Open the docker container in interactive mode

docker exec -it <container__id> /bin/sh

Then change the prometheus.yml file which should be placed at /etc/prometheus/prometheus.yml

Now, Stop the container and restart the same container. So, now it will read the updated configuration file.

Generic mechanisms to change docker images are

  1. Mount your configuration file at the desired path.

  2. Create a new image by copying the co fig file in the new Dockerfile. Not recommended if you have to use different configs for different environments/apps

  3. Change the file on the running container if the application (peomerheus in this case) supports it. I know that some of the apps like Kibana do this. Good for debugging, not recommended for production environments.

It's hard to be precise with an answer given the lack of details but in general, you place your modified prometheus.yml file within the Docker context and modify your Dockerfile to add the instruction

COPY prometheus.yml /path/to/prometheus.yml
