Docker: Error response from daemon: no such id: - docker

Question

currently I try to launch docker image on deamon with docker run -d ID (after to launch this commande: docker build -t toto .)
But when I launch this commande: docker exec -it ID bash, I've got this error:
Error response from daemon: no such id: toto
My Dockerfile look like that:
# Dockerfile
FROM debian:jessie
# Upgrade system
RUN apt-get update && apt-get dist-upgrade -y --no-install-recommends
# Install TOR
RUN apt-get install -y --no-install-recommends tor tor-geoipdb torsocks

RUN echo 'socksParentProxy = "localhost:9050"' >> /etc/polipo/config
RUN echo 'socksProxyType = socks5' >> /etc/polipo/config

RUN echo 'ORPort 9001' >> /etc/tor/torrc
RUN echo 'ExitPolicy reject *:*' >> /etc/tor/torrc
ENV PYTHONPATH $PYTHONPATH:/scrapy
WORKDIR /scrapy
VOLUME ["/scrapy"]
Thanks in advance.

Answer 1

In order to facilitate the usage of docker exec, make sure you run your container with a name:
docker run -d --name aname.cont ...
I don't see an entrypoint or exec directove in the Dockerfile, so do mention what you want to run when using docker run -d
(I like to add '.cont' as a naming convention, to remember that it is a container name, not an image name)
Then a docker exec aname.cont bash should work.
Check that the container is still running with a docker ps -a

Answer 2

When creating the container you should use the image name:
docker run -d --name my_toto toto
You cannot impose an ID when creating it. It's Docker who assigns the ID.
Then connecting
docker exec -it my_toto bash
A more quick way to do that is running directly
docker run -d -it -name my_toto toto bash
The container will still existing after you exit.
