Admin Admin Podcast #64 – Show Notes Enter the Matrix

    • Enabling TLS 1.2 and disabling TLS 1.1, 1.0 and SSL 3.0 and SSL 2.0.
      • Test your Server to what SSL/TLS version you website uses – ssl labs
      • Enable/Disable TLS versions via a GUI  –  IISCrypto
    • Immutable Infrastructures – CoreOS
      • CoreOS is a linux distribution that is completely described by YAML
      • Kubernetes – learnt a bit more about it by actually installing it (kubespray), also, trying to do it in an “air-gapped” environment proved hard work
      • kubespray works by bootstrapping python onto the CoreOS nodes so it can use ansible.
      • Doing Immutable Infrastructure with deb packages?
      • Docker
      • Terraform
        • Plan & Apply stage
        • Providers talk to cloud provider APIs
      • Lab with PXE Booting using Ansible
    • Highly available Network Appliances on OpenStack
      • Allowed_Address_Pairs – 0.0.0.0/1 and 128.0.0.0/1
      • Virtual MAC address between HA members, which means adding an extra Allowed_Address_Pairs pair per Virtual MAC address
      • Ansible with Jinja2 for the Allowed_Address_Pairs variable
    • Ansible 2.5 is out
      • With_SubElements has been depreciated – still works, but documentation refers to loop and lookup plugins
      • loops can have names now

      • Ansible Galaxy roles don’t need to be the files from galaxy.ansible.com – you can use Git repos.

      • Bridges to Telegram and others
