I'm trying to use the bitnami/prometheus container which, according to its documentation, is based on the minideb container image which does not have a shell. I would like to install a Bash shell for debugging purposes. I've noticed that this works on the bitnami/minideb image directly, i.e. the following Dockerfile,
FROM bitnami/minideb:latest
RUN install_packages bash
builds successfully:
> docker build -t prometheus .

However, if I use bitnami/prometheus instead of bitnami/minideb,
FROM bitnami/prometheus:latest
RUN install_packages bash
an attempt to build it leads to an error due to a missing directory /var/lib/apt/lists/partial:
> docker build -t prometheus .

Any idea how to install Bash on bitnami/prometheus?
CodePudding user response：
By default, image bitnami/prometheus already has bash. You can run image bitnami/prometheus with docker run -d bitnami/prometheus:latest and get CONTAINER_ID with docker ps then check with command
docker exec -it CONTAINER_ID /bin/bash
If you want to install other packages use following command in Dockerfile
FROM bitnami/prometheus:latest
RUN apt install package_name
