/calicoctl/releases/download/v3.1.1/calicoctl
chmod +x calicoctl
