Introduction

• The JS7 offers to perform operations on Controllers and Agents by use of the JS7 - REST Web Service API.
  
  • For detailed information see the Technical Documentation of the REST Web Service API.
  • For available CLI operations see JS7 - Unix Shell Command Line Interface.
• The REST Web Service API can be accessed from Shell utilities such as curl.
• In addition, a PowerShell module is available for simplified access to the REST Web Service API. This is described in the JS7 - PowerShell Module article.

The Controller Deployment Script offered for Unix Shell can be applied to perform frequently used deployment operations on Controllers and Agents.

Use of a Controller Cluster or Agent Cluster is subject to the JS7 - License.

Controller Deployment Script

The script is offered for download and can be applied for frequently used deployment operations:

• The script is available for Linux and MacOS® using bash shell.
• The script terminates with exit code 0 to signal successful execution, with exit code 1 for command line argument errors and with exit code 4 for non-recoverable errors. Exit code 3 signals that no matching objects have been found.
• The script is intended as a baseline example for customization by JS7 users and by SOS within the scope of professional services. Examples make use of JS7 Release 2.7.2, bash 4.2, curl 7.29.0 and jq 1.6.0.
  

Prerequisites

The Script requires the curl utility and the jq utility to be available from the operating system. 

jq ships with the MIT license, see https://opensource.org/licenses/MIT.

Commands

• register
  • Allows registering a Controller. The command comes in two flavors:
    • register a Standalone Controller using the --primary-url option.
    • register a Controller Cluster using the --primary-url and --secondary-url options.
  • The URLs specify the protocol, host and optionally port by which the Controller instance can be accessed from JOC Cockpit, for example http://localhost:4444.
  • Controller instances are assigned a Controller ID on installation. When registering the Controller it will automatically use the given Controller ID.
• unregister
  • Allows unregistering a Controller specifying the --controller-id option. Unregistering a Controller deletes the Controller and related Agents from the inventory
• check
  
  • Tests the connection between JOC Cockpit and a Controller instance. The operation is available before a Controller is registered.
  • The --controller-url must be specified that is used from JOC Cockpit to connect to the Controller. 
• store-agent

  • When Agents are stored, then they are added or updated in the inventory and are set to the not deployed status. The command comes in two flavors:

    • store Standalone Agent: requires to specify the --controller-id and --agent-id options that specify the unique identifier of an Agent. The Agent ID cannot be changed later on. The --agent-name option specifies the unique name of an Agent that can be changed later on. The --agent-url option specifies the protocol, host and optionally port by which the Agent can be accessed from the Controller..
    • store Agent Cluster: requires to specify the --controller-id, --agent-id and --agent-name options. An Agent Cluster includes a Primary and Secondary Director Agent. 
      • The Primary Director Agent is specified from the --primary-subagent-id and --primary-url options that are used similarly to above --agent-id and --agent-url options.
      • The Secondary Director Agent is specified from the --secondary-subagent-id and --secondary-url options that are used similarly to above --agent-id and --agent-url options.
  • The deploy-agent command can be used to deploy the Agent configuration.
• delete-agent
  • When Agents are deleted, then they will be deleted from the Controller and from the inventory.
  • Deletion of Agents will be denied by the Controller if we find deployed workflows that hold jobs assigned the Standalone Agent or related Subagent Cluster of an Agent Cluster. The JS7 - Unix Shell CLI for Workflow Deployment offers commands to revoke related workflows.
  • The command is used with the --controller-id and --agent-id options to identify the related Agent.
• deploy-agent
  • When Agents are deployed, then the Agent configuration will be made available to the Controller which connects to the related Agent. As a prerequisite for deployment the Agent must be up & running and must be reachable for the Controller to establish a connection. The same applies to Subagents that have been added to an Agent Cluster using the store-subagent command.
  • The command is used with the --controller-id and --agent-id options to identify the related Agent. For deployment of an Agent Cluster the --cluster switch must be used.
• revoke-agent
  • When Agents are revoked then the Agent configuration is deleted from the Controller, but remains in place with the inventory and will be set to the not deployed status.
  • Revocation of Agents will be denied by the Controller if we find deployed workflows that hold jobs assigned the Standalone Agent or related Subagent Cluster of an Agent Cluster. The JS7 - Unix Shell CLI for Workflow Deployment offers commands to revoke related workflows.
  • The command is used with the --controller-id and --agent-id options to identify the related Agent. For revocation of an Agent Cluster the --cluster switch must be used.
• store-subagent
  • Subagents are used in an Agent Cluster acting as worker nodes to execute jobs. When Subagents are stored, then they are added or updated in the inventory and will be set to the not deployed status. Subagents are not deployed individually. Instead, they are deployed with the Agent Cluster using the deploy-agent command.
  • The command is used with the --controller-id and --agent-id options which identify the Agent Cluster. The --subagent-id and --subagent-url options specify the unique identifier of a Subagent and its URL.
• delete-subagent
  • Subagents are deleted from the Agent Cluster and related Subagent Clusters. The operation deletes Subagents from the Agent Cluster and from the inventory.
  • The command is used with the --controller-id and --subagent-id options to identify the related Subagent.
• store-cluster
  • Subagent Clusters implement clustering from the selection of the Subagents involved and from the scheduling mode being active-passive (fixed-priority) or active-active (round-robin).
  • To store a Subagent Cluster users specify the --controller-id and --agent-id options that identify the Agent Cluster. The --cluster-id option specifies the unique identifier of the cluster to be created. The --subagent-id option specifies one or more Subagents spearated by comma that are used in the cluster. For an active-passive cluster the first Subagent specified will execute the jobs and if it becomes unavailable then the next Subagent will be used.
  • The --priority option specifies an active-passive or active-active cluster. The option accepts one fo the values first (active-passive) or next (active-active). Default: first.
• delete-cluster
  • The Subagent Cluster is deleted from the Agent Cluster and from the inventory. Subagents used in the Subagent Cluster are not deleted.
  • Deletion of a Subagent Cluster will be denied by the Controller if we find deployed workflows that hold jobs assigned the Subagent Cluster. The JS7 - Unix Shell CLI for Workflow Deployment offers commands to revoke related workflows.
  • The command is used with the --controller-id and --cluster-id options to identify the Subagent Cluster.
• deploy-cluster
  • The Subagent Cluster is made available to the Agent Cluster. A deployed Subagent Cluster can be used for assignment to jobs.
  • The command is used with the --controller-id and --cluster-id options to identify the Subagent Cluster.
• revoke-cluster
  • The Subagent Cluster is deleted from the Agent Cluster but remains in place with the inventory and is set to the not deployed status.
  • Revocation of a Subagent Cluster will be denied by the Controller if we find deployed workflows that hold jobs assigned the Subagent Cluster. The JS7 - Unix Shell CLI for Workflow Deployment offers commands to revoke related workflows.
  • The command is used with the --controller-id and --cluster-id options to identify the Subagent Cluster.
• export-agent

  • Agent configurations can be exported to an archive file using the --file option. The archive file will be created in .zip or .tar.gz format using the --format option.

• import-agent
  • For import of Agent configurations users can specify that existing Agent configurations with the same Agent IDs should be overwritten using the --overwrite switch.
• encrypt
  • Allows to encrypt a value using the --in option. If used to encrypt a file then --infile and --outfile options must be specified.
  • The --cert option specifies the path to a file holding the Certificate used for encryption.
  • Encryption is performed by Java libraries that are looked up in the ./lib sub-directory of the  JS7 Unix Shell CLI. For details see JS7 - Encryption and Decryption.
• decrypt
  • Allows to decrypt a value using the --in option. If used to decrypt a file then --infile and --outfile options must be specified.
  • The --key option specifies the path to the Private Key used for decryption. If the Private Key is protected by a password, then the --key-password option or switch must be specified.
  • Decryption is performed by Java libraries that are looked up in the ./lib sub-directory of the JS7 Unix Shell CLI.

Examples

The following examples illustrate use cases for automated deployment of Controller and Agents.

Registering, Checking and Unregistering Controller

Controller instances are assigned a Controller ID on installation. When registering the Controller it will be registered with the given Controller ID.

Users can register a Controller from its URL. Users can check if the connection between JOC Cockpit and Controller can be established. Unregistering a Controller deletes the Controller and related Agents from the inventory

# common options for connection to JS7 REST API
request_options=(--url=http://localhost:4446 --user=root --password=root)  

# register Standalone Controller
./deploy-controller.sh register "${request_options[@]}" \
    --primary-url=http://localhost:4444 --primary-title="Standalone Controller"

# check Standalone Controller Connection
./deploy-controller.sh check "${request_options[@]}" --controller-url=http://localhost:4444

# unregister Standalone Controller
./deploy-controller.sh unregister "${request_options[@]}" --controller-id=controller

In a Controller Cluster both Controller instances are installed using the same Controller ID.

# common options for connection to JS7 REST API
request_options=(--url=http://localhost:4446 --user=root --password=root)

# register Controller Cluster
./deploy-controller.sh register "${request_options[@]}" \
    --primary-url=http://localhost:4544   --primary-title="Primary Controller" \

Storing, Deploying, Revoking and Deleting Agents

Storing and Deploying Agents

When Agents are stored, then they are added or updated in the inventory and are set to the not deployed status.

When Agents are deployed, then the Agent configuration will be made available to the Controller which connects to the related Agent. As a prerequisite for deployment the Agent must be up & running and must be reachable for the Controller to establish a connection. The same applies to Subagents that have been added to an Agent Cluster using the store-subagent command.

# common options for connection to JS7 REST API
request_options=(--url=http://localhost:4446 --user=root --password=root --controller-id=controller)

# store Standalone Agent
./deploy-controller.sh store-agent "${request_options[@]}" \
    --agent-id=StandaloneAgent --agent-name=StandaloneAgent \
    --agent-url="http://localhost:4445" --title="Standalone Agent"

# deploy Standalone Agent
./deploy-controller.sh deploy-agent "${request_options[@]}" --agent-id=StandaloneAgent

An Agent Cluster includes the Primary and Secondary Director Agents. As a prerequisite for deployment the Director Agents must be up & running and must be reachable for the Controller to establish a connection.

# common options for connection to JS7 REST API
request_options=(--url=http://localhost:4446 --user=root --password=root --controller-id=controller)

# store Agent Cluster with Primary/Secondary Director Agent
./deploy-controller.sh store-agent "${request_options[@]}" \
    --agent-id=AgentCluster --agent-name=AgentCluster --title="Agent Cluster" \
    --primary-subagent-id=primary-director     --primary-url=http://localhost:4545   --primary-title="Primary Director" \
    --secondary-subagent-id=secondary-director --secondary-url=http://localhost:4645 --secondary-title="Secondary Director"

# deploy Agent Cluster
./deploy-controller.sh deploy-agent "${request_options[@]}" --agent-id=AgentCluster --cluster

Revoking and Deleting Agents

When Agents are revoked, then they will be deleted from the Controller. The Agent configuration remains in place with the inventory and will be set to the not deployed status.

When Agents are deleted, then they will be deleted from the Controller and from the inventory.

# common options for connection to JS7 REST API
request_options=(--url=http://localhost:4446 --user=root --password=root --controller-id=controller)

# revoke Standalone Agent
./deploy-controller.sh revoke-agent "${request_options[@]}" --agent-id=StandaloneAgent

# delete Standalone Agent
./deploy-controller.sh delete-agent "${request_options[@]}" --agent-id=StandaloneAgent

Revoking an Agent Cluster includes to revoke the Subagents and Subagent Clusters from the Controller using a single operation.

Deleting an Agent Cluster wipes the Agent configuration from both Controller and inventory.

# common options for connection to JS7 REST API
request_options=(--url=http://localhost:4446 --user=root --password=root --controller-id=controller)

# revoke Agent Cluster
./deploy-controller.sh revoke-agent "${request_options[@]}" --agent-id=AgentCluster --cluster

# delete Agent Cluster
./deploy-controller.sh delete-agent "${request_options[@]}" --agent-id=AgentCluster

Storing and Deleting Subagents

When Subagents are stored, then they are added or updated in the inventory and will be set to the not deployed status.

Subagents are not deployed individually. Instead, they are deployed with the Agent Cluster using the deploy-agent command.

# common options for connection to JS7 REST API
request_options=(--url=http://localhost:4446 --user=root --password=root --controller-id=controller)

# store Subagents
./deploy-controller.sh store-subagent "${request_options[@]}" \
    --agent-id=AgentCluster --subagent-id=Subagent_01 \
    --subagent-url=http://localhost:4745 --title="Subagent 01"

./deploy-controller.sh store-subagent "${request_options[@]}" \
    --agent-id=AgentCluster --subagent-id=Subagent_02 \
    --subagent-url=http://localhost:4845 --title="Subagent 02"

# delete Subagents
./deploy-controller.sh delete-subagent "${request_options[@]}" --subagent-id=Subagent_01
./deploy-controller.sh delete-subagent "${request_options[@]}" --subagent-id=Subagent_02

Storing, Deploying, Revoking and Deleting Subagent Clusters

Storing and Deploying Subagent Clusters

When Subagent Clusters are stored, then they are added or updated in the inventory and will be set to the not deployed status.

When Subagent Clusters are deployed, then the cluster configuration will be made available to the Agent Cluster.

# common options for connection to JS7 REST API
request_options=(--url=http://localhost:4446 --user=root --password=root --controller-id=controller)

# store active-passive (fixed-priority) Subagent Cluster
./deploy-controller.sh store-cluster "${request_options[@]}" \
    --agent-id=AgentCluster --cluster-id=active-passive \
    --subagent-id=Subagent_01,Subagent_02 --priority=first --title="Active-Passive Cluster"

# store active-active (round-robin) Subagent Cluster
./deploy-controller.sh store-cluster "${request_options[@]}" \
    --agent-id=AgentCluster --cluster-id=active-active \
    --subagent-id=Subagent_01,Subagent_02 --priority=next --title="Active-Active Cluster"

# deploy Subagent Clusters
./deploy-controller.sh deploy-cluster "${request_options[@]}" --cluster-id=active-passive
./deploy-controller.sh deploy-cluster "${request_options[@]}" --cluster-id=active-active

Revoking and Deleting Subagent Clusters

When Subagent Clusters are revoked, then they are deleted from the Agent Cluster. The cluster configuration remains in place with the inventory and will be set to the not deployed status.

When Subagent Clusters are deleted, then they are deleted from the Agent Cluster and from the inventory.

# common options for connection to JS7 REST API
request_options=(--url=http://localhost:4446 --user=root --password=root --controller-id=controller)

# revoke Subagent Clusters
./deploy-controller.sh revoke-cluster "${request_options[@]}" --cluster-id=active-passive
./deploy-controller.sh revoke-cluster "${request_options[@]}" --cluster-id=active-active

# delete Subagent Clusters
./deploy-controller.sh delete-cluster "${request_options[@]}" --cluster-id=active-passive
./deploy-controller.sh delete-cluster "${request_options[@]}" --cluster-id=active-active

Exporting and Importing Agents

Agent configurations can be exported to an archive file. They can be imported, for example when setting up next JS7 environments.

For import users can specify that existing Agent configurations with the same name should be overwritten.

# common options for connection to JS7 REST API
request_options=(--url=http://localhost:4446 --user=root --password=root --controller-id=controller)

# export Agents from their Agent ID
./deploy-controller.sh export-agent "${request_options[@]}" \
    --file=export_agents.zip --agent-id=StandaloneAgent,AgentCluster

# import Agents
./deploy-controller.sh import-agent "${request_options[@]}" --file=export_agents.zip

Encrypting and Decrypting

• Secrets can be encrypted and decrypted as explaind with JS7 - Encryption and Decryption.
• Encryption/decryption require related Java libraries that are available from the ./lib sub-directory.
• For creation of a Private Key and Certificate see JS7 - How to create X.509 Encryption Keys.
  
  

# create Private Key
openssl ecparam -name secp384r1 -genkey -noout -out encrypt.key

# create Certificate Signing Request
openssl req -new -sha512 -nodes -key encrypt.key -out encrypt.csr -subj "/C=DE/ST=Berlin/L=Berlin/O=SOS/OU=IT/CN=Encrypt"

# create Certificate
openssl x509 -req -sha512 -days 1825 -signkey encrypt.key -in encrypt.csr -out encrypt.crt -extfile <(printf "keyUsage=critical,keyEncipherment,keyAgreement\n")


# encrypt a secret such as a password using the Certificate, the encryption result will be returned and will look like: enc:BEXbHYa...
./deploy-controller.sh encrypt --in="root" --cert=encrypt.crt

# options for connection to the JS7 REST API can specify the encryption result as password and the Private Key for decryption
request_options=(--url=http://localhost:4446 --user=root --password="enc:BEXbHYa..." --key=encrypt.key --controller-id=controller)

# for example, when exporting Agents the Private Key is used to decrypt the password for access to the REST API on-the-fly
./deploy-controller.sh export-agent "${request_options[@]}" --file=export_agents.zip --agent-id=StandaloneAgent,AgentCluster

# decrypt an encrypted secret using the Private Key
./deploy-controller.sh decrypt --in="enc:BEXbHYa..." --key=encrypt.key
