In docker how do I know what packages are available in the parent image I am using?
I am trying something like:
docker search python
but I get some (network?) error.
I have the image locally. How would I search what packages I can use?

docker search
is the command you use to search for docker images on the docker hub.If I understood well your question, given an image (say
alpine:latest
) you want to know what's inside that image.If that's the case, the only thing you can do IMHO is just run the container and explore it.
You can do that for the alpine:latest image with the following command:
You'll get a prompt inside an instance of the mentioned image and you can dig around to check what's available.
There is no place where you can access informations about the content of an image in a structured way.
