SenzingGo

QuickStart

Note: As of Senzing V3, SenzingGo is included in the product installation and doesn't need to be downloaded as outlined below.

Follow the Senzing Quickstart, from the same shell within the project directory:

python3 -m pip install docker
wget -O python/SenzingGo.py https://raw.githubusercontent.com/Senzing/senzinggo/main/SenzingGo.py
chmod +x python/SenzingGo.py

./python/SenzingGo.py

Overview

The SenzingGo utility provides rapid deployment of the following Docker containers on a bare metal Linux installation of the Senzing APIs:

SenzingGo is intended to be easy to use and deploy resources quickly to aid in getting started with the Senzing APIs; without requiring Docker skills. Due to its rapid deployment and ease of use, it is targeted at testing, development and education.

SenzingGo is not intended for production use, it does not provide authentication or secure transport of communications. Such topics are outside the intended use and scope of SenzingGo.

Usage

Although SenzingGo has many arguments, it is executed in its simplest form with no arguments.

./SenzingGo.py

Upon execution the script will:

Perform checks to ensure Docker is installed and the current user has privileges to execute Docker commands
Check for the latest versions of Docker images utilized
Check if there are updates to SenzingGo
Pull the required Docker images (if not already locally available)
Run the Docker images and instantiate running containers for the previously described assets
Print URL information for each of the services provided by the Docker containers

Once complete, access to each of the services is available at the URL and port detailed at the end of the output. For example, in the above output the Senzing demo entity search application is accessible from a browser at http://ant76.anthome:8251.

SenzingGo is designed to be run from within a previously created Senzing project. This facilitates having multiple projects (dev, test, stage or different versions of the Senzing APIs) and distinct containers for the above services serving a single project. A consideration for running multiple projects and instances of the containers started by SenzingGo is specifying different ports than those used by default. See Specifying Ports

Upon startup, and if an internet connection is available, SenzingGo will check for the latest version of the Docker images and attempt to pull them for use. Although an internet connection is usually expected by SenzingGo, and is initially required to pull the Docker images it uses, SenzingGo can work in an 'offline' mode. When offline and an internet connection isn't available, SenzingGo will check the locally available Docker images to determine if the images it needs to start are available. This allows SenzingGo to continue to operate without an internet connection.

There is another use case where it is useful for SeningGo to be able to run offline: air gaped systems. In this use case SenzingGo can be used on an internet connected machine to package the required Docker images together. This package can be moved to an air gapped system where SenzingGo can deploy the Docker images for use without needing to pull them directly from the internet, see Packaging and Deploying the Docker Images

Options

Specifying Ports

Each of the three services will use default ports - 8250, 8251 and 9180 - there are a couple of cases where you may need to specify different port numbers:

The ports 8250, 8251 or 9180 are already in use on the system
There are multiple Senzing API projects on a single system and SenzingGo is to be used with each

In the instance a port is already in use, the following error message (or similar) is displayed and SenzingGo cannot continue.

ERROR: 500 Server Error for http+docker://localhost/v1.41/containers/0e229d2fbf4676a2d8dc5ded8a00dc3c75a7cb44fc189dcf9e43a3aba576a94b/start: Internal Server Error ("driver failed programming external connectivity on endpoint SzGo-API-2_7_0-Release (37b781741cc80ff1bc45c02646272443f91b54171c58890e2814dafb21c444a4): Bind for 0.0.0.0:8250 failed: port is already allocated")

To launch SenzingGo and use alternative port numbers, specify one or more of:

./SenzingGo.py --apiHostPort 8252 --webAppHostPort 8253 --swaggerHostPort 9181

Starting Specific Containers

Running SenzingGo without any parms will start all three of the default containers: Senzing REST API Server, Senzing Entity Search App and the Swagger UI. There may be situations where you don't intend to use all 3 and don't wish to use resources starting them. To choose not to start either the Senzing Entity Search App or the Swagger UI the --noWebApp and --noSwagger options can be used. Note: the REST API Server always starts and is the minimum requirement.

Start the Senzing REST API Server and the Senzing Entity Search App:

./SenzingGo.py --noSwagger

Start only the Senzing REST API Server:

./SenzingGo.py --noWebApp --noSwagger

Cleaning up Containers

When you no longer require the use of any of the services provided by the containers, you can stop and/or clean up the containers:

--contStop
- Stop any containers for the currently active Senzing project
--contRemove
- Stop any containers for the currently active Senzing project, and remove the containers

Information and Logs

Upon completion of execution, SenzingGo displays information relating to the URL and port for each service. If this information is lost sight of from the terminal it can be recalled again by using the --info option. The info option displays the URL and port information along with other pertinent information for the running containers.

The --logs option is used to display each of the logs for currently running containers started by SenzingGo. This can be useful in helping determine problems with starting the containers and will be of use to Senzing support:

./SenzingGo.py --logs

Packaging and Deploying the Docker Images

In situations where the Senzing APIs are being utilized on systems with no internet connection, and there is a requirement to use SenzingGo, SenzingGo can be used on an internet connected machine to package the required Docker images for deployment on the non-internet connected machine. This is typically useful in environments that have air gapped systems. The sequence of events in such a situation would be:

On the internet connected machine ensure the Prerequisites are met
1. 🤔 Installation of the Senzing APIs and creation of a project is not required. SenzingGo can be run standalone when using --saveImages or --loadImages
Run SenzingGo with the --saveImages option
1. No arguments are required to --saveImages

Move the created package to the non-internet connected machine
1. 🤔 If you don't have the Senzing API installation package or SenzingGo.py on the target machine already, transfer them to the target machine now
Run SenzingGo with the --loadImages option, specifying the name of the package, on the non-internet connected machine

At this point the 3 required Docker images should be available on the local machine. Assuming the Senzing APIs have been installed, a Senzing project created and SenzingGo.py is available, SenzingGo will detect there is no internet connection but the required images are available to use as normal.

🤔 Anytime one of the Docker images is updated and the update required on the non-internet connected machine the same process can be repeated to update the images.

When saving the images, a default location will be used (either /tmp or <project_path>/var/), to specify the location to save the package to use the --saveImagesPath option.

./SenzingGo.py --saveImages --saveImagesPath /home/ant

Starting REST Server in Admin Mode

To enable additional functionality in the Senzing REST API Server and Entity Search App the REST Server needs to be started in admin mode. The additional functionality includes making configuration changes via the REST Server and loading data from the Entity Search App. To start the REST server in admin mode:

./SenzingGo.py --apiAdmin

Change Container Name Suffix

By default, SenzingGo will use the name of the project as a suffix when creating the container names to distinguish from containers used by other projects. In the following Docker output note the name of each of the containers created by SenzingGo have the suffix '2_8_3-Release', this is the name of the active Senzing project.

--> docker ps -a --format "{{.ID}}    {{.State}}    {{.Names}}"
10308ec5b7a6    running    SzGo-Swagger-2_8_3-Release
f24ce403b526    running    SzGo-WEB-2_8_3-Release
2012006ef60b    running    SzGo-API-2_8_3-Release

Using the project name helps to identify the containers used by a project. If however, you wanted to use a different suffix the --projectSuffix option can be used:

./SenzingGo.py --projectSuffix My_Sample_Demo

Note the new suffix:

--> docker ps -a --format "{{.ID}}    {{.State}}    {{.Names}}"
9a12e9d225a9    running    SzGo-Swagger-My_Sample_Demo
60de596a90b4    running    SzGo-WEB-My_Sample_Demo
3030d07b2652    running    SzGo-API-My_Sample_Demo

When using --projectSuffix, be aware it is required to be used with other command options. For example, to remove the 3 containers with the --contRemove option, the --projectSuffix option must also be used to specify the suffix.

Db2 CLI Drivers Path

When using Db2 as the Senzing repository you will have already installed the Db2 CLI client and drivers. To mount the drivers into the REST API container for use, SenzingGo must be informed of the location of these drivers on the host system. The path specified for this option should be the location of the Db2 client CLI drivers where the directories such as /cfg and /lib are located, for example /opt/IBM/db2_cli_odbc_driver/odbc_cli/clidriver

./SenzingGo.py --db2CliPath /opt/IBM/db2_cli_odbc_driver/odbc_cli/clidriver
