Docker compose as a systemd unit

Create file /etc/systemd/system/[email protected]. SystemD calling binaries using an absolute path. In my case is prefixed by /usr/local/bin, you should use paths specific for your environment.

Mistakes to Avoid: Docker Antipatterns

Whichever route you take to implementing containers, you’ll want to steer clear of common pitfalls that can undermine the efficiency of your Docker stack.

Don’t run too many processes inside a single container

The beauty of containers—and an advantage of containers over virtual machines—is that it is easy to make multiple containers interact with one another in order to compose a complete application. There is no need to run a full application inside a single container. Instead, break your application down as much as possible into discrete services, and distribute services across multiple containers. This maximizes flexibility and reliability.

Don’t install operating systems inside Docker containers

It is possible to install a complete Linux operating system inside a container. In most cases, however, this is not necessary. If your goal is to host just a single application or part of an application in the container, you need to install only the essential

Do not use forEach with async-await

TLDR: Use for...of instead of forEach() in asynchronous code.

For legacy browsers, use for(...;...;...) or [].reduce()

To execute the promises in parallel, use Promise.all([].map(...))

The problem

This defines the schema for .NET Core's runtimeconfig.json file.

Usage in an editor

Using Visual Studio, you can get auto-completion if you import the schema in your .JSON file like this:

{
  "$schema": "https://gist.githubusercontent.com/natemcmaster/0bdee16450f8ec1823f2c11af880ceeb/raw/runtimeconfig.template.schema.json"
}

	.SYNOPSIS
	Locates Java versions and optionally sets JAVA_HOME and JRE_HOME.
	.DESCRIPTION

	If run with no options, the first Java found is printed on the console.
	.PARAMETER Vendor
	Selects Java vendor, currently supports Oracle, OpenJDK and IBM. Defaults to Any.
	.PARAMETER Architecture
	What processor architecture to match. Valid options are 32, 64, Match and All. Match detects what integer size is used for the PowerShell process, and matches the architecture. If Wow64 is available, 64 bit versions of Java are selected first.
