Python 3 Client app in docker

Python SDK
1

I have a python daemon that runs as a standalone app which access a Couchbase database.
I want to put the daemon app in a docker container.

I am having issues with getting the couchbase dependencies for
libcouchbase-devel, libcouchbase2-bin, gcc, gcc-c++
to install .

Dockerfile-----------------------------------------------------------

FROM python:3.7
COPY requirements.txt requirements.txt

ENV http_proxy http://genproxy.amdocs.com:8080/
ENV https_proxy http://genproxy.amdocs.com:8080/

WORKDIR /atomiq_services

RUN apt-get update
RUN apt-get install -y libcouchbase-devel libcouchbase2-bin gcc gcc-c++

RUN pip install -r requirements.txt

–
Any tips on setting up dockerfile or do you have a premade docker file i could use as a baseline.

Thanks

Hello @Alan_Ennen,

I think the issue is that apt-get cannot find the package gcc-c+.
I believe that the incorrect name of the package on Ubuntu or Debian, and the correct name is g++

Change the line in the Dockerfile, might fix the problem.

RUN apt-get install -y libcouchbase-devel libcouchbase2-bin gcc g++

Updated docker file:

RUN apt-get update
RUN apt-get install -y libcouchbase-devel libcouchbase2-bin gcc g++

Step 7/10 : RUN apt-get install -y libcouchbase-devel libcouchbase2-bin gcc g++

This is another apt-get issue, I suspect the docker image does not have the Couchbase repo installed. The document explains how to add the Couchbase repo and install libcouchbase

Need to add these steps to the Docker file:

wget http://packages.couchbase.com/releases/couchbase-release/couchbase-release-1.0-6-amd64.deb
sudo dpkg -i couchbase-release-1.0-6-amd64.deb
sudo apt-get install -y  libcouchbase-dev libcouchbase2-bin build-essential

Build-essential will install a number of key build tools including gcc and g++

Don’t suppose anyone know of a Dockerfile with Python and Coucbase client already working that i could use as a base.

Hey @Alan_Ennen,

did you solve the problem? I’m getting the same error.
