10.3. Running builds with Subscription Manager
10.3.1. Docker builds using Subscription Manager
Docker strategy builds can use the Subscription Manager to install subscription content.
Prerequisites
The entitlement keys, subscription manager configuration, and subscription manager certificate authority must be added as build inputs.
Procedure
Use the following as an example Dockerfile to install content with the Subscription Manager:
FROM registry.redhat.io/rhel7:latest
USER root
# Copy entitlements
COPY ./etc-pki-entitlement /etc/pki/entitlement
# Copy subscription manager configurations
COPY ./rhsm-conf /etc/rhsm
COPY ./rhsm-ca /etc/rhsm/ca
# Delete /etc/rhsm-host to use entitlements from the build container
RUN rm /etc/rhsm-host && \
# Initialize /etc/yum.repos.d/redhat.repo
# See https://access.redhat.com/solutions/1443553
yum repolist --disablerepo=* && \
subscription-manager repos --enable <enabled-repo> && \
yum -y update && \
yum -y install <rpms> && \
# Remove entitlements and Subscription Manager configs
rm -rf /etc/pki/entitlement && \
rm -rf /etc/rhsm
# OpenShift requires images to run as non-root by default
