To configure serverless to use our local container, we must install another plugin, serverless-dynamodb-local. Lucky for us, Amazon also provides an easy to use Docker image, which we can run along with our serverless application. DynamoDB local is a downloadable version of DynamoDB designed for local development. In this case, how can I run my functions locally? Sure, I can point my Lambda to a Dynamo table in AWS, but this is not always desirable, especially for large teams. For instance, it is typical for a Lambda function in AWS to integrate with DynamoDB. npx serverless offlineĪs exciting as building serverless functions is, these functions seldom live in a vacuum. If we open the terminal, we will notice it is a bash shell! As before, we can run our application with the following command.

Executing the ‘Remote-Containers: Reopen in Container’ command will reopen Visual Studio Code within our new container. Once complete, we have all the required files for running a development container. All we have to do is run the `Remote-Containers: Add Development Container Configuration Files’ command as shown below. Visual Studio Code walks us through creating the required files for running in a container. Sorry guys, no more “it works on my machine” excuses. Using a remote container allows us to do our development completely within a Docker container. Aside from being an excellent IDE, it comes with a handy feature called Remote Containers. I use Visual Studio Code for the majority of my development work. Now that we have our serverless solution running locally, let’s start incorporating Docker into the mix. custom:įor further reading, view the GitHub readme here.

Configuration changes are common to update the default behavior, such as the hosting port. plugins:Īn additional section can be added to the serverless.yml file to configure the plugin. Next, the plugin needs to be declared in the serverless.yml configuration file. First, we need to install the plugin with npm. By simulating AWS Lambda functions and API Gateway, developers can quickly run and debug their serverless applications entirely on their own machine!Īs is with most plugins, installation is very straight forward. The most popular of these is the serverless-offline plugin, which allows developers to run serverless functions behind a local HTTP server. Coupling this with its strong community support provides developers with plugins for the majority of their development needs. One of my favorite aspects of the serverless framework is the extensibility through its plugin architecture. If you are new to the serverless framework, please take a look at their getting started guide and AWS provider documentation. That being said, there is a wealth of information on their website. The serverless framework is a topic in itself so, we will not go into details in this article. Next, type serverless, and a wizard will guide you through creating your new project.

Strong community backing with plugins galore.

Support for all major cloud providers such as Azure, AWS, and GCP.

Not being native to Azure or AWS, the serverless framework has the following benefits. I tend to gravitate towards the serverless framework. Several frameworks are available to create, build, and deploy serverless functions. So, where does Docker come into play? In this article, we will discuss how you can use Docker and the serverless framework to supplement your local development experience. You create a function in your favorite language and ship it while effectively all administration is handled by your cloud provider. One of the key benefits of “Function as a Service” (FaaS) or “serverless” offerings is developers do not have to worry about infrastructural concerns such as Virtual Machines, Containers, and the like.

If you have experience with Azure Functions or AWS Lambdas, then the title may sound a bit like an oxymoron.
