• Controllers makes use of two configuration files:
  • the general configuration file controller.conf which is available from the following locations:
    • Windows: C:\ProgramData\sos-berlin.com\js7\controller\var\config\agent.conf
    • Unix /var/sos-berlin.com/js7/controller/var/config/agent.conf
  • the security configuration from private.conf is  which is available from the following locations:
    • Windows: C:\ProgramData\sos-berlin.com\js7\controller\var\config\private.conf
    • Unix: /var/sos-berlin.com/js7/controller/var/config/private/private.conf
• The configuration format makes use of Typesafe Config, see JS7 - Configuration Format
• Controller instances have to be restarted to apply changes to the configuration files

...

By default the Controller configuration ships with HTTP communication enabled. It is recommended to create that public/private keys and certificates for secure HTTPS communication are created and to disable HTTP Communicationthat HTTP communication is disabled.

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

...

• A Secondary Controller instance specifies a single node to indicate that this instance starts as a as standby node (Backup).
• This setting is relevant for initial operation only. It is independent from the fact of which Controller instance later on will be the active one and which instance will be the standby instance. 

...

• This setting is used for Controller instances in cluster mode only, it is not used for standalone Controller instances.
• The assignment of Primary and Backup Controller instances is performed by JOC Cockpit during initial operation. It is therefore not required to add settings to Controller configuration files.
• nodes
  • Primary, Backup: For a Primary Controller instance this setting specifies the URLs of the Primary and Backup (Secondary) instance. The URL includes to specify specification of the protocol http/https, the hostname and port.
  • is-backup: For a Secondary Controller instance this setting specifies that during initial operation the given instance will be the standby node.
• watches
  • Watches are Agents in a JS7 environment that are involved in the decision about a fail-over situation. If Controller instances in a cluster are not connected to each other any longer, e.g. due to network errors, then the majority of Agents decides if a fail-over should take place.
  • At least one Agent has to be specified by its URL.

...

• This setting specifies public access to a Controller should if insecure incoming HTTP connections are to be used. If used with a value true then no authentication appliesis applied.
• Default: false

Secure Configuration

It is essential to secure the connections between Controller, Agents and JOC Cockpit. This includes:

• to use using HTTPS connections that are secured by private/public key and certificates,
• to apply applying mutual authentication between Controller and Agent.

...

• This setting specifies public access to a Controller should if insecure incoming HTTP connections are to be used. If used with a the value true then no authentication appliesis not applied.
• Default: false

Security Configuration File: private.conf

...

• When using HTTPS An additional authentication mechanism is applied when using HTTPS Certificates or public keys for incoming connections, see below, then an additional authentication mechanism applies: the client of the incoming connection, e.g. JOC Cockpit, is required to provide a Client Authentication certificate or a password. This includes that two certificates that are in place for a secure HTTPS connection: the given Controller's Server Authentication Certificate and the JOC Cockpit's 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 creating and signing the certificatewhen the certificate is being created and signed.
  • The distinguished name that is specified with the Controller's configuration has to match the Client Authentication Certificate's or Client public key's subject attribute. This attribute specifies the hostname and additional information that is created when the certificate or public key is generated.
• Controller
  • Settings in this section are used for connections from a pairing Controller instance, e.g. for a Secondary Controller instance if the given configuration is used for the Primary Controller instance and vice versa. 
  • distinguished-names: 
    • Specifies the distinguished name as given with the subject of the Client Authentication Certificate for incoming HTTPS connections of a pairing Controller instance.
    • Any number of distinguished names can be specified allowing a number of incoming HTTPS connections from different Controller instances. At a given point in time only one pairing Controller instance can connect to the given Controller.
• History
  • Settings in this section are used for the History Service of JOC Cockpit instances that access the given Controller.
  • distinguished-names:  the same as for the Controller setting.
  • password: a password can be used in addition to use of a certificate or public key. In addition the password is applied in case that will be required if insecure incoming HTTP connections are allowed.
• JOC
  • Settings in this section are used for JOC Cockpit instances that access the given Controller.
  • distinguished-names:  the same as for the Controller setting.
  • password:  a password can be used in addition to use of a certificate or public key. In addition the password is applied in case that will be required if insecure incoming HTTP connections are allowed.
  • permissions: JOC Cockpit requires the UpdateRepo permission to enable users to deploy objects such as workflows.

...

• 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 PKCS#12 format.
• keystore
  • The keystore includes the private key for the Controller's incoming HTTPS connections.
  • Private key types RSA and ECDSA are supported. 
  • file:  the full path to the location of the keystore file is expected.
  • 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.
• truststores
  
  • A truststore contains the certificates or public keys for the Controller's incoming HTTPS connections.
    • Certificates are signed by a Certificate Authority (CA), alternatively a self-signed certificate can be used.
    • It is recommended to use that certificates are used instead of public keys.
    • Certificates of type X.509 are supported.
  • file:  the full path to the location of the truststore file is expected.
  • store-password: A truststore file is protected by a password.
  • A number of truststores can be specified by repeating the file and store-password settings.

...

• For The Controller expects a signature Fof any deployed objects such as workflows the Controller expects a signature. Such signatures are created with a private key and are verified by the Controller based on the available certificates. Agents perform similar signature verification and are configured accordingly.
• 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 deploy deploys objects.
  • for a High Security Level the user creates the signature outside of JOC Cockpit and uploads the signed objects.
• The Controller supports PGP public keys and X.509 certificates. This setting expects a directory respectively 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 signature of deployed objects.
  • X509: specifies the directory from which X.509 certificates are used to verify the signature of deployed objects.

...

• The Controller writes a journal of events that e.g. result , for example, results from order state transitions such as an order starting, failing, completing etc.
• The journal file will grow unlimited indefinately if events are not released. Typically events are consumed by JOC Cockpit and are added to the order and task history. With events being stored persistently to the JOC Cockpit database they Events are released from the Controller's journal once they have been stored persistently to the JOC Cockpit database. The Controller accordingly will free the space consumed by its journal files.
• users-allowed-to-release-events:  specifies the list of accounts that are allowed to send a command to the Controller to release events.
  • Typically the "History" account is specified, this account is used by JOC Cockpit.
  • If more than one account is specified then events are released only after all accounts did send have sent the command to release events to the Controller.
