Deploying Your App on KubeSail
How to deploy Node.JS, Python, and Rails apps into Kubernetes
Node.JS
We've created
deploy-node-app
as a migration tool to help you deploy your existing Node.js application into Kubernetes. If you have not yet created an app, you can use create-node-app
to bootstrap a new app with React, Express, Postgres, and Redis with one command.Python
Create a Dockerfile
You can create an image containing your app by placing a file called
Dockerfile
in the root of your project. Update the line with your-daemon-or-script.py
.FROM python:3
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
CMD [ "python", "./your-daemon-or-script.py" ]
Ruby on Rails
Create a Dockerfile
FROM ruby:2.5
RUN apt-get update -qq && apt-get install -y nodejs postgresql-client
RUN mkdir /myapp
WORKDIR /myapp
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN bundle install
COPY . /myapp
EXPOSE 3000
# Start the main process.
CMD ["rails", "server", "-b", "0.0.0.0"]
Building your image
Run
docker build . -t username/your-image-name
docker push username/your-image-name
with
username
being your Dockerhub username.Deploying your app to KubeSail
Once you've built your image and pushed to Docker hub, deploying it to KubeSail is simple! Just update the
image
section of the config below, and then hit apply.Stay in the loop!
