I asked chatgpt but it's all manual typing. I <3 Dockge, it would be great if one can make this with a click of the button. :)

✔️ Solution

If you encounter issues with a new Docker image after an update, you can downgrade to the previous image. Here’s a step-by-step guide on how to manage Docker image versions and revert to a previous version if needed:

1. Tag the Current Image: Before updating, tag the current image with a specific version or a backup tag. This ensures you can easily roll back if something goes wrong.

   docker tag current_image:latest current_image:backup

2. Pull the New Image and Update: Pull the new image and apply the update as usual.

   docker pull new_image:latest
   docker-compose up -d

3. Check for Issues: After updating, thoroughly test your application to ensure everything works as expected. If you encounter any problems, proceed to the next step.

4. Rollback to the Previous Image: If the new image causes issues, you can revert to the previously tagged image. Use the docker-compose.yml file to specify the previous version or use the backup tag.

   docker-compose down
   docker tag current_image:backup current_image:latest
   docker-compose up -d

5. Docker Compose Versioning: In your docker-compose.yml file, you can explicitly specify the image version. For example:

   version: '3.8'
   services:
     app:
       image: current_image:backup
       ports:
         - "5000:5000"

6. Remove the Problematic Image: Optionally, you can remove the problematic new image to prevent confusion in the future.

   docker rmi new_image:latest

Using Dockge

If you are using Dockge, the rollback process is similar, but you will do it through its interface:

1. Backup the Current Compose File: Before updating, save a copy of your current docker-compose.yml file.

2. Update and Test: Use the update button in Dockge to update your Docker images and test your application.

3. Rollback via Dockge: If you encounter issues, use the Dockge interface to edit your docker-compose.yml file and specify the previous image version.

4. Deploy: Redeploy the stack with the reverted image version through Dockge.

Example Scenario

1. Before Update:

   docker tag myapp:latest myapp:1.0

2. Update:

   docker pull myapp:latest
   docker-compose up -d

3. Rollback:

   version: '3.8'
   services:
     app:
       image: myapp:1.0

   docker-compose up -d

By tagging your images and managing versions carefully, you can quickly revert to a stable version if an update introduces problems. This ensures minimal downtime and stability for your application.
