CSE Server Configuration File
The CSE server installation as well runtime is controlled by a yaml configuration file that must be filled out prior to installation. You can generate a skeleton file as follows.
cse sample -o config.yaml
The output of the command varies slightly depending on the target VCD server api version that CSE will be using to talk to VCD (controlled by the flag -v). Only supported message bus type for api version 33.0 and 34.0 is AMQP. For api version 35.0, the default message bus type is MQTT, but AMQP is supported too.
Edit this file to add values from your vCloud Director installation. The following example shows a file with sample values filled out.
# Only one of the amqp or mqtt sections should be present. #amqp: # exchange: cse-ext # host: amqp.vmware.com # password: guest # port: 5672 # prefix: vcd # routing_key: cse # ssl: false # ssl_accept_all: false # username: guest # vhost: / mqtt: verify_ssl: true vcd: api_version: '35.0' host: vcd.vmware.com log: true password: my_secret_password port: 443 username: administrator verify: true vcs: - name: vc1 password: my_secret_password username: firstname.lastname@example.org verify: true - name: vc2 password: my_secret_password username: email@example.com verify: true service: enforce_authorization: false processors : 15 # listeners: 10 log_wire: false telemetry: enable: true broker: catalog: cse default_template_name: my_template default_template_revision: 0 ip_allocation_mode: pool network: mynetwork org: myorg remote_template_cookbook_url: https://raw.githubusercontent.com/vmware/container-service-extension-templates/master/template.yaml storage_profile: '*' vdc: myorgvdc # [Optional] Template rule section # Rules can be defined to override template definitions as defined by remote # template cookbook. # Any rule defined in this section can match exactly one template. # Template name and revision must be provided for the rule to be processed. # Templates will still have the default attributes that were defined during template creation. # These newly defined attributes only affect new cluster deployments from templates. # Template rules can override the following attributes: # * compute_policy # * cpu # * memory # Example 'template_rules' section: #template_rules: #- name: Rule1 # target: # name: photon-v2_k8-1.12_weave-2.3.0 # revision: 1 # action: # compute_policy: "sample policy" # cpu: 4 # mem: 512 #- name: Rule2 # target: # name: my_template # revision: 2 # action: # cpu: 2 # mem: 1024
The config file has 5 mandatory sections ( [
broker) and 1 optional section(
following sub-sections explain the configuration properties for each section
as well as how they are used.
During CSE Server installation, CSE will set up AMQP to ensure
communication between VCD and the running CSE server. The
section controls the AMQP communication parameters. The following
properties will need to be set for all deployments.
|exchange||Exchange name unique to CSE (CSE will create and use this exchange to communicate with VCD)|
|host||IP or hostname of the vCloud Director AMQP server (may be different from the VCD cell hosts)|
Other properties may be left as is or edited to match site conventions.
For more information on AMQP settings, see the VCD API documentation on AMQP.
Starting CSE 3.0.1, CSE will support MQTT message buses for communication with
vCD. The minimum VCD api version required is
35.0. During CSE installation phase,
CSE will setup the MQTT exchange. During CSE upgrades, CSE can switch over from
AMQP to MQTT, however the reverse is not permitted.
|verify_ssl||verify ssl certificates while communicating with the MQTT exchange|
Properties in this section supply credentials necessary for the following operations:
- Guest Operation Program Execution
- Guest Operation Modifications
- Guest Operation Queries
vc under the
vcs section has the following properties:
|name||Name of the vCenter as registered in VCD|
|username||User name of the vCenter service account with at least guest-operation privileges|
|password||Password of the vCenter service account|
Note : All VCs registered in VCD must be listed here, otherwise CSE server installation will fail during pre-check phase.
The service section contains properties that define CSE server behavior.
|listeners||Number of threads that CSE server should use to communicate with AMQP bus and process requests (Removed in CSE 3.0.1)|
|processors||Number of threads that CSE server should use for processing requests (Added in CSE 3.0.1)|
|enforce_authorization||If True, CSE server will use role-based access control, where users without the correct CSE right will not be able to deploy clusters (Added in CSE 1.2.6)|
|log_wire||If True, will log all REST calls initiated by CSE to VCD. (Added in CSE 2.5.0)|
|telemetry||If enabled, will send back anonymized usage data back to VMware (Added in CSE 2.6.0)|
Starting CSE 3.0.1, the
listeners field has been renamed to
broker section contains properties to define resources used by
the CSE server including org and VDC as well as template repository location.
The following table summarizes key parameters.
|catalog||Publicly shared catalog within
|default_template_name||Name of the default template to use if one is not specified during cluster and node operations. CSE server won’t start up if this value is invalid. (Added in CSE 2.5.0)|
|default_template_revision||Revision of the default template to use if one is not is specified during cluster and node operations. CSE server won’t start up if this value is invalid. (Added in CSE 2.5.0)|
|ip_allocation_mode||IP allocation mode to be used during the install process to build the template. Possible values are
|network||Org Network within
|org||VCD organization that contains the shared catalog where the K8s templates will be stored|
|remote_template_cookbook_url||URL of the template repository where all template definitions and associated script files are hosted. (Added in CSE 2.5.0)|
|storage_profile||Name of the storage profile to use when creating the temporary vApp used to build the template|
|vdc||Virtual data-center within
template_rules section is not applicable when CSE 3.0 is configured
with vCD 10.2. Refer Template management for CSE 3.0
(Added in CSE 2.5.0, Deprecated in CSE 3.0.0)
Rules can be created to override some of the default attributes of templates defined by the remote template repository.
This section can contain zero or more such rules, each rule matches exactly one template. Matching is driven by name and revision of the template. If only name is specified without the revision or vice versa, the rule will not be processed.
Each rule comprises of the following attributes
|name||Name of the rule|
|target||Name and revision of the template on which the rule will be applied|
|action||Template properties that will be overridden. Only supported properties are

Enterprise PKS Configuration File for CSE
Sample Enterprise PKS configuration file for CSE can be generated via the following command
cse sample --pks-config -o pks.yaml
Edit this file to add values from your Enterprise PKS installation. The following example shows a file with sample values filled out.
# Enterprise PKS config file to enable Enterprise PKS functionality on CSE # Please fill out the following four sections: # 1. pks_api_servers: # a. Each entry in the list represents a Enterprise PKS api server # that is part of the deployment. # b. The field 'name' in each entry should be unique. The value of # the field has no bearing on the real world Enterprise PKS api # server, it's used to tie in various segments of the config file # together. # c. The field 'vc' represents the name with which the Enterprise PKS # vCenter is registered in VCD. # d. The field 'cpi' needs to be retrieved by executing # 'bosh cpi-config' on Enterprise PKS set up. # 2. pks_accounts: # a. Each entry in the list represents a Enterprise PKS account that # can be used talk to a certain Enterprise PKS api server. # b. The field 'name' in each entry should be unique. The value of # the field has no bearing on the real world Enterprise PKS # accounts, it's used to tie in various segments of the config # file together. # c. The field 'pks_api_server' is a reference to the Enterprise PKS # api server which owns this account. It's value should be equal to # value of the field 'name' of the corresponding Enterprise PKS api # server. # 3. pvdcs: # a. Each entry in the list represents a Provider VDC in VCD that is # backed by a cluster of the Enterprise PKS managed vCenter server. # b. The field 'name' in each entry should be the name of the # Provider VDC as it appears in VCD. # c. The field 'pks_api_server' is a reference to the Enterprise PKS # api server which owns this account. Its value should be equal to # value of the field 'name' of the corresponding Enterprise PKS api # server. # 4. nsxt_servers: # a. Each entry in the list represents a NSX-T server that has been # alongside an Enterprise PKS server to manage its networking. CSE # needs these details to enforce network isolation of clusters. # b. The field 'name' in each entry should be unique. The value of # the field has no bearing on the real world NSX-T server, it's # used to tie in various segments of the config file together. # c. The field 'pks_api_server' is a reference to the Enterprise PKS # api server which owns this account. Its value should be equal to # value of the field 'name' of the corresponding Enterprise PKS api # server. # d.

Encryption and Decryption of the Configuration Files
Starting with CSE 2.6.0, CSE server commands will accept only encrypted configuration files by default. As of now, these are CSE configuration file and Enterprise PKS configuration file. CSE exposes two server CLI commands to help CSE server administrators encrypt and decrypt the configuration files.
cse encrypt config.yaml --output encrypted-config.yaml cse decrypt encrypted-config.yaml -o decrypted-config.yaml
CSE uses industry standard symmetric encryption algorithm Fernet and the encryption is dependent on user provided passwords. It is imperative that CSE server administrators who participate in the encryption process do not lose the password under any circumstances. CSE will not be able to recover the password or permit decryption in such cases. CSE expects all configuration files to be encrypted with the same password.
Whenever an encrypted configuration file is used with CSE server CLI commands,
CSE will prompt the user to provide the password to decrypt them. User can also
propagate the password to CSE via the environment variable
The default behavior can be changed to keep CSE Server accept plain text
configuration files using the flag
--skip-config-decryption with any CSE
command that accepts a configuration file.
