In this article, I’m going to dockerize Vue application. We know that Docker is a set of platform-as-a-service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Let’s build and run app with Docker.You can take a look at basic docker commands.

Step 1 : Create a Vue Project
You need to install Vue CLI if not installed on your PC.
npm install -g @vue/cli
Then run this command to create a Vue app:
# create project vue create hellovue # go to project folder cd hellovue
Step 2 : Create Dockerfile
A Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image. Create a file named Dockerfile at the root of your project. Now we’re are going to write some commands in the Dockerfile to run our project.
# develop stage FROM node:alpine as develop-stage WORKDIR /app COPY package*.json ./ RUN npm install COPY . . # build stage FROM develop-stage as build-stage RUN npm run build # production stage FROM nginx:alpine as production-stage COPY --from=build-stage /app/dist /usr/share/nginx/html EXPOSE 90 CMD ["nginx", "-g", "daemon off;"]
FROM node:alpine means, Docker will pull nodejs alpine version from Docker Hub. Alpine makes a great docker container, because it is so small and optimized to be run in RAM.
Step 3 : Make .dockerignore File
.dockerignore is to prevent files from being added to the initial build context that is sent to the Docker daemon when we do docker build. Here’s an example:
.git .DS_Store node_modules dist
Step 4 : Build and Run Container
We’ll build the project as a Docker container with this command:
docker build -t hellovue .
Now let’s run the container at port 90:
docker run -p 90:80 hellovue
http://localhost:90 and see the output like this:
We can also run the container with some attributes. Have a look at this page.The tutorial is over. You can download this project from GitHub. Thank you. 🙂
