You can set up PSA in the Docker engine using the automation script, which is available with the installation zip file. When you run the installation command, the script automatically builds the docker image and deploys PSA.

Supported Operating System 

• Linux (RHEL >=8, Amazon Linux, CentOS and Ubuntu)
• macOS with Intel processor  

• Windows
  

  Installing PSA using the automated script is not supported on Windows. To install PSA on Windows, see Deploy PSA Manually.

The following table illustrates the differences between installing PSA in Kubernetes and Docker:

Download the PSA Installation Files

Download the PSA installation zip file from the Cisco AppDynamics Download Center or from the beta upload tool. This file contains Docker files for sum-chrome-agent, sum-api-monitoring-agent, sum-heimdall, Helm charts, and automation scripts. To build an image for sum-chrome-agent, sum-api-monitoring-agent, and sum-heimdall, ensure that Docker is installed. You can download and install Docker from here if it is not installed.

(Optional) Configure Proxy Server

When you configure a proxy server, it applies to all the domains. Configure a proxy server by specifying the proxy server address on the application-onprem.yaml file. See Key-Value Pairs Configuration.

To bypass any domains from the proxy server, perform the following steps:

1. Open the application-onprem.yaml file.

2. Add the domain URLs in the noProxy field under proxyConfig:

   proxyConfig: apiMonitoringAgent: enabled: true proxyServer: <proxy-server-address> browserMonitoringAgent: enabled: true proxyServer: <proxy-server-address> heimdall: enabled: true proxyServer: <proxy-server-address> noProxy: enabled: true proxyServer: "<specify the domain URLs that you want to bypass separated by comma>"

   For example, proxyServer: "*abc.com,*xyz1.com,*xyz2.com"

   Domain URLs that you specify in noProxy are not redirected to the proxy server. You can add any number of domains in the noProxy field. All other unspecified domain URLs are redirected to the proxy server.

Deploy PSA in Docker 

1. Unzip the PSA installation zip file.

2. Run the following command to install PSA in a Docker engine:
   

   ./install_psa -e docker -v -u <Shepherd-URL> -a <EUM-account> -k <EUM-key> -c <location-code> -d <location-description> -t <location-name> -s <location-state> -o <location-country> -i <location-latitude> -g <location-longitude> -p <PSA-tag> -r <heimdall-replica-count> -z <agent-type> -m <chrome-agent_min/max-memory> -n <API-agent_min/max-memory> -x <chrome-agent_min/max-CPU> -y <API-agent_min/max-CPU> -w <heimdall_proxy_server>~<web_monitoring_proxy_server>~<api_monitoring_proxy_server> -B <bypass-proxy-domains> -q <ignite-persistence>

   A sample installation command looks like this: 
   

   ./install_psa -e docker -v -u <Shepherd-URL> -a <EUM-account> -k <EUM-key> -c DEL -d Delhi -t Delhi -s DEL -o India -i 28.70 -g 77.10 -p 23.5 -r 1 -z all -m 100Mi/500Mi -n 100Mi/100Mi -x 0.5/1.5 -y 0.1/0.1 -w http://testproxy-heimdall.net:3213~http://testproxy-chrome.net:3213~http://testproxy-api.net:3213 -B "www.test.com,*.appdynamics.com" -q true

The following table describes the usage of the flags in the command. Asterisk (*) on the description denotes mandatory parameters.

Monitor PSA

To monitor the CPU and memory usage of the Heimdall and Ignite containers, run the following command:

./monitoring_psa

Deploy PSA Manually

Perform the following steps:

1. Pull the agent docker images:
   

   docker pull appdynamics/heimdall-psa docker pull appdynamics/chrome-agent-psa docker pull appdynamics/api-monitoring-agent-psa

    

2. Navigate to ./docker-psa/appdynamics and update the following details in the onprem.yaml file:
   • Shepherd URL
   • EUM credentials
   • Registration location
   • Agent tag
     

     These are the configuration key-value pairs that you need to edit in the onprem.yaml file:

     Web Monitoring PSA:

     Configuration Key	Value
     chromeAgent > image	<agent-tag>
     shepherd > url	Shepherd URL
     shepherd > credentials	credentials
     shepherd > location	agent location
     proxyConfig > enabled	true Specify this field only if you are using the proxy server. Make the same change for Heimdall.
     proxyConfig > proxyServer	Proxy server URL

     API Monitoring PSA:

     Configuration Key	Value
     apiMonitoringAgent > image	<agent-tag>
     shepherd > url	Shepherd URL
     shepherd > credentials	credentials
     shepherd > location	agent location
     proxyConfig > enabled	true Specify this field only if you are using the proxy server. Make the same change for Heimdall.
     proxyConfig > proxyServer	Proxy server URL

3. Navigate to ./docker-psa and update the Heimdall tag in the docker-compose.yaml file.

   Configuration Key	Value
   heimdall > image	<heimdall-tag>

4. Perform Docker compose:

   docker-compose up -d

Upgrade PSA

Perform the following steps to upgrade PSA: 

1. Download and unzip the PSA installation zip file.

   The upgrade_psa -h command displays the parameters that you can specify.

2. Run the following command:

   ./upgrade_psa -d -v <PSA-release-tag>

The following table describes the usage of the flags in the command. The asterisk (*) on the description denotes a mandatory parameter.

Uninstall PSA

To uninstall PSA, run the following commands:

./uninstall_psa -e docker -p
