Trigger Docker update from git push

I have recently started working with Docker in a simple environment.

I have created a simple blog with the static website generator gatsbyJS.

I have containerized my app with docker:

//Dockerfile

FROM node:11.9.0

WORKDIR /usr/src/app

COPY package*.json ./

RUN npm install  
RUN npm install -g gatsby-cli


COPY . . 

EXPOSE 8000

CMD ["gatsby", "develop", "-H", "0.0.0.0"]

Everything has been pushed and deployed on my server and works as expected.

Each blog post is a markdown file read by gatsbyjs.

My understanding is when all my app will be ready (javascript, css, etc), the only thing I will update is the repository where my posts (markdown files) are as I add a new post.

I think the workflow to adopt is something like:

  1. I wrote a new markdown file
  2. push it to github
  3. trigger a new image and container creation (right?)

enter image description here

Do I have to recreate a new image and container just for a new blog post added?

How can I trigger those actions in my server when the changes are pushed? Which tools should I use?

to trigger a push event you can use hooks.

If you don't want to build a new image every time you add a blog post, you could map the markdowns path to your host. This way you can just put a new markdown file into the mapped volume on your host and your container can use it.
https://docs.docker.com/storage/volumes/

Example:
Add following options to your run order.
docker run ... -v /docker/data/...:/data

Hope this helps.
