Docker "ImportError: No module named boto" when Boto is installed

In my alpine based docker image, I have installed boto3.output of dockerbuild from docker-compose.

  Running setup.py install for s3cmd: started
    Running setup.py install for s3cmd: finished with status 'done'
Successfully installed awscli-1.14.5 **boto3-1.13.15** botocore-1.8.9 colorama-0.3.7 docutils-0.16 futures-3.3.0 jmespath-0.10.0 pyasn1-0.4.8 python-dateutil-2.8.1  pyyaml-5.3.1 rsa-3.4.2 s3cmd-2.0.1 s3transfer-0.1.13 six-1.15.0

snippet of dockerfile looks like below,

FROM alpine:3.6
RUN apk -v --update add \
        python3 \
        py-pip \
        groff \
        less \
        mailcap \
        curl \
        jq && \
    pip install --upgrade pip && \
    pip install --no-cache-dir awscli==1.14.5 s3cmd==2.0.1 boto3 pyyaml && \
    apk -v --purge del py-pip && \
    rm /var/cache/apk/*

when I try to execute my python package via docker-compose using same Dockerfile: its says 

setup-application_1  |   File "test_cf_create_or_update.py", line 1, in <module>
setup-application_1  |     import boto3
setup-application_1  | ModuleNotFoundError: No module named 'boto3'
localstack_setup-application_1 exited with code 1

I don't know, how to resolve this.

Try:

pip3 install boto3 -t .

It seems that boto is not going to the right target, with "t" flag and ".", you make sure it is seen by all!

Since you are installing python3, you should be using pip3:

   pip3 install --upgrade pip && \
   pip3 install --no-cache-dir awscli==1.14.5 s3cmd==2.0.1 boto3 pyyaml && \

And the in the container you will use python3 to execute your script.

Also worth noting is the fact that since you have fixed the versions of awscli and s3cmd, you will be getting warnings about either too old or too new libraries when building the docker image.
