docker-centos-6.10-vault
CentOS 6 reached its EOL on November 30th, 2020.
When doing so, the main repositories moved its packages to the vault repos.
This caused the official centos:6 Docker image to start failing when trying to update/install packages via yum.
This Docker image solves this issue by removing the original repositories and replacing them with their vaulted version.
The purpose of it is to prevent old pipelines that needed CentOS 6 from failing if they need to install any package.
