I have a container, and i have a json file where is some information to start my api.
The problem is that i need to deploy mutiple container with different json file
So here is my question as we do the COPY in dockerfile is there a way to copy a file into the container on the docker run.
The use of secret is not possible because my client doesn't want to use swarm.
Thanks for reading

You could use the existing image as a base image, and add a new Dockerfile with the single COPY step. Then docker build would add the new file.
Alternatively -- and this is how secrets and configmaps are implemented anyway -- mount the file/folder with the --mount argument with docker run.
CodePudding user response：
Yes.
After you have your container running with docker run
Do a docker ps to get the docker container id or name and
docker cp local file containerid:/remote path
