    Class ServiceDependencies

    Used to specify other services that must be reachable via the network before a NeonService will be allowed to start. This is exposed via the Dependencies where these values can be configured in code before RunAsync(bool) is called or they can also be configured via environment variables as described in the remarks.

    Inheritance
    object
    ServiceDependencies
    Namespace: Neon.Service
    Assembly: Neon.Service.dll
    Syntax
    public class ServiceDependencies
    Remarks

    This class will be initialized using the following environment variables when present:

    NEON_SERVICE_DEPENDENCIES_URIS=http://foo.com;tcp://10.0.0.55:1234
    NEON_SERVICE_DEPENDENCIES_DISABLE_DNS_CHECK=false
    NEON_SERVICE_DEPENDENCIES_TIMEOUT_SECONDS=30
    NEON_SERVICE_DEPENDENCIES_WAIT_SECONDS=5

    Where you can specify multiple dependency URIs separated by semicolons (;) and the timeout and wait times as seconds.

    note

    Only HTTP, HTTPS, and TCP URIs are supported.

    We also verify that your service is able to perform DNS queries by default by performing a DNS name lookup for DnsCheckHostName (net-check.neoncloud.io). It doesn't matter that this host name is actually registered or that you're cluster has Internet access. We're just looking for any response from the upstream DNS server to determine whether the service has and network connectivity.

    You can disable this by setting DisableDnsChecktrue or the NEON_SERVICE_DEPENDENCIES_DISABLE_DNS_CHECK environment variable to false.

    Constructors

    ServiceDependencies()

    Constructor.

    Declaration
    public ServiceDependencies()

    Fields

    DnsCheckHostName

    The host name used for the DNS availablity check. It doesn't matter that this host name is actually registered or that you're cluster has Internet access. We're just looking for any response from the upstream DNS server.

    Declaration
    public const string DnsCheckHostName = "net-check.neoncloud.io"
    Field Value
    Type Description
    string

    Properties

    DisableDnsCheck

    Use this to disable the DNS availablity check for your service.

    Declaration
    public bool DisableDnsCheck { get; set; }
    Property Value
    Type Description
    bool
    Remarks

    We also verify that your service is able to perform DNS queries by default by performing a DNS name lookup for DnsCheckHostName (net-check.neoncloud.io). It doesn't matter that this host name is actually registered or that you're cluster has Internet access. We're just looking for any response from the upstream DNS server to determine whether the service has and network connectivity.

    You can disable this by setting DisableDnsChecktrue or the NEON_SERVICE_DEPENDENCIES_DISABLE_DNS_CHECK environment variable to false.

    Timeout

    The maximum time to wait for the services specified by Uris to be reachable. You service will be terminated if this is exceeded. This defaults to 120 seconds or the NEON_SERVICE_DEPENDENCIES_TIMEOUT_SECONDS environment variable.

    Declaration
    public TimeSpan Timeout { get; set; }
    Property Value
    Type Description
    TimeSpan

    Uris

    Specifies the URIs for external services that must be reachable via the network before your service will be allowed to start. Only HTTP, HTTPS, and TCP URIs are supported. Any URIs found in the NEON_SERVICE_DEPENDENCIES_URIS environment variables will be added to this list.

    Declaration
    public List<Uri> Uris { get; set; }
    Property Value
    Type Description
    List<Uri>

    Wait

    Additional time to wait after the services specified by Uris are ready before the service will be started. This defaults to 0 seconds or the NEON_SERVICE_DEPENDENCIES_WAIT_SECONDS environment variable.

    Declaration
    public TimeSpan Wait { get; set; }
    Property Value
    Type Description
    TimeSpan
