Deploy Vue.js on Google Cloud Run

Repository: WhatDaFox/vuejs-cloud-run-poc

Configure Google Cloud

To be able to build and deploy, you will need a Google Cloud project, with a billing account set up, as well as
the Google Cloud CLI installed.

Then you will need to create a configuration for your project:

$ gcloud config configurations create cloud-run
$ gcloud auth login # and follow the steps
$ gcloud config set project YOUR_PROJECT_ID

Create the project

$ npm i -g @vue/cli
$ vue create cloud-run

Vue CLI creates a Single Page Application type of project, so I needed to install serve to serve the project after the build.

To install serve, run:

$ npm install --save-dev serve

I had to update the package.json file with the "start" script, like so:

"scripts": {
    ...,
    "start": "serve -p $PORT dist/",
}

Now we are ready to create the Dockerfile.

Create the Dockerfile

Now we can build the app and run the start command.

# Use the official lightweight Node.js 12 image.
# https://hub.docker.com/_/node
FROM node:12-alpine

ENV PORT=8080

# Create and change to the app directory.
WORKDIR /usr/src/app

RUN set -ex && \
    adduser node root && \
    chmod g+w /app && \
    apk add --update --no-cache \
      g++ make python \
      openjdk8-jre

# Copy application dependency manifests to the container image.
# A wildcard is used to ensure both package.json AND package-lock.json are copied.
# Copying this separately prevents re-running npm install on every code change.
COPY package*.json ./

# Install production dependencies.
RUN npm ci

# Copy local code to the container image.
COPY . ./

RUN npm run build

# Run the web service on container startup.
CMD [ "npm", "run", "start" ]

Build & Deploy

Now, we can use Cloud Build to build our docker image. Cloud Build will automatically detect our Dockerfile, build,
and push our image in Google Container Registry:

$ gcloud builds submit --tag gcr.io/YOUR_PROJECT/helloworld

Once that's done, we can run the following command to deploy our new revision to Cloud Run:

$ gcloud run deploy --image gcr.io/YOUR_PROJECT/helloworld --platform managed

Benchmark

When testing, I ran a small (to avoid crazy costs) benchmark with Apache Benchmark.

Here is the command I ran:

$ ab -n 1000 -c 80 https://cloud-run-url/

Here are the results:

Conclusion

Really easy to deploy VueJS on Cloud Run and the performances aren't bad, even with a cold start.
