OCCNE YUM Repository Configuration

To perform an installation without internet access, create a local YUM mirror with the OL7 latest, epel, and addons repositories used by the "OS installation" process. Additionally a local repository is needed to hold the version of the docker-ce RPM used by the "Kubernetes installer" process. Repository files will need to be created to reference these local YUM repositories, and placed on the necessary machines (those which run the OCCNE installation Docker instances).

Pre-requisites

1. Local YUM mirror repository for the OL7 'latest', 'epel', and 'addons' repositories. Directions here: https://www.oracle.com/technetwork/articles/servers-storage-admin/yum-repo-setup-1659167.html

2. Local YUM repository holding the required docker-ce RPM

3. Subscribe to following channels while creating the yum mirror from uln:

   [ol7_x86_64_UEKR5]
   [ol7_x86_64_ksplice]
   [ol7_x86_64_latest]
   [ol7_x86_64_addons]
   [ol7_x86_64_developer]

For reference, view the yum mirroring instructions here: https://www.oracle.com/technetwork/articles/servers-storage-admin/yum-repo-setup-1659167.html

1. Create OL7 repository mirror repo.

   Below is an example of a repository file providing the details on a mirror with the necessary repositories. This repository file would be placed on the machine that will run the OCCNE deployment containers.

   /etc/yum.repos.d/ol7-mirror.repo
   
   [local_ol7_x86_64_UEKR5]
   name=Unbreakable Enterprise Kernel Release 5 for Oracle Linux 7 (x86_64)
   baseurl=http://10.75.155.195/yum/OracleLinux/OL7/UEKR5/$basearch/
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
   enabled=1
   proxy=_none_
     
   [local_ol7_x86_64_latest]
   name=Oracle Linux 7 Latest (x86_64)
   baseurl=http://10.75.155.195/yum/OracleLinux/OL7/latest/$basearch/
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
   enabled=1
   proxy=_none_
     
   [local_ol7_x86_64_addons]
   name=Oracle Linux 7 Addons (x86_64)
   baseurl=http://10.75.155.195/yum/OracleLinux/OL7/addons/$basearch/
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
   enabled=1
   proxy=_none_
     
   [local_ol7_x86_64_ksplice]
   name=Ksplice for Oracle Linux 7 (x86_64)
   baseurl=http://10.75.155.195/yum/OracleLinux/OL7/ksplice/$basearch/
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
   enabled=1
   proxy=_none_
     
   [local_ol7_x86_64_developer]
   name=Packages for creating test and development environments for Oracle Linux 7 (x86_64)
   baseurl=http://10.75.155.195/yum/OracleLinux/OL7/developer/$basearch/
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
   enabled=1
   proxy=_none_
     
   [local_ol7_x86_64_developer_EPEL]
   name=EPEL Packages for creating test and development environments for Oracle Linux 7 (x86_64)
   baseurl=http://10.75.155.195/yum/OracleLinux/OL7/developer/EPEL/$basearch/
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
   enabled=1
   proxy=_none_

2. Create Docker CE repository repo.

   Below is an example of a repository file providing the details on a repository with the necessary docker-ce package.

   /etc/yum.repos.d/docker-ce-stable.repo
   
   [local_docker-ce-stable]
   name=Docker CE Stable (x86_64)
   baseurl=http://10.75.155.195/yum/centos/7/updates/$basearch/
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
   enabled=1

   The docker RPM placed into the repository should be docker-ce version 18.06.1.ce-3.el7 for x86_64 downloaded from: https://download.docker.com/linux/centos/7/x86_64/stable gpg-key for the rpm can be downloaded from: https://download.docker.com/linux/centos/gpg
