    Introduction

    This section explains how to deploy a PAS instance using the official PAS docker image, available on Docker Hub as accusoft/prizmdoc-application-services.

    Note that PAS requires a connection to PrizmDoc Server. For the rest of this section, we assume that you already have a PrizmDoc Server instance or tier deployed. If that's not the case, you might be interested in our Minimal Backend Quick Start which explains how you can quickly deploy a single instance of PAS and PrizmDoc Server together.

    Requirements

    To run PAS as a Docker container, you simply need a Docker host (a machine with Docker installed). See the Docker documentation for more information.

    1. Create a PAS config file

    Before you can run PAS, you'll need a config file. We've included a special init-config command in our Docker image which you can use to create an initial config file.

    Windows (PowerShell)

    First, make sure you've created a config directory on your host file system. This will be the directory where your new config file will be created:

    mkdir config
    
    

    Then, use the Docker image's init-config command to create a new PAS config file:

    docker run --rm -e ACCEPT_EULA=YES --volume $pwd/config:/config accusoft/prizmdoc-application-services init-config
    
    

    This will create a new PAS config file on your Windows host filesystem at .\config\pcc.nix.yml.

    Linux (bash)

    Use the Docker image's init-config command to create a new PAS config file:

    docker run --rm -e ACCEPT_EULA=YES --volume $(pwd)/config:/config accusoft/prizmdoc-application-services init-config
    
    

    This will create a new PAS config file on your host filesystem at ./config/pcc.nix.yml.

    2. Customize your PAS config file

    You will need to customize the contents of the pcc.nix.yml file for your PAS deployment.

    NOTE: On a Linux system, because the config file was created by a Docker container, you will need to either edit the config file as root or change the owner of the file before editing it.

    Typically, you need to:

    • Change the secretKey to your own value (see PAS Configuration for more information).
    • Configure your connection to PrizmDoc Server by updating the pccServer properties:

        pccServer.hostName: your-prizmdoc-server-host
        pccServer.port: 18681
        pccServer.scheme: http
      
      
    • Configure your storage options.

    For more information, see PAS Configuration.

    3. Start PAS

    Assuming you have configured PAS to run on port 3000 and use ./config, ./logs, and ./data directories, you can start PAS like so:

    Windows (PowerShell)

    First, create directories for logs and data:

    mkdir logs
    mkdir data
    
    

    Then, start a pas container:

    docker run --rm --env ACCEPT_EULA=YES --publish 3000:3000 --volume $pwd/config:/config --volume $pwd/logs:/logs --volume $pwd/data:/data --name pas accusoft/prizmdoc-application-services
    
    

    Linux (bash)

    Start a pas container like so:

    docker run --rm --env ACCEPT_EULA=YES --publish 3000:3000 --volume $(pwd)/config:/config --volume $(pwd)/logs:/logs --volume $(pwd)/data:/data --name pas accusoft/prizmdoc-application-services
    
    

    In the examples above:

    • --rm ensures the container is automatically deleted when it stops.
    • --env ACCEPT_EULA=YES indicates you have accepted the PrizmDoc Viewer license agreement.
    • --publish 3000:3000 publishes the container's port to the host. This assumes PAS was configured to use port 3000. If you have configured PAS to use a different port, adjust accordingly.
    • --volume $(pwd)/config:/config maps a host config directory into the container. Your local config directory must contain the pcc.nix.yml config file created earlier.
    • --volume $(pwd)/logs:/logs maps a local logs directory into the container. After the container stops, the logs will remain in this directory.
    • --volume $(pwd)/data:/data maps a local data directory into the container. After the container stops, the data will remain in this directory and can be used again when restarting the container.
    • --name pas sets the name of the running container.
    • accusoft/prizmdoc-application-services is the image that should be run.

    If you want to start the Docker container in the background, add the -d option to docker run to run the container in disconnected mode.

    NOTE: As of PrizmDoc Viewer v13.19, the Docker container starts a single PAS instance. We recommend that you run multiple containers when you need a PAS cluster. However, you can set the environment variable LEGACY_RUN_MULTIPLE_INSTANCES=YES to run multiple PAS instances in the container. The number of instances depends on the CPU cores count on the host machine.

    4. Check PAS health

    After starting PAS, GET http://localhost:3000/health should return HTTP 200, indicating PAS is healthy. If you visit this URL in a browser, you should see "OK" in the body of the page.

    Windows (PowerShell)

    Invoke-WebRequest -Uri http://localhost:3000/health
    
    

    Should output something like:

    StatusCode        : 200
    StatusDescription : OK
    Content           : {79, 75}
    RawContent        : HTTP/1.1 200 OK
                        Connection: keep-alive
                        Content-Length: 2
                        Date: Thu, 21 Nov 2019 17:49:35 GMT
    
                        OK
    Headers           : {[Connection, keep-alive], [Content-Length, 2], [Date, Thu, 21 Nov 2019 17:49:35
                        GMT]}
    RawContentLength  : 2
    
    

    Linux (bash)

    curl -i http://localhost:3000/health
    
    

    Should output something like:

    HTTP/1.1 200 OK
    Date: Wed, 20 Nov 2019 20:00:39 GMT
    Connection: keep-alive
    Content-Length: 2
    
    OK
    
    

    5. Check PAS's connection to PrizmDoc Server

    After starting PAS, GET http://localhost:3000/servicesConnection should return HTTP 200, indicating PAS is configured correctly to make requests to PrizmDoc Server. If you visit this URL in a browser, you should see "OK" in the body of the page.

    Windows (PowerShell)

    Invoke-WebRequest -Uri http://localhost:3000/servicesConnection
    
    

    Should output something like:

    StatusCode        : 200
    StatusDescription : OK
    Content           : {79, 75}
    RawContent        : HTTP/1.1 200 OK
                        Connection: keep-alive
                        Content-Length: 2
                        Date: Thu, 21 Nov 2019 17:50:11 GMT
    
                        OK
    Headers           : {[Connection, keep-alive], [Content-Length, 2], [Date, Thu, 21 Nov 2019 17:50:11
                        GMT]}
    RawContentLength  : 2
    
    

    Linux (bash)

    curl -i http://localhost:3000/servicesConnection
    
    

    Should output something like:

    HTTP/1.1 200 OK
    Date: Wed, 20 Nov 2019 20:00:39 GMT
    Connection: keep-alive
    Content-Length: 2
    
    OK
    
    

    5. Stopping the container

    You can stop your named container with:

    docker stop pas
