I am trying to build an image on Bamboo agent where http_proxy is dynamically set by an administrator and keeps changing.
I need to provide apt-get update
and apt-get upgrade -y
in Dockerfile which in turn requires access to this dynamically set corporate http_proxy
Any pointers on how to provide this to docker build
/ Dockerfile?
Basically, I am looking for an option like --build-arg that was introduced in latest docker version.
PS: Upgrading docker version is not an option.

One solution that works on 1.7.1 would be to create a file like env
:
export http_proxy=<your-proxy>
export https_proxy=<your-proxy>
Then in your Dockerfile COPY
it in and then source
it before your apt commands in the RUN
instruction something like:
# Dockerfile
...
COPY env /scripts/
RUN source /scripts/env && \
apt-get update
...
Then you just change the proxy values in the env
file prior to build. Could do this manually or create a hook type script to do it. The obvious massive downside of this is that you're busting your build cache all the time copying the new file in. I don't see any other options because of your (really) old Docker version though.
