Is there any way to build the AzureDevops Buildagent image in offline? - docker

Question

I was following the Microsoft [Doc-][1] to run the ADO build agent in Azure Container registry.
When I tried to build the Docker image by the docker file, getting lot of network related issues.
FROM ubuntu:18.04
# To make it easier for build and release pipelines to run apt-get,
# configure apt to not require confirmation (assume the -y argument by default)
ENV DEBIAN_FRONTEND=noninteractive
RUN echo "APT::Get::Assume-Yes \"true\";" > /etc/apt/apt.conf.d/90assumeyes
RUN apt-get update && apt-get install -y --no-install-recommends \
ca-certificates \
curl \
jq \
git \
iputils-ping \
libcurl4 \
libicu60 \
libunwind8 \
netcat \
libssl1.0 \
&& rm -rf /var/lib/apt/lists/*
RUN curl -LsS https://aka.ms/InstallAzureCLIDeb | bash \
&& rm -rf /var/lib/apt/lists/*
# Can be 'linux-x64', 'linux-arm64', 'linux-arm', 'rhel.6-x64'.
ENV TARGETARCH=linux-x64
WORKDIR /azp
COPY ./start.sh .
RUN chmod +x start.sh
ENTRYPOINT ["./start.sh"]
So I could see there are apt-get update and install commands which are trying for the internet connectivity and getting failed.

Package ca-certificates is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
