When I'm developing an application I usually need to start it up, check what's running, and execute some bash commands. I find myself using these three the most often: Kill a currently running container using its id. docker-composeĭocker Compose simplifies the process of coordinating multiple containers and lets us do so with one YAML file. For instance, what if we want to get both a PostgreSQL database and a FastAPI backend going?ĭocker provides a handle docker-compose system to help us manage that. But doing that by hand gets tedious when we want to have multiple containers running and communicating simultaneously. It's built on Busybox Linux which is a 2MB distro of Linux, so Alpine is much, much smaller than a standard Ubuntu image (on the order of 100s of MBs).Īll we need to do is tell Docker to create a container based on this file, and we'll be good to go.

Alpine is just a bare bones alternative to Ubuntu. CMD executes a single command in the shell of our new container.Ī note on why we're using the Alpine image.backend takes everything in our local working directory and copies it into the /backend directory in our container. WORKDIR works as if you had cd'd into that directory, so now all paths are relative to that.We're pullimg the Alpine 3.8.1 image found here. The FROM command specifies what image to pull from Docker Hub.

Each new line in a Dockerfile is an instruction on how to modify a newly created Docker container.Ī quick summary of what's happening here:Įach line starts with a command ( FROM, WORKDIR, COPY, and CMD in this case) followed by the appropriate parameters that tell Docker how to change our container. Using Dockerĭocker has a special file called a Dockerfile which allows you to outline how a container will be built. Be warned that it's going to eat up a lot of memory (like 2GBs) running regularly. Whenever we want want to create a container, we can tell the docker client to pull an image from docker hub, and then use Docker's command-line interface to sping up containers at will. Difference between virtual machines and containers - source googleĭocker provides a desktop client and container engine consisting of a daemon and other utilities to do container management. If you've heard the term Virtual Machine before, this might look familiar to you. Docker can spin up 1000s of containers that all share an underlying operating system, each running their own isolated execution environment. It's a lightweight blueprint that is used to create consistent and predictable computing environments that run on a single machine. An image is just a snapshot of how a container should be created. Containers and Imagesĭocker provides Docker Hub - a resource to source, store, and manage images. TLDR - Docker makes creating, distributing, and running containers easy.
#NOT ENOUGH MEMORY TO START DOCKER DESKTOP SOFTWARE#
The role of Docker is to "package software into standardized units for deveopment, shipment, and deployment." It does that by leveraging two core abstractions - containers and images. What if we wanted Node.js v10.12.1 on one, and an anaconda distribution on another? Postgresql? Add on the postgis extension for our geolocation app? What if we want all of those dependencies to look the same on every machine, every time, and behave consistently across the board? What if we want a cluster of 10 machines all running identical versions of a large number of packages? Now what if we wanted to do that with 30 different machines? Well, then things get interesting.
#NOT ENOUGH MEMORY TO START DOCKER DESKTOP INSTALL#
Have you ever bought a new macbook computer and then had to set up Microsoft Word, download a few printer drivers, get VS Code up and running, install all 12 GB of XCode from the app store, and uninstall Mcafee anti-virus? Hopefully no one has to actually deal with Mcafee anymore, but the rest are pretty feasible. I am not affiliated with them in any way, I just like this course.

Much of this comes from a Front-End Masters Workshop by Brian Holt that can be found here. I'd like to share what I consider the essentials nuggets of knowledge needed to get started developing with Docker. I'll probably butcher a few of these explanations, but that's ok. Though I drowned for a while, during the struggle I learned just enough Docker to get by. Work threw me headfirst into a pool of Docker jargon and buzzwords and forced me to swim. I was one of those people, and my ignorance probably cost me a few month of cumulative development time.įortunately, I was shown the error of my ways. Docker is one of those technologies you never know you need until you use it.
