# So we get the live image or a current image from Python, and

There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.

All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.

  1. Loop variables are scoped outside the loop.

What do these lines do? Make predictions and then scroll down.

Just a clever way to set an RDS master password with Terraform and Ansible to prevent the password from being stored in plain text
resource "aws_db_instance" "core" {
username = "postgres"
password = "changeme"
...
}
resource "null_resource" "master_password" {
triggers {
db_host = "${aws_db_instance.address}"
}
