2.10.3. 使用 Subscription Manager 运行构建
2.10.3.1. 使用 Subscription Manager 执行 Docker 构建
Docker 策略构建可以使用 Subscription Manager 来安装订阅内容。
先决条件
必须添加授权密钥、Subscription Manager 配置和 Subscription Manager 证书颁发机构，作为构建输入。
流程
使用以下示例 Dockerfile 来通过 Subscription Manager 安装内容：
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
