|
"""Class holding all the configuration parameters used by the nsxlib code.
|
|
|
|
:param nsx_api_managers: List of IP addresses of the NSX managers.
|
|
Each IP address should be of the form:
|
|
[<scheme>://]<ip_address>[:<port>]
|
|
If scheme is not provided https is used.
|
|
If port is not provided port 80 is used for http
|
|
and port 443 for https.
|
|
:param username: User name for the NSX manager
|
|
:param password: Password for the NSX manager
|
|
:param client_cert_provider: None, or ClientCertProvider object.
|
|
If specified, nsxlib will use client cert auth
|
|
instead of basic authentication.
|
|
:param insecure: If true, the NSX Manager server certificate is not
|
|
verified. If false the CA bundle specified via "ca_file"
|
|
will be used or if unset the default system root CAs
|
|
will be used.
|
|
:param ca_file: Specify a CA bundle file to use in verifying the NSX
|
|
Manager server certificate. This option is ignored if
|
|
"insecure" is set to True. If "insecure" is set to
|
|
False and ca_file is unset, the system root CAs will
|
|
be used to verify the server certificate.
|
|
|
|
:param concurrent_connections: Maximum concurrent connections to each NSX
|
|
manager.
|
|
:param retries: Maximum number of times to retry a HTTP connection.
|
|
:param http_timeout: The time in seconds before aborting a HTTP connection
|
|
to a NSX manager.
|
|
:param http_read_timeout: The time in seconds before aborting a HTTP read
|
|
response from a NSX manager.
|
|
:param conn_idle_timeout: The amount of time in seconds to wait before
|
|
ensuring connectivity to the NSX manager if no
|
|
manager connection has been used.
|
|
:param http_provider: HTTPProvider object, or None.
|
|
|
|
:param max_attempts: Maximum number of times to retry API requests upon
|
|
stale revision errors.
|
|
|
|
:param plugin_scope: The default scope for the v3 api-version tag
|
|
:param plugin_tag: The value for the v3 api-version tag
|
|
:param plugin_ver: The version of the plugin used as the 'os-api-version'
|
|
tag value in the v3 api-version tag
|
|
:param dns_nameservers: List of nameservers to configure for the DHCP
|
|
binding entries. These will be used if there are
|
|
no nameservers defined on the subnet.
|
|
:param dns_domain: Domain to use for building the hostnames.
|
|
:param dhcp_profile_uuid: Currently unused and deprecated.
|
|
Kept for backward compatibility.
|
|
:param allow_overwrite_header: If True, a default header of
|
|
X-Allow-Overwrite:true will be added to all
|
|
the requests, to allow admin user to update/
|
|
delete all entries.
|
|
:param rate_limit_retry: If True, the client will retry requests failed on
|
|
"Too many requests" error.
|
|
:param cluster_unavailable_retry: If True, skip fatal errors when no
|
|
endpoint in the NSX management cluster is
|
|
available to serve a request, and retry
|
|
the request instead.
|
|
|
|
-- Additional parameters which are relevant only for the Policy manager:
|
|
:param allow_passthrough: If True, use nsx manager api for cases which are
|
|
not supported by the policy manager api.
