g-server

Bits and pieces to configure base of your servers in opinionated way with power of Puppet.

When submodule codebase size exceeds common sense it will be moved to its own puppet module.

Features

Interface Sides

You can specify which interfaces are external and which internal.

Other modules/classes can use this information to eg. listen on only some interfaces or create firewall rules.

Configurable as g_server parameters.

Usage:

g_server::get_interfaces($side).each | $iface | { }
g_server::get_side($iface) # => one of G_server::Side

Classes

Accounts

  • Handles root account password and its ssh keys
  • Marks admin users to allow sudo usage
  • Creates user accounts and sets ssh keys

Hiera usage

g_server::accounts::root_password_hash: "$6$9OBVSpVQDgHsldz8$BmiwDh3XGC4qgDL/Qdh5DQPhJ4haNqBvB1KV0BqZwA4w8ZEr3ljcE9YmcVvtkxXqb4uMtl4V3Gk7n0vI2T2NH0"

g_server::accounts::users:
  glorpen:
    ssh_authorized_keys:
      "example.glorpen": "<ssh pub key>"
    admin: true

Cron

Simple cron job wrapper.

  • Setting environment variables
  • Uses ::cron::job
  • Allows using templates with custom variables

Hiera usage

g_server::cron::jobs:
  "example-job":
    minute: "0"
    hour: "10" # "*/5", "1-5", ...
    template_source: "example/job-example.sh.epp"
    #template_content: "puppet://..."
    vars:
      var1: "example"

See glorpen/g_firewall for more.

Network

  • Supports differnating between external and internal facing interfaces
  • Sets internal host names
  • Supports creating macvlan interfaces
  • Sets hostname
  • Allows setting routes, dns, dhcp, gateway, mac per interface
  • Supports IPv6

Hiera usage

g_server::network::interfaces:
  eth0:
    ipv4addr: "192.168.1.12"
    ipv4netmask: "255.255.255.0"
    ipv4gw: "192.168.1.1"
    nameservers:
      - "8.8.8.8"

Repos

  • sets up to date ciphers
  • creates ssh users group
  • sets host keys
  • configures firewall (supports _[Interface Sides]{.title-ref})

Fail2Ban

      root:
        mountpoint: /
        size: 10G
        mount_options: errors=remount-ro,noatime,nodiratime
