Open Stack

It is hard for kolla to support both release of Ubuntu.

Because docker separate the image build from deploy. We have no idea about
the Ubuntu version in Dockerfile
except runing command to test it. We build the image by using Dockerfile.
If we want support multi release of
Ubuntu, the Dockerfile will looks like:


RUN if [[ $(cat /etc/os-release | awk '/VERSION_ID/{print $2}') == '14.04'
]] then; \
        apt-get install openjdk-7-jre \
    elif $(cat /etc/os-release | awk '/VERSION_ID/{print $2}') == '16.04'
]] then; \
        apt-get install openjdk-8-jre
    fi

This is still possible. Think about how to use COPY in the Dockerfile to
support multi Ubuntu release? like

COPY sources.list /etc/apt/sources.list

As far as I can find out is:

COPY sources.list /etc/apt/sources.list
RUN if [[ $(cat /etc/os-release | awk '/VERSION_ID/{print $2}') == '14.04'
]] then; \
        sed -i 's/UBUNTU_RELEASE/trusty/' /etc/apt/sources.list \
    elif $(cat /etc/os-release | awk '/VERSION_ID/{print $2}') == '16.04'
]] then; \
        sed -i 's/UBUNTU_RELEASE/xenial/' /etc/apt/sources.list \
    fi
