How to deploy your Vue 3 App on Heroku with Docker and Github Actions

Heroku is a cheap and simple hosting platform to host your apps. Basic hosting costs around 5$/month for many hours of active app. That means that you can host multiple applications for that cost.

Create your app on Heroku

Click "New" and choose "Create new app".

Add "App name", choose a region, and click "Create app".

Create Dockerfile

In your Dockerfile you have to build an app, configure Nginx, and replace $PORT with the actual value.

# Build app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build

# Config Nginx
FROM nginx:stable-alpine as production-stage
ENV PORT=80
COPY ./nginx/default.conf /etc/nginx/conf.d/template
COPY --from=build-stage /web/dist /usr/share/nginx/html

# Replace $PORT with the actual value and run Nginx
CMD /bin/sh -c "envsubst '\$PORT' < /etc/nginx/conf.d/template > /etc/nginx/conf.d/default.conf" && nginx -g 'daemon off;'

Create a Nginx configuration file

In your app main directory create folder nginx and file default.conf inside it.

server {
    listen ${PORT};
    server_name localhost;
    root /usr/share/nginx/html;
    index index.html index.htm;
    location / {
        try_files $uri $uri/ /index.html;
    }
}

Create a Github Action workflow

First, you have to get your Heroku API Key. Go to your "Account Settings" in Heroku.

Then reveal your API Key.

Next, you have to add a repository secret.

Go to your API repository, next "Settings", then "Action" in "Secrets and variables". Click "New repository secret".

The name is up to you, In the Secret field paste your Heroku API Key. Click "Add secret".

Now, you can create a Github Action file.

Go to "Action" and choose "Set up a workflow yourself".

name: Deploy - Web

# Action will be trigger manually (worflow_dispatch) or by pushing on main brach
on:
  push:
    branches: 
      - main

  workflow_dispatch:

jobs:
  build-app:
    runs-on: ubuntu-latest
    steps:
        - uses: actions/checkout@v2
        - name: Deploy to Heroku
          uses: akhileshns/heroku-deploy@v3.12.12 # This is the action
          with:
            # Name of the secret you have added in your repo
            heroku_api_key: ${{secrets.HEROKU_KEY}}
            heroku_app_name: your-heroku-app-name
            heroku_email: your-heroku-account@email.com
            usedocker: true
            appdir: path/to/your/Dockerfile/directory

And... that's it :) After deployment, your app will be hosted on Heroku.
