Why I cannot log into jaeger-agent docker container?

Question

The only container that I cannot get into and check what's inside is jaeger-agent, downloaded from here.

Why is this so? How can I get inside?

Ideally:

docker exec -it jaeger-agent bash 

would let me in the container

Answer 1

Because it is super minimalist and I do not have the necessary apps on it. However with newer versions things are better.
