Example docker-compose system, based on .NET Core project and MySQL database (accessed with Dapper).
Dotnet Dockerfile and basic Docker setup based on SoftwareDeveloper.Blog introduction to Docker.
Docker-compose configuration used in this example is explained line by line in SoftwareDeveloper.Blog introduction to docker-compose.
if you want to see this example running, you can just type docker-compose up from solution directory.
If you want run this example but without attaching console, run docker-compose up in detach mode - docker-compose up -d.
If you have already composed system up, but then changed source code, you need to pass --build parameter, when running docker-compose up next time: docker-compose up --build.
Of course it can be used along with detach parameter.
When you want to clean up containers and networks created by docker-compose, just type docker-compose down from solution directory.
If you want to see if this example system works properly, just access in your browser following GET address - http://localhost:8080 and you should see following results taken from database:
[
{
"id": 1,
"name": "Dependency Injection Principles, Practices, and Patterns",
"description": "Book by Steven van Deursen and Mark Seemann"
},
{
"id": 2,
"name": "Agile Software Development, Principles, Patterns, and Practices",
"description": "Book by Robert C. Martin"
}
]If you see empty result, wait a while and try again - maybe MySQL database is not fully initialized yet.
To develop the application locally on your host machine but run all the supporting services via containers, run .script/bootstrap. This will run docker-compose up -d db to start the database in detached mode. The docker-compose.yml is configured to map localhost:3001 to db:3306 which your IDE launch config can use to connect to the datbase (.vscode/launch.json is pre-configured for this).
