Overview
registry.access.redhat.com images may need at times additional components installed with yum. However, they do not come pre-configured with any repository yum may use, so it fails with:
This article describes the procedure to configure the image with the appropriate repositories and entitlements, so yum can be used. Note that entitlements required to access the RPM repository in question are necessary.
Procedure
Prepare a yum repository file. It can be conventionally named redhat.repo. It should list the repositories that contains the dependencies that are needed. A commonly used repository is "rhel-7-server-extras-rpms":
[rhel-7-server-extras-rpms] name = Red Hat Enterprise Linux 7 Server - Extras (RPMs) baseurl = https://cdn.redhat.com/content/dist/rhel/server/7/7Server/$basearch/extras/os ui_repoid_vars = basearch metadata_expire = 86400 sslverify = 1 enabled = 1 gpgcheck = 1 sslclientkey = /etc/pki/entitlement/00000000000000000-key.pem sslclientcert = /etc/pki/entitlement/00000000000000000.pem gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release sslcacert = /etc/rhsm/ca/redhat-uep.pem
Place redhat.repo into a local ./entitlements directory.
Gather entitlements (/etc/pki/entitlement/00000000000000000-key.pem, /etc/pki/entitlement/00000000000000000.pem) and various other cryptographic artifacts (/etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release and /etc/rhsm/ca/redhat-uep.pem) from a system that has them and place them into a local ./entitlements directory.
Use the following Dockerfile fragment:
COPY ./entitlements/redhat.repo /etc/yum.repos.d/redhat.repo COPY ./entitlements/00000000000000000-key.pem /etc/pki/entitlement/00000000000000000-key.pem COPY ./entitlements/00000000000000000.pem /etc/pki/entitlement/00000000000000000.pem COPY ./entitlements/RPM-GPG-KEY-redhat-release /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release COPY ./entitlements/redhat-uep.pem /etc/rhsm/ca/redhat-uep.pem USER root RUN yum -y install crontabs && rm /etc/pki/entitlement/*.pem
