Docker-In-Docker daemon proxy settings

[jsm174]

Is it possible to set proxy settings for the docker-in-docker daemon when starting the agent?

For example when I run the agent:

docker run --rm -it -e SERVER_URL="<server>" -e AGENT_NAME="<agent>" -e GIT_SSL_NO_VERIFY=1 -v agent:/data/teamcity_agent/conf --privileged -e DOCKER_IN_DOCKER="start" jetbrains/teamcity-agent

I have to bash in:

docker exec -i -t <container id> /bin/bash

And then add the proxies to /etc/default/docker:

echo "export http_proxy=http://proxy:port" >> /etc/default/docker echo "export https_proxy=http://proxy:port" >> /etc/default/docker

And finally restart the service:

service docker restart

If I don't do this, when building images I get:

[03:25:58][Step 2/3] docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).

There's no possibility to change docker settings as some property, recommended solution is to create new image with dockerfile like

FROM jetbrains/teamcity-agent
ENV DOCKER_IN_DOCKER=start
RUN echo "export http_proxy=http://proxy:port"  >> /etc/default/docker \
    echo "export https_proxy=http://proxy:port" >> /etc/default/docker
