centos-vault-scl

Custom vault based scl (and rh) yum repositories.

This repository is not associated with the sclorg/centos-release-scl repository nor the Software Collections organisation.

It is a third-party attempt at a 1-liner to add after yum install -y centos-release-scl to then have yum install -y devtoolset-3 (and more) install correctly since the deprecation of older sclo packages.

• Issue for official centos-release-scl
• vfx-platform-discuss Google Groups discussion
• devtoolset-6 was dropped in CentoOS 7.7.1908

Goals

• Provide yum repositories for all http://vault.centos.org/7.*/sclo/$basearch/

  All disabled by default

  • 7.1.1503
  • 7.2.1511
  • 7.3.1611
  • 7.4.1708
  • 7.5.1804
  • 7.6.1810

• Match naming convention as found from CentOS-Vault.repo from centos-release

• Repository/naming will not clash with one from centos-release-scl*

Usage

Install centos-release-scl first, then run activate.sh from master branch.

yum install -y centos-release-scl
curl -sSL https://raw.githubusercontent.com/wwfxuk/centos-vault-scl/master/activate.sh | bash

Then you can install old, archived packages e.g. devtoolset-3

# Should not encounter 404 http errors for missing rpms
yum install -y devtoolset-3

activate.sh

The activate.sh should be run with enough/root permissions to run the following:

1. yum install any dependencies needed (notably for CentOS 7.1):

   • tar, yum-config-manager
   • If any of those are installed, curl is will also be updated to the latest version so it can also pull/download from GitHub (more modern NSS).

2. Extract *.repo files from this repository into /etc/yum.repos.d/

3. Have yum-config-manager enable the relevant C7.x.x-centos-sclo-* yum repositories depending on your current CentOS 7 release.

4. If enabling was successful, the original centos-sclo-* repositories will then be disabled so yum install will fetch packages from our version specific archive rather than from the latest mirrors.

You will still have to manually enable the testing, source and debuginfo repositories if you wish to use packages from those repositories.

They are named C<VERSION>-centos-sclo-<VARIANT>-{testing,source,debuginfo}, e.g. using yum-config-manager

yum-config-manager --enable C7.3.1611-centos-sclo-sclo-debuginfo

Development

1. Modify the CentOS-Vault-SCLo-scl.template.
2. Run bash template-to-repos.sh to generate the *.repo files from the template.
3. Commit those generated *.repo files, replacing existing/old ones.
4. Push as a new branch, submit a pull request
5. Hopefully the CI will start judge whether you are worthy

There may be cases where you might need to change the CI tests e.g. if you are adding a new feature. The main CI workflow files is located in .github/workflows/test-repos.yml.
