Introduction

This article explains configuration items available for Standalone Agents, Director Agents and Subagents in a JS7 - Agent Cluster. 

• An Agent makes use of two configuration files:
  • the agent.conf general configuration file which is found in the following locations:
    • Windows: C:\ProgramData\sos-berlin.com\js7\agent\var\config\agent.conf
    • Unix /var/sos-berlin.com/js7/agent/var/config/agent.conf
  • the private.conf security configuration file which is found in the following locations:
    
    • Windows: C:\ProgramData\sos-berlin.com\js7\agent\var\config\private.conf
    • Unix: /var/sos-berlin.com/js7/agent/var/config/private/private.conf
  • The configuration format makes use of Typesafe Config, see the JS7 - Configuration Format article.
  • Restart the Agent instance to apply changes to any configuration files.
• For HTTPS configuration refer to the JS7 - Configuration Templates article.

Default Configuration

General Configuration File: agent.conf

HTTP Connections

By default the Agent configuration ships with HTTP connections enabled. It is recommended that public/private keys and certificates for secure HTTPS communication are used and that HTTP connections are disabled.

# Allow http connections without authentication
js7.web.server.auth.public = true

• This setting specifies public access to an Agent if incoming HTTP connections are to be used. If used with a value true then authentication is not applied.
• Default: true

Director Agent Cluster Configuration

If a JS7 - Agent Cluster is used then the following configuration has to be applied for Director Agent instances:

Primary Director Agent Instance Configuration

# Cluster configuration: not required

• A Primary Director Agent instance does not require any configuration items for cluster operation.

Secondary Director Agent Instance Configuration

# Cluster configuration
js7.journal.cluster {
    node {
        is-backup = yes
    }
}

• A Secondary Director Agent instance specifies this setting to indicate that the instance starts as a standby node (Backup). When this setting is not in place, both instances of a Director Agent Cluster will start as standalone instances.
• This setting is relevant for initial operation only. It is independent of which Director Agent instance later on will be the active one and which instance will be the standby one.
• This setting has to be added before starting a Secondary Director Agent instance.

• This setting is used for Director Agent instances in cluster mode only, it is not used for standalone Director Agent instances.
• The registration of Primary and Secondary Director Agent instances is performed by the JOC Cockpit during initial operation.
  • Therefore the only setting required for cluster operation is:
    • js7.journal.cluster.node.is-backup=yes: For a Secondary Director Agent instance this setting specifies that during initial operation the given instance will be the inactive standby node.
  • Additional settings can be applied. However, we recommend that the JOC Cockpit is used instead.
    • nodes
      • Primary, Backup: For a Primary Director Agent instance this setting specifies the URLs of the Primary and Backup (Secondary) instance. The URL includes specification of the http/https protocol, the hostname and port.

Security Configuration File: private.conf

Directory for Trusted Certificates used to verify Signed Workflow Signatures

The Agent requires X.509 certificates and/or PGP public keys to be in place. These are used to verify the signatures of signed workflows. Unsigned workflows are not accepted by an Agent and therefore a minimum of one X.509 certificate file or PGP public key file has to be present in the directories which are specified in the following configuration item:

# Security configuration
js7 {
    configuration {
        # Locations of certificates and public keys used for signature verification
        trusted-signature-keys {
            PGP=${js7.config-directory}"/private/trusted-pgp-keys"
            X509=${js7.config-directory}"/private/trusted-x509-keys"
        }
    }

Explanation:

• The Agent verifies signatures of scheduling objects such as workflows during deployment. This can be performed for PGP and X.509 signatures. 
• The trusted-signature-keys setting specifies the location of PGP public keys and X.509 certificates.
• If no PGP public keys are used or if no X.509 certificates are used then this setting should not be used as it expects the indicated directory to be populated with public keys or certificates respectively.

Script Execution from Signed Workflows

The default Agent configuration allows job scripts which include shell commands to be executed from any location. Without this setting scripts are restricted to being executed from the Agent's config/executables directory only.

# Allow jobs from signed workflows to execute shell commands
js7.job.execution.signed-script-injection-allowed = yes

Secure Configuration

It is essential that the connections between Controller and Agents and between Director Agents and Subagents are secured. This includes:

• using HTTPS connections which are secured by private keys and certificates,
• using authentication between JS7 products:
  • Option 1 (recommended):
    • applying TLS mutual authentication between Controller and Agent,
    • applying TLS mutual authentication between Director Agent instances and Subagents in an Agent Cluster.
  • Option 2:
    • applying password authentication between JS7 products should mutual authentication not be in place.

Client Authentication with Controller

Consider that client authentication is an alternative to Password Authentication with Controller.

Controller Connections

js7 {
    auth {
        # User accounts for https connections
        users {
            # Controller ID for connections by primary/secondary Controller instance
            Controller {
                distinguished-names=[
                    "DNQ=SOS CA, CN=controller-2-0-primary, OU=IT, O=SOS, L=Berlin, ST=Berlin, C=DE",
                    "DNQ=SOS CA, CN=controller-2-0-secondary, OU=IT, O=SOS, L=Berlin, ST=Berlin, C=DE"
                ]
            }
        }
    }
}

Explanation:

• This setting applies to the use of an Agent with a Standalone Controller or with a Controller Cluster.
• Note that the Controller element name is an example that has to be replaced by the Controller ID which is specified with the same value during installation of Controller instances.
• The distinguished-names element identifies the Controller instance's Client Authentication certificate. The certificate acts as a replacement for a password.
  • The Agent configuration specifies the distinguished names of the Controller instances that access the Agent by use of a Client Authentication certificate. For a Standalone Controller there is a single distinguished name, for a Controller Cluster each instance's distinguished name is specified.
  • Except for whitespace between attributes the precise sequence and values as available from the certificate's subject have to match this property value.
  • Note that the common name (CN) element in the distinguished name has to match the fully qualified domain name (FQDN) of a Controller instance's host.

  • The following command can be used to read the distinguished name from a certificate file:
    
    

    Example for OpenSSL command to read a certificate's distinguished name

    # read distinguished name from the a Controller instance's certificate file (.crt)
    openssl x509 -in controller-primary.crt -noout -nameopt RFC2253 -subject
    
    # output is returned with a prefix "subject= " or similar that is not part of the distinguished name
    # subject= DNQ=SOS CA,CN=controller-2-0-primary,OU=IT,O=SOS,L=Berlin,ST=Berlin,C=DE

Password Authentication with Controller

Consider that password authentication is an alternative to Client Authentication with Controller.

Controller Connections

js7 {
    auth {
        # User accounts for https connections
        users {
            # Controller ID for connections by primary/secondary Controller instance
            Controller {
                password="plain:secret"
                # password="sha512:bd2b1aaf7ef4f09be9f52ce2d8d599674d81aa9d6a4421696dc4d93dd0619d682ce56b4d64a9ef097761ced99e0f67265b5f76085e5b0ee7ca4696b2ad6fe2b2"                   }
        }
    }
}

Explanation:

• This setting applies to use of an Agent with a Standalone Controller or with a Controller Cluster.
• Note that the Controller element name is an example that has to be replaced by the Controller ID which is specified with the same value during installation of both cluster Controller instances.
• This setting specifies the password indicated with the Controller instance's js7.auth.agents configuration item. Passwords should be quoted.
  • The password can be specified as plain text preceded by plain:.
  • The password can be specified as a hashed value preceded by sha512:.
    • There are a number of ways to create sha512 hash values from passwords.
    • One possible solution includes using:  echo -n "secret" | openssl dgst -sha512

Director Agent Configuration

The following configuration applies to use of a Director Agent in a JS7 - Agent Cluster. 

A single Director Agent instance and a Director Agent Cluster of two instances can be used. For a single Director Agent instance the explanations provided for the Primary Director Agent apply, settings related to a Secondary Director Agent should be omitted.

The same settings apply as explained for Standalone Agents, see Client Authentication with Controller.

Client Authentication with pairing Director Agent Instance

Consider that client authentication an alternative to Password Authentication with pairing Director Agent Instance.

Director Agent Connections

js7 {
    auth {
        # User accounts for https connections
        users {
            # Subagent ID of pairing Director Agent instance
            subagent-id {
                permissions = [ AgentDirector ]
                distinguished-names=[
                    "DNQ=SOS CA, CN=director-2-0-secondary, OU=IT, O=SOS, L=Berlin, ST=Berlin, C=DE"
                ]
            }
        }
    }
}

Explanation:

• This setting applies to use of the Subagent component within a Director Agent instance in a JS7 - Agent Cluster.
• Note that the subagent-id element name is an example that has to be replaced by the Subagent ID of the pairing Director Agent instance which is specified during configuration of the Agent Cluster. This is not the Agent Cluster ID. For the private.conf file of a Primary Director Agent instance this setting holds the Subagent ID of the Secondary Director Agent instance and vice versa.
• The permissions element should be used as indicated.
• The distinguished-names element identifies the pairing Director Agent instance's Client Authentication certificate. The certificate acts as a replacement for a password.
  
  • Except for whitespace between attributes the precise sequence and values as available from the certificate's subject have to match this property value.
  • Note that the common name (CN) element in the distinguished name has to match the fully qualified domain name (FQDN) of a Director Agent instance's host.

  • The following command can be used to read the distinguished name from a certificate file:
    
    

    Example for OpenSSL command to read a certificate's distinguished name

    # read distinguished name from the pairing Director Agent instance's certificate file (.crt)
    openssl x509 -in director-secondary.crt -noout -nameopt RFC2253 -subject
    
    # output is returned with a prefix "subject= " or similar that is not part of the distinguished name
    # subject= DNQ=SOS CA,CN=director-2-0-secondary,OU=IT,O=SOS,L=Berlin,ST=Berlin,C=DE

Password Authentication with Controller

Consider that password authentication is an alternative to Client Authentication with Controller.

The same settings apply as explained for Standalone Agents, see Password Authentication with Controller.

Password Authentication with pairing Director Agent Instance

Consider that password authentication is an alternative to Client Authentication with pairing Director Agent Instance.

Director Agent Connections

js7 {
    auth {
        # User accounts for https connections
        users {
            # Subagent ID of pairing Director Agent instance
            subagent-id {
                 permissions = [ AgentDirector ]
                 password="plain:secret"
                 # password="sha512:bd2b1aaf7ef4f09be9f52ce2d8d599674d81aa9d6a4421696dc4d93dd0619d682ce56b4d64a9ef097761ced99e0f67265b5f76085e5b0ee7ca4696b2ad6fe2b2"              }
        }
    }
}

Explanation:

• This setting applies to use of a Subagent within a Director Agent instance in an JS7 - Agent Cluster.
• Note that the subagent-id element name is an example that has to be replaced by the Subagent ID of the pairing Director Agent instance which is specified during configuration of the Agent Cluster. This is not the Agent Cluster ID. For the private.conf file of a Primary Director Agent instance this setting holds the Subagent ID of the Secondary Director Agent instance and vice versa.
• The permissions element should be used as indicated.
• The password element specifies the password indicated with the pairing Director Agent instance's js7.auth.subagents configuration item. Passwords should be quoted.
  • The password can be specified as plain text preceded by plain:.
  • The password can be specified as a hashed value preceded by sha512:.
    • There are a number of ways to create sha512 hash values from passwords.
    • One possible solution includes using:  echo -n "secret" | openssl dgst -sha512

Subagent Connections

js7 {
    auth {
        # for each Subagent specify the Subagent ID and password
        subagents {
            director-primary = "plain:secret-director-primary"
            director-secondary = "plain:secret-director-secondary"
            subagent-001 = "plain:secret-subagent-001"
            subagent-002 = "plain:secret-subagent-002"
            subagent-003 = "plain:secret-subagent-003"
         }
    }
}

Explanation:

• This setting applies to connections to a Subagent of a pairing Director Agent instance in a JS7 - Agent Cluster and to connections to any Subagents.
• Note that the director-primary, director-secondary element names are examples that have to be replaced by the Subagent ID of the pairing Director Agent instance which is specified during configuration of the Agent Cluster. This is not the Agent Cluster ID.
• Note that the subagent-001, subagent-002, ... element names are examples for Subagent IDs of connected Subagents.
• The password element specifies the password indicated with the pairing Director Agent instance's and any Subagent's js7.auth.users.<subagent-id>.password configuration item. Passwords should be quoted.
  
  • The password must be specified as plain text preceded by plain:.

                ]
            }
        }
    }
}

Explanation:

• This setting applies to connections from Director Agent instances to the current Subagent in a JS7 - Agent Cluster.
• Note that the director-primary, director-secondary element names are examples that have to be replaced by the Subagent ID of the respective Director Agent instance which is specified during configuration of the Agent Cluster.

Keystore and Truststore

Settings in this section apply to any of Standalone Agents, Director Agent instances and Subagents.

HTTPS Keystore and Truststore Access

js7 {
    web {
        # keystore and truststore location for https connections
        https {
             client-keystore {
                # Default: ${js7.config-directory}"/private/https-client-keystore.p12"
                file=${js7.config-directory}"/private/https-client-keystore.p12"
                key-password="jobscheduler"
                store-password="jobscheduler"
            }

            keystore {
                # Default: ${js7.config-directory}"/private/https-keystore.p12"
                file=${js7.config-directory}"/private/https-keystore.p12"
                key-password="jobscheduler"
                store-password="jobscheduler"
                # alias=
            }

            truststores=[
                {
                    # Default: ${js7.config-directory}"/private/https-truststore.p12"
                    file=${js7.config-directory}"/private/https-truststore.p12"
                    store-password="jobscheduler"
                    # alias=
                }
            ]
        }
    }
}

Explanation:

• HTTPS keystore and truststores are used to hold private keys and certificates.
  • Keystore and truststore settings accept the path to a file in PKCS12 format or in PEM format.
  • The keystore holds the Agent's private key and certificate. This information is used:
    • for Server Authentication with JOC Cockpit and
    • for Client Authentication with Agents.
  • The truststore holds the certificate(s) used to verify:
    • Client Authentication certificates presented by a Controller and
    • Server Authentication certificates challenged by pairing Controllers.
  • A number of truststores can be specified.
• Optionally a separate HTTPS client keystore can be used:
  • The client keystore is used for TLS mutual authentication and holds a private key and certificate created for Client Auth extended key usage. 
  • When using TLS mutual authentication then:
    • a single certificate can be used that is generated for both Server Auth and Client Auth extended key use. In this case do not use the HTTPS client keystore but use the HTTPS keystore to hold the certificate.
    • separate certificates can be used with the certificate for Server Auth key usage being stored with the HTTPS keystore and the certificate for Client Auth key use being stored with the HTTPS client keystore.
  • For details see  JS-1959 - Getting issue details... STATUS
• Keystore and Truststore locations are specified. In addition:
  • a password for the private keys included in the keystore and a password for access to the keystore can be specified,
  • for the truststore a password for access to the truststore can be specified.
• Passwords for keystore and truststore are not intended for security of the configuration, they are used to verify the integrity of certificate stores as the password used for creating and reading the certificate store must be the same.
  • The key-password is used for access to a private key in a keystore.
  • The store-password setting is used for access to a keystore or to a truststore.
  • For PKCS12 keystores both settings have to use the same value. The settings can be omitted if no passwords are used.
• The alias setting can be used for example with a keystore that holds a number of private keys from which the relevant private key is selected by its alias name.

• The Agent detects and makes use of the code page used by the Windows OS

  • for code pages from the above list,
  • for code pages that are prefixed with cp# or CP# with # being the number of the code page.

  
  

• Users can enforce use of a supported code page by adding a setting to the Agent's JS7_AGENT_CONFIG_DIR/agent.conf configuration file such as:
  • js7.job.execution.encoding = "UTF-8"
• This setting specifies the MIME type not the numeric code page identifier, for example UTF-8 instead of 65001.
• Default: the default code page of the Windows operating system is used, for example, 932 for Japan, 850 for Western Europe.

Security Configuration File: private.conf

js7.job.execution: Job Script Execution Permissions

• By default the Agent prevents any commands and scripts from being executed except for scripts located in specific directories. This setting allows any commands and scripts to be executed that the workflow has signed and where the signature has been verified.

js7.job.execution: Job Script Termination

• The Agent can be instructed to terminate running jobs - see the JS7 - FAQ - Does JS7 reliably kill running jobs article.
• The following settings are in place to terminate running jobs by an Agent operated for a Unix OS:
  • The setting kill-with-sigterm-command specifies the OS command executed by the Agent to forward a SIGTERM signal to the running job.
  • The setting kill-with-sigkill-command specifies the OS command executed by the Agent to forward a SIGKILL signal to the running job.
• Both settings are specified as an array of arguments, i.e. "/bin/kill", "-KILL", "$pid" translates to the command: /bin/kill -KILL 99, provided that 99 is the Process ID of the running job.
• This setting can be applied if the Agent is operated on an OS that makes use of a different syntax for the kill command.

js7.configuration: Trusted Signature Keys

• The Agent receives signatures for any deployed objects such as workflows. Such signatures are created with a private key and are verified by the Agent according to the available certificates. 
• When deploying objects with JOC Cockpit:
  • for a low Security Level JOC Cockpit creates the signature from a single private key that is used for any JOC Cockpit user accounts allowed to deploy objects.
  • for a medium Security Level JOC Cockpit creates the signature from the private key of the JOC Cockpit user account that deploys objects.
  • for a high Security Level the user creates the signature outside of JOC Cockpit and uploads the files holding scheduling objects and signatures.
• The Agent supports PGP public keys and X.509 certificates. This setting expects a directory that holds a number of public key files or certificate files.
• trusted-signature-keys
  • PGP: specifies the directory from which PGP public keys are used to verify the signatures of deployed objects.
  • X509: specifies the directory from which X.509 certificates are used to verify the signatures of deployed objects.

js7.auth: HTTPS Authentication and Authorization

• An additional authentication mechanism is applied when using HTTPS certificates or public keys for incoming connections. This includes two certificates that are in place for a secure HTTPS connection: a Server Authentication Certificate and a Client Authentication Certificate. 
  • The fact that a given certificate is to be used for Server Authentication and/or Client Authentication is specified with the key usage when the certificate is being created and signed.
  • The distinguished name that is specified with the Agent's configuration has to match the Client Authentication Certificate's subject attribute. This attribute specifies the hostname and additional information that is created when the certificate or public key is generated.
• js7.auth.users.Controller
  • Settings in this section are used for incoming HTTPS connections from Controller instances.
  • distinguished-names: 
    • Specifies the distinguished name as given with the subject of the Client Authentication Certificate for incoming HTTPS connections from a Controller.
    • One or two distinguished names can be specified allowing incoming HTTPS connections from a Standalone Controller or Controller Cluster.
  • password
    • As an alternative to TLS mutual authentication a password can be specified.
• js7.auth.subagents
  • Settings in this section are used for outgoing HTTPS connections from Director Agent instances to Subagents.

js7.web.https: HTTPS Certificates

• This setting is used to specify the location of a keystore and any truststores used for HTTPS connections.
• Keystore and truststore files are expected in PKCS12 format or in PEM format.
• keystore
  • The keystore includes the private key for the Agent's incoming HTTPS connections.
  • Private key types RSA and ECDSA are supported. 
  • file:  the path to the location of the keystore file is expected.
    • Default: ${js7.config-directory}"/private/https-keystore.p12"
  • key-password: Any keys included with the keystore are protected with a password. The same password has to be used for all private keys in the given keystore.
  • store-password: The keystore file is protected by a password.
  • alias: can be used for example with a keystore that holds a number of private keys from which the relevant private key is selected by its alias name.
• client-keystore
  • Use of this setting is optional. It can be used if separate certificates for Server Authentication and Client Authentication are used.
  • The Client Authentication private key and certificate can be added to this keystore.
  • Included configuration items correspond to the keystore setting.
• truststores
  
  • A truststore contains the certificates or public keys for the Agent's incoming HTTPS connections.
    • Certificates are signed by a Certificate Authority (CA) - alternatively a self-signed certificate can be used.
    • It is recommended that certificates are used instead of public keys.
    • Certificates of type X.509 are supported.
  • file:  the path to the location of the truststore file is expected.
    • Default: ${js7.config-directory}"/private/https-truststore.p12"
  • store-password: A truststore file is protected by a password.
  • alias: can be used for example with a truststore that holds a number of certificates from which the relevant certificate is selected by its alias name.
  • A number of truststores can be specified by repeating the file and store-password settings.

js7.web.server: HTTPS Authentication

• This setting is used to specify the authentication type for HTTPS connections to an Agent.
• https-client-authentication
  
  • The value on (default) specifies that mutual authentication with certificates for Server Authentication and Client Authentication is used.
  • The value off specifies that only HTTP Basic Authentication is used.
• By default JS7 makes use of mutual authentication including both Server and Client Authentication Certificates. This setting can be switched off to use Server Authentication Certificates only.
