How do I tag images in Docker Compose?

You can tag images in Docker Compose by specifying the image name with a tag in your docker-compose.yml file. For example:

services:
  app:
    image: myapp:1.0

Can I use multiple tags for the same image?

No, each image can only have one tag in the docker-compose.yml file. However, you can define multiple services with different tags if needed.

What if I want to build an image with a specific tag?

You can build an image with a specific tag by using the build option along with the image option. For example:

services:
  app:
    build:
      context: .
    image: myapp:1.0

Is it possible to update the image tag after deployment?

Yes, you can update the image tag in your docker-compose.yml file and then run docker-compose up -d to redeploy with the new tag.
