Python is considered one of the best languages (in the scientific world) for its simplicity and the vast community, but it tends to be slow and it doesn’t always use all the computational resource we have at hand.
DOCKSTATION CREATE CONTAINER FROM DOCKERFILE CODE
In physics, we want our code to run fast, but as we are not programmers we want also to quickly build a program to test new ideas. When programming, especially for scientific computations, one has to come into terms with both the complexity of the problem and the task of writing a good code. Julia is a high-level dynamic programming language designed to address the needs of high-performance numerical analysis and computational science, without the typical need of separate compilation to be fast, while also being effective for general-purpose programming, web use or as a specification language.

If you can’t wait getting to work with Julia, you can directly skip to Install Docker! About the programs Julia
DOCKSTATION CREATE CONTAINER FROM DOCKERFILE HOW TO
We will show you how to connect a docker container to both VSCode and Atom, though it is suggested to use VSCode as the procedure is simpler and the Julia extension for Atom is no longer under active development.īut first, what are Julia and Docker? The following two paragraphs are meant to give you some context but they are not needed in order to follow through the tutorial. In this guide we will learn how to setup a fully containerized development environment for the Julia language. Connect to the Docker container from Atom.Connect to the Docker container from VSCode.So install core items first and install source code which changes frequently last. The idea is to order your commands by how often they will be updated. Notice we install Gulp and the app dependencies before coping the source. Please note, the instruction order matters. src: Copies the source of our app from the local to the containerĮXPOSE 3000: Our app runs on port 3000 so expose that portĬMD : Set the default command which executes when starting a container with this image. In our case, we simple copied the package.json file.ĬOPY.

RUN npm install -g gulp Run creates a new layer, runs the command and commits the result.ĬOPY package.json /src/package.json: Copies a file or directory from the local dir to the container dir. This applies to the RUN, CMD, ENTRYPOINT, COPY and ADD commands.

WORKDIR /src: Set the working directory for the commands that follow. You could choose another version of Node or start from a base linux image and install Node and your required dependencies individually.

Plus it uses BrowserSync which we’ll demo later.įROM node:4.2.6: We’re going create our image FROM the Official Node 4.2.6 base starting point. It uses Gulp build process so it requires Node. We’ll use the Google Web Starter Kit repo. Finally, we’ll login to Docker Hub and push our image to the repo.įirst, we need a repo to base our image on. Next, we’ll verify the image works correctly by creating a Container. So we’re going to create a Dockerfile, which we’ll use to create an Image. Docker containers are the run component of Docker.” Each container is an isolated and secure application platform. Docker containers can be run, started, stopped, moved, and deleted. Each container is created from a Docker image. A Docker container holds everything that is needed for an application to run. From the documentation… “Docker containers are similar to a directory. ImageLayers is a great tool to visualize the layers shared between images.ĭocker images do not run on their own. Each instructions creates a layer in our image. docker steps through the Dockerfile running each instruction in order. It’s basically the commands you would execute when building the machine manually. Except, instead of building the VM manually and then taking a snapshot, a Docker image is built using a Dockerfile.Ī Dockerfile is simply a set of instructions, think “recipe”, for building the image. The Docker documentation says that a “Docker image is a read-only template.” Conceptually, it is similar to a snapshot of a virtual machine (e.g. Create a docker image from an existing repo and using a Dockerfile and a base image.
