I have an image called: Image
and a running container called: container
. I want to install pytorch
and anacoda
. what's the easiest way to do this? Do I have to change the dockerfile
and build a new image? Thanks a lot.

Yes, the best thing is to build your image in such a way it has the python modules are in there.
Here is an example. I build an image with the build dependencies:
$ docker build -t oz123/alpine-test-mycoolapp:0.5 - < Image
Sending build context to Docker daemon 2.56 kB
Step 1 : FROM alpine:3.5

Step 2 : ENV MB_VERSION 3.1.4

Step 3 : ENV CFLAGS -O2

Note, I am installing Python's pip inside the image, so later I can download packages from pypi. Packages like numpy might require a C compiler and tool chain, so I am installing these too.
After building the packages which require the build tools chain I remove the tool chain packages:
RUN apk del file pkgconf autoconf m4 automake perl g++ libstdc++
After you have your base image, you can run your application code in an image building on top of it:
$ cat Dockerfile
FROM oz123/alpine-test-mycoolapp
ADD . /code
WORKDIR /code
RUN pip3 install -r requirements.txt -r requirements_dev.txt
RUN pip3 install -e .
RUN make clean
CMD ["pytest", "-vv", "-s"]
I simply run this with docker
.
