Setting up AWS DynamoDB Local as macOS autostart service.

aws.DynamoDB.as.macOS.service.md

1. Download archive from "https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DynamoDBLocal.DownloadingAndRunning.html"

2. Unpack it to: /opt/aws/dynamodb

3. Create shell script: /opt/aws/dynamodb/dynamodb_local.sh.

   #!/bin/bash
   
   RootDirPath=$(cd "$(dirname "$0")"; pwd)
   cd "$RootDirPath"
   
   java -Djava.library.path="$RootDirPath/DynamoDBLocal_lib" -jar "$RootDirPath/DynamoDBLocal.jar" "$@"

4. Update PATH variable: export PATH="$PATH:/opt/aws/dynamodb"

5. Run dynamodb_local.sh -help

6. Run /opt/aws/dynamodb/dynamodb_local.sh -sharedDb -port 6320 -dbPath /opt/mca/dynamodb

7. Test the instance aws dynamodb list-tables --endpoint-url http://localhost:6320

8. Create file ~/Library/LaunchAgents/mca.dynamoDBLocal.plist

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
   <plist version="1.0">
   <dict>
       <key>Label</key>
       <string>mca.dynamoDBLocal</string>
       <key>LimitLoadToSessionType</key>
       <array>
           <string>Aqua</string>
           <string>Background</string>
           <string>LoginWindow</string>
           <string>StandardIO</string>
           <string>System</string>
       </array>
       <key>ProgramArguments</key>
       <array>
           <string>/opt/aws/dynamodb/dynamodb_local.sh</string>
           <string>-sharedDb</string>
           <string>-port</string>
           <string>6320</string>
           <string>-dbPath</string>
           <string>/opt/mca/dynamodb</string>
       </array>
       <key>RunAtLoad</key>
       <true/>
       <key>WorkingDirectory</key>
       <string>/opt/aws/dynamodb</string>
       <key>StandardErrorPath</key>
       <string>/opt/mca/dynamodb/dynamodb-stderr.log</string>
       <key>StandardOutPath</key>
       <string>/opt/mca/dynamodb/dynamodb-stdout.log</string>
   </dict>
   </plist>

9. Run as macOS service launchctl bootstrap user/`id -u` $HOME/Library/LaunchAgents/mca.dynamoDBLocal.plist

10. Get status: launchctl print user/`id -u`/mca.dynamoDBLocal

11. Unload macOS service if not needed anymore: launchctl bootout user/`id -u`/mca.dynamoDBLocal
