Zowe YAML server configuration file reference

Zowe v2 uses a YAML configuration file for server installation, configuration, and runtime. This file is usually referred to as the Zowe configuration YAML file or the zowe.yaml file. YAML is a human-friendly data serialization language for all programming languages. To learn more about YAML specifications, see https://yaml.org/. For a free, offline YAML validator to help validate your syntax, download the Red Hat's VS Code YAML extension.

Content within the YAML file is documented by and validated against schema files which are shipped within Zowe and extended by Zowe extensions. For details on the schema technology and where to find the schema files within our source code, see Using the Configuration Manager.

note

In the following sections, we refer to configuration keys by using the concatenation of key names and dots. For example, if you want to update the configuration key zowe.certificate.keystore.type with value PKCS12, you should set value for this entry in the zowe.yaml:

zowe:
  certificate:
    keystore:
      type: PKCS12

Table of Contents

High-level overview of YAML configuration file​

The YAML configuration file has few high-level sections:

  • zowe
    Defines global configurations specific to Zowe, including default values.
  • java
    Defines Java configurations used by Zowe components.
  • node
    Defines node.js configurations used by Zowe components.
  • zOSMF
    Tells Zowe your z/OSMF configurations.
  • components
    Defines detailed configurations for each Zowe component or extension. Each component or extension may have a key entry under this section. For example, components.gateway is configuration for the API Mediation Layer Gateway service.
  • haInstances
    Defines customized configurations for each High Availability (HA) instance. You should predefine all Zowe HA instances you want to start within your Sysplex.

Extract sharable configuration out of zowe.yaml​

The Zowe YAML configuration file supports splitting into several files or PARMLIB members when "zowe.useConfigmgr" is set to true. This can help simplify grouping configuration changes by type or owner. More details can be found in the configmgr documentation.

Creating portable references​

The Zowe YAML configuration file has template logic for relating one value to another, a system environment variable or symbol, or even to add conditional behavior. This feature is available when "zowe.useConfigmgr" is set to true, and it can help to make your configuration portable between systems that need slightly different behavior while retaining the same configuration file. More details can be found in the configmgr documentation.

Configuration override​

Inside zowe.yaml, you can define default values and they may be overridden in more granular level configurations. This can happen in several ways:

  • The component can override the default certificate configuration. For the specific entry of certification configuration, if it's not overridden, it falls back to default configurations.

Example:

zowe:
  certificate:
    keystore:
      type: PKCS12
      file: /global/zowe/keystore/localhost/localhost.keystore.p12
      password: password
      alias: localhost
    truststore:
      type: PKCS12
      file: /global/zowe/keystore/localhost/localhost.truststore.p12
      password: password
    pem:
      key: /global/zowe/keystore/localhost/localhost.key
      certificate: /global/zowe/keystore/localhost/localhost.cer
      certificateAuthorities: /global/zowe/keystore/local_ca/local_ca.cer
components:
  app-server:
    certificate:
      keystore:
        alias: app-server
      pem:
        key: /global/zowe/keystore/localhost/app-server.key
        certificate: /global/zowe/keystore/localhost/app-server.cer

App Server will use the certificate alias app-server instead of localhost from the same keystore defined in zowe.certificate.keystore.file. And it will use the exact same truststore defined in zowe.certificate.truststore.file.

  • Zowe high availability (HA) instance component configuration haInstances.<ha-instance>.components.<component> can override global level component configurations components.<component>. Any configuration you can find in components.<component> level can be overridden in haInstances.<ha-instance>.components.<component> level. For example, in this configuration:

    components:
      app-server:
        enabled: true
        port: 8544
    haInstances:
      lpar2a:
        components:
          app-server:
            enabled: false
      lpar2b:
        components:
          app-server:
            port: 28544

    App Server on lpar2a HA instance will not be started. On lpar2b HA instance, it will be started but on port 28544.

YAML configurations - certificate​

In Zowe YAML configuration, certificate definition shares the same format and this format can be used in several configuration entries. For example, zowe.certificate, components.<component>.certificate, and haInstances.<ha-instance>.components.<component>.certificate. The certificate definition may include the following entries:

  • keystore.type
    Defines the type of the keystore. If you are using keystore, this value usually should be PKCS12. If you are using keyring, this value should be JCERACFKS.
  • keystore.file
    Defines the path of the keystore file. If you are using keyring, this should look like safkeyring://<keyring-owner>/<keyring-name>. For example, safkeyring://ZWESVUSR/ZoweKeyring.
  • keystore.password
    Defines the password of the keystore.
  • keystore.alias
    Represents the alias name of the certificate stored in keystore. If you are using keyring, this is the certificate label connected to the keyring.
  • truststore.type
    Defines the type of the truststore file. If you are using keystore, this value usually should be PKCS12. If you are using keyring, this value should be JCERACFKS.
  • truststore.file
    Defines the path to the truststore file. If you are using keyring, this should look like safkeyring://<keyring-owner>/<keyring-name>, usually will be the same value of keystore.file.
  • truststore.password
    Defines the password of the truststore.
  • pem.key
    Defines the private key file in PEM format. This can be used by applications that do not support either PKCS12 keystore format or z/OS keyring.
  • pem.certificate
    Defines the public key file in PEM format. This can be used by applications that do not support either PKCS12 keystore format or z/OS keyring.
  • pem.certificateAuthorities
    Defines certificate authorities in PEM format. This can be used by applications that do not support either PKCS12 keystore format or z/OS keyring.

YAML configurations - zowe​

The high-level configuration zowe supports these definitions:

Directories​

  • zowe.runtimeDirectory
    Tells Zowe the runtime directory where it's installed.
  • zowe.logDirectory
    Some Zowe components write logs to file system. This tells Zowe which directory should be used to store log files.
  • zowe.workspaceDirectory Tells Zowe components where they can write temporary runtime files.
  • zowe.extensionDirectory
    Tells Zowe where you put the runtime of all your extensions.

Zowe Job​

  • zowe.job.name
    Defines the Zowe job name for the ZWESLSTC started task.
  • zowe.job.prefix
    Defines the Zowe address space prefix for Zowe components.

Domain and port to access Zowe​

  • zowe.externalDomains
    Defines a list of external domains that will be used by the Zowe instance. This configuration is an array of domain name strings. In Sysplex deployment, this is the DVIPA domain name defined in Sysplex Distributor. For example,

    zowe:
     externalDomains:
     - external.my-company.com
     - additional-dvipa-domain.my-company.com

In Kubernetes deployment, this is the domain name you will use to access your Zowe running in Kubernetes cluster.

  • zowe.externalPort
    Defines the port that will be exposed to external Zowe users. By default, this value is set based on Zowe APIML Gateway port. In Sysplex deployment, this is the DVIPA port defined in Sysplex Distributor. See Configure Sysplex Distributor for more information. In Kubernetes deployment, this is the gateway Service port will be exposed to external.

Extra environment variables​

  • zowe.environments
    Defines extra environment variables to customize the Zowe runtime. This configuration is a list of key / value pairs. Example:

    zowe:
     environments:
       MY_NEW_ENV: value-of-my-env

Please be aware that variables defined here are global to all Zowe components, on all HA instances.

An example use case is to override system-wide environment variables for the Zowe runtime, such as the directory to use for temporary files.

Certificate​

  • zowe.certificate
    Defines the northbound certificate facing Zowe users.
  • zowe.verifyCertificates Defines how Zowe should validate the certificates used by components or external service(s) like z/OSMF. It can be a value of:
    • STRICT: This is the default value. Zowe will validate if the certificate is trusted in our trust store and if the certificate Command Name and Subject Alternative Name (SAN)is validated. This is recommended for the best security.
    • NONSTRICT: Zowe will validate if the certificate is trusted in our trust store. In this mode, Zowe does not validate certificate Common Name and Subject Alternative Name (SAN). This option does not have the best security but allows you to try out Zowe when you don't have permission to fix certificate used by external services like z/OSMF.
    • DISABLED: This will disable certificate validation completely. This is NOT recommended for security purpose.

Launcher and launch scripts​

Launcher is the program behind ZWESLSTC started task.

  • zowe.launcher
    The launcher section defines defaults about how the Zowe launcher should act upon components.
  • zowe.launcher.restartIntervals
    An array of positive integers that defines how many times a component should be tried to be restarted if it fails, and how much time to wait in seconds for that restart to succeed before retrying.
  • zowe.launcher.minUptime
    The minimum amount of time a zowe component should be running in order to be declared as started successfully.
  • zowe.launcher.shareAs
    Whether or not the launcher should start components in the same address space as it. See documentation for _BPX_SHAREAS for details.
  • zowe.launchScript.logLevel You can set it to debug or trace to enable different level of debug messages from Zowe launch scripts. This may help to troubleshoot issues during Zowe start.

Setup​

Zowe YAML configuration uses zowe.setup section to instruct how Zowe should be installed and configured. This section is optional for Zowe runtime but only be used for zwe install and zwe init commands.

YAML configurations - java​

The high-level configuration java supports these definitions:

  • home
    Defines the path to the Java runtime directory.
tip

Ensure the value of node.home in the zowe.yaml is visible to the Zowe STC users, and contains bin/node. Example:

node:
  home: "/usrlppSysplex/nodejs/node-v12.16.1"

The above value is valid only when the path /usrlppSysplex/nodejs/node-v12.16.1/bin/node exists. If you observe output of node:...FSUM7351 not found, check to ensure that the value contains bin/node.

YAML configurations - node​

The high-level configuration node supports these definitions:

  • home
    Defines the path to the Node.js runtime directory.

YAML configurations - zOSMF​

The high-level configuration zOSMF supports these definitions:

  • zOSMF.host
    Defines the hostname of your z/OSMF instance.
  • zOSMF.port
    Defines the port of your z/OSMF instance.
  • zOSMF.applId
    Defines the application ID of your z/OSMF instance.

YAML configurations - components​

All Zowe components and extensions can have a dedicated section under the components high-level configuration.

In this section, <component> represents any Zowe components or extensions. For all components and extensions, these are the common definitions.

  • components.<component>.enabled
    Defines if you want to start this component in this Zowe instance. This allows you to control each component instead of a group.
  • components.<component>.certificate
    You can customize a component to use different certificate from default values. This section follows same format defined in YAML configurations - certificate. If this is not customized, the component will use certificates defined in zowe.certificate.
  • components.<component>.launcher
    Any component can have a launcher section which overrides the overall Zowe Launcher default defined in zowe.launcher.

Configure component gateway​

These configurations can be used under the components.gateway section:

  • port
    Defines the port which the gateway should be started on. This must be a valid port number.
  • debug
    Defines whether to enable debug mode for the Gateway.
  • apiml.service.allowEncodedSlashes
    When this parameter is set to true, the Gateway allows encoded characters to be part of URL requests redirected through the Gateway.
  • apiml.service.corsEnabled
    When this parameter is set to true, CORS are enabled in the API Gateway for Gateway routes gateway/api/v1/**.
  • apiml.service.preferIpAddress
    Set this parameter to true to advertise a service IP address instead of its hostname.
note

This configuration is deprecated. Zowe start script will ignore this value and always set it to false.

  • apiml.gateway.timeoutMillis
    Specifies the timeout for connection to the services in milliseconds.
  • apiml.security.x509.enabled
    Set this parameter to true to enable the client certificate authentication functionality through ZSS.

    Defines the URL where Gateway can query the mapping of client certificates.
  • apiml.security.auth.provider
    Defines the authentication provider used by the API Gateway.
  • apiml.security.authorization.endpoint.url
    Defines the URL to the authorization endpoint. This endpoint tells Gateway if a user has a particular permission on SAF profile. For example, permission to the APIML.SERVICES profile of ZOWE class.
  • apiml.security.ssl.verifySslCertificatesOfServices
    Defines whether APIML should verify certificates of services in strict mode. Setting to true will enable the strict mode where APIML will validate if the certificate is trusted in turststore, and also if the certificate Common Name or Subject Alternate Name (SAN) matches the service hostname.
  • apiml.security.ssl.nonStrictVerifySslCertificatesOfServices
    Defines whether APIML should verify certificates of services in non-strict mode. Setting the value to true will enable the non-strict mode where APIML will validate if the certificate is trusted in turststore, but ignore the certificate Common Name or Subject Alternate Name (SAN) check. Zowe will ignore this configuration when strict mode is enabled with apiml.security.ssl.verifySslCertificatesOfServices.
  • apiml.server.maxConnectionsPerRoute
    Specifies the maximum connections for each service.
  • apiml.server.maxTotalConnections
    Specifies the total connections for all services registered under API Mediation Layer.

  • debug
    Defines whether to enable debug mode for the Discovery Service.
  • apiml.service.preferIpAddress
    Set this parameter to true to advertise a service IP address instead of its hostname.
note

This configuration is deprecated. The Zowe start script will ignore this value and always set it to false.

  • apiml.security.ssl.verifySslCertificatesOfServices
    Defines whether APIML should verify certificates of services in strict mode. Setting to true will enable the strict mode where APIML will validate both if the certificate is trusted in turststore, and also if the certificate Common Name or Subject Alternate Name (SAN) matches the service hostname.
  • apiml.security.ssl.nonStrictVerifySslCertificatesOfServices
    Defines whether APIML should verify certificates of services in non-strict mode. Setting to true will enable the non-strict mode where APIML will validate if the certificate is trusted in turststore, but ignore the certificate Common Name or Subject Alternate Name (SAN) check. Zowe will ignore this configuration if strict mode is enabled with apiml.security.ssl.verifySslCertificatesOfServices.
  • alternativeStaticApiDefinitionsDirectories
    Specifies the alternative directories of static definitions.
  • apiml.server.maxTotalConnections
    Specifies the total connections for all services registered under API Mediation Layer.
  • apiml.discovery.serviceIdPrefixReplacer
    Modifies the service ID of a service instance before it registers to API Mediation Layer. Using this parameter ensures compatibility of services that use a non-conformant organization prefix with v2, based on Zowe v2 conformance.

Configure component api-catalog​

These configurations can be used under the components.api-catalog section:

  • port
    Defines the port which API Catalog should be started on.
  • debug
    Defines if we want to enable debug mode for the API Catalog. This is equivalent to the APIML_DEBUG_MODE_ENABLED variable but with better granular level.
  • environment.preferIpAddress
    Set this parameter to true to advertise a service IP address instead of its hostname.
note

This configuration is deprecated. Zowe start script will ignore this value and always set it to false.

Configure component caching-service​

These configurations can be used under the components.caching-service section:

  • port
    Defines the port which Caching Service should be started on. This may be defined as a valid port number or as an offset from the Gateway component's port. To define an offset enter "+{offset}" or "-{offset}" as a string. The offset must start with + or -.
  • debug
    Defines if we want to enable debug mode for the Caching Service.
  • storage.mode
    Sets the storage type used to persist data in the Caching Service.

    Set this parameter to true to advertise a service IP address instead of its hostname.
note

This configuration is deprecated. Zowe start script will ignore this value and always set it to false.

  • apiml.security.ssl.verifySslCertificatesOfServices
    Specifies whether APIML should verify certificates of services in strict mode. Set to true will enable strict mode that APIML will validate both if the certificate is trusted in turststore, and also if the certificate Common Name or Subject Alternate Name (SAN) match the service hostname.
  • apiml.security.ssl.nonStrictVerifySslCertificatesOfServices
    Defines whether APIML should verify certificates of services in non-strict mode. Setting to true will enable non-strict mode where APIML will validate if the certificate is trusted in turststore, but ignore the certificate Common Name or Subject Alternate Name (SAN) check. Zowe will ignore this configuration if strict mode is enabled with apiml.security.ssl.verifySslCertificatesOfServices.

Configure component app-server​

These configurations can be used under the components.app-server section:

  • port
    Defines the port which App Server should be started on. This may be defined as a valid port number or as an offset from the Gateway component's port. To define an offset enter "+{offset}" or "-{offset}" as a string. The offset must start with + or -.

Configure component zss​

These configurations can be used under the components.zss section:

  • port
    Defines the port which ZSS should be started on. This may be defined as a valid port number or as an offset from the Gateway component's port. To define an offset enter "+{offset}" or "-{offset}" as a string. The offset must start with + or -.

Configure component jobs-api​

These configurations can be used under the components.jobs-api section:

  • port
    Defines the port which Jobs API should be started on. This may be defined as a valid port number or as an offset from the Gateway component's port. To define an offset enter "+{offset}" or "-{offset}" as a string. The offset must start with + or -.

  • debug
    Defines whether to enable debug logging for the Jobs API.

Configure component files-api​

These configurations can be used under the components.files-api section:

  • port
    Defines the port which Files API should be started on. This may be defined as a valid port number or as an offset from the Gateway component's port. To define an offset enter "+{offset}" or "-{offset}" as a string. The offset must start with + or -.

  • debug
    Defines whether to enable debug logging for the Files API.

Configure external extension​

You can define a components.<extension-id> section and use common component configuration entries.

For example, enable my-extension:

components:
  # for extensions, you can add your definition like this
  my-extension:
    enabled: true

YAML configurations - haInstances​

All Zowe high availability instances should have a dedicated section under the haInstances high-level configuration.

In this section, <ha-instance> represents any Zowe high availability instance ID.

For all high availability instances, these are the common definitions.

  • haInstances.<ha-instance>.hostname
    Defines the host name where you want to start this instance. This could be the host name of one LPAR in your Sysplex.
  • haInstances.<ha-instance>.sysname
    Defines the system name of the LPAR where the instance is running. Zowe will use ROUTE command to send JES2 start or stop command to this HA instance.
  • haInstances.<ha-instance>.components.<component>
    Optional settings you can override component configurations for this high availability instance. See Configuration override for more details.

Auto-generated environment variables​

Each line of Zowe YAML configuration will have a matching environment variable during runtime. This is converted based on pre-defined pattern:

  • All configurations under zowe, components, haInstances will be converted to a variable with name:
    • prefixed with ZWE_,
    • any non-alphabetic-numeric characters will be converted to underscore _,
    • and no double underscores like __.
  • Calculated configurations of haInstance, which is portion of haInstances.<current-ha-instance> will be converted same way.
  • Calculated configurations of configs, which is portion of haInstances.<current-ha-instance>.components.<current-component> will be converted same way.
  • All other configuration entries will be converted to a variable with name:
    • all upper cases,
    • any non-alphabetic-numeric characters will be converted to underscore _,
    • and no double underscores like __.

For examples:

  • ZWE_zowe_runtimeDirectory, parent directory of where zwe server command is located.
  • ZWE_zowe_workspaceDirectory is the path of user customized workspace directory.
  • ZWE_zowe_setup_dataset_prefix is the high-level qualifier where Zowe MVS data sets are installed.
  • ZWE_zowe_setup_dataset_parmlib is the data set configured to store customized version of parameter library members.
  • ZWE_zowe_setup_dataset_authPluginLib is the data set configured to store APF authorized ZIS plug-ins load library.
  • ZWE_zowe_setup_security_users_zowe is the name of Zowe runtime user.
  • ZWE_configs_port is your component port number you can use in your start script. It points to the value of haInstances.<current-ha-instance>.components.<your-component>.port, or fall back to components.<my-component>.port, or fall back to configs.port defined in your component manifest.

Troubleshooting your YAML with the Red Hat VS Code extension​

After you download the Red Hat VSCode extension for YAML, YAML validation for your files is turned on by default. Syntax mistakes are highlighted in red. To parse sensitive information, we would highly recommend leaving the data gathering option disabled. To customize your settings, click on the "Extensions" category in VS Code left-hand side workspace, scroll down to YAML Language Support by Red Hat, and click on the gear icon and select "Extension Settings".
