Hello all!
I've recently discovered and join this mailing list; hope I'm in the
right place.
I'm new to the OShift ecosystem, currently trying to develop a
configuration to containerize some apps. I'm using minishift local
cluster on a Ubuntu 16.04 machine (details below).
I want to write a parametrized yaml template to configure the build
process for my layers (those with a dockerStrategy) with using(or,
better said connecting to ) the arguments defined in my Dockerfiles. I
have found that OShift doesn't support ARG instructions prior to the
FROM one when it reads the Dockerfile.
So, even if a docker build would run successfully with something like:
ARG OS_name="centos"
ARG OS_version="6.8"
FROM ${OS_name}:${OS_version}
#....rest of Dockerfile instructions...
if I try to define in my yaml config
strategy:
dockerStrategy:
buildArgs:
- name: OS_name
value: "7"
the build process does not work.
Has anyone else come across this issue and how did you get around it?
What I'm trying to achieve is single configuration structure for
multiple versions, so I wouldn't have to write separate Docker configs
for different app versions. For example building a Java JRE layer on top
of different OSs with one file.
Thank you,
Dan
