Problem

This would be a nice feature for creating and deploying of containers on a different (development) machine than the productive ones (which may run via image: option)

Implement Docker Compose Build and Push Workflow

Medium Risk

The current version of Docker Compose does not support a direct build and push command, which limits the ability to build images on a development machine and push them to a registry for deployment. This is due to the separation of build and deployment processes in Docker's architecture, which requires explicit commands to manage images and containers.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Create a Dockerfile

    Ensure you have a Dockerfile in your project directory that defines how to build your application image.

    dockerfile
    FROM node:14
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
CMD ["node", "app.js"]
  2. 2

    Build the Docker Image

    Use the Docker CLI to build your image locally. Replace <image_name> with your desired image name.

    bash
    docker build -t <image_name>:latest .
  3. 3

    Log in to Docker Registry

    Authenticate with your Docker registry to ensure you have permission to push images. Replace <registry_url> with your registry's URL.

    bash
    docker login <registry_url>
  4. 4

    Tag the Docker Image

    Tag your image with the registry URL so it can be pushed correctly. Replace <registry_url> and <image_name> accordingly.

    bash
    docker tag <image_name>:latest <registry_url>/<image_name>:latest
  5. 5

    Push the Docker Image

    Push the tagged image to your Docker registry. Replace <registry_url> and <image_name> accordingly.

    bash
    docker push <registry_url>/<image_name>:latest

Validation

To confirm the fix worked, check the Docker registry for the newly pushed image. You can also pull the image on a different machine using 'docker pull <registry_url>/<image_name>:latest' and run it to ensure it functions as expected.
