While I haven’t done too much with Serverless Framework and Functions as a Service (Faas) recently, I did in the past and it isn’t something that I’ve forgotten. In the past I demonstrated how to deploy Node.js functions to Amazon Web Services (AWS) Lambda that contain native dependencies. While not a necessity for all Lambda functions, it is for functions that use libraries for specific operating systems and architectures. For example, my previous article titled, Use AWS Lambda and API Gateway with Node.js and Couchbase NoSQL, fell into this situation. Making use of an EC2 instance or a Docker container with Amazon Linux will help most of the time, but there are scenarios where a little bit extra must be done to accomplish the task.
In certain circumstances everything may package and deploy correctly, but still throw errors. For example, a common error is around libstdc++ and a version of GLIBCXX not being found.
In this tutorial we’re going to see how to resolve library errors that might not be caught in a typical packaging and deployment scenario with Serverless Framework and AWS Lambda.Read More
MongoDB is one of the most popular NoSQL databases on the market right now and is used heavily with Node.js development in particular. So what if you wanted to give MongoDB a spin and see what it’s all about?
There are plenty of deployment options when it comes to using MongoDB. For example, I had recently written a tutorial titled, Developing a RESTful API with Node.js and MongoDB Atlas which focused on the MongoDB cloud solution called Atlas. However, you can also install MongoDB on premise using multiple options.
In this tutorial we’re going to focus on using Docker to deploy MongoDB as a container and interact with it with the shell client.Read More
I know I’ve mentioned this before, but I’ve recently started to get serious about my content production and deployment approach on The Polyglot Developer. My goal is to be able to write my tutorials in Markdown, push to GitLab, and have it automatically deployed as a Docker container on my production server. Being able to automate things and take advantage of Docker will definitely improve my productivity in the long term.
So I’ve been playing around with tools on the subject, more specifically GitLab, because that is what I’m using to save a history of the blog. GitLab is a source code repository, but also a whole lot more given its ability to do continuous integration, continuous deployment, and work with Docker directly.
We’re going to take a look at installing GitLab and Docker on a Raspberry Pi, then configuring a GitLab CI Runner to take control of our continuous integration process every time we push some code. While it might sound easy, there are some certain things that aren’t so obvious in the setup and configuration.Read More
I’ve been in the web game for quite some time and have my fair share of web server software. I’ve used Microsoft’s Internet Information Services (IIS), Apache httpd, as well as NGINX, and while they all thrive in their own ways, they’ve been overkill for most of my use cases. This is where Caddy comes in, a lightweight alternative to these seasoned, but often heavy web servers.
We’re going to see how to use Caddy and learn why it is so powerful while using minimal effort on a developer operations side.Read More
If you’ve ever worked with Docker containers you’ve probably been exposed to them being stateless, meaning when a container is destroyed, all record of it is lost including any files it might have created. Not great if you’re working with say a database, correct? However, let’s look at this from a different angle. Let’s say you are deploying a web application that requires some configuration. Depending on how you’ve developed it, the configuration could be controlled via a file or via environment variables. How do you accommodate this with Docker container deployments when you don’t want these configurations baked into the image?
We’re going to see how to work with volume mapping between container and host machines as well as passing environment variables at container deployment with Docker.Read More
I am pleased to announce that Containerization with Docker by Example, a course I’ve been working on for a while, has been published to the popular Udemy education network.
This course, is the fifth course that I’ve released and the first that hasn’t been on the topic of mobile application development.Read More
So you’ve been doing a lot of research around the blockchain and the various cryptocurrencies. Don’t worry, I’ve been doing a lot of the same research. There is so much in the news and on social media around this subject, it would be a good idea to educate yourself.
When it comes to cryptocurrencies, there are a lot of people trying to mine it rather than buy it. Depending on the type of currency, it could be near impossible to mine or very easy. Take Bitcoin for example. Bitcoin is one of the most difficult coins to mine, while others such as DigiByte are much easier. That’s not to say the easier coins won’t become more difficult in the future.
So how do you get started with mining?
I use a Mac. If you’re a Mac owner and you try to find a mining tool online, you’re going to struggle because most are for Windows or Linux. We’re going to see how to leverage Docker to mine via a Linux container on any platform.Read More
