Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

How to use SchemaSpy to generate the db schema diagram for a PostgreSQL database

SchemaSpy is a neat tool to produce visual diagrams for most relational databases.

Here's how to use it to generate schema relationship diagrams for PostgreSQL databases:

  1. Download the jar file from here (the current version is v6.1.0)

  2. Get the PostgreSQL JDBC driver (unless your installed version of java is really old, use the latest JDBC4 jar file)

  3. Run the command against an existing database. For most databases, the schema (-s option) we are interested in is the public one:

Global gitignore

There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file:

  • Create a file called .gitignore in your home directory and add any filepath patterns you want to ignore.
  • Tell git where your global gitignore file is.

Note: The specific name and path you choose aren't important as long as you configure git to find it, as shown below. You could substitute .config/git/ignore for .gitignore in your home directory, if you prefer.
