Install software packages required for setting up local development environment in your macOS.

Now to run/execute these scripts you will have to install python in your local computer, again, how will you do that? If you are a mac user, you can use Homebrew. Homebrew is a software package manager for Mac OS which can be used to install required packages, libraries etc to setup your local development requirements.Īnother example, if you decide to learn Python, how will you do that? You will use online tutorials to learn the basics of the language and then practice by creating small programs/scripts in python. Also during development, you will have to install these packages in your local computer too. For example, if you develop a web application in Java using Jax-RS API like: Jersey, RESTeasy etc for REST services, then to run this software you must install Java and the other libraries/APIs used on the server. HelloWorld.When we develop a production software(like, eCommerce website, or an SaaS) it's never just one programming language that satisfies all the requirements, and we end up using various libraries and software packages, which we must install on our server for the software to run.

We are mapping the local directory with the directory: /usr/src/myapp inside the containerĬreate a docker-compose.yml file: version: '2'.

Here we are specifying the Java container running version 8 of the SDK ( java:8 – to use Java 7, you could just specify: java:7).

Project dependencies are installed within the container – so if you mess up your config you can simply nuke the container and start again.

Very easy to switch to different versions of Java by simply changing the tag on the container.

No need to set up any version of Java on your local machine (you’ll just run Java within a container which you pull from Docker Hub).

You can simply run your application within the official JDK container – meaning that you don’t have to worry about getting everything set up on your local machine (or worry about running multiple different versions of the JDK for different apps etc)Īlthough this might not help you with your current installation issues, it is a solution which means you can side-step the minefield of issues related with trying to get Java running correctly on your dev machine! An option that I am starting to really like for running applications on my local computer is to use Docker.
