  • Oh, I see that RHEL has officially dropped docker support. You can try installing from binaries, but you are definitely striking out on your own here.

    I don’t mean to rake you over the coals here, but what is the reasoning for sticking with RHEL for this project? If you are attempting to use it in an paid enterprise situation, you are better off sticking with items on the compatibility list. If you run into issues with other supported services, the first piece of advice will be to remove docker. Since your are not getting support for docker, I would advise running it from a supported OS.












  • Yes. A worldwide service provider should be able to achieve at least 4 9s of uptime. That’s 99.99% available, or about <52 minutes of downtime a year. That’s accomplished through best practices with redundancy, planned maintenance, and solid disaster recovery plans.

    The ways to achieve a disaster of this magnitude include:

    • No hot spares
      • A security event has locked all redundant servers and they are now rebuilding servers from backup.
    • Lack of effective redundancy
      • A disaster has occurred at one data center and the load sharing is causing the servers to be unresponsive
        • This is unlikely because there would be intermittent reports of success
    • Poor patching management
      • Patches were sent to all servers without proper testing or rollback strategy
