automationjutsu/playwright-pytest repository overview

Great point! Since Docker Compose V2 has replaced the old docker-compose command with docker compose, I’ve refined the documentation accordingly. Here’s the final polished version with the latest syntax. 🚀🐳

⁠📌 How to Update and Push the Docker Image

This repository contains a Playwright + Pytest test automation setup with common dependencies.

If you add a new dependency in requirements.txt or modify the code, you need to rebuild and push the updated Docker image to Docker Hub.

⁠🚀 Step-by-Step Guide to Updating and Pushing the Image

1️⃣ Build the new Docker image:

docker compose build

✅ What each flag does:

• docker build → Builds a new Docker image.
• -t automationjutsu/playwright-pytest:latest → Tags (-t) the image with the name automationjutsu/playwright-pytest and the latest tag.
• . → The dot (.) specifies that the Dockerfile is located in the current directory.

2️⃣ Verify that the image was created successfully:

docker images | grep automationjutsu/playwright-pytest

✅ Explanation:

• docker images → Lists all Docker images on your machine.
• | grep automationjutsu/playwright-pytest → Filters the output to show only the relevant image.

3️⃣ Log in to Docker Hub (if not already logged in):

docker login

✅ Explanation:

• This command logs you into your Docker Hub account.
• If you’re not logged in, Docker will ask for your username and password.

4️⃣ Push the updated image to Docker Hub:

docker push automationjutsu/playwright-pytest:latest

✅ Explanation:

• docker push → Uploads the image to Docker Hub.
• automationjutsu/playwright-pytest:latest → Specifies the image name and tag to push.

⁠🐳 Running the Updated Image in a Container

To test the updated Docker image and verify everything works fine:

docker compose run --rm -it automationjutsu/playwright-pytest:latest

✅ Explanation:

• docker run → Starts a new container from the specified image.
• --rm → Automatically removes the container after it stops (useful for temporary runs).
• -it → Runs the container in interactive mode (-i keeps input open, -t allocates a terminal).
• automationjutsu/playwright-pytest:latest → The image name to use.

⁠🎯 If You Use docker compose to Run Tests

If you’re using Docker Compose, update and restart the container with:

docker compose build
docker compose up

✅ Explanation:

• docker compose build → Rebuilds the Docker image based on the docker-compose.yml file.
• docker compose up → Starts the containers defined in docker-compose.yml.
• --force-recreate (optional) → Ensures the latest image is used, even if the container already exists:

  docker compose up --force-recreate
  

  Copy

⁠🔍 Checking Available Docker Images

To list all Docker images stored on your machine:

docker images

✅ Explanation:

• docker images → Displays a list of locally stored Docker images.
• The output shows:
  • REPOSITORY (image name)
  • TAG (version/tag)
  • IMAGE ID
  • SIZE

To remove old images and free up space:

docker rmi <image_id>

✅ Explanation:

• docker rmi <image_id> → Removes an image from the local system.
• Replace <image_id> with the actual IMAGE ID from docker images.

⁠🛑 Stopping and Removing Containers

If a container is running and needs to be stopped:

docker ps  # List running containers
docker stop <container_id>  # Stop a specific container
docker rm <container_id>  # Remove a stopped container

✅ Explanation:

• docker ps → Lists all running containers.
• docker stop <container_id> → Stops a container by its ID.
• docker rm <container_id> → Removes a stopped container from the system.

⁠📌 Summary of Essential Commands

📌 Done! Now you have a well-documented step-by-step guide inside Docker Hub with the latest Docker Compose commands, making it easy to update and push your Playwright Pytest Docker image. 🚀🐳
