You may have noticed that the index.html file was generated, but it only lived inside the Docker container. An ENTRYPOINT allows us to configure a container that will run as an executable. The most important part of our example is the ENTRYPOINT instruction. ![]() How does this work? The Dockerfile that produces the image we used previously can be found below. Running wget inside docker using docker run -rm mwendler/wget Once you have the image you'd like to run, you can run wget using: In this case, we'd like to grab an image that has wget: How did Docker change my workflow? Running wget-like commands on your MacĪs with Homebrew, you can search for Docker images using the Docker CLI too. That can go a long way if you think about setting up new production environments, being on call, or just troubleshooting production issues. I found that the closer one's development machine is to the production environment, the better understanding they'll have of their production systems. Most companies running backend services deploy their artifacts using some kind of containerization technology, most probably Docker. With the help of HyperKit (a hypervisor built on top of the amework in macOS), now we can run Docker natively on macOS.Īs I've started to use Docker more, I've also started to use Homebrew a lot less frequently. While it does not seem a lot, it is far from a great user experience.
