I'm trying to build a container using this docker file
FROM ubuntu:16.04
RUN apt-get update && apt-get install -y --no-install-recommends \
python3.5 \
python3-pip \
ENTRYPOINT ["/bin/bash"]
For some reason the ENTRYPOINT using ["/bin/bash"] is not being recognize.
When i build the container without the ENTRYPOINT i can run it with no problem using this command with the /bin/bash at the end
docker run -ti -d --name ubunto-teste_2 --rm ubuntu:16.04 /bin/bash
I'm learning linux and docker so i doesn't now much
The error i'm getting is this one

I think is has something to do with the end of line sequence
CodePudding user response：
The backslash after python3-pip looks wrong to me. It means that the line is being continued, which makes the word ENTRYPOINT part of the RUN command.
