Hello all,
In large servers systems (+50 servers), we encounter issues with package
management.
- we want a central point where it is possible to request package
versions and install new packages,
- we have clusters of machine on which we distribute the load. When
installing new packages, we want softwares to be installed on all the
machines of a cluster and we want all the machines of the cluster to
rollback if installation failed on one,
- We also have redundant servers, #1 being active and #2 ready to take
the load in case of failure of #1. We want the installation to take
place on #2, then we want the service to be switched on #2, then #1 gets
upgraded,
- we want to be able to rollback clusters to the previous know working
configuration after a whole week of test and scrutiny,
- package can be regular software upgrades but also made of
configuration, or database modification.
Do such tools exist? Can we push apt or rpm to do that?
Cheers,
