Overview

The infrastructure host resource represents any type of host, be it a generic SSH target, a virtual machine (via the child VMHost), or a Container (via the child ContainerHost). By default, the name of the resource will be used for the connect address, however specialised children (such as EC2Host, for example, on AWS) can override this to something that is derived. In particular, please note the VMHost documentation if you want to understand how cloud instance types are chosen. Hosts support both unpriv connections, via connect_user/final_user, and priv connections via admin_connect_user/admin_final_user (this will normally be root on unix!) Note that `connect_user` is the user to connect as, and `final_user` is the user to switch to if a user switch is required. Additionally, instead of supplying authentication details on the host objects directly, you can instantiate a transport_factory resource, which will provide defaults to each host object in the system. You can specify which factory to use by setting the `factory` property on this resource.

Properties (Read/Write)

  • #name ⇒ String
    The name of this resource

    Property Attributes
    
    
    37
    # File 'src/mintpress-infrastructure/lib/mintpress-infrastructure/host.rb', line 37
    
    property :name, type: String
  • #hostname ⇒ String (Default Value: Proc.new { r = self.name.split('.')[0] ; r = nil if r == ''; r })
    The hostname of the box _without_ the DNS domain name - note that individual network interfaces can have different hostnames!

    Property Attributes
    • defaultProc.new { r = self.name.split('.')[0] ; r = nil if r == ''; r }
    
    
    40
    # File 'src/mintpress-infrastructure/lib/mintpress-infrastructure/host.rb', line 40
    
    property :hostname, type: String, default: Proc.new { r = self.name.split('.')[0] ; r = nil if r == ''; r }
  • #dns_domain ⇒ String (Default Value: Proc.new { r = self.name.split('.')[1..-1].join('.') ; r = nil if r == '.' ; r })
    Just the DNS domain name of the box - again, individual network interfaces _can_ override this!

    Property Attributes
    • defaultProc.new { r = self.name.split('.')[1..-1].join('.') ; r = nil if r == '.' ; r }

    property :dns_domain, type: String, default: Proc.new { r = self.name.split('.')[1..-1].join('.') ; r = nil if r == '.' ; r }
  • #max_connections ⇒ Integer
    How many connections, at most, do we allow to this host?

    Property Attributes
    
    
    49
    # File 'src/mintpress-infrastructure/lib/mintpress-infrastructure/host.rb', line 49
    
    property :max_connections, type: Integer
  • #max_connections_per_second ⇒ Float
    How many connections per second, at most, do we allow to this host? This internally defaults to 1.0

    Property Attributes
    
    
    52
    # File 'src/mintpress-infrastructure/lib/mintpress-infrastructure/host.rb', line 52
    
    property :max_connections_per_second, type: Float
  • #affinity_group ⇒ String (Default Value: Proc.new{self.hostname.gsub(/[0-9]/,'').split('.')[0].split('-')[0]})
    Create, by default, an affinity group with no number - note that some infra types don't support named affinity groups, and so this won't work in those cases, and it will always use the node ID in that case

    Property Attributes
    • defaultProc.new{self.hostname.gsub(/[0-9]/,'').split('.')[0].split('-')[0]}
    
    
    56

    property :affinity_group, type: String, default: Proc.new{self.hostname.gsub(/[0-9]/,'').split('.')[0].split('-')[0]}
  • #strict_anti_affinity ⇒ [TrueClass, FalseClass] (Default Value: false)
    Do we strictly enforce anti-affinity, or is it just advisory. Note that if you don't have enough nodes or availability zones to seperate all of your resources, setting this to true _will_ result in failures!

    Property Attributes
    • defaultfalse

  • #host_number ⇒ Integer (Default Value: Proc.new { self.hostname.split('.')[0].split('-')[0].tr("^0-9",'').to_i })
    The numeric ID of this host within an affinity group - this is derived, by default, from the host number. Implementations that have "full" access to the system should convert this back to their own set, so things can be enforced...

    Property Attributes
    • defaultProc.new { self.hostname.split('.')[0].split('-')[0].tr("^0-9",'').to_i }
    
    
    63

  • #connect_address ⇒ String (Default Value: Proc.new { self.fqdn })
    This one should be overridden by children - usually we'll get a useful IP from our provider. Failing that, potentially it should come from network_interfaces if they exist! This might be replaced by an action function at some point, though it'll always be through a prop so that it's overridable

    Should we always use the mintpress internal bootstrap provider, even when anotehr is seperately specified?

Returns a new instance of Host.

Instance Method Details

#admin_transportObject

Retrive the privledged transport for this host

#background_bootstrapObject

#background_createObject

#background_destroyObject

#background_force_bootstrapObject

#background_unbootstrapObject

#bootstrapObject

#createObject

Create our children - other providers will implement creators for the actual machine

#create_admin_transportObject

#create_default_network_interfaceObject

Function to create a default network interface if one does not exist. The reason for this, is so that providers don't have to have multiple code paths for no-net vs net definitions - a definition always exists that matches the default

#create_transportObject

We use transport factory for these, so that we can not constnatly create connections! Since the factory _can_ contain users, lets just let it through for now and let the other side sort it out.... after all, local doens't even need one!

#destroyObject

Destroy our chidren - other providers will implement destroyers for the actual machine

#detect_os_archObject

#detect_os_cpu_countObject

#detect_os_familyObject

One day, this will be our own implementation. Today is not that day.

#detect_os_memory_totalObject

#detect_os_releaseObject

#detect_os_swap_totalObject

#dns_propagated?Boolean

This returns true/false if DNS propagation has happened yet

Returns:

  • (Boolean)

#force_bootstrapObject

#get_local_ip(remote_addr) ⇒ Object

FIXME: this function should consider routes as well... it currently does not, since it's designed for storage really

#guess_primary_ipObject

#guess_tmp_folderObject

Determine location of the temp folder (a) get this from the factory (b) get it from the host (c) default to /tmp

#restartObject

#startObject

#stopObject

#transportObject

Retrieve the unpriv transport for this host

#transport_options(connect_user, final_user, keys, password, key_data, is_admin: false) ⇒ Object

#unbootstrapObject

#uncreatable?(opts = nil) ⇒ Boolean

Returns:

  • (Boolean)

#wait_for_connectable(ip_list, port, timeout = 300, oneshot: false) ⇒ Object

#wait_for_dnsObject

This function will block until all generated DNS has propagated for this host - it's the equivalent of setting `validate_propagated` on your DNS provider, but allows for more fine grained control as to how this occours - the reason you would want to do that, is the actual transport object this class provides _does not care_ if DNS is correct or not for most machine providers, since it gets the IP list from the cloud/vm/container/machine provider directly - so you can do your installs, and only wait for DNS propagation when it comes time to integrate the pieces.

#wait_for_transport(admin: false) ⇒ Object
