Apple M1 Users

The Apple M1 and M2 are ARM based. OPS is built for users primarily deploying to x86 based servers. While you can certainly run ARM builds with Nanos and OPS be aware that if you are trying to run x86 builds (the default) on ARM based M1s you won't be able to use hardware acceleration.

Build a bootable image

ops build <app>

Package and run

ops run <app>
# or
ops run -p <port> <app>

Using a config file

ops run -p <port> -c <file> <app>

Example config file

ops config files are plain JSON, below is an example

{
  "Args":["one","two"],
  "Dirs":["myapp/static"]
}

Setup networking

New users wishing to play around in a dev environment are encouraged to use the default user-mode networking. Other production users are encouraged to utilize native cloud builds such as Google Cloud which handle networking for you.

Only advanced/power users should use the bridge networking option.

Reporting Bugs

Feel free to open up a pull request. It's helpful to have your OPS version and the release channel you are using.

Also - if it doesn't work on the main release you can try the nightly - the main release can tail the nightly by many weeks sometimes.

ops version

if you are using a package, get the package hash:

jq '."gnatsd_1.4.1"' ~/.ops/packages/manifest.json

Pull Requests

If you have an idea for a new feature and it might take longer than a few hours or days to do it's worth opening a feature request tkt to ideate it first before jumping into code. There might be someone already working on the feature or plans to do something entirely different.

Builder Design Pattern

What is Builder Design Pattern ? Why we should care about it ?

Starting from **Creational Design Pattern, **so wikipedia says “creational design pattern are design pattern that deals with object creation mechanism, trying to create objects in manner that is suitable to the situation”.

The basic form of object creations could result in design problems and result in complex design problems, so to overcome this problem Creational Design Pattern somehow allows you to create the object.

Builder is one of the** Creational Design Pattern**.

When to consider the Builder Design Pattern ?

Builder is useful when you need to do lot of things to build an Object. Let’s imagine DOM (Document Object Model), so if we need to create the DOM, We could have to do lot of things, appending plenty of nodes and attaching attributes to them. We could also imagine about the huge XML Object creation where we will have to do lot of work to create the Object. A Factory is used basically when we could create the entire object in one shot.

As **Joshua Bloch (**He led the Design of the many library Java Collections Framework and many more) – “Builder Pattern is good choice when designing the class whose constructor or static factories would have more than handful of parameters

Builder design pattern — java

Definition of Builder Pattern

The builder pattern is a design pattern that allows for the step-by-step creation of complex objects using the correct sequence of actions. The construction is controlled by a director object that only needs to know the type of object it is to create.

Where to use the builder pattern?

When you have a simple object, this pattern is not very useful, but when you begin to have a more complex object and want to have a clear code you can use it without hesitation
