You’re welcome!
Yes, since you didn’t change the service name when you were importing the new one, Docker will not let the same names exist, so you have two options.
1. Rename the Container in Docker Compose
If you’re importing your Docker Compose file into Portainer and it conflicts with a container that was previously set up directly through Docker, you can rename the container in your Docker Compose file before importing. Here’s an example of how to do it:
Suppose your original docker-compose.yml has a section like this:
services:
homepage:
image: yourimage
volumes:
- ./config:/app/config
You can rename the service to avoid conflicts:
services:
homepage_new:
image: yourimage
volumes:
- ./config:/app/config
After renaming, import the updated Docker Compose file into Portainer.
2. Remove the Existing Container
If you prefer to keep the same container name as specified in your Docker Compose file, you may opt to remove the existing container that’s causing the conflict. You can do this using the Docker CLI.
Using Docker CLI:
First, stop the container:
docker stop homepage
Then, remove it:
docker rm homepage
After removing the existing container, you can try importing your Docker Compose stack again in Portainer.
If you have volumes just don’t delete those.
