Motivation:

To deploy existing .Net Core 3.1 microservices as docker containers; using docker-compose (manually created) spinning all microservices up.

Prerequisites

• Docker Desktop 4.14.1 (91661)
• Visual Studio 2019/2022

Intructions

• Start Docker Desktop

• Execute below command from commands prompt from the root directory

  docker-compose build
  docker-compose up

  Once done, clear the containers with below command

  docker-compose down

• Note: While working with SQL DB in docker image for the very first time,

Branches:

• sql-image: The DBs are hosted in mcr.microsoft.com/mssql/server:2019-latest container; mounted in local filesystem
• TODO: az-sql: The DBs are hosted in Azure SQL DBs

Dev Notes:

Issues encountered:

• Issue 1: Failed to compute cache key: ".csproj" not found while running docker-compose build,

  • https://stackoverflow.com/questions/66933949/failed-to-compute-cache-key-csproj-not-found
  • Solution - use build object instead of build dockerfileParentFolder

    build:
       context: .
       dockerfile: GloboTicket.Services.Discount/Dockerfile
    

• Issue 2: ...then an error occurred during the pre-login handshake.

  • dotnet/SqlClient#1479 (comment)
  • Solution: set TrustServerCertificate=True in your connection string

• Issue 3: Discount MS URL showing can't reach this page http://localhost:5007/api/discount/code/Awesome

  • Updated "applicationUrl": "http://localhost:5007" in launchSettings.json (https -> http)
  • Now URL shows proper response: http://localhost:5007/api/discount/code/Awesome

• Issue 4: Can't reach sql.discount DB from SSMS (outside of api.discount docker container)

• Issue 5: Font files not getting loaded

  Failed to load resource: the server responded with a status of 404 (Not Found) OpenSans-Bold.ttf:1
  Failed to load resource: the server responded with a status of 404 (Not Found) OpenSans-Regular.ttf:1

  • The file names are case-sensitive in linux based OS/docker-images. Updating the names properly in CSS fixes this issue.

Done:

• Use mssql server container for database and mount volumn
• Start other services with DB dependencies and start using Az Message Bus
• Provide config details from compose env file
• Fixed errors in Payment & Marketing microservices

TODO:

• Use docker-compose.override.yml

• Configure application to use https: Reference: https://medium.com/@woeterman_94/docker-in-visual-studio-unable-to-configure-https-endpoint-f95727187f5f

• Use JWT and OpenAuth
