Docker Error: Conflict. Container Name Already in Use - How to Fix

This error message indicates that you're trying to create a container named '/chatgpt', but a container with that name already exists. The container ID is '421a8db0f3643b66e5fdcde56ba8c585f41b206f1084298e5bf2e239b3d38f54'.

To reuse the name '/chatgpt', you need to either delete or rename the existing container.

Deleting the Existing Container

Use the following command to delete the container:

docker rm 421a8db0f3643b66e5fdcde56ba8c585f41b206f1084298e5bf2e239b3d38f54

Renaming the Existing Container

Use the following command to rename the container:

docker rename '/chatgpt' '/newname'

Replace '/newname' with the new name you want to give the container.
