Build and push a Docker image to a container registry
For many CI and CD workflows, you might want to package and deploy your application as a Docker image after it passes automated tests.
Build a Docker image
Before you can build a Docker image, you need to enable access to the Docker daemon by simply adding the docker: true option to your bitbucket-pipelines.yml file.
Here is an example of how to build a Node.js application as a Docker file. You will need to replace the following placeholders with your own details:
<my.container.registry.io>
<my_app>
<my_tag>
bitbucket-pipelines.yml

script:
- npm install
- npm test
- docker build -t <my.container.registry.io>/<my_app>:<my_tag> .
services:
- dockerPush to a container registry
Once your application has been built into a Docker image, you'll want to push it to a container registry for safe-keeping, ready for deployment.
You'll need to log into your container registry before pushing. Here's an example that builds and pushes a Docker image to a container registry.
First make sure you've set up the variables DOCKER_HUB_USER and DOCKER_HUB_PASSWORD.
Then you will need to replace the following placeholders with your own details:
<my.container.registry.io>
<my_app>
<my_tag>
