Introduction # We have previously seen how to set up a GitHub to Jenkins pipeline with webhooks, this time we are going to continue on that lesson and learn how to configure Jenkins to build docker images and push Docker images to DockerHub.
We’ll also see how to create images for both arm64 as well as amd64 architectures machines. Keep on reading.
Introduction # In a typical CI/CD pipeline, what happens is when you push your code to a code repository (remote) like GitHub/GitLab/BitBucket, an event is triggered by the git host provider. This trigger is known as WebHook. This webhook can be used by some third-party service to provide an array of integrations. Do you want to tweet on every git push? You can do that.
You can’t think of deploying your application to production without testing it.
Neither you can manage a large codebase with confidence without it.
Let us go through some basics of unit testing in golang.
This post is structured in the following manner:
unit testing basics in golang (jump) inbuilt code coverage command understanding subtests and helper function (jump) Travis CI integration (jump) running test against multiple version of go Please connect with me on LinkedIn and let’s get started.
