Cosmos Experiment

Prereq's:

• Have docker-compose installed (Ubuntu)

  sudo snap install docker
  sudo groupadd docker
  sudo gpasswd -a $USER docker
  newgrp docker
  

• add a hostname for the local cosmosdb for TLS goodness

  sudo vi /etc/hosts
  
    [ append the following line ]
    127.0.0.1       cosmosdb
  

• launch the emulator and copy its self-signed certificate

  cd containers/docker-cosmosdb
  ./launchEmulator.sh
  
  curl -k https://cosmosdb:8081/_explorer/emulator.pem > ~/emulatorcert.crt
  sudo mv ~/emulatorcert.crt /usr/local/share/ca-certificates/
  update-ca-certificates
  

Running:

• launch the Cosmos DB Emulator

  cd containers/docker-cosmosdb
  ./launchEmulator.sh
  

• (in a separate terminal) run Woldrich.CosmosService

  dotnet run --project ./services/Woldrich.CosmosService/Woldrich.CosmosService.csproj
  

• (in a separate terminal) initialize the local Cosmos DB - this only needs to be run once or whenever you blow away the database that lives in containers/docker-cosmosdb/cosmosdata.

  cd services/Woldrich.CosmosService
  ./initializeDatabase.sh
  

• insert a row by POST'ing to the service:

  cd services/Woldrich.CosmosService
  ./postRecord.sh
  

  The response that comes back should have a URL of the resource that was created in the Location header that works as a GET endpoint

• You can explore the data in local Cosmos at the following:
