Install Container Management

The Container Management file is available as a downloadable bundle from the VMware Pulse IoT Center console. This section lists the steps to download and install Container Management.

Prerequisites

• Ensure that your Docker gateway is enrolled.
• Ensure that the Docker service is enabled and running on your gateway.

Procedure

1. Log in to the VMware Pulse IoT Center console UI.
2. From the top right of the home page, click the settings icon and click Downloads.
3. From the Downloads window, scroll down to the Container Management section and click Download against the container management bundle.
4. Using a linux machine, download the Container Management bundle to your local disk.
5. Create a campaign:
   1. Create a package specification YML file. The following example illustrates a sample package specification YML file:
      package-spec.yml

      root@photon2gw [ ~/code/iotc-clientd/deployment/campaign ]# cat package-spec.yml 
      package:
        name: container-management-deploy
        description: container management deploy for photon
        version: 1.0.0
        os: Linux
        architecture: x86_64
        manifest:
          headlessExecution: true
          lifecycle:
            - phase: execute
              action: data/campaign_install.sh
        attachments:
          - path: data/campaign_install.sh
          - path: data/iotc-client-x86_64-2.0.0.13.tar.gz
          - path: data/container-management.service

   2. Create an installation script. The following example illustrates a sample installation script using a Photon gateway:
      campaign_install.sh

      root@photon2gw [ ~/code/iotc-clientd/deployment/campaign ]# cat data/campaign_install.sh 
      #!/usr/bin/env bash
      #example campaign on a photon gateway
      
      logdir=/var/log/vmware
      mkdir -p $logdir
      
      logfile=$logdir/container_management_campaign_log.txt
      
      echo $(date "+%Y-%m-%d %H:%M:%S") Execution script started >> $logfile
      
      #ensure docker installed
      tdnf install docker -qy
      systemctl daemon-reload
      systemctl restart docker
      
      #clear staging dir
      rm -rf /tmp/iotc-client
      tar -xf $DATADIR/data/iotc-client-x86_64-0.0.13.tar.gz -C /tmp
      
      #execute install
      /tmp/iotc-client/install.sh
      
      #remove staging
      rm -rf /tmp/iotc-client
      
      echo $(date "+%Y-%m-%d %H:%M:%S") Execution script finished >> $logfile

   3. Create a campaign package. The following example illustrates a sample campaign package:

      root@photon2gw [ ~/campaign ]# ./package-cli package create ./package-spec.yml
       
      root@photon2gw [ ~/campaign ]# ls -al *.iotcp
      -rw-r----- 1 root root 68891 Jun 18 16:58 demo-1.0.0.iotcp

   4. Upload the campaign package to the VMware Pulse IoT server.

      root@photon2gw [ ~/campaign ]# ./package-cli upload package ./demo-1.0.0.iotcp <server address>

6. Run a campaign on your gateways using the uploaded package.
7. Verify that the Container Management package is running on your gateways.

Results

When Container Management starts, it sends the container environment properties and metrics to the gateways. The num-images, num-containers, and num-running-containers metrics are displayed for each gateway.
