Remove centos and rhel elements
Several people have popped up in IRC recently with failures in these elements. Without Python 2.7 available in the image they are unsupported (OpenStack hasn't supported it for a long time). Remove these to avoid further confusion. The centos/centos7 DISTRO split that has happened with centos-minimal is unfortunate but I don't think it helps to rename centos7/rhel7 ATM. To summarise; DISTRO=centos7 means image based build, DISTRO=centos && DIB_RELEASE=7 means the minimal build. In the future, I think it is important that the minimal builds and image builds set the same DISTRO. This reflects that "upper" layers shouldn't care about the exact building of the lower layers. I see CentOS 8 going one of two ways 1) the changes are so significant, we start separate centos8 / centos8-minimal elements. They both set DISTRO=centos8 (and DIB_RELEASE to point-release maybe?). This means we have to update all "if DISTRO == centos || DISTRO == centos7" branches to also check for "centos8". Evenually (!) "centos" goes away for versioned DISTRO only 2) we restore centos element with DISTRO=centos and DIB_RELEASE=8, and centos-minimal remains the same. This means we have to audit all "if DISTRO == centos" calls to make sure they're appropriate for version 8 (stick a "&& DIB_RELEASE=7" on them all basically). I'm not sure we can fully decide until we start to see excatly how the distro switching/matching bits look, but (2) is consistent with Ubuntu and probably the preferred solution. Some "rhel" parts have been cleaned up. More could be done in rhel-common, but given our lack of coverage of that I'd prefer to leave it for now. Change-Id: I6ea784116ef59ca22878c8512c963f29c815a00a

# Overrides:
|
||||
|
||||
## General
|
||||
* Downloading the Red Hat Enterprise Linux cloud image requires a valid Red Hat Network login and a subscription to Red Hat Enterprise Linux 6 Server product.
|
||||
* diskimage-builder does not integrate directly with RHN, so a manual download is required. Please visit https://rhn.redhat.com/rhn/software/channel/downloads/Download.do?cid=16952 to download the qcow2 file.
|
||||
* Set DIB_CLOUD_IMAGES to "file:///download_path"
|
||||
* Overriding of DIB_RELEASE is necessary when a new version of the RHEL qcow2 image is available and the default image has not yet been updated in diskimage-builder.
|
||||
|
||||
## Red Hat Subscription Manager (RHSM)
|
||||
|
||||
Certificate-based Red Hat Subscription Management (RHSM) is the default registration type.
|
||||
|
||||
* Set DIB_RHSM_USER and DIB_RHSM_PASSWORD to register the system with RHSM during the image building process. This will apply the associated Red Hat Enterprise Linux Server subscription so the latest package updates can be applied. At the end of the image building process, the system will be unregistered from RHSM.
|
||||
* Set DIB_RHSM_POOL to a subscription pool if you do not want the system to use the `--auto-attach` feature of `subscription-manager`.
|
||||
* Set DIB_RHSM_REPOS to a space-separated list of Red Hat repositories to enable.
|
||||
|
||||
## Red Hat Network (RHN)
|
||||
|
||||
Set `DIB_REG_TYPE=rhn` for Red Hat Network (RHN classic) registration. The image building process will register the system to RHN and apply the associated Red Hat Enterprise Linux Server subscription so the latest package updates can be applied. At the end of the image building process, the system will be unregistered from RHN.
|
||||
|
||||
* For RHN username/password authentication set DIB_RHSM_USER and DIB_RHSM_PASSWORD. To use a Satellite server activation key set DIB_SAT_KEY. If adding RHN channels username and password must be set.
|
||||
* When registering to Satellite set DIB_SAT_URL to the Satellite server URL and DIB_SAT_CERT_RPM_URL to the Satellite certificate.
|
||||
* Set DIB_RHN_CHANNELS to a space-separated list of RHN channels to add. Example: `DIB_RHN_CHANNELS=rhel-x86_64-server-6 rhel-x86_64-server-6-rhscl-1`. RHN username/password is required for this.

deprecations:
|
||||
- |
|
||||
The ``centos`` and ``rhel`` elements have been removed. These
|
||||
were building version 6 which is no longer supported (mostly due
|
||||
to a lack of python 2.7). Version 7 support is available via the
|
||||
``centos7`` and ``rhel7`` elements (which downloads and modifies
|
||||
the upstream cloud images) or via ``centos-minimal`` (which builds
|
||||
the image from a empty chroot; only available for CentOS).
|
||||
``centos-minimal`` is suggested as this is what OpenStack
|
||||
Infrastructure uses for its elements.
|
||||
|
||||
Unfortunately, ``centos-minimal`` sets ``DISTRO=centos`` while
|
||||
``centos7`` sets ``DISTRO=centos7``, despite building the same
|
||||
thing as far as upper levels are concerned. We plan to rectify
|
||||
this in the version 8 time-frame.
